A fast-growing space scale-up at the forefront of satellite innovation, specializing in advanced software-flexible satellites for commercial, governmental, and scientific endeavors.\n\nThis is more than a job, it’s a mission – We are making space universally accessible and redefining what’s possible.\n\nWe get things done – We take ownership of what we do and we work hard to make a difference.\n\nWe are fearless – Transparency is our only way forward. We dare to address and resolve issues head-on.\n\nWe learn from our mistakes – We deliver, take informed risks, and evolve to achieve our goals. We compare with the best version of ourselves\n\nWhat is the role?\n\nAs a Mechanical AIT Engineer, you turn engineering intent into flight-ready hardware with full traceability, reliability, and speed. You will be at the heart of our production floor, transforming engineering drawings into fully functional satellites\n\nSome of your daily tasks will include:\n\nBuild flight hardware: assemble and integrate structures, mechanisms, propulsion modules, payloads, and harnesses on our platforms per drawings, BOMs, and work instructions.\n\nOwn integration: perform precision torquing/locking, bonding and staking, adhesive/RTV application, connector mating, harness dressing, and cleanliness controls.\n\nGuard quality: execute incoming, in-process, and final inspections; enforce ESD/FOD and cleanroom protocols; ensure configuration control and full part traceability.\n\nDocument precisely: create and maintain travelers, detailed work instructions, torque logs, build records, and nonconformance reports (NCR/MRB).\n\nTest for flight: prepare MGSE/fixtures and support environmental test campaigns (vibration, shock, TVAC); run fit checks and post-test inspections; contribute to TRR/PRR/ATRs.\n\nProblem-solve fast: diagnose integration issues, drive root-cause analysis, and feed DFM/DFA improvements back to design.\n\nImprove continuously: implement 5S, lean practices, and data-driven improvements to reduce cycle time and increase first-pass yield.\n\nEnable the team: collaborate daily with design, electronics, RF, production, and test to deliver on schedule and to spec.\n\nWhat do we look for?\n\nDegree in Mechanical, Aerospace, or related engineering.\n\n5+ years of hands-on assembly/integration of high-reliability hardware (space, aerospace, defense, medical, or similar).\n\nStrong command of mechanical systems and good understanding of electrical interfaces; fluent in reading CAD, GD&T, and schematics.\n\nProven proficiency with precision tools (torque tools, calipers, micrometers) and workmanship to ECSS/IPC/NASA standards.\n\nExperience in cleanroom environments with strict ESD, FOD, and contamination control.\n\nExcellent troubleshooting, root-cause analysis, and clear technical documentation in English.\n\nHow to Stand Out:\n\nDirect AIT experience on nano/microsatellites or spacecraft subsystems.\n\nFamiliarity with ECSS/NASA workmanship standards and space-quality assurance.\n\nHands-on with environmental testing (TVAC, vibration, shock) and test procedure authoring.\n\nExperience with ERP/PLM/MES and digital travelers; JIRA/Confluence is a plus.\n\nLean/Six Sigma exposure; demonstrable continuous improvement results.\n\nExperience with propulsion integration, precision mechanisms, opto-mechanics, or harness assembly (IPC/WHMA-A-620).\n\nData skills for test analysis (e.g., Python/Matlab) are welcome.\n\nWhy EnduroSat?\n\nFast-paced and delivery-focused culture – We work with well-defined quarterly based objectives, that allow us to fast-track the progression of our work and improve as we go\n\nTough engineering challenges & hard-core R&D – You will be able to work on unique space technology and build next-gen innovations, while mentored by world-recognized space experts\n\nConstant learning and progression – Own your personal growth by navigating through our career progression framework and educational programs\n\nChance to join our space educational program – Meet international space experts and improve your knowledge and skillset with our hands-on educational program\n\nAt EnduroSat, we embrace diversity and strive to create an inclusive environment where everyone is treated with fairness and respect. We are committed to equal employment opportunities without discrimination against any employee or job applicant on the basis of race, color, religion, sex, national origin, age, disability, sexual orientation, or gender identity. Additionally, this position is suitable for people with disabilities in accordance with the People with Disabilities National Regulation Act, ensuring accessibility and accommodation in the workplace.","description_format":"text","description_chars":4657,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Space & Aerospace","Satellite Communications","Satellite Manufacturing"],"lifecycle":[{"event":"open","at":"2026-10-11T06:29:33Z"}],"visa":[],"liveness":{"score":61,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.793,"p_room":0.9,"age_days":14,"expected_fill_days":22,"reasons":["seen:14","win:mid"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/endurosat-mechanical-ait-engineer","json_url":"https://alion.io/job/endurosat-mechanical-ait-engineer.json","meta":{"generated_at":"2026-10-13T18:17:45Z","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":27936,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":55463},"rest":"https://alion.io/mcp/rest/get_company?id=55463"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fendurosat-mechanical-ait-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%2Fendurosat-mechanical-ait-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%2Fendurosat-mechanical-ait-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/endurosat-mechanical-ait-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fendurosat-mechanical-ait-engineer"}]}
