Where dreams and reality collide and the output is, out of this world.
At Redwire Space, we are a team of dreamers and doers. Where the impossible becomes possible, and every day is an opportunity to learn and get one step closer to knowing the unknown. Join us on our mission to expand humanity’s presence in space.
Our team in Marlborough, MA has been actively accelerating humanity’s expansion into space for multiple decades. During that time, our innovative team has been designing and manufacturing mission-critical, high reliability optical sensors for satellites providing guidance, navigation, situational awareness, and control capabilities. With many more exciting projects on the horizon, our team could use your curiosity, passion, talent and experience to help us Build Above.
Summary
Redwire Defense Technologies has an opportunity for a Guidance, Navigation, and Control (GNC) Sensors Engineer to join the Optics and Algorithms team at our Marlborough, MA facility. The GNC Sensors Engineer is a multifaceted role in the engineering team working to support design, analysis, and support of GNC subsystems on various space programs including star trackers, sun sensors, and terrain relative navigation. This role includes working at the interface of electronics, software, and optics to develop high performing algorithms that are used satellite and spacecraft navigation. In this role, you will directly interface with customers to present and defend our GNC solutions and their performance in meeting the mission requirements.
Responsibilities
- Perform analysis to support early design phase concept development including sensor selection, predicted performance assessment
- Work closely with senior subject-matter expert for sun sensors to gain deep technical knowledge and progressively take on ownership of the subsystem.
- Perform sensor modeling, characterization, and performance analysis, including noise modeling, error propagation, and environmental sensitivity.
- Support sensor selection and trade studies, evaluating performance, cost, SWaP, and integration constraints.
- Analyze flight or test data to evaluate system performance, identify anomalies, and recommend improvements.
- Work with cross-functional teams to integrate sensors and algorithms into broader GNC subsystems.
- Collaborate with hardware, systems, and software engineers to ensure end-to-end system reliability and robust sensor behavior in operational environments.
- Document designs, analyses, and test results in clear technical reports, presentations, and customer-facing materials.
