Founded in 2023 and backed by leading investors including Andreessen Horowitz, Sam Altman, and Felicis, we're committed to providing clean, modular, and scalable power that meets the rapidly growing demands of AI infrastructure. Our mission is to make sustainable renewable energy always available and almost free, enabling technological advancement while protecting our planet.\nWe are seeking a Mechanical Engineer to join our optics team. The team owns the full design-to-commissioning lifecycle for our tracker hardware: precision optical elements and the structures that position them, solar tracking architectures, structural analysis under wind and gravity loading, and the instrumentation that turns prototypes into measured systems. The core problem is deceptively hard: hold optical precision on a large structure that moves all day, outdoors, under wind, gravity, and thermal swings, all at a cost that can scale to thousands of units.\nAt its core, this is a builder's role. Your main focus will be optomechanical assemblies: designing, fabricating, assembling, aligning, and testing the hardware that positions optical elements (lenses and mirrors, for example) on our trackers. The full loop is yours: idea to CAD to built hardware to test data, learning from what breaks and turning the next revision around in days, not months. You will spend most of your time hands-on in the shop, at the assembly bench, and on the test stand. The work spans structures, optics, precision assembly, sensors, and the code and AI agents that read them. This is an AI-native team: agents already drive our simulation campaigns and babysit our long-running tests, and we expect you to work at that level from day one. Everything around your hardware that is code, calculation, or documentation is something an agent should be running for you. Expect real ownership, a steep learning curve, and senior engineers who will review your work closely and push you to grow fast.\nThis position is based in Miami, FL. If selected, relocation to Miami, FL is required. Exowatt provides relocation assistance.\nKey Responsibilities:\nDesign, build, and align optomechanical assemblies for the tracker platforms (optic mounts, frames, and alignment and adjustment features), owning them end to end: idea, CAD model, fabricated parts, assembled and working hardware\nBuild hardware hands-on: assemble prototypes and test articles, fixture and align optics, work through fit-up issues at the bench, and turn what you learn into the next design revision fast\nSupport test stand build, instrumentation, and commissioning: sensor mounting, wiring, calibration, DAQ integration, first light, and commissioning runs\nTroubleshoot electromechanical systems hands-on: wiring harnesses, sensors, motor drivers, encoders, microcontrollers, and the code talking to them; multimeter, oscilloscope, and Python debugger in the same afternoon, root-causing failures and driving corrective actions back into the design\nWork AI-native: drive the scripting, analysis, and documentation around your hardware with AI coding agents, and help make the team's test and simulation infrastructure agent-ready so campaigns can run overnight without a human babysitting them\nBuild and revise CAD models in PTC Creo and SolidWorks; develop drawing packages with GD&T (ASME Y14.5) for fabrication, weldments, and assemblies, run tolerance stack-up analyses, and iterate against fabrication feedback\nSupport structural analysis across tracker platforms: first-principles hand calculations, ANSYS FEA for detailed analysis, SAP2000 for code-checked wind-load combinations under ASCE 7-22\nMaintain subsystem-level BOMs and handle vendor follow-ups: slew drives, optical components, fasteners, sheet-metal fabrication\nDocument analysis, build progress, and decisions on the team wiki: methodology pages, test plans, weekly status, design memos\nPresent and defend your own work in design reviews, growing into ownership of larger subsystems over time\nCollaborate with controls, software, and supply chain teams, and with external engineering partners and vendors\nQualifications:\nBS or MS in Mechanical Engineering, Aerospace Engineering, or a closely related discipline\n1+ years of hands-on build or design experience with real hardware; internships, co-ops, research labs, and major project-team roles count\nStrong fundamentals in math and physics: you reason from first principles, estimate before you compute, and check every result against known limits before you believe it; we probe this hard in interviews\nWorking knowledge of a parametric CAD tool; the team uses PTC Creo and SolidWorks\nWorking understanding of GD&T (ASME Y14.5) and tolerance stack-up analysis\nFamiliarity with common fabrication processes (machining, sheet metal, welding, 3D printing) and design-for-manufacturability and assembly (DFM/DFA) principles\nAbility to back up simulation with first-principles hand calculations, and to run structured root-cause analysis when hardware misbehaves\nA track record of building real hardware: internships, capstone projects, FSAE, solar car teams, robotics, makerspaces, or independent builds all count; bench experience matters more than coursework grades\nThe drive to own the full cycle yourself: take an idea to CAD, to built hardware, to test, learn from the mistakes, and iterate quickly rather than handing steps off to others\nComfort with shop and bench work: hand tools, fixturing, assembly, and careful mechanical work on precision hardware\nCoursework or hands-on project experience in solid mechanics, statics, dynamics, and finite element analysis\nComfort troubleshooting electromechanical systems hands-on: wiring harnesses, sensors, motor drivers, encoders, microcontrollers, and the firmware or software talking to them\nFluency with AI coding agents (Claude Code, Codex, or similar) as a daily engineering tool: you use them to write most of your code, and you own every line they produce, reviewed, tested, and understood; expect us to ask you to show how you work with AI the same way we ask about your bench skills\nThe instinct to make work agentic: you can decompose a workflow into steps an agent can execute, with clean interfaces, verifiable checkpoints, and guardrails, and you have the judgment to catch an agent when it is confidently wrong; engineers who can direct several agents at once will outrun those who type everything themselves, and we hire the former\nStrong written communication: you can document your work clearly enough that the next engineer can pick it up without asking you\nThe temperament to hold your ideas loosely: designs evolve weekly and priorities shift on real evidence; engineers who can let go and update move fastest\nPreferred Qualifications:\nHands-on experience assembling or aligning optical or precision mechanical hardware\nExperience with motion components and mechanisms: bearings, actuators, gear and slew drives, bolted and welded joint design\nExposure to design validation and reliability practices: DFMEA, DVP&R, or environmental qualification testing\nCoursework or research in optical systems, photonics, heat transfer, or solar energy\nHands-on experience with ANSYS, SAP2000, or another FEA package beyond classroom problem sets\nPython or MATLAB scripting: kinematics, data reduction, plotting\nExperience building agentic systems around real hardware or simulation: agents driving instruments, CAD, or simulation models through tool interfaces (MCP or similar), running parameter sweeps overnight, and summarizing the results; or any project where you gave an AI real levers and made its output trustworthy\nLab or test-stand experience involving DAQ, instrumentation, or calibration\nFamiliarity with controls fundamentals: open-loop versus closed-loop, sensor fusion concepts\nInterest in solar energy, heliostats, or large-scale renewable infrastructure\nAdditional Requirements:\nWillingness to work extended hours and occasional weekends when builds, test campaigns, or program deadlines demand it\nAbility to lift up to 25 lbs unassisted, and to work safely with shop tools, ladders, and lifts with appropriate PPE\nAbility to work outdoors in Miami heat during assembly and field testing\nOccasional travel to fabricators, vendors, and field sites","description_format":"text","description_chars":8452,"description_truncated":false,"requirements":{"experience_years_min":1,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Relocation assistance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Energy Storage","Solar Energy"],"lifecycle":[{"event":"open","at":"2026-09-05T12:04:28Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 3","filings_12m":3,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":202500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":44,"band":"fade","label":"Fading","p_open":1,"p_active":0.737,"p_room":0.6,"age_days":105,"expected_fill_days":118,"reasons":["conf:0","win:late","crowd:junior"],"computed_at":"2026-11-04T06:34:25Z"},"pay":null,"html_url":"https://alion.io/job/exowatt-mechanical-engineer-optical-systems-miami-fl-2","json_url":"https://alion.io/job/exowatt-mechanical-engineer-optical-systems-miami-fl-2.json","meta":{"generated_at":"2026-11-04T06:46:59Z","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":10634,"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":4909},"rest":"https://alion.io/mcp/rest/get_company?id=4909"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fexowatt-mechanical-engineer-optical-systems-miami-fl-2"},{"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%2Fexowatt-mechanical-engineer-optical-systems-miami-fl-2"},{"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%2Fexowatt-mechanical-engineer-optical-systems-miami-fl-2"},{"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/exowatt-mechanical-engineer-optical-systems-miami-fl-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fexowatt-mechanical-engineer-optical-systems-miami-fl-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":263005}},{"tool":"search_jobs","arguments":{"company":"exowatt.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":263005},"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);
