• Integrate GNC and Computer Vision algorithms into real-time onboard software, ensuring deterministic execution and system-level consistency.

• Contribute to and influence the onboard softwarearchitecture and hardware-softwarepartitioning.

• Implement robust fault detection, isolation, and recovery (FDIR) mechanisms.

• Develop and execute Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) test campaigns in support of mission validation.

Wider responsibilities

• Liaise with GNC and Computer Visionteams to integrate their work on theFlight Software.

• Support coordination of Flight Software activities across subsystem teams to ensure coherent system integration.

• Attend and support reviews with potential partners or clients.

• Support knowledge transfer acrossAstroscale teams globally.

Expected results

• Deliver Flight Softwarethat meets mission performance, safety, and reliability requirements.

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.
