Description

What You'll Be Doing

  • Provide technical leadership for the design, development, and integration of GN&C algorithms and flight control software.
  • Develop Simulink models to support flight controls development, vehicle dynamics, and linear/non‑linear simulation analysis.
  • Lead and coordinate multi‑disciplinary engineering teams throughout the lifecycle of air vehicle development.
  • Architect inner‑ and outer‑loop control laws and create advanced control algorithms for both crewed and uncrewed aircraft.
  • Oversee end‑to‑end simulation campaigns, validation testing, and Hardware‑in‑the‑Loop (HIL) test activities.
  • Serve as a subject matter expert in design reviews, program milestones, and technical discussions with leadership and customers.
  • Develop and implement GN&C best practices, standards, and processes across the engineering organization.
  • Generate clear, comprehensive reports documenting simulation results, test outcomes, trade studies, and alternatives analyses.
  • Build strong relationships with clients, suppliers, and industry partners to drive collaboration and technical excellence.
  • Identify opportunities for innovation, optimization, and continuous improvement across algorithms, models, and workflows.

Must‑Have Qualifications

  • Bachelor's degree in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, or related field.
  • Typically 10+ years of relevant GN&C, flight controls, simulation, or aerospace engineering experience. Higher‑level degrees may substitute for experience.

  • Advanced experience with Computer‑Aided Engineering tools, analysis, and simulation environments.
  • Proficiency with MATLAB/Simulink for model development, control law design, and simulation analysis.
  • Experience working within multi‑disciplinary design and development teams.
  • Ability to obtain and maintain a Secret U.S. Security Clearance.

Preferred Qualifications

  • Master's degree or Ph.D. in Aerospace Engineering or a related field.
  • Experience with system modeling tools such as MATLAB/Simulink, STK, or FreeFlyer.
  • Background designing flight control laws for unmanned or optionally piloted aircraft systems.
  • Knowledge of MIL‑STD‑1797B (Flying Qualities of Piloted Aircraft).
  • Experience performing HIL testing of integrated flight control systems.
  • Prior support of aircraft flight testing or vehicle performance evaluations.
  • Experience with aerospace vehicles, sensor suites, actuation systems, and mission‑level GN&C.
  • Familiarity with model‑based definition, parametric design, and orbital or flight mechanics.
  • Demonstrated success leading baseline definition, integrated trade studies, and maturation of complex systems.
  • Professional background in the Aerospace & Defense industry.

Why You'll Love Working Here

  • 3 weeks paid time off, flex‑time options, and development opportunities.
  • Leadership training, mentorship programs, and education reimbursement.
  • Exclusive company events and a supportive team culture.
  • Modern, collaborative campus environments (location specific)
    • On‑site fitness centers.
    • State‑of‑the‑art coffee bars.
    • Full‑service cafeterias with planned breakfast and lunch.
    • Access to scenic walking and biking trails.
