Founding Lead GNC Engineer

About the role

We are seeking a Lead Founding GNC Engineer to own guidance, navigation, and control from first principles for autonomous spacecraft, across rendezvous, proximity operations, and related autonomous flight operations. This is a senior technical leadership role.

Responsibilities

• Own the GNC architecture for autonomous rendezvous, proximity operations, and related mission phases, from early design through simulation, testing, integration, and flight.
• Lead the development of guidance, navigation, and control algorithms for approach, stationkeeping, proximity maneuvers, aborts, collision avoidance, and other safety-critical maneuvers.
• Design and analyze trajectories for orbital operations and other relevant flight regimes, including mission trades, dispersions, constraints, and operational margins.
• Provide technical leadership across GNC, autonomy, simulation, test, and flight software efforts.
• Help hire, manage, mentor, and develop GNC, controls, autonomy, simulation, and related engineers as the team grows.
• Establish engineering processes, review standards, technical decision-making norms, and verification discipline appropriate for flight-grade systems.
• Build relative navigation and state-estimation systems using sensors such as vision, LiDAR, radar, IMUs, GNSS, star trackers, and other flight-relevant hardware.
• Develop high-fidelity simulation, Monte Carlo, hardware-in-the-loop, and processor-in-the-loop test environments to validate GNC performance and robustness.
• Help define requirements, interfaces, error budgets, verification plans, and fault-handling approaches for the GNC subsystem and broader vehicle.
• Select, integrate, and test GNC-relevant hardware, including sensors, actuators, processors, and representative test equipment, working with vendors and internal teams as needed.
• Develop and test flight GNC software in close collaboration with flight software, avionics, autonomy, propulsion, mechanical, and mission operations teams.
• Contribute to system-level trades across algorithms, sensors, hardware, software, schedule, cost, reliability, and mission risk.
• Work closely with the founders and early engineering team to shape the technical roadmap, engineering culture, hiring plan, and long-term GNC strategy.
• Represent the GNC function in cross-disciplinary design reviews, customer conversations, investor diligence, vendor discussions, and mission planning as needed.

Requirements

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Robotics, Controls, Computer Science, or a related technical discipline.
• 8+ years of experience designing, simulating, implementing, testing, or flight-qualifying GNC algorithms for spacecraft, launch vehicles, hypersonic/reentry systems, autonomous aircraft, robotics, or other high-reliability autonomous systems.
• Prior experience leading technical workstreams, managing engineers, mentoring junior and mid-level engineers, or building high-performing engineering teams.
• Demonstrated ability to own complex technical systems from early architecture through implementation, test, validation, and operational readiness.
• Strong fundamentals in orbital mechanics, control theory, estimation, dynamics, linear algebra, numerical methods, and sensor fusion.
• Experience with GNC simulation, including 6-DOF dynamics, closed-loop simulation, Monte Carlo analysis, dispersions, and off-nominal testing.
• Proficiency in MATLAB/Simulink and at least one production language such as C, C++, Python, or Rust.
• Experience taking algorithms beyond analysis and into real implementation, hardware testing, flight software, embedded systems, hardware-in-the-loop, processor-in-the-loop, or representative testbeds.
• Ability to work independently with limited direction, identify the right next problem to solve, and drive technical work from ambiguity to tested hardware or software.
• Ability to make practical system-level tradeoffs across performance, schedule, cost, reliability, testability, and mission risk.
• Ability to lead through influence in a cross-functional environment spanning flight software, avionics, autonomy, propulsion, mechanical, systems, and mission operations.

Qualifications

• Direct experience with spacecraft rendezvous, proximity operations, or autonomous capture.
• Experience leading GNC, autonomy, controls, simulation, flight software, or mission design teams.
• Experience managing engineers in a startup, aerospace company, defense contractor, launch company, robotics company, or other high-reliability technical environment.
• Experience setting technical direction, conducting design reviews, making architecture decisions, and holding teams accountable to execution milestones.
• Experience with advanced flight regimes such as atmospheric reentry, entry/descent guidance, hypersonic flight, aerodynamics, or aerothermal constraints.
• Experience defining trajectories for proximity operations, inspection, servicing, stationkeeping, or other constrained autonomous spaceflight operations.
• Experience with optical navigation, LiDAR navigation, radar navigation, or multi-sensor relative navigation against cooperative or non-cooperative targets.
• Experience integrating radar into an autonomy or GNC sensing chain, including measurement modeling, tracking, calibration, filtering, and failure modes.
• Experience with AI for GNC, AI-assisted autonomy, learned perception, learned dynamics models, reinforcement learning for control, AI-based sensor processing, onboard autonomy, or AI-enabled fault detection.
• Experience selecting, purchasing, integrating, and testing GNC hardware, including sensors, actuators, processors, cameras, LiDAR, radar, IMUs, GNSS, star trackers, reaction wheels, or propulsion components.
• Experience working with vendors, evaluating datasheets, performing make-buy decisions, navigating supply chain issues, and qualifying hardware for flight or other high-reliability environments.
• Experience designing test infrastructure for hardware developed internally, including calibration rigs, dynamics testbeds, flat-sats, air-bearing tables, sensor test setups, HIL/PIL rigs, and integrated avionics test campaigns.
• Experience with formal requirements, V&V, flight qualification, mission assurance, fault trees, hazard analysis, or safety-critical software.
• Experience with STK, GMAT, Basilisk, Trick, Monte, FreeFlyer, custom mission analysis tools, or comparable simulation and trajectory design environments.
• Experience transitioning GNC from prototype through flight operations, anomaly response, post-flight reconstruction, and design iteration.
• Experience in early-stage startups, small high-performing teams, or environments where engineers must own broad technical scope.
• Experience recruiting, interviewing, closing, and onboarding exceptional technical talent.
