Job Description

As a Controls Engineer, you’ll help shape the way a revolutionary new class of vehicle moves. You’ll contribute to the development of the seaglider’s flight-control logic - ensuring it remains stable, responsive, and safe as it seamlessly transitions from displacement to hydrofoil to wing-in-ground-effect flight.

Job Responsibility

  • Own vehicle control laws: Design and implement control laws for stabilization, mode transitions, envelope protection, and emergency fallbacks
  • Apply safety-critical rigor: Define and trace requirements, lead design/code reviews, and develop rigorous test plans including SIL and HIL
  • Simulate, analyze, refine: Use and extend high-fidelity simulation environments to design and validate GNC algorithms
  • Integrate multisensor navigation: Develop and optimize state estimation algorithms that integrate GNSS/INS, radar altimeter, and other sensor inputs
  • Tune with real-world data: Leverage flight test and sea trial data to iteratively refine control algorithms
  • Collaborate across disciplines: Work closely with aero, hydro, mechanical, and systems teams
  • Lead test events: Plan, execute, and analyze full-scale test events to validate and mature flight controls

Requirements

  • Proven track record of designing and flight-testing control systems for aircraft, UAS, or similarly complex vehicles
  • Strong theoretical foundation in control theory, plus hands-on application to real systems
  • Proven design of real-world control systems and state-estimation filters
  • Experience designing control algorithms and simulations in MATLAB/Simulink
  • Demonstrated safety & quality mindset in regulated or mission-critical programs

Nice to have

  • Direct contribution to ARP4754A, DO-178C, or DO-254 certification artifacts
  • CFD-coupled control design or ground-effect / hydrofoil dynamics experience
  • Flight-test or sea-trial planning and execution

What we offer

  • Competitive compensation including a robust equity incentive plan
  • Comprehensive health, dental, and vision insurance - we cover 100% of your premiums
  • 401(k) with company matching
  • Generous flexible time off, paid parental leave, and company-wide holiday breaks
  • Relocation packages available
  • Daily, free catered lunches
  • Learning & professional development opportunities
