Resume Tips for Shield AI

Critical Highlight U.S. Citizenship and Clearance Status Prominently

Many Shield AI roles require U.S. citizenship and security clearance eligibility due to the defense nature of the work. If applicable, clearly state your citizenship status and any active or prior security clearances near the top of your resume. This is commonly one of the first things recruiters screen for, and omitting it may cause your application to be deprioritized or filtered out during initial review.

Critical Mirror Keywords from the Job Description

Lever's ATS, like most systems, relies on keyword matching to help recruiters filter and search candidates. Carefully review the job posting and incorporate relevant technical terms, tools, programming languages, certifications, and methodologies directly into your resume. For example, if a role mentions 'embedded firmware,' 'power electronics,' 'GD&T,' or 'MATLAB,' ensure these exact terms appear in your experience or skills sections where truthfully applicable. Avoid keyword stuffing, but be deliberate about alignment.

Critical Quantify Impact with Metrics and Results

Shield AI operates in a results-oriented, engineering-heavy environment. Rather than listing job duties, frame your experience in terms of measurable outcomes. For example: 'Reduced inspection cycle time by 30% through implementation of automated quality checks' or 'Designed power distribution system for UAV platform supporting 15kW peak load.' Quantified achievements demonstrate the kind of tangible impact Shield AI values in its fast-paced, mission-critical work.

Critical Emphasize Relevant Domain Experience

Shield AI works across autonomous systems, AI/ML, aerospace, defense, and advanced manufacturing. Tailor your resume to emphasize experience in these domains. If you've worked on UAVs, autonomous vehicles, military systems, avionics, or similar technologies, make this experience prominent. Even adjacent experience—such as robotics, control systems, or real-time embedded systems—should be highlighted with clear connections to Shield AI's mission areas.

Use a Clean, ATS-Friendly Format

Lever parses resumes to extract structured data, so use a clean format with standard section headers like 'Experience,' 'Education,' 'Skills,' and 'Certifications.' Avoid tables, multi-column layouts, headers/footers with critical information, or heavy graphics that may not parse correctly. Use standard fonts and submit in PDF format unless the application specifically requests DOCX. Ensure your contact information is in the main body of the document, not in a header or footer.

Include Relevant Certifications and Technical Skills

For roles like Receiving Quality Inspector, Manufacturing Planner, or Electrical Engineer, specific certifications can set you apart. Include certifications such as IPC standards, AS9100, Six Sigma, J-STD soldering certifications, or relevant EIT/PE licenses. For software roles, mention specific frameworks, languages (C, C++, Python, Rust), and tools (ROS, Docker, CI/CD pipelines) that align with the job requirements. A dedicated 'Technical Skills' section helps both ATS parsing and quick recruiter scanning.

Demonstrate Cross-Functional Collaboration

Shield AI's job listings frequently reference working across teams—software, hardware, test, and integration. Highlight experiences where you collaborated across disciplines, led cross-functional projects, or served as a technical liaison between teams. This is particularly important for senior and staff-level roles where systems thinking and integration are key responsibilities.

Show Passion for the Mission

While a resume is primarily a professional document, Shield AI's culture places high value on mission alignment. If you have relevant military service, volunteer work with defense organizations, or personal projects related to autonomous systems or AI, consider including a brief mention. A concise 'Summary' or 'Objective' statement at the top of your resume that connects your career trajectory to Shield AI's mission of protecting service members can be a differentiator.
