That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND-01 - our rapidly developed humanoid platform being deployed in real industrial environments - and we’re growing the team to take it even further.\nAbout The Role\nAs a Senior Mechanical Design Engineer on the Core Platform team, you’ll play a key part in turning ambitious, open-ended ideas into high-performing, real-world robotics solutions. Your work will span hands-on design, collaborative prototyping, and technical validation, driving innovation in mechanisms, and structures. You’ll develop detailed CAD models and documentation, ensure manufacturability and safety, and work closely with cross-disciplinary teams and vendors-all while adapting to rapidly evolving project needs. This is an opportunity for creative engineers who thrive on solving complex problems and shaping the future of robotic design.\nWhat You’ll Do\nInterpret Open-Ended Design Requirements: Help transform broad project requirements into detailed, pragmatic design specifications for new systems and components.\n\nCollaborate Across Disciplines: Work with engineers from various disciplines to brainstorm, design, and develop prototype robots that meet challenging performance targets.\n\nInnovate with Mechanisms and Structures: Design and refine innovative mechanisms, interfaces, and structures that elevate robot performance, from energy-absorbing crash protection to ergonomic robot coverings.\n\nCAD Design & Documentation: Create and manage CAD models, engineering drawings, assembly documentation, and test plans for parts and assemblies.\n\nAnalysis and Validation: Perform necessary analyses on new designs, validate them through bench tests, and ensure that they meet all performance, safety, and manufacturability standards.\n\nTroubleshoot and Implement Solutions: Identify and resolve design issues by determining root causes and implementing effective corrective and preventative measures.\n\nVendor Management: Collaborate with external vendors for components and assemblies that require outsourcing, ensuring that third-party designs meet Humanoid’s stringent requirements.\n\nAdapt to Changing Needs: Stay flexible and responsive to changing project requirements while maintaining a team-first, collaborative mindset.\n\nWhat We're Looking For\nBSME with 5+ years of relevant experience\n\nExperience designing high-performance mechanical structures, motion mechanisms, and integrated systems, ideally in robotics or comparable high-precision fields.\n\nAdvanced proficiency in CAD software (NX, SolidWorks, Creo etc.) with experience in FEA and topology optimization. We use Solidworks.\n\nStrong understanding of ASME drafting standards, including GD&T (Y14.5-2018).\n\nExperience transitioning designs from early concepts (NPI, EVT, DVT) to production.\n\nFamiliarity with production processes such as casting, sheet metal, stamping, hydroforming, composites, and compliant energy-absorbing structures.\n\nExperience designing lightweight, high-performance structures, compliant mechanisms, and flexible energy-absorbing designs.\n\nCreative and collaborative thinking with a team-first mentality.\n\nWhat We Offer\nComprehensive health coverage for US-based employees, including fully paid medical, dental, and vision insurance, with virtual care and employee assistance resources.\n\nMeaningful time off to rest and recharge: 23 days of PTO (accrued), separate sick leave, and paid company holidays.\n\n401(k) retirement plan with a 4% employer match.\n\nEquity included-we believe builders should share in what they build.\n\nFree daily catered lunch, snacks, and drinks in-office.\n\nCollaboration with top-tier engineers, researchers, and product experts in AI and robotics.\n\nFreedom to influence the product and own key initiatives.\n\nFor this role in Massachusetts, the expected base salary range is $160K-$215K USD per year; your placement in that range depends on how your experience maps to our internal leveling.","description_format":"text","description_chars":4126,"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":["Equity","Retirement plans","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Logistics & Warehouse Robotics","Industrial Robotics","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-04-17T16:30:54Z"}],"visa":[],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.431,"p_room":0.28,"age_days":182,"expected_fill_days":58,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/humanoid-senior-mechanical-design-engineer","json_url":"https://alion.io/job/humanoid-senior-mechanical-design-engineer.json","meta":{"generated_at":"2026-10-17T22:04:08Z","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":7057,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":35230},"rest":"https://alion.io/mcp/rest/get_company?id=35230"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhumanoid-senior-mechanical-design-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%2Fhumanoid-senior-mechanical-design-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%2Fhumanoid-senior-mechanical-design-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/humanoid-senior-mechanical-design-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhumanoid-senior-mechanical-design-engineer"}]}
