• Provide clear, data‑driven technical recommendations and status to program management and customer stakeholders.
• Develop and maintain integration plans, test procedures, and technical documentation in support of audits, reviews, and configuration control.
• Mentor junior engineers and promote best practices in integration, test, and defect management.

Basic Qualifications:

• Must have a Bachelors of Science degree in a STEM field and at least 8 years of relevant military / professional experience, OR a Master's Degree in a STEM field and at least 6 years of relevant military / professional experience, OR a PhD and at least 4 years of relevant military / professional experience
• Experience leading small technical teams or acting as a technical lead for integration or test efforts.
• Must have experience in software/system integration and test, including lab‑based integration (SIL/HWIL or similar).
• Must have experience with defect / discrepancy management, requirements tracing, and test case development.
• Must have an active US Government Secret or higher clearance (with a background investigation completed within the last 6 years or currently enrolled into Continuous Evaluation).

Preferred Qualifications

• Experience on RQ‑4, other UAS platforms, or mission systems in a CLS or sustainment environment.
• Experience with GHED (or similar defect/backlog management tools) and structured backlog grooming practices.
• Experience with regression test strategy, test automation, and continuous integration concepts.
• Familiarity with FMS customer environments and expectations.
