Our technology is designed to significantly improve the performance of electric motors for drones and robotics, heat sinks, and ultimately the entire energy grid. At its core, Arcturus is developing a new class of carbon nanomaterial-infused metal matrix composites for high-performance conductor applications.\nWhy you should join us\nThis is a ground-floor opportunity to help build something that has never been done before.\nYou would join as an early technical co-op and work closely with Arcturus’ technical team across nanomaterials, additive manufacturing, process engineering, and testing. This is a hands-on role for someone who wants to learn quickly, contribute directly, and help build the experimental foundation for a first-of-its-kind materials platform.\nPurpose\nWe are seeking a Research and Prototyping Engineer Co-op who can support the technical team across experiments, literature research, supplier research, sample preparation, fixture development, testing, and documentation.\nThis role is intentionally broad. You do not need to be an expert in every area, but you should be highly curious, organized, hands-on, and excited to work at the intersection of materials science, advanced manufacturing, and electrification.\nThe role\nThis role will work closely with Arcturus’ technical leads and senior engineers.\nNanomaterials\nBuild and maintain a carbon nanomaterial and powder supplier database, including vendors, material specs, pricing, lead times, and sample availability\n\nHelp organize a recipe matrix for carbon nanomaterial integration, including material type, loading level, feedstock, processing route, and resulting performance\n\nSupport basic nanomaterial handling, sample preparation, documentation, and experimental tracking\n\nAdditive Manufacturing\nHelp build and maintain chamber BOMs, equipment lists, vendor quote trackers, and component comparison tables\n\nSupport fixture and tooling development through CAD, ideally in Onshape or a similar CAD platform\n\nHelp organize a fixture CAD library for experimental setups, sample holders, coupons, and test hardware\n\nSupport additive manufacturing experiments through preparation, documentation, build tracking, and post-build sample handling\n\nProcess Engineering\nSupport flash sintering fixture iterations, including CAD updates, part sourcing, assembly, testing, and documentation\n\nHelp create and improve sample preparation SOPs for polishing, sectioning, mounting, cleaning, labeling, and tracking\n\nSupport cylinder coupon workflows, including sample preparation, processing, inspection, measurement, and documentation\n\nHelp translate experimental procedures into clear, repeatable work instructions and lab notes\n\nTesting and Characterization\nSupport internal materials testing, including Raman spectroscopy, electrical characterization, mechanical characterization, polishing, microscopy, and other methods as needed\n\nHelp prepare samples and data packages for external testing, vendor evaluation, partner validation, and customer-facing demonstrations\n\nCoordinate with external vendors and labs for quotes, sample shipments, testing status, and results tracking\n\nMaintain clear technical documentation, including lab notes, test summaries, experimental results, and lessons learned\n\nBasic qualifications\nCurrently pursuing or recently completed a BS, MS, or PhD in materials science, mechanical engineering, chemical engineering, electrical engineering, physics, chemistry, manufacturing engineering, or a related technical field\n\nStrong technical curiosity and willingness to learn across multiple disciplines\n\nComfortable working hands-on in a lab, shop, or experimental environment\n\nHighly organized, detail-oriented, and reliable with documentation\n\nAble to take direction, ask good questions, and execute quickly\n\nExcited to work in a fast-moving startup environment where priorities can change quickly\n\nPreferred qualifications\nExperience working in a research lab, hardware startup, university lab, or advanced manufacturing environment\n\nExperience with carbon nanomaterials, graphene, carbon nanotubes, metallurgy, additive manufacturing, powder processing, or materials characterization\n\nFamiliarity with Raman spectroscopy, microscopy, SEM/EDS, electrical testing, mechanical testing, polishing, or sample preparation\n\nCAD experience, ideally with Onshape or similar tools\n\nExperience with literature reviews, supplier research, technical databases, or experimental documentation\n\nWhat we offer\nHands-on technical experience with first-of-its-kind materials and manufacturing challenges\n\nThe chance to work closely with senior technical leads across nanomaterials, additive manufacturing, process engineering, and testing\n\nReal ownership over useful technical projects, databases, fixtures, experiments, and documentation\n\nUp to a one-year co-op experience with direct exposure to early-stage deeptech startup building. If the fit is right, we'd love to bring you on to the team!\n\nIf this role excites you, even if you do not check every box, we’d love to hear from you. We’d rather work with a fast learner who cares deeply about the work than someone with years of experience but little curiosity.","description_format":"text","description_chars":5401,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Advanced Materials","Materials Science & Nanotechnology"],"lifecycle":[{"event":"open","at":"2026-09-09T04:24:10Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.144,"p_room":0.28,"age_days":154,"expected_fill_days":32,"reasons":["conf:2","win:tail","crowd:junior"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/arcturus-engineering-internship","json_url":"https://alion.io/job/arcturus-engineering-internship.json","meta":{"generated_at":"2026-11-08T05:15:37Z","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":11394,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-09T00:00:00Z"}},"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":456162},"rest":"https://alion.io/mcp/rest/get_company?id=456162"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Farcturus-engineering-internship"},{"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%2Farcturus-engineering-internship"},{"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%2Farcturus-engineering-internship"},{"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/arcturus-engineering-internship\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Farcturus-engineering-internship"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":560814}},{"tool":"search_jobs","arguments":{"company":"arcturus.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":560814},"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.
