As a GNC/AOCS Engineer at Spire, you will operate as part of a technical team that maintains responsibility across the full lifecycle of its engineering products. 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:
- Technical ownership of current and future spacecraft attitude and orbit control software and hardware.
- Design, model, analyze, integrate and operate attitude determination/estimation systems for small spacecraft.
- Develop and utilize spacecraft dynamics and control simulations, including "hardware‑in‑the‑loop".
- Design, evaluate, select, qualify and implement flight sensors, including magnetometers, sun sensors, inertial measurement devices, infrared sensors, and/or star trackers.
- Design, evaluate, select, qualify and implement flight actuators, including magnetic torque elements, reaction wheels, and propulsion systems.
- Be hands‑on in laboratory and manufacturing environments during testing, integration, and qualification of flight systems.
- Provide support and analysis for on‑orbit operations of spacecraft attitude determination and control systems.
- Work with external contractors, manufacturers, and internal manufacturing staff to improve reliability, yield, performance, and cost of flight systems.
Key Skills:
- Extensive experience with a solid foundation in spacecraft attitude dynamics and control algorithms, with emphasis on practical application of knowledge.
- Experience designing and/or implementing Kalman filters for attitude estimation.
- Experience with flight sensors for spacecraft attitude determination/estimation.
- Familiarity with the Linux development environment.
- Experience working with external engineering contractors.
Preferred Skills:
- Experience writing flight software.
- 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.
We are proud to be an equal‑opportunity employer and are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, marital status, disability, gender identity or veteran status.
To help maintain a safe and secure workplace for Spire employees, all candidates who receive a conditional offer will be required to complete a background check. This may include criminal history and employment verification.
