Our systems deliver PPM-level trace analysis on the fluids inside industrial machines and datacenters. That lets us catch wear trends like bearing failures or coolant contamination in real time, weeks to months before a catastrophic failure. We raised a $31M Series A led by Nava Ventures in June 2026.\nOur team is a tightly knit group of builders, dropouts, and industry veterans. We don't build things that are good enough; we build things that are 100x better.\nThe Challenge\nWe are moving from prototypes to fielded hardware across two systems:\nOmen Scout: for closed-loop hydraulic and lubricating oils.\n Omen Sentry: for direct-to-chip liquid cooling loops (typically water/glycol mixtures).\nOur Irvine engineers need parts, fixtures, and prototype builds turned around fast. We need a hands-on technician who can take a drawing or a rough sketch and come back with a finished part or a working assembly, so the team can iterate faster. This is not a production line.\nWhat You Will Do\nBuild Prototypes and Test Rigs: Assemble sensor prototypes, sub-assemblies, and the rigs we test them on, working from drawings, sketches, and quick conversations with engineers.\nMake Parts and Fixtures: Machine one-off parts, fixtures, and tooling on our mills and lathes, often the same day they're needed.\nPlumb and Test: Build the oil and coolant loops our sensors run on, help run leak, pressure, and flow tests, and report what you see back to engineering.\nKeep the Shop Ready: Maintain machines and tools, track materials and stock, and keep the shop safe and organized for the next build.\nWhat We Are Looking For\n3+ years of hands-on mechanical work as an R&D, prototype, or test technician, or as a machinist who also assembles what they make.\nYou work from drawings (including GD&T), sketches, and CAD models, and you check your own work with calipers, micrometers, and gauges.\nYou have built prototype assemblies, fixtures, or test rigs yourself, from raw parts to a finished build.\nYou work directly with engineers, take a rough request to a finished part on your own, and speak up when a design will be hard to make.\nNice to Have\nMachinist experience: setting up and running mills and lathes, manual or CNC, to make parts and fixtures. This is the biggest plus for this role.\nFluid systems: tubing and fittings (Swagelok, AN), pumps, and leak or pressure testing.\nA mix of mechanical and electrical skills (wiring, soldering, sensors), or a track record of building things on your own outside work.\nCompensation & Benefits\nBase Range of 100k to 160k + Equity\nBenefits\n- 100% medical, dental & vision coverage (for you)\n- Flexible PTO\n- WFH setup stipend\n- Free food & snacks\n- Daily in-office dinner provided\nWhy Omen?\nWe take physics seriously, but we don't let red tape slow us down. You will be the person who turns our engineers' ideas into real parts and working hardware. If you like building with your hands and want to do it for hardware that protects the most expensive infrastructure on the planet, we want to talk to you.","description_format":"text","description_chars":3164,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Industrial IoT (IIoT)"],"lifecycle":[{"event":"open","at":"2026-10-31T06:08:29Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":3,"expected_fill_days":30,"reasons":["conf:3","win:early"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/omen-mechanical-technician","json_url":"https://alion.io/job/omen-mechanical-technician.json","meta":{"generated_at":"2026-11-04T03:41:29Z","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":5734,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"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":2335166},"rest":"https://alion.io/mcp/rest/get_company?id=2335166"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fomen-mechanical-technician"},{"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%2Fomen-mechanical-technician"},{"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%2Fomen-mechanical-technician"},{"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/omen-mechanical-technician\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fomen-mechanical-technician"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3562832}},{"tool":"search_jobs","arguments":{"company":"omen.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3562832},"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.
