Summary

Job Description

This engineer for mission systems will serve as a senior technical leader responsible for the end-to-end engineering of mission systems on advanced next-generation unmanned aircraft, including RF and optical/infrared sensors (Radar, IRST, EO/IR, etc..), Electronic Warfare, and associated support systems. This individual will shape the technical direction of programs, ensuring that the aircraft delivers decisive mission capabilities through robust, integrated, and certifiable system designs.

In this role, the engineer will drive mission system architectures, lead requirement development and allocation, and oversee system integration from concept through flight test and fielding. They will ensure that mission systems, avionics, and weapons are seamlessly integrated into the aircraft while meeting mission performance, safety, airworthiness, and compliance objectives.

What you'll do:

  • Develop mission systems requirements and architectures to ensure overall system effectiveness
  • Select mission system baselines through make vs buy trades and vendor engagements
  • Develop the integration & test verification plan to include resources from bench-level hardware-in-the-loop (HIL) to flight test
  • Define mission system software architectures including baseline processing and advanced algorithm development
  • Drive trade studies and system-of-systems analysis to balance performance, cost, and schedule
  • Serve as a technical subject matter expert for mission systems engineering across the aircraft program
  • Ensure compliance with MIL-HDBK-516C, DO-178C, DO-254, and related standards
  • Collaborate with program management to de-risk architectures and ensure technical maturity gates are met
  • Interface with customers, partners, and suppliers to align system requirements and certifications
