including mechanical, propulsion, electronics, and mission planning - to ensure reliable thermal performance of our satellite throughout all mission phases: from launch to operation in orbit and end-of-life.\nYou should be capable of delivering a thermal control system from scratch and taking full ownership of it, ensuring the success of our mission.\nKey Responsibilities\nPerform steady-state and transient thermal analysis of the spacecraft across all mission phases (TVAC testing, launch, orbit).\n\nModel and validate heat management strategies in the harsh environment of vacuum, where conduction and radiation are dominant\n\nIdentify and manage worst-case scenarios in extreme thermal conditions (both hot and cold), accounting for on-orbit environmental factors and internal power dissipation\n\nDesign and implement thermal control solutions such as multilayer insulation (MLI), radiators, heaters, thermo-optical coatings, thermistors, and thermal straps\n\nDevelop and support thermal vacuum (TVAC) test procedures, instrumentation setup, and post-test data analysis.\n\nBe hands on in hardware testing for validation of processes, instrumentation, and materials and components chosen for in house developments\n\nFundamental Requirements\nSolid understanding of thermal engineering principles in the context of spacecraft systems.\n\nHands-on experience with thermal simulation tools such as Systema, Thermal Desktop, ESATAN, or equivalent.\n\nExperience with environmental and lab testing (TVAC, thermal cycling, AIT process validation).\n\nComfortable working in a fast-paced, iterative development environment.\n\nNice-to-Haves\nExperience designing or testing spacecraft thermal systems.\n\nExposure to multidisciplinary space system development or mission analysis.\n\nWhy NewOrbit Space?\nPioneering space technology - Your work on our RF gridded ion thrusters and VLEO satellite platform will redefine satellite operations and challenge traditional LEO.\n\nOwnership and impact - You'll have a level of ownership that's rare in the space industry, and you'll take part in the full lifecycle of satellite technology.\n\nEquity and competitive salary - Alongside a competitive salary you receive a company ownership stake, so you share in the technology you help build and in our collective success.\n\nComprehensive benefits - Private health insurance with dental and optical cover, and annual health check-ups.\n\nHybrid working - One dedicated remote day per week.\n\nVisa sponsorship and relocation support - We sponsor visas and provide relocation support for candidates moving to join us.","description_format":"text","description_chars":3369,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Health insurance","Hybrid work"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Earth Observation"],"lifecycle":[{"event":"open","at":"2026-11-04T18:43:43Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"adverts_offering_sponsorship_24m":9,"sanctioned_now":false,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-11-07T06:20:45+00:00","sources":["UK Home Office: register of licensed sponsors (workers)","Alion: sponsorship offered in the employer's own job adverts (24 months)"],"filings_for_role_12m":0}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":55,"reasons":["conf:2","win:early"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/neworbit-thermal-engineer","json_url":"https://alion.io/job/neworbit-thermal-engineer.json","meta":{"generated_at":"2026-11-07T07:10:56Z","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":1934,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":679537},"rest":"https://alion.io/mcp/rest/get_company?id=679537"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fneworbit-thermal-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%2Fneworbit-thermal-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%2Fneworbit-thermal-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/neworbit-thermal-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fneworbit-thermal-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3761533}},{"tool":"search_jobs","arguments":{"company":"neworbit.space","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3761533},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
