Controls Engineer Resume Guide — How to Write a Resume That Gets Interviews
The BLS projects 11% employment growth for industrial engineers and 7% for electrical engineers through 2034, with median salaries of $101,140 and $111,910 respectively [1][2]. Controls engineers — who span both disciplines — are the professionals who make automated manufacturing, process control, and building systems actually work. With 25,200 annual openings for industrial engineers alone and manufacturing reshoring accelerating across the U.S., experienced controls engineers with PLC programming, SCADA integration, and industrial networking skills are in exceptional demand [1].
Key Takeaways
- Lead with your PLC platforms (Allen-Bradley/Rockwell, Siemens, Mitsubishi, Omron) and programming languages (Ladder Logic, Structured Text, Function Block) — these are the primary ATS keywords [3].
- Quantify automation outcomes: downtime reductions, throughput increases, OEE improvements, energy savings, and system uptime percentages.
- Specify your industry vertical (automotive, pharmaceutical, food and beverage, oil and gas, water/wastewater) because controls requirements are highly industry-specific.
- Include networking protocols (EtherNet/IP, PROFINET, Modbus, OPC UA) and safety standards (SIL, IEC 62443) — these differentiate controls engineers from general electricians.
- Reference ISA and IEC standards compliance to demonstrate professional rigor.
What Do Recruiters Look For?
Controls engineering recruiters evaluate platform expertise, commissioning experience, and troubleshooting capability [3]. According to the International Society of Automation (ISA), the most competitive controls engineers demonstrate the ability to design, program, commission, and support automated systems from initial concept through production handoff [4].
For manufacturing facilities, recruiters prioritize PLC/HMI programming depth, motion control experience, and the ability to troubleshoot production issues under time pressure. The difference between a controls engineer who can debug a faulted servo drive at 2 AM during a production run and one who needs to call the vendor is the difference between getting hired and getting passed over.
For system integrators, project management capability matters as much as programming skill. Integrators want engineers who can manage project scopes, customer relationships, and commissioning timelines while delivering clean, documented code.

Common Resume Mistakes
- Not specifying PLC platforms — "PLC programming experience" is generic. Name Allen-Bradley ControlLogix, Siemens S7-1500, or Mitsubishi iQ-R with specific software (Studio 5000, TIA Portal).
- Missing quantified automation outcomes — Throughput increases, downtime reductions, OEE improvements, and changeover time savings prove engineering value.
- Ignoring networking protocols — EtherNet/IP, PROFINET, Modbus, and OPC UA are critical differentiators that separate controls engineers from electricians.
- No mention of safety system experience — SIL ratings, GuardLogix, and safety PLC experience are increasingly required. Include them if applicable.
- Listing hardware only, not projects — Recruiters want to see what you built, not just what tools you used. Describe the system, the complexity, and the outcome.
- Omitting commissioning experience — On-site startup, debugging, and customer handoff experience demonstrates real-world capability that cannot be learned in a classroom.
- No industry context — Pharmaceutical controls (21 CFR Part 11) differs from automotive (IATF 16949). Specify your industry vertical.

FAQ
Q: Allen-Bradley or Siemens — which should I emphasize? A: Allen-Bradley/Rockwell dominates the North American market. Siemens dominates in Europe and is growing in North America. List both if you have experience with both; emphasize whichever matches the job posting [3].
Q: Is a PE license important for controls engineers? A: Less critical than in civil or structural engineering, but increasingly valued for senior roles, especially in regulated industries (oil and gas, power generation) [5].
Q: Should I include my PLC code on a portfolio site? A: Be cautious — most PLC code is proprietary. You can describe architectures, show HMI screenshots (with permission), or share personal training projects.
Q: How do I transition from electrician to controls engineer? A: Emphasize troubleshooting experience, electrical panel work, and any PLC programming exposure. Add formal PLC training (Rockwell or Siemens courses) and demonstrate programming capability through personal projects.
Q: Is cybersecurity experience valuable for controls engineers? A: Increasingly critical. IEC 62443 compliance and OT network security are becoming standard requirements, especially in critical infrastructure sectors.
Q: What resume length is appropriate? A: One page for under 10 years. Two pages for engineering managers or senior engineers with extensive project portfolios and safety system design experience.
