Using free-space laser links in Medium Earth Orbit (MEO), we move petabytes of data between any two points on Earth as an alternative to subsea or terrestrial fiber. EON recently closed a $10.75M seed financing round led by Andreessen Horowitz and General Catalyst in their first-ever co-led space deal. EON is building out of its R&D center in Culver City.\nToday, approximately 95% of the global internet travels through a few hundred subsea fiber-optic cables, infrastructure designed in the early 2000s that has gone largely unchanged. Demand for new fiber has never been higher, but laying it is extraordinarily difficult: permits, ocean geology, and geopolitical boundaries make every new cable a years-long, billion-dollar undertaking. That bottleneck is a liability with cables at constant risk of being cut, whether by accident or adversarial action, and no amount of ground-based investment can fully solve it.\nThe Role\nOur optics have to be mounted to sub-micron precision and stay aligned under thermal swings, vibration, and handling. We are seeking optomechanical engineers to design the assemblies the beam path rides on and the alignment schemes that keep them true from bench to field. Your work may look like partnering with Optical Design on tolerancing and alignment budgets and with Thermal on the structural-thermal-optical behavior that drives alignment stability.\nResponsibilities\nDesign optomechanical assemblies for EON's laser communications terminals, and carry them from concept through first light\n\nDesign mounts, flexures, and kinematic schemes that hold sub-micron alignment under real loads\n\nContribute to the line-of-sight error budget: structural dynamics, tolerance stack-up, jitter analysis, and pointing calibration\n\nAnalyze mechanical and thermal stability of the optical train, supporting structural-thermal-optical (STOP) analysis in partnership with Thermal\n\nDrive tolerance and alignment-budget trades with Optical Design, where optical and mechanical performance are tightly coupled\n\nExecute alignment verification and metrology, confirming assemblies meet their budgets on the bench and after environmental exposure\n\nSupport environmental test and qualification (vibration, shock, thermal-vac) that proves assemblies hold alignment through launch and field conditions\n\nBasic Qualifications\nA degree in mechanical engineering, optical engineering, physics, or a related discipline\n\nOptomechanical design experience, including mounts, flexures, or kinematic design\n\nHands-on alignment and integration of precision optical assemblies\n\nProficiency in 3D CAD (NX, SolidWorks, Creo, or equivalent)\n\nComfort moving fast and making sound calls without complete data\n\nPreferred Experience\nSpace or airborne optomechanical hardware, including launch-load and on-orbit stability design\n\nLasercom or optical communications terminal experience\n\nStructural FEA (ANSYS Mechanical or equivalent) and structural-thermal-optical reasoning\n\nAthermalization and materials selection for stability: CTE matching, low-expansion materials (Invar, Zerodur, silicon carbide), and bonded versus mechanical mounting trades\n\nFiber-coupling optomechanics: fiber-to-collimator alignment, fiber positioners, or coupling-stability design\n\nAlignment-verification and metrology methods for precision optical hardware\n\nEnvironmental test and qualification (vibration, shock, thermal-vac) for precision hardware\n\nCleanliness and contamination control for optical assemblies, including handling, bake-out, and outgassing requirements\n\n A note on level and background: We hire this role at all levels, from Associate through Senior and Principal Optomechanical Engineer, and calibrate title, scope, and compensation to your experience. If this list doesn't perfectly match your background still reach out. We are always looking for exceptional people from many disciplines.\nWhat this job is really like\nEON is a lean company by design. There is no program office, no requirements team handing you specs, and no army of analysts. You will build the models, make the calls on incomplete data, and be forced to defend and revise them. You will spend meaningful hands-on time in the lab, not just in reviews. If you do your best work inside a large, well-resourced program, this isn't it. If you want your fingerprints on a Tbps-class link from the start, this is it.\nCompensation + Benefits\nIn addition to base salary (to be determined on a case by case basis), compensation for this role includes:\nEON believes the business should be primarily employee owned. In turn, all compensation offers include company stock options for FTEs.\n\nComprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.\n\nPaid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).\n\nRelocation assistance to Los Angeles available.\n\nA real equipment and lab budget.\n\nLocation: Culver City, CA (onsite).\nEndeavor Optical Network is an Equal Opportunity Employer; employment with EON is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.","description_format":"text","description_chars":5500,"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":["Dental insurance","Parental leave","Relocation assistance","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["AI for Science"],"lifecycle":[{"event":"open","at":"2026-09-12T06:26:52Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.265,"p_room":0.28,"age_days":92,"expected_fill_days":25,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-11-04T06:34:25Z"},"pay":null,"html_url":"https://alion.io/job/eonsystems-optomechanical-engineer-all-levels","json_url":"https://alion.io/job/eonsystems-optomechanical-engineer-all-levels.json","meta":{"generated_at":"2026-11-04T18:10:05Z","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":27924,"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":720034},"rest":"https://alion.io/mcp/rest/get_company?id=720034"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Feonsystems-optomechanical-engineer-all-levels"},{"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%2Feonsystems-optomechanical-engineer-all-levels"},{"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%2Feonsystems-optomechanical-engineer-all-levels"},{"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/eonsystems-optomechanical-engineer-all-levels\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Feonsystems-optomechanical-engineer-all-levels"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":798057}},{"tool":"search_jobs","arguments":{"company":"eon.systems","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":798057},"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.
