Hiring Manager

Collins Aerospace / RTX

Aberdeen Proving Ground, MD

Dear Hiring Manager,

I am writing to express my interest in the Senior Systems Engineer position supporting the Precision Navigation (PNav) and Identify Friend or Foe (IFF) product lines. With over 15 years of experience in systems integration, hardware/software testing, and verification for mission-critical DoD programs, I bring a strong background in radio communications, system-level test development, and requirements-based verification that aligns directly with the needs of your Systems Engineering Test team.

At ASRC Federal, I led major test and evaluation efforts for the Army’s CPCE Display Viewer Application, developing end-to-end test procedures, conducting functional and performance testing, and ensuring requirements traceability in alignment with DoD T&E standards. I worked closely with developers, cybersecurity teams, and system administrators to troubleshoot integration issues and deliver high-quality systems ready for certification. My experience supporting Army systems and adhering to STIG compliance and cybersecurity validation directly complements Collins Aerospace’s rigorous engineering environment.

Additionally, my work at Netwerx testing SINCGARS SRDP radios provided hands-on experience with radio and communication systems similar to those used in IFF and PNav platforms. This included signal analysis, hardware/software verification, environmental testing, and defect resolution with engineering leads — skills that translate strongly to backend IFF integration and test.

I am particularly drawn to this role because it combines systems engineering, test leadership, and mission-focused integration work. With my Active Secret clearance, technical background, and commitment to rigorous system validation, I am confident in my ability to contribute immediately to your IFF product line efforts.

Thank you for your consideration. I would welcome the opportunity to discuss how my experience in DoD systems integration, radio testing, and requirements verification can support your mission at Collins Aerospace.

Sincerely,

Andy K. A. Hau
