Senior Optical Navigation Responsible Engineer (Lunar)

As the Senior Optical Navigation (OpNav) Responsible Engineer at Impulse Space, you will own the terrain-relative navigation (TRN) system that brings our lunar lander from low lunar orbit to a precise, safe touchdown. You will be the single technical owner and product owner for TRN: you'll set the requirements, architecture, development roadmap and verification strategy, and you'll pace the program so the capability is ready when the vehicle is. You will work closely with GNC, flight software, avionics, mission design, and test to turn a lunar landing mission into a navigation system that is defined, built, verified, and flown. Own the TRN system end to end: concept of operations, requirements, architecture, and the interfaces Turn mission and landing needs into flowed-down navigation requirements and error budgets As product owner for TRN: maintain the technical roadmap, prioritized backlog, and development milestones, aligning with lander integration, test, and mission schedules Coordinate across multiple teams to achieve system-level success Lead make/buy and sensor trades for descent navigation: cameras, compute, and more Define the onboard map and reference-data pipeline Lead and define the TRN verification strategy across analysis, synthetic-image simulation, software-in-the-loop (SIL) and hardware-in-the-loop (HIL) testing with image injection, Monte Carlo campaigns, and field or flight testing Define TRN fault detection, health monitoring, and fallback modes with GNC and autonomy Represent TRN in design reviews and risk reviews. Communicate status, trades, and risk to engineering and leadership Support integration, test campaigns, and mission operations through descent and landing Bachelor's degree in Aerospace Engineering, Electrical Engineering, Robotics, Computer Science, Physics, or a related discipline 8+ years of experience in spacecraft or aircraft navigation, optical/vision-based navigation, or GNC systems engineering Demonstrated experience defining requirements, interfaces, and error budgets for a navigation or sensing system Demonstrated work in verification, simulation, or test of navigation or perception systems Experience with flight- or development-hardware selection, procurement, or test Working knowledge of state estimation (e.g., Kalman filtering) and how measurement errors affect navigation performance Proficiency in Python and/or MATLAB; ability to read and review C++ flight code Excellent technical communication skills 10+ years of experience in spacecraft or aircraft navigation, optical/vision-based navigation, or GNC systems engineering Demonstrated experience with terrain-relative navigation, precision landing, or hazard detection Experience with landmark, crater, or map-relative localization and feature-tracking algorithms Experience with lunar or planetary map products and tools (e.g., Lunar Reconnaissance Orbiter imagery and digital elevation models) Experience with camera models, calibration, radiometry, and synthetic scene or image generation for testing and system validation Experience with descent sensors such as laser altimeters, Doppler lidar or velocimeters, and flash lidar Experience running field, or flight test campaigns for navigation sensors Product owner or technical lead experience pacing a team’s development effort, managing a backlog, or overseeing suppliers Experience with powered descent, entry-descent-landing, rendezvous and proximity operations, or other deep-space missions Experience in a startup or fast-paced, iterative hardware development environment Additional Information: Compensation bands are determined by role, level, location, and alignment with market data.
