You will be able to demonstrate your technical skill, ability to be a team player and ability to deliver in accordance with the various drivers associated with commercial organisations.\nGNC systems for Astroscale missions require both standard and bespoke GNC & Computer vision algorithms and hardware, which need to be integrated together and with the wider satellite bus. This is often cutting edge, very complex, innovative and forms some of Astroscale’s most important intellectual property. This role will allow the right candidate to shape solutions for our missions.\nResponsibilities \nContribute development of GNC systems (requirements, FDIR, V&V strategy etc.) for Astroscale projects, ensuring integration of GNC algorithms, Computer Vision algorithms and GNC Hardware for RPO (Rendezvous and Proximity Operations) missions.\nContribute to the logical integration of the technical GNC subsystem work packages and overall solution, including the subsystem development and verification plans.\nCollaborate with other engineering disciplines in the planning, design and development of AS mission/system to ensure required GNC subsystem performance and compatibility.\nConduct state-of-the-art research into GNC (hardware and algorithm) designs relevant to Astroscale’s missions and perform subsystem level design and trade-off analysis.\nSupport GNC algorithm development and GNC hardware selection and integration for Rendezvous and Proximity Operation (RPO) missions.\nSupport development of GNC software architecture, with designs leading towards an overall GNC software solution.\nLiaise with customers and/or suppliers to characterize GNC system constraints/requirements, identify and/or present the technical GNC solution.\nProvide support to mission’s technical and programmatic leadership.\nProvide support and analysis for on-orbit operations of AS spacecraft.\nEssential Skills\nMaster’s degree in aerospace engineering or another relevant engineering/science discipline.\n2+ years’ relevant experience in a GNC related field\nMatlab/Simulink development skills - at least intermediate level.\nKnowledge and experience on the development of the GNC subsystem architecture\nHands on experience with at least 3 of the following:GNC requirement derivation and verification\nDesign and implementation of control laws and navigation algorithms.\nTheoretical knowledge of guidance strategies for RPO missions.\nTranslating algorithms into operational flight software.\nGNC hardware integration and test\nKnowledge of state-of-the-art GNC technologies/hardware used in space missions (technologies, trade-offs, procurement, data processing etc)\nKnowledge of various capture systems used for RPO missions\n\nDesirable skills\nExperience with implementation of RPO and docking algorithms/solutions.\nExperience with working with flight dynamics and a good level of understanding of relative orbital dynamics.\nOn-orbit operational experience of satellite missions.\nC/C++ software development skills - intermediate level.\nEmbedded software development skills - intermediate level.\nKnowledge of active debris removal missions e.g. RemoveDebris, e.DeOrbit, ATV, ELSA-d, CleanSpace, etc.\nBenefits\nCompetitive base salary\nOpportunity to work with a highly talented, diverse & dynamic international team with cutting edge technology\nFlexible working around core hours in a friendly and supportive environment\nOptional 9/75 working pattern\nHybrid working available (dependent on individual role requirements)\n25 days holiday (increasing yearly up to a maximum of 28 days) + 8 days Bank Holiday\nLife insurance and long-term sick pay\nPrivate healthcare (taxable benefit)\nRelocation allowance\nVisa sponsorship for employees considered\nState of the art office and cleanroom facility\nRegular social events \nLocation\nAstroscale UK (Harwell).\nAbout Astroscale\nFounded in 2013, Astroscale is the global leader in on-orbit servicing, dedicated to the secure and sustainable development of space for the benefit of future generations. We provide trusted and value-added solutions for government and commercial clients from their geography of choice, to drive the long-term, circular space economy. Astroscale is also collaborating with government and commercial stakeholders to develop norms, regulations, and incentives that promote the sustainable growth of space.\nSince our first successful launch in March 2021, Astroscale has proven rendezvous and proximity operations technologies in orbit during the ELSA-d and ADRAS-J missions, establishing the company as a leader in on-orbit servicing. 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 OneWeb. As more satellite operators adopt on-orbit servicing to routinely inspect, service and remove, the potential of a circular space economy - and a future of no waste in space - is being unlocked.\nAt Astroscale we pride ourselves on our inclusive culture. Our essential criteria are based solely on the requirements necessary to perform the role. If any criteria could present a barrier, we are open to discussing reasonable adjustments and are committed to ensuring an inclusive recruitment process. Astrsocale is also open to supporting job share arrangements, to further our flexible working offering.\nNote to recruitment agencies: Astroscale operates a preferred Supplier List, and we do not accept unsolicited agency approaches. Please do not forward candidate CVs or details in response to this advert, or to any Astroscale employee.","description_format":"text","description_chars":5796,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":["Flexible schedule","Hybrid work","Life insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Space Services"],"lifecycle":[{"event":"open","at":"2026-10-21T19:58:45Z"}],"visa":[],"liveness":{"score":24,"band":"cold","label":"Long shot","p_open":1,"p_active":0.554,"p_room":0.44,"age_days":71,"expected_fill_days":50,"reasons":["conf:4","velocity","win:tail","crowd:"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/astroscale-guidance-navigation-and-control-gnc-systems-engineer","json_url":"https://alion.io/job/astroscale-guidance-navigation-and-control-gnc-systems-engineer.json","meta":{"generated_at":"2026-10-28T06:23:54Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":8414,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":9484},"rest":"https://alion.io/mcp/rest/get_company?id=9484"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fastroscale-guidance-navigation-and-control-gnc-systems-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fastroscale-guidance-navigation-and-control-gnc-systems-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fastroscale-guidance-navigation-and-control-gnc-systems-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/astroscale-guidance-navigation-and-control-gnc-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fastroscale-guidance-navigation-and-control-gnc-systems-engineer"}]}
