GNC Engineer (M/F)

Astroscale France is looking for an experienced GNC Engineer to support the growth of our Toulouse office.

GNC subsystems for Astroscale missions require both standard and bespoke GNC algorithms and hardware equipment. The algorithms are often cutting edge, very complex, innovative and form some of Astroscale’s most important intellectual property. These, along with the hardware, must be integrated to form an integration, high-performing subsystem. Given the technical complexity and importance to Astroscale of this subsystem, a team of GNC engineers is required to take responsibility for this aspect of the GNC Group’s work.

Your responsibilities

⚙️ Algorithms

Contribute to GNC algorithm development – analyse, design, implement and validate algorithms for RPO (Rendezvous and Proximity Operations), working other engineering disciplines (especially flight dynamics, flight software) to develop safe GNC algorithm solutions which meet Astroscale’s project requirements (inc. technical and programmatic).

Ensure configuration management and technical integrity of GNC algorithms throughout the development lifecycle.

Support the definition and evolution of the GNC software architecture, ensuring consistency with the overall spacecraft and software system architecture.

About Astroscale

Astroscale is the global leader in on-orbit servicing, dedicated to the secure and sustainable development of space. The company delivers a variety of innovative and scalable on-orbit servicing solutions, including life extension, refurbishment, upgrades, in-situ space situational awareness, end-of-life, and active debris removal. Since its first successful launch in March 2021, Astroscale has proven rendezvous and proximity operations technologies in orbit during the ELSA-d and ADRAS-J missions. Astroscale spacecraft have been selected for pioneering missions with JAXA, the U.S. Space Force, the European Space Agency, the UK Space Agency, and Eutelsat. As more satellite operators adopt on-orbit servicing to routinely inspect, relocate, remove, and extend the life of spacecraft, the potential of a circular space economy — and a future of no waste in space — is being unlocked. Headquartered in Japan, Astroscale has a global presence with subsidiaries in the United Kingdom, the United States, France, and Israel. Find out more about Astroscale at www.astroscale.com
