The Environmental Effects Engineering (EEE) organization at Collins Aerospace is seeking a motivated Electrical Engineer to support the Nuclear Effects Survivability Team’s efforts. In this role, you’ll work across key stages of the product lifecycle, including requirements development, electrical design, hardware integration, and test verification/validation. This position requires you to independently manage multiple projects and technical tasks and will require Domestic travel (25%) with some foreign travel possible.

In this role, you will be a key contributor, applying your electrical testing experience to support parts-level, circuit-level, and system-level radiation effects testing that will directly impact certification of Collins Aerospace product lines.

Your primary responsibilities will include planning, executing, and supporting nuclear radiation characterization testing of electronics used in radio and display systems. This work ensures survivability in specialized environments/effects such as Total Ionizing Dose (TID), Neutron Displacement Damage (NDD), Gamma Dose Rate (DR), and Single Event Effects (SEE).

You will be expected to help prepare clear, well‑supported technical documentation, contribute to design reviews, and advise on risk mitigation strategies as part of a cross-disciplinary team.

A motivated engineer will thrive here, supported by deep subject‑matter expertise and trusted with meaningful responsibility from day one. You’ll have the autonomy to innovate while directly influencing product robustness. If you’re energized by technical depth, hands‑on problem‑solving, and opportunities to grow while supporting a premier engineering capability, this role is a strong fit.
