About NiSource

NiSource is one of the largest fully regulated utility companies in the United States, serving approximately 3.2 million natural gas customers and nearly 500,000 electric customers across six states through its two primary subsidiaries: Columbia Gas and NIPSCO (Northern Indiana Public Service Company). Headquartered in Merrillville, Indiana, NiSource operates a vast network of natural gas distribution, transmission, and storage infrastructure while also generating and distributing electricity in northern Indiana. The company is in the midst of an ambitious energy transition, retiring coal-fired generation assets and investing heavily in renewable energy sources including wind, solar, and battery storage — a shift clearly reflected in roles like Manager of New Power Generation Construction. With roughly 7,600 employees, NiSource occupies a distinctive middle ground: large enough to offer robust benefits, career mobility across multiple states, and meaningful infrastructure projects, yet small enough that individual contributors can have visible impact on operations and strategy. The culture emphasizes safety above all else — a core value reinforced after the 2018 Merrimack Valley gas incident that fundamentally reshaped the company's safety practices, leadership structure, and operational philosophy. Today, NiSource positions itself as a safety-first, people-driven organization committed to affordable, reliable, and clean energy. Employees commonly describe the work environment as mission-oriented, with strong union representation in field roles and increasing flexibility (including hybrid arrangements) for corporate and analytical positions. For professionals who want stable, meaningful careers powering communities through a historic energy transition, NiSource offers a compelling combination of purpose, stability, and growth.

Application Process

1
Explore Open Positions on NiSource's Workday Careers Portal
Visit NiSource's dedicated careers page at nisource.wd1.myworkdayjobs.com to browse current openings. With only around 31+ open positions at any given time, NiSource hires selectively — so when a role matching your skills appears, act quickly. Use the search filters to narrow by location (NiSource operates in Indiana, Ohio, Virginia, Kentucky, Pennsylvania, and Maryland), job family, and whether the role is hybrid or on-site.
2
Create or Log Into Your Workday Candidate Profile
NiSource uses Workday (WD1 instance) as its applicant tracking system, so you'll need to create a candidate account to apply. Complete your profile thoroughly — Workday allows you to store your resume, work history, education, and certifications, which can auto-populate future applications. If you've previously applied to any company using Workday, you may be able to sign in with existing credentials, though NiSource's instance is company-specific.
3
Tailor Your Application Materials to the Specific Role
Given NiSource's small number of open positions and specialized workforce needs — spanning utility field operations, engineering, finance, tax, and emerging technology like drone programs — generic applications rarely succeed. Customize your resume to mirror the exact language in the job posting, emphasizing relevant utility industry experience, regulatory knowledge, or technical certifications. Include a cover letter if the system permits, particularly for corporate hybrid roles like SEC Financial Reporting Accountant or Senior Category Specialist where competition may be higher.
4
Complete All Workday Application Questionnaires
NiSource's Workday portal typically includes screening questions specific to each role, covering topics like required certifications (CDL, CPA, PE license), willingness to travel or relocate across their service territory, and eligibility for roles requiring safety-sensitive clearances. Answer every question completely and honestly — incomplete applications are commonly filtered out before a recruiter ever sees them. Some field roles like Leakage Inspector may include additional questions about physical requirements and availability for on-call rotations.
5
Initial Recruiter Review and Phone Screen
After submission, a NiSource recruiter will review your application against the role's requirements. Because NiSource is a regulated utility, many roles have strict qualification requirements (engineering licenses, specific years of utility experience, safety certifications) that serve as hard filters. If selected, expect an initial phone screen of 20-30 minutes focusing on your background, interest in the utility sector, salary expectations, and logistical fit including location and hybrid schedule preferences.
6
Technical or Panel Interview Round
NiSource commonly conducts one to two rounds of deeper interviews, often including a panel of the hiring manager, a team member, and sometimes an HR business partner. For technical roles like Project Cost Analyst or Lead Design Engineering, expect scenario-based questions related to utility project management, regulatory compliance, or financial modeling specific to rate cases and capital planning. Behavioral interview questions aligned with NiSource's core values — particularly safety, collaboration, and integrity — are consistently reported across role types.
7
Background Check, Pre-Employment Screening, and Offer
As a regulated utility operating critical infrastructure, NiSource conducts thorough background checks on all hires, and many field-based positions require drug screening, physical fitness assessments, and motor vehicle record reviews. The offer stage typically involves a formal letter through Workday with details on compensation, benefits, start date, and any relocation or signing incentives. NiSource's benefits package commonly includes pension plans, 401(k) matching, tuition reimbursement, and comprehensive health coverage — benefits that reflect the utility industry's traditionally strong total compensation model.

Resume Tips for NiSource

critical

Lead with Utility Industry and Regulated Environment Experience

NiSource operates in a heavily regulated industry governed by state public utility commissions and federal agencies like PHMSA and FERC. If you have experience in regulated utilities, energy, or similar industries (telecommunications, water), make this immediately visible in your resume summary and work experience sections. Even for corporate roles like Tax Analyst or SEC Financial Reporting Accountant, referencing utility-specific regulatory frameworks (rate cases, GAAP for regulated entities, ASC 980) signals that you understand NiSource's operating context and will ramp up faster.

critical

Mirror NiSource's Exact Job Posting Terminology in Your Resume

Workday's parsing engine matches candidate profiles against job requisition keywords, so use the precise language from NiSource's posting. If the listing says 'New Power Generation Construction,' use that exact phrase rather than paraphrasing as 'renewable energy projects.' If a role references 'UAS Drone Program,' include 'UAS' and 'drone' as terms rather than only 'unmanned aerial systems.' This direct mirroring ensures Workday's algorithm ranks your application favorably during the initial automated screening stage.

critical

Emphasize Safety Credentials, Training, and Culture Alignment

Safety is NiSource's paramount organizational value, deeply embedded since the company's operational transformation following the 2018 Merrimack Valley incident. Regardless of whether you're applying for a Leakage Inspector or a Financial Analyst role, include any safety-related training, certifications (OSHA, PSM, SMS), or experience fostering safety culture. For field roles, list specific safety certifications and incident-free work records. For corporate roles, reference experience with safety management systems, compliance reporting, or risk management frameworks.

recommended

Quantify Impact Using Metrics Relevant to Utility Operations

NiSource manages billions in capital infrastructure projects, serves millions of customers, and operates under strict regulatory timelines. Frame your accomplishments in terms that resonate: miles of pipeline inspected or replaced, capital project budgets managed, regulatory filing deadlines met, percentage improvements in operational efficiency, or customer accounts managed. A bullet point like 'Managed $45M capital replacement program across 200 miles of distribution pipeline, completing 98% of scope on schedule' speaks NiSource's language far more effectively than generic project management descriptions.

recommended

Use a Clean, Single-Column Format Optimized for Workday Parsing

Workday's resume parser handles standard formatting well but can struggle with multi-column layouts, text boxes, headers/footers containing critical information, and heavily designed templates. Use a single-column format with clear section headers (Experience, Education, Certifications, Skills), standard fonts like Calibri or Arial, and submit as a .docx or .pdf file. Avoid embedding your name or contact information in a header element, as Workday may not extract it correctly — place all contact details in the main body of the document.

recommended

Highlight Cross-Functional and Multi-State Experience

NiSource operates across six states with two distinct subsidiary brands (Columbia Gas and NIPSCO), meaning many roles involve cross-functional coordination and multi-jurisdictional awareness. If you've worked across state lines, managed projects spanning multiple regulatory jurisdictions, or collaborated across departments (engineering, finance, operations, legal), feature this prominently. This is especially relevant for managerial roles like Manager Project Engineering, where the ability to navigate different state regulatory environments and coordinate diverse teams is essential.

recommended

Include Relevant Professional Licenses and Technical Certifications Prominently

Many NiSource roles require or prefer specific credentials: PE licenses for engineering roles, CPA for accounting positions, PMP for project management, CDL for field operations, and FAA Part 107 certification for the UAS Drone Program role. Create a dedicated 'Licenses & Certifications' section near the top of your resume rather than burying these credentials in education or skills sections. Workday's screening questions often map directly to these qualifications, and recruiters scanning quickly need to verify them at a glance.

Reference Energy Transition and Renewable Energy Experience

NiSource is actively transitioning its generation portfolio from coal to renewables, investing in wind, solar, and battery storage projects. Multiple current openings relate directly to 'New Power Generation Construction.' If you have experience with renewable energy project development, PPA negotiations, interconnection processes, or clean energy regulatory proceedings, this positions you as aligned with NiSource's strategic direction. Even tangential experience — such as sustainability reporting, environmental compliance, or emissions reduction initiatives — adds value.

ATS System: Workday (WD1 Instance)

NiSource uses Workday's WD1 cloud-based recruiting module to manage all job postings, candidate applications, and hiring workflows. Workday parses uploaded resumes to auto-populate candidate profile fields and uses keyword matching to help recruiters filter and rank applicants against specific job requisition criteria. Unlike some ATS platforms, Workday also allows candidates to build persistent profiles that carry forward across multiple applications within NiSource's system.

Submit your resume as a .docx or standard .pdf — Workday's parser handles these formats most reliably and can extract structured data from them
After Workday auto-populates your profile from your resume upload, manually review every field for accuracy — parsing errors in job titles, dates, and company names are common and can misrepresent your experience
Use exact keywords and phrases from NiSource's job posting throughout your resume, including specific tools (SAP, Oracle, GIS, SCADA), certifications, and NiSource-specific terminology like 'regulated utility' or 'capital program management'
Avoid tables, graphics, icons, multi-column layouts, and text boxes — Workday's parser reads content linearly and may scramble or skip information embedded in complex formatting elements
Complete all optional fields in your Workday profile including skills, certifications, and preferred work locations across NiSource's six-state territory — recruiters use these fields to search for candidates for future roles even if your initial application doesn't result in a match
Ensure your contact information (name, email, phone) appears in the main body of your resume, not in headers or footers, which Workday may not parse correctly
When answering screening questionnaire questions, be thorough and specific — Workday allows recruiters to set auto-disposition rules that can reject applications based on disqualifying answers to required questions

Interview Culture

NiSource's interview process reflects its identity as a safety-focused, regulated utility where precision, reliability, and cultural alignment matter as much as technical skill.

The process typically involves two to three stages: an initial phone screen with a recruiter from the talent acquisition team, followed by one or two rounds of interviews with the hiring manager and a panel that may include team members, cross-functional partners, and an HR business partner. For corporate and hybrid roles — such as Tax Analyst, SEC Financial Reporting Accountant, or Senior Financial Analyst — interviews commonly blend behavioral questions with technical assessments. Expect competency-based questions framed around NiSource's core values: safety, integrity, respect, and collaboration. Questions like 'Describe a time you identified and escalated a safety or compliance concern' or 'How do you prioritize competing regulatory deadlines?' are characteristic of NiSource's interview style. Financial and accounting candidates should be prepared to discuss utility-specific topics like regulatory accounting standards, rate case support, and capital versus O&M classification. For engineering and field operations roles — such as Leakage Inspector, Lead Design Engineering, or Project Engineering Manager — interviews tend to be more technically rigorous, with scenario-based questions about pipeline integrity, construction management, or distribution system operations. Candidates with direct utility field experience have a distinct advantage, though NiSource has historically valued transferable skills from adjacent industries like oil and gas, construction, or municipal infrastructure. NiSource's interviewers commonly assess for what might be called 'utility temperament': a steady, detail-oriented approach to work, comfort with regulatory scrutiny, and genuine commitment to public safety. The company's post-2018 cultural transformation means interviewers pay particular attention to how candidates talk about safety — not as a compliance checkbox, but as a personal and professional value. Demonstrating that you understand the weight of operating critical infrastructure that communities depend on daily goes a long way. Virtual interviews via Microsoft Teams are common for initial rounds, with final-round or on-site interviews at NiSource facilities depending on the role's location. The overall tone is professional but approachable — NiSource prides itself on a respectful, Midwestern work culture where people are expected to be straightforward, collaborative, and accountable.

Deep commitment to safety culture — not just compliance, but a personal orientation toward identifying hazards, speaking up about risks, and prioritizing the well-being of coworkers and communities served
Utility industry or regulated environment experience, including familiarity with state public utility commission processes, PHMSA pipeline safety regulations, or FERC oversight frameworks
Technical proficiency relevant to specific roles — whether that's SAP/Oracle for finance positions, GIS and SCADA systems for engineering roles, or FAA Part 107 certification for the drone program
Cross-functional collaboration skills suited to a complex organization operating two major subsidiaries across six states with diverse regulatory environments and stakeholder groups
Adaptability and enthusiasm for the energy transition, particularly experience with or interest in renewable energy, decarbonization strategies, and new power generation technologies
Analytical rigor and attention to detail — critical in a regulated utility where financial reporting, engineering specifications, and compliance documentation face external regulatory scrutiny
Long-term career orientation and community-mindedness, reflecting NiSource's mission of serving customers and communities reliably for decades, not just quarters

Frequently Asked Questions

How long does the NiSource hiring process typically take from application to offer?

Based on patterns reported by candidates, NiSource's hiring process commonly takes four to eight weeks from application submission to offer, though this varies significantly by role type. Field operations positions like Leakage Inspector may move faster due to operational urgency, while specialized corporate roles like SEC Financial Reporting Accountant or Manager-level engineering positions may take longer as they involve multiple interview rounds and broader stakeholder input. Background checks for utility roles — which can include criminal history, drug screening, motor vehicle records, and credential verification — add additional time after the verbal offer stage. Setting up job alerts on NiSource's Workday portal and applying early when postings appear can help ensure your application receives attention before the role's candidate pool is filled.

Does NiSource require a cover letter with applications?

NiSource's Workday portal does not always include a mandatory cover letter upload field for every position, but submitting one when the option is available can differentiate your application — particularly for corporate, hybrid, and leadership roles. A strong cover letter for NiSource should directly address the specific role's requirements, demonstrate your understanding of the regulated utility environment, and articulate why NiSource's mission of safe, reliable, affordable energy resonates with you personally. Reference the company's energy transition initiatives or safety transformation to show you've researched NiSource beyond the job description. For field operations roles, a cover letter is less commonly expected but can still help if you're transitioning from a related industry and need to explain how your experience translates.

What format should I use for my resume when applying through NiSource's Workday system?

Submit your resume as a .docx (Microsoft Word) or a standard .pdf file for optimal parsing by NiSource's Workday WD1 system. Use a clean, single-column layout with clearly labeled section headers, standard fonts (Calibri, Arial, Times New Roman), and conventional formatting. Avoid tables, text boxes, multi-column designs, infographics, or images — Workday reads content linearly and may misinterpret or completely skip information embedded in complex formatting elements. Place your name, email, and phone number in the main document body rather than in headers or footers. After uploading, always check that Workday has correctly parsed your information into the profile fields and manually correct any errors before submitting your application.

Does NiSource offer remote or hybrid work arrangements?

Yes, NiSource offers hybrid work arrangements for many corporate and professional roles, as indicated by postings like 'Tax Analyst (hybrid)' and 'Hybrid Senior or Lead Financial Analyst.' These hybrid positions typically require some regular on-site presence at a NiSource office — most commonly in Merrillville, Indiana (headquarters) or Columbus, Ohio — combined with remote work flexibility. However, a significant portion of NiSource's workforce is in field operations, engineering, and construction roles that are inherently on-site due to the physical nature of gas distribution, pipeline inspection, and power generation work. When applying, check each posting carefully for location requirements and hybrid eligibility, as this varies significantly by role and business unit.

What experience level does NiSource typically require for open positions?

NiSource's job postings span a range of experience levels, from entry-level field operations roles to senior leadership and management positions. Based on current and recent postings, many roles require three to seven years of relevant experience, with manager-level positions typically requiring eight or more years including supervisory experience. Roles like Leakage Inspector may accept candidates with less experience provided they hold required certifications or are willing to complete training programs. For specialized positions like SEC Financial Reporting Accountant or Senior Category Specialist, NiSource typically seeks candidates with demonstrated expertise in their discipline plus familiarity with utility or regulated industry environments. If a posting lists a range of titles (e.g., 'Senior or Lead Financial Analyst'), this often means NiSource will consider candidates at different seniority levels and adjust the offer accordingly.

How should I prepare for a NiSource interview?

Start by deeply researching NiSource's two operating subsidiaries (Columbia Gas and NIPSCO), the company's safety transformation story, and its renewable energy transition strategy — these are foundational topics that commonly arise in interviews. Prepare behavioral examples using the STAR method (Situation, Task, Action, Result) that demonstrate safety awareness, integrity, collaboration, and analytical rigor. For technical roles, review industry-specific knowledge relevant to your position: pipeline integrity management for field roles, regulatory accounting standards for finance positions, or project management methodologies for engineering roles. Practice articulating why you specifically want to work in the utility industry and at NiSource — interviewers at mission-driven companies notice when candidates have genuine enthusiasm for the sector versus applying broadly. Finally, prepare thoughtful questions about the team's current priorities, how the role supports NiSource's energy transition goals, and what success looks like in the first year.

What benefits does NiSource offer employees?

NiSource offers a benefits package that reflects the utility industry's tradition of strong total compensation. Based on publicly available information, benefits commonly include comprehensive medical, dental, and vision insurance; a defined benefit pension plan (increasingly rare in the private sector); 401(k) with company matching; tuition reimbursement for continuing education; paid time off and holidays; employee assistance programs; and life and disability insurance. NiSource also provides safety equipment and ongoing training for field personnel. The company has been recognized for its wellness programs and employee resource groups supporting diversity and inclusion. Specific benefit details and eligibility may vary by role type (union vs. non-union), employment status, and subsidiary, so confirm details during the offer stage.

Can I apply to multiple positions at NiSource simultaneously?

Yes, NiSource's Workday system allows candidates to apply to multiple open positions, and doing so can be a smart strategy given the company's relatively small number of active postings at any given time. However, tailor each application specifically to the role — submitting the same generic resume and responses to multiple positions can actually hurt your candidacy if recruiters notice a lack of customization. Focus on roles where your qualifications genuinely align with the stated requirements, and adjust your resume keywords and cover letter focus for each position. Your Workday candidate profile persists across applications, so invest time upfront in making it comprehensive and accurate.

What is NiSource's approach to diversity and inclusion in hiring?

NiSource publicly commits to building a diverse and inclusive workforce, with stated initiatives including employee resource groups, diversity-focused recruitment partnerships, and leadership accountability for inclusion metrics. The company has been recognized by organizations like the Human Rights Campaign and Forbes for its workplace inclusion practices. In practical terms, NiSource's interview panels commonly include diverse representation, and the company actively recruits from veteran, minority-serving, and women-in-energy networks. Candidates who demonstrate cultural competence, collaborative mindset, and respect for diverse perspectives align well with NiSource's stated values. The company's Equal Employment Opportunity statements are prominently featured across their job postings, reflecting the regulated utility industry's compliance obligations and NiSource's broader commitment to equitable hiring.
