The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads.\nLightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter!\nIf you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.\nLightmatter is (re)inventing the future of computing with light!\nAbout this job \nIn this internship, you will build tools that automate how Lightmatter creates and checks the mechanical drawings behind our advanced photonic packages. As a member of the Packaging team, you will build a toolset that generates substrate and package drawings and runs GD&T sanity checks on them. The capability you build will be used on all upcoming substrate and package tapeouts, so your work will go into real product development from day one. You will also work on experiments that feed into a fundamental understanding of coupled thermal-structural-optical physics. \nYou will be mentored by experienced packaging engineers while learning how package stack-ups, tolerancing, and drawing standards come together in leading-edge products for AI and high-performance compute. You will also see how drawing quality affects assembly, optical alignment, and reliability.\nResponsibilities:\nBuild tools to automate the creation of substrate and package drawings from package design data, reducing manual CAD and drafting effort.\nDevelop automated GD&T sanity checks that catch common drawing errors before release, such as missing or inconsistent callouts, datum scheme issues, and tolerance conflicts.\nWork with packaging, substrate design, and system engineers to capture drawing requirements, templates, and conventions, and turn them into repeatable workflows.\nValidate your tools against existing released drawings and iterate based on feedback from engineers using them.\nPlan and execute physical DOEs, including test setup, measurement, and data analysis, to build fundamental understanding of coupled thermal-structural-optical physics. \nRequirements: \nCurrently pursuing a BS or MS in Mechanical Engineering or a related field.\nCoursework in Engineering Drawing, Manufacturing Processes, Thermodynamics and Heat Transfer, Engineering Mechanics, Strength of Materials, Design of Machine Elements, and Computational Design.\nProgramming proficiency in Python (or a similar language) for scripting, data processing, and automation.\nFamiliarity with CAD tools such as SolidWorks or Creo.\nHands-on prototyping experience through coursework, capstone projects, research labs, or personal projects. Experience building, iterating, and validating physical assemblies is strongly valued.\nWillingness and curiosity to learn from an exciting team!\nPreferred Qualifications\nExposure to Geometric Dimensioning and Tolerancing (GD&T) and tolerance analysis concepts, including ASME Y14.5.\nInternships, capstone, thesis, or research projects involving precision mechanical assembly, optical systems, or microelectronics packaging.\nExperience using AI/ML tools or LLMs to build design automation workflows, such as automating tolerance analysis, CAD scripting, FMEA generation, or simulation post-processing.\nOur internship hourly rates are a standard pay determined based on the position and your location, year in school, degree, and experience.\nHourly Rate in USD\n$43—$47 USD\nBenefits\nComprehensive Health Care Plan (Medical, Dental & Vision)\nRetirement Savings Matching Program\nLife Insurance (Basic, Voluntary & AD&D)\nGenerous Time Off (Vacation, Sick & Public Holidays)\nPaid Family Leave\nShort Term & Long Term Disability\nTraining & Development\nCommuter Benefits\nFlexible, hybrid workplace model\nEquity grants (applicable to full-time employees)\nBenefits eligibility may vary depending on your employment status and location. Lightmatter recruits, employs, trains, compensates, and promotes regardless of race, religion, color, national origin, sex, disability, age, veteran status, and other protected status as required by applicable law.\nExport Control\nCandidates should have capacity to comply with the federally mandated requirements of U.S. export control laws.","description_format":"text","description_chars":4596,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Life insurance","Parental leave"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Chips & Accelerators","Optics & Photonic Components"],"lifecycle":[{"event":"open","at":"2026-11-12T03:12:48Z"}],"visa":[{"country":"US","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"H-1B filings in 12 months: 27 · green card filings: 1","filings_12m":27,"filings_prev_12m":14,"green_card_filings_12m":1,"median_offered_wage_usd":177679,"route":null,"cap_exempt":false,"checked_at":"2026-11-12T07:36:15+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":0}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":0,"expected_fill_days":50,"reasons":["conf:1","velocity","win:early","comp:junior"],"computed_at":"2026-11-12T10:38:37Z"},"pay":{"stated_usd_annual":94000,"is_top_pay":true},"html_url":"https://alion.io/job/lightmatter-packaging-mechanical-design-internship-summer-2027","json_url":"https://alion.io/job/lightmatter-packaging-mechanical-design-internship-summer-2027.json","meta":{"generated_at":"2026-11-13T01:25:02Z","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":3112,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"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":16141},"rest":"https://alion.io/mcp/rest/get_company?id=16141"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flightmatter-packaging-mechanical-design-internship-summer-2027"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Flightmatter-packaging-mechanical-design-internship-summer-2027"},{"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%2Flightmatter-packaging-mechanical-design-internship-summer-2027"},{"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/lightmatter-packaging-mechanical-design-internship-summer-2027\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flightmatter-packaging-mechanical-design-internship-summer-2027"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4132903}},{"tool":"search_jobs","arguments":{"company":"lightmatter.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4132903},"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.
