Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.\nOur mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable. We believe abundant nuclear energy will lead to a post-scarcity society. \nWe were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms. \nOur lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production. \nWe are a mission-driven company with a culture of urgency, accountability, and transparency. \nHelp us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. \nAbout This Role\nAs a General Matter Software Engineering Intern, you will help develop performant, safe, and high-quality software. Your work will support code where reliability, performance, and safety are of utmost importance. You will work closely with cross-functional teams, including electrical engineers, software engineers, chemical engineers, manufacturing engineers, nuclear engineers, materials scientists, and physicists. If you seek high-impact work and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to reach out to join our team.\nWe're hiring interns across three focus areas:\nBackend interns will help build high-performance services and APIs that coordinate control systems, manage state across distributed hardware, and expose interfaces for monitoring and operations.\nDistributed systems interns will support the development of fault-tolerant coordination systems, real-time data pipelines processing high-throughput sensor telemetry, and the infrastructure that keeps critical systems running reliably at scale.\nTooling interns will help build the developer platforms, CI/CD systems, observability tools, and deployment infrastructure that let our team iterate rapidly and safely in a production environment where mistakes have physical consequences.\nResponsibilities\nAssist in designing and implementing high-performance software systems in C++ and Python, with a focus on reliability and maintainability.\nSupport the architecture of solutions, contributing to decisions around system design, performance trade-offs, and technology selection.\nParticipate in technical design reviews and code reviews, learning and helping uphold engineering best practices across the team.\nHelp build and maintain automated testing and CI/CD pipelines to support software quality at scale.\nWork closely with senior engineers, contributing to progress on complex, ambiguous technical problems.\nBasic Qualifications\nCurrent undergraduate or graduate student pursuing a degree in Computer Science, Engineering, or a related discipline.\nProficiency in C++ and/or Python.\nStrong CS fundamentals, such as algorithms, data structures, concurrency, and system design.\nCollaborative team member who thrives in fast-paced, multidisciplinary environments and is eager to learn.\nPreferred Skills and Experience\nExposure to distributed systems, observability tooling, or infrastructure as code.\nExperience with Python ecosystems for data pipelines, automation, or backend services.\nCoursework or project experience with C++ performance optimization, profiling, or low-level systems programming.\nFamiliarity with Linux system programming, including threading models, IPC, or low-level kernel interfaces.\nEvidence of exceptional ability (prior projects, portfolio of work, completed products, etc).\nAdditional Requirements\nAbility to work extended hours and weekends as necessary.\nEqual Opportunity Employer\nGeneral Matter is an Equal Opportunity Employer; employment with General Matter 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.\nCompensation and Benefits\nThe hourly pay range for this internship is $32-$46 per hour, depending on the candidate's current standing in school (i.e. sophomore, senior).\nInterns will receive a monthly housing stipend and are eligible for overtime pay. Please note that the stated hourly range is an estimate and may be adjusted based on market conditions, business needs, or other factors.","description_format":"text","description_chars":4992,"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":["Nuclear Energy","Nuclear Engineering"],"lifecycle":[{"event":"open","at":"2026-09-06T07:14:47Z"}],"visa":[],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.417,"p_room":0.44,"age_days":70,"expected_fill_days":49,"reasons":["conf:1","stale_co","velocity","win:tail","crowd:junior,brand"],"computed_at":"2026-10-29T05:49:05Z"},"pay":{"stated_usd_annual":92000,"is_top_pay":true},"html_url":"https://alion.io/job/general-matter-summer-2027-internship-software-engineering","json_url":"https://alion.io/job/general-matter-summer-2027-internship-software-engineering.json","meta":{"generated_at":"2026-10-29T12:02:23Z","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":17979,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":171806},"rest":"https://alion.io/mcp/rest/get_company?id=171806"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgeneral-matter-summer-2027-internship-software-engineering"},{"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%2Fgeneral-matter-summer-2027-internship-software-engineering"},{"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%2Fgeneral-matter-summer-2027-internship-software-engineering"},{"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/general-matter-summer-2027-internship-software-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgeneral-matter-summer-2027-internship-software-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":437873}},{"tool":"search_jobs","arguments":{"company":"generalmatter.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":437873},"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.
