We combine hardware and software into a plug-and-play platform for developers, researchers and enterprises, with an open ecosystem that supports the development of physical AI.\nThe Role\nWe are looking for a hands-on mechanical or mechatronics engineer to own the architecture of integrated actuators for Dexmate robots. You will translate robot requirements into an actuator design that balances torque, speed, mass, efficiency, backdrivability, thermal capacity and manufacturability. You will make technical trade-offs, build and test hardware, and bring specialists together around a verified design.\nResponsibilities\nDefine actuator requirements from robot loads and duty cycles, including peak and continuous torque, speed, stiffness, life, packaging and thermal limits.\n\nOwn trade studies across motor topology, transmission ratio, bearings, cooling, sensing and drive constraints; use measured performance to resolve competing requirements.\n\nSet mechanical, electrical and firmware interfaces, including voltage and current limits, sensor placement, allowable temperatures and fault responses.\n\nLead prototype builds and hands-on debugging. Maintain direct ownership of CAD and analysis reviews, bench debugging and technical decisions.\n\nDevelop characterization plans with motor, drive, controls and test engineers; correlate torque-speed, efficiency, thermal, friction and backdrivability results to models.\n\nDrive design reviews, supplier decisions, DFM and corrective actions through production release, with clear requirements and acceptance criteria.\n\nMinimum Qualifications\nDelivered an integrated actuator, servo or electromechanical drive into a production or deployed product, with direct ownership of architecture and hardware decisions.\n\nStrong depth in mechanical or mechatronic design and working understanding of motors, transmissions, thermal behavior, sensors and drive limitations.\n\nAbility to quantify system trade-offs and explain how analysis, bench data and failure investigation changed a design.\n\nHands-on experience with prototyping, validation, supplier collaboration and manufacturing release; ability to lead across engineering disciplines.\n\nPreferred Qualifications\nExperience in robot joints, industrial drives, EV drive units or aerospace electromechanical actuators.\n\nExperience with high torque-density or backdrivable actuators and compact liquid-cooled assemblies.\n\nTechnical mentorship and ownership of a subsystem roadmap without losing direct design and test involvement.","description_format":"text","description_chars":2640,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotic Components & Sensors","Robotics AI","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-11-07T00:09:28Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 13","filings_12m":13,"filings_prev_12m":1,"green_card_filings_12m":0,"median_offered_wage_usd":132500,"route":null,"cap_exempt":false,"checked_at":"2026-11-08T10:45:15+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":155,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-11-08T05:47:12Z"},"pay":null,"html_url":"https://alion.io/job/dexmate-mechanical-design-engineer-for-actuator-integration","json_url":"https://alion.io/job/dexmate-mechanical-design-engineer-for-actuator-integration.json","meta":{"generated_at":"2026-11-09T03:35:55Z","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":1949,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":6958},"rest":"https://alion.io/mcp/rest/get_company?id=6958"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdexmate-mechanical-design-engineer-for-actuator-integration"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fdexmate-mechanical-design-engineer-for-actuator-integration"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fdexmate-mechanical-design-engineer-for-actuator-integration"},{"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/dexmate-mechanical-design-engineer-for-actuator-integration\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdexmate-mechanical-design-engineer-for-actuator-integration"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3899197}},{"tool":"search_jobs","arguments":{"company":"dexmate.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3899197},"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);
