We design all the hardware and software needed to make chips and we make the fabs, tools, and components ourselves.\nWe're looking for exceptional, hands-on people who can iterate to the limits of what's possible.\nfab2 was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.\nAbout the team\nThe Precision Team operates on the nanometer scale. We make lithography, metrology and motion systems that pattern, inspect and characterize our chips in order to push our process to lower nodes.\nAbout the role\nWe are seeking a highly skilled and hands-on Mechanical Engineer to join our team. You will be responsible for designing, prototyping, and building the mechanical systems in our semiconductor fabrication equipment, from stages and frames up to complete systems.\nThis role is for someone who has internalized precision machine design as a discipline and has a proven track record of rapidly prototyping complex precision systems and advancing them to the next stage of production. Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio is generally required to apply: show us the things you’ve actually built!\nResponsibilities\nDesign and iterate on precision machines, motion stages, structural loops, metrology frames, opto-mechanical mounts, test fixtures, and inspection tooling targeting sub-micron to nanometer performance\n\nLead mechanical system integration, alignment procedures, and cross-team coordination with electrical, controls, and optics engineers\n\nDrive mechanical design of frames, stages, and assemblies with GD&T, tolerance analysis, and a practical eye toward manufacturability and assembly\n\nRapidly prototype, build and characterize new designs on the bench using a variety of tools and characterization equipment\n\nSelect and integrate precision components: bearings, encoders, interferometers, actuators, isolators, and dampers\n\nDevelop error budgets and tolerance stack-ups; identify and mitigate dominant error sources (thermal, vibrational, structural, kinematic)\n\nRequired Experience\nDeep experience designing and building precision mechanical systems that had to hit real accuracy and repeatability targets\n\nWorking fluency in precision machine design fundamentals: exact-constraint design, kinematic couplings, flexures, error budgeting, structural loops, tolerance analysis\n\nHands-on prototyping, fabrication, assembly, and alignment experience - you're comfortable on a mill, on a granite surface plate, and behind an interferometer\n\nExperience selecting and integrating precision components (bearings, stages, encoders, isolators, actuators)\n\nExperience with dimensional metrology: interferometry, LVDTs, capacitance probes, autocollimators, and CMMs\n\nNice-to-have\nFormal training in precision engineering\n\nExperience at an early-stage startup\n\nFamiliarity with firmware, controls, or electrical engineering\n\nOpto-mechanical design and alignment experience\n\nWorking at fab2\nWe’re an early-stage hardware startup with solid funding, world-class advisors, and labs/offices in Austin, TX, Lockhart, TX, and San Francisco, CA.\nCompensation: fab2 is committed to fair and equitable compensation practices. We're hiring this role from mid-level through staff. The annual salary range for this role is $130,000 - $200,000. Compensation is determined based on your qualifications and experience. Our total compensation package also includes generous equity in fab2.\nBenefits: fab2 offers the following benefits, subject to applicable eligibility requirements:\nMedical, Dental, and Vision insurance\n\nGenerous Paid Time Off inclusive of Holidays and Sick Time\n\nVisa Sponsorship\n\nLife and Disability Insurance\n\nPaid Parental Leave\n\n401(k) retirement plan\n\nWeekly Learning & Development opportunities\n\nCommuter Benefits including Parking and Late Night Uber rides from the office\n\nLunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and Spindrifts\n\nWe are an equal-opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.\nExport Control Analysis: This position involves access to technology that is subject to U.S. export controls. Any job offer made will be contingent upon the applicant’s capacity to serve in compliance with U.S. export controls.\nfab2, formerly known as Atomic Semi","description_format":"text","description_chars":4569,"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":["Equity","Parental leave","Retirement plans","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Semiconductor Manufacturing","Semiconductor Equipment"],"lifecycle":[{"event":"open","at":"2026-09-26T15:22:14Z"}],"visa":[{"country":"US","licensed_sponsor":false,"adverts_offering_sponsorship_24m":50,"sanctioned_now":false,"evidence":"Offered visa sponsorship in 50 of its adverts here in 24 months","filings_12m":0,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-11-11T07:38:50+00:00","sources":["Alion: sponsorship offered in the employer's own job adverts (24 months)"],"filings_for_role_12m":0}],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.247,"p_room":0.28,"age_days":195,"expected_fill_days":72,"reasons":["conf:1","stale_co","win:tail","crowd:"],"computed_at":"2026-11-11T05:49:22Z"},"pay":{"stated_usd_annual":195000,"is_top_pay":true},"html_url":"https://alion.io/job/fab2-mechanical-design-engineer-lithography-tools","json_url":"https://alion.io/job/fab2-mechanical-design-engineer-lithography-tools.json","meta":{"generated_at":"2026-11-11T08:09:07Z","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":12874,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"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":2218927},"rest":"https://alion.io/mcp/rest/get_company?id=2218927"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffab2-mechanical-design-engineer-lithography-tools"},{"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%2Ffab2-mechanical-design-engineer-lithography-tools"},{"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%2Ffab2-mechanical-design-engineer-lithography-tools"},{"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/fab2-mechanical-design-engineer-lithography-tools\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffab2-mechanical-design-engineer-lithography-tools"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1309744}},{"tool":"search_jobs","arguments":{"company":"fab2.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1309744},"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.
