About the role

What You'll Do

  • Perform System Architecture & Design: Develop and refine the system architecture for the next gen UAS, ensuring seamless integration of avionics, autonomy, propulsion, sensor payloads, and mission systems.
  • Define and document system-level behavior, including modes, states, transitions, and fault responses.
  • Support safety analyses (FHA, FMEA, FTA) by defining behavior under fault conditions.
  • Define and Manage System Requirements: Establish top-level requirements, decompose them into subsystems, and maintain traceability across the development lifecycle.
  • Autonomy & AI Integration: Work closely with autonomy and software teams to integrate AI-driven flight control, decision-making, and mission execution capabilities.
  • Model-Based Systems Engineering (MBSE): Utilize SysML, DOORS, or other MBSE tools to create digital system models, conduct trade studies, and optimize system performance.
  • Risk Management & Trade Studies: Conduct trade studies to evaluate design alternatives, assess technical risks, and ensure the best engineering solutions for mission effectiveness.
  • Stakeholder & Customer Engagement: Work closely with DoD stakeholders, industry partners, and government agencies to align system capabilities with operational requirements.
  • Cross-Functional Collaboration: Partner with hardware, autonomy, software, propulsion, and flight operations teams to drive seamless system integration and rapid development cycles.

Required Qualifications

  • 10+ years of experience in systems engineering for aerospace, defense, or autonomous aircraft systems.
  • Demonstrated experience defining system behavior logic and operational modes.
  • Deep expertise in system architecture, avionics integration, and autonomy-driven flight systems.
  • Proficiency in MBSE, DOORS, SysML, CAMEO, or similar system modeling tools for complex systems design and analysis.
  • Experience with Group 4 or Group 5 UAS, military aircraft, or autonomous airborne platforms.
  • Strong background in flight testing, system integration, and performance validation.
  • Knowledge of DoD acquisition processes, MIL-STDs, FAA airworthiness certification, and airborne system safety standards.
  • Demonstrated ability to lead cross-functional teams and drive complex projects to successful completion.
  • Ability to work in a fast-paced, agile development environment with shifting priorities.
  • Worked on developmental program from clean sheet to first flight.

Preferred Qualifications

  • Experience developing AI-driven autonomy for unmanned aircraft.
  • Expertise in ISR, EW, and advanced sensor integration for airborne platforms.
  • Familiarity with modular open system architectures (MOSA) and Government Reference Architectures (GRA) for defense applications.
  • Prior experience working with defense primes, DoD stakeholders, or government R&D programs.
  • Active Secret or Top Secret clearance (or ability to obtain one).
