Avionics Hardware EngineerWe are hiring Avionics Hardware Engineers to own flight-critical electronics across design, bring-up, test, and integration. This role is intended for engineers with experience in complex electronic systems who can take responsibility for avionics subsystems and operate effectively in a high-tempo development environment. Engineers in this role may own areas such as motor controllers, avionics backplanes, power distribution, or outward-facing avionics test and integration.
Responsibilities- Own avionics hardware from architecture and schematic design through PCB layout, bring-up, and production support
- Drive design decisions including component selection, interfaces, and system tradeoffs
- Lead hardware bring-up, debugging, and root-cause analysis across lab, integration, and flight test
- Collaborate cross-functionally to ensure avionics hardware meets performance, reliability, and mission requirements
- Define and execute hardware validation strategies appropriate to development and flight maturity
- Produce clear technical documentation covering designs, test results, and engineering changes
- Partner with manufacturing and suppliers to transition hardware from prototype to production
- Continuously improve designs based on test results, field data, and evolving requirements
Basic Qualifications- Bachelor's degree in electrical engineering or related field
- Proven end-to-end ownership of avionics or high-reliability electronic hardware
- Strong experience with PCB design, bring-up, and lab debugging
- Ability to operate autonomously and drive hardware issues to closure
Preferred Qualifications- Avionics, aerospace, missile, space, automotive, or defense hardware experience
- Experience with motor controllers, backplanes, power electronics, or flight hardware
- Familiarity with MIL-STD or aerospace hardware standards (e.g., DO-254 exposure)
