Founded in 2024 as an ETH Zurich spin-off, RIVR developed wheeled-legged robots designed to operate in complex, unstructured environments such as stairs, gates, doors, and uneven urban terrain. We believe that achieving general physical intelligence requires solving real customer problems in the real world, where robots can learn from rich operational data at scale.\nFollowing our acquisition by Amazon in March 2026, we are continuing this mission with greater reach and speed. By combining custom robot hardware, onboard autonomy, and cloud-based coordination, RIVR, part of Amazon is building the next generation of safe, reliable autonomous robots for last-mile delivery.\nJob Description\nWe are seeking an experienced Mechanical Engineer to own the complete mechanical architecture, physical packaging, and harness routing strategy for our power distribution boards and control systems. Unlike traditional heavy EV inverters, our platform demands a lightweight structural approach while managing electronics packaging issues. In this role, you will lead the clean-sheet design of electronic enclosures, thermal management, and the complete wiring harness. You will act as the bridge between mechanical and electrical engineering, ensuring our systems are robustly packaged, sealed, routed, and ready for high-volume manufacturing.\nWhat will you be doing\nOwn the design and development process of electronic enclosures for our power boards and computational units, from concept to mass production.\n\nResolve complex mechanical challenges includingelectrical isolation, environment sealing, thermal management, shock and vibration, electromagnetic interference, etc.\n\nRun required design analysis including thermal, CFD, structural (FEA), etc.\n\nDefine suite of test required to validate design together with testing team. Run root cause analysis and plan mitigations.\n\nCreate 2D drawings andsupporting documentation for smooth handoverto manufacturing team.\n\nGuarantee manufacturability of parts and assembly. Lead supplier talks throughDFM negotiations, run DFA analysis with manufacturing team.\n\nWhat You'll Bring\nBachelor’s or Master’s Degree in Mechanical Engineering, Mechatronics, or equivalent experience.\n\n6+ years of hands-on industry experience designing electro-mechanical assemblies, electronic enclosures, and wire harnesses for moving platforms.\n\nProficiency in CAD (Solidworks, Siemens NX, CATIA, etc.), experience with validation tools (e.g. Ansys, COMSOL, etc.). Knowledgeable with PLM systems\n\nRobust understanding of mechanical principles (heat transfer, structural design,material selection, fluids, GD&T, etc.)\n\nExperience on bringing prototypes to mass production using appropriate technologies like: die casting, injection molding, compression molding, thixomolding, progressive stamping, extrusion, etc.\n\nKnowledgeable of material science usedin electronic enclosures, gaskets and grommets.\n\nExperience developing Test plans.And running appropriate root case analysis.\n\nUnderstanding of electrical design, PCBa, components and it’smanufacturing process.\n\nGet Some Bonus Points\nExperience with harness design and routing. Collaboratingdirectly with Electrical engineeringteamto select and specify appropriate connectors,terminalsand wire gauges.\n\nGeneratewire harness2Ds, layouts and pinout tables for manufacturers.","description_format":"text","description_chars":3446,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Electrical & Electronic Engineering","Robotics AI","Logistics & Warehouse Robotics"],"lifecycle":[{"event":"open","at":"2026-09-07T18:28:46Z"}],"visa":[],"liveness":{"score":77,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.851,"p_room":0.9,"age_days":52,"expected_fill_days":123,"reasons":["conf:3","win:mid"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/rivr-senior-mechanical-engineer-power-electronics-packaging","json_url":"https://alion.io/job/rivr-senior-mechanical-engineer-power-electronics-packaging.json","meta":{"generated_at":"2026-10-31T02:59:10Z","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":4223,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":27772},"rest":"https://alion.io/mcp/rest/get_company?id=27772"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frivr-senior-mechanical-engineer-power-electronics-packaging"},{"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%2Frivr-senior-mechanical-engineer-power-electronics-packaging"},{"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%2Frivr-senior-mechanical-engineer-power-electronics-packaging"},{"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/rivr-senior-mechanical-engineer-power-electronics-packaging\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frivr-senior-mechanical-engineer-power-electronics-packaging"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":515486}},{"tool":"search_jobs","arguments":{"company":"rivr.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":515486},"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.
