GNC Engineer

As a GNC/AOCS Engineer at Spire, you will operate as part of a technical team who maintains responsibility across the full lifecycle of the Spire GNC product and its subcomponents. The GNC team interfaces directly with many engineering groups to conduct R&D, design, manufacturing, and operations activities, ultimately ensuring all current and future spacecraft systems satisfy their mission. Ideal candidates will embrace the commercialization of nanosatellite systems and adapt to low-cost, fast-paced systems design, development, and implementation methodologies that set Spire apart from our competition. In this fast-paced environment, the design to launch cycle is measured in weeks and months, not years. What You’ll Do: • Design, evaluate, select, qualify and implement flight sensors, including magnetometers, sun sensors, inertial measurement devices, Earth sensors, and/or star trackers. • Design, evaluate, select, qualify and implement flight actuators, including magnetic torque elements, reaction wheels, and propulsion systems. • Design, implement and maintain simulation models for GNC subcomponents in our 6-DOF simulation environment. • Technical ownership of current and future GNC avionics peripherals, supporting troubleshooting, design and updates to improve reliability and performance. • Working closely with cross-functional teams, including hardware, software, and systems engineers, to integrate avionics solutions into the larger platform. • Develop component qualification and acceptance processes and be hands-on in laboratory and manufacturing environments. Key Skills: • Experience with flight sensors for spacecraft attitude determination/estimation. • Experience with actuators, including actuator sizing, modelling, design and integration. • A solid foundation in spacecraft attitude dynamics and control algorithms, with emphasis sensor ingestions and actuator command calculation. • Experience working hands-on with HW and familiarity with 'hardware-in-the-loop` simulation. • Experience developing software using C/Python. • Have experience or familiarity with the Linux development environment. • Have experience working with external engineering contractors. Preferred Skills: • Experience writing flight software. • Experience designing and/or implementing Kalman filters and feedback control for attitude estimation. • Experience with C or C++ development for embedded systems. • Experience with spacecraft design. • Experience with spacecraft assembly, integration, and testing. • Experience with spacecraft operations and maintenance. • Experience identifying and resolving system anomalies. • Experience creating and maintaining integration and test campaigns for attitude determination and control systems, including hardware and software. Spire operates a hybrid work model, and this position will require you to work a minimum of three days per week in the office. Access to US export-controlled software and/or technology may be required for this role. If needed, Spire will arrange the necessary licenses—this is not something candidates need to have before applying. . #LI-MI Global Perks 🛰️ Name Your Satellite Program (NYSP) 🚀 Launch Attendance 🌴 Generous Time Off Policy 🎓 Education Assistance Program 🥰 Employee Assistance Program (EAP) 📈 Employee Stock Purchase Program (ESPP) 👣 Family Leave 💪 Fitness Reimbursement 🧡 Employee Referral Program 🍉 Healthy snacks & beverages in every office About Spire We improve life on Earth with data from space.
