Each system is built for a specific industry, powered by agents that push real workflows forward. Underneath it all is Atlas, our proprietary platform that keeps customers in control, secure by design, and never locked into one model.\nWhy Now\nBrain Co. is entering its next phase of production deployments on a national scale with an elite team built from Palantir, Google, Meta, and Nvidia, and a growing footprint across government, insurance, health, and financial services.\nJoining now means shaping both the company and a new category of applied AI. Every project here ships to production and is expected to create measurable customer value and impact.\nYou'll work alongside exceptional peers on some of the hardest problems in applied AI. It’s the kind of work you'll still be proud of in ten years from now.\nAbout Brain Co.\nBrain Co. is an applied AI startup founded byElad Gil and Jared Kushner, backed by many of Silicon Valley’s leading builders, including Patrick Collison (CEO of Stripe), Andrej Karpathy (Cofounder of OpenAI), Mike Krieger (CPO of Anthropic), Kevin Weil (CPO of OpenAI), and Aravind Srinivas (CEO of Perplexity).\nWe build AI platforms and applications for the world’s most important institutions, delivering real impact on complex, real-world problems.\nOur progress so far:\nAutomated construction permitting for a sovereign government → 80% faster, unlocking $375M+ in value\n\nOptimized supply chains for a global energy leader →30% lower cost, 99% reliability, preventing $100M+ in losses\n\nStreamlined hospital patient care across national health systems → 40% better outcomes, 80% less admin work\n\nRaised a $30M Series A from top-tier investors\n\nBuilt a team of 40+ AI experts from Tesla, Google DeepMind, NVIDIA, and Databricks\n\nAt Brain Co., co-op interns contribute to real production systems and see their work deployed at global scale.\nAbout the Role\nAs an AI Platform Engineer Intern, you’ll work alongside engineers across Product, ML, and Infrastructure to build the backend services and platform capabilities that power Brain Co.’s AI applications. You’ll contribute to APIs, shared services, developer tooling, and production systems used in enterprise and government environments.\nThis internship is designed for current undergraduate students, specifically juniors and seniors graduating no later than June 2028, who want hands-on experience building real production software. You’ll take on scoped projects across backend systems, distributed services, AI/ML platform integrations, reliability, and developer experience, with mentorship through code reviews, design discussions, and hands-on collaboration with the team.\nWhat You’ll Work On\nBuild and improve backend services and APIs-including REST, gRPC, and event-driven systems-that power AI applications and shared platform capabilities.\n\nTake scoped features from technical design through implementation, testing, deployment, and maintenance.\n\nDevelop modular, reusable platform components and developer-facing tooling that help teams build and ship reliably.\n\nWork with databases, queues, caches, and distributed systems, learning how to handle consistency, retries, idempotency, and failure modes.\n\nImprove latency, throughput, reliability, and cost through profiling, observability, and thoughtful system design.\n\nContribute to systems that support AI inference, data pipelines, and customer-facing workflows.\n\nPartner with Product, ML, Infrastructure, and customer-facing teams to translate open-ended needs into clear technical solutions.\n\nParticipate in code reviews, architecture discussions, and technical problem-solving, and see your work deployed to real users.\n\nYou Might Be a Great Fit If You…\nAre a current undergraduate junior or senior graduating no later than June 2028 and pursuing a degree in Computer Science, Engineering, or a related technical field.\n\nHave strong foundations in data structures, algorithms, object-oriented programming, systems, and databases.\n\nHave experience building software in Go, TypeScript, Rust, Python, Java, C++, or a similar language.\n\nHave built a backend service, API, data-intensive application, or developer tool through coursework, an internship, research, or a personal project.\n\nUnderstand-or are eager to learn-API design, databases, distributed systems, and reliability concepts.\n\nAre comfortable with Git, testing, and debugging, and are interested in cloud or containerized deployment.\n\nEnjoy breaking down ambiguous problems from first principles and communicating your approach clearly.\n\nAre curious, proactive, and excited to own technical problems while seeking feedback when needed.\n\nInternship Details & Benefits\nDates: May 31, 2027 - Aug 6, 2027 or July 5, 2027 - September 10, 2027\n\nCompetitive internship compensation\n\nHands-on mentorship from experienced AI engineers and researchers\n\nOpportunity to work on real production systems used globally\n\nPotential return-offer consideration for future internships or full-time roles\n\nDaily lunches (if onsite)","description_format":"text","description_chars":5220,"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":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","AI Consulting & Integration"],"lifecycle":[{"event":"open","at":"2026-10-30T19:42:34Z"}],"visa":[],"liveness":{"score":65,"band":"ok","label":"Likely open","p_open":1,"p_active":0.903,"p_room":0.72,"age_days":53,"expected_fill_days":96,"reasons":["conf:1","velocity","win:mid","crowd:junior"],"computed_at":"2026-11-05T05:54:30Z"},"pay":null,"html_url":"https://alion.io/job/brain-co-ai-platform-engineer-intern-summer-2027","json_url":"https://alion.io/job/brain-co-ai-platform-engineer-intern-summer-2027.json","meta":{"generated_at":"2026-11-06T01:09:31Z","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":1933,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":2051367},"rest":"https://alion.io/mcp/rest/get_company?id=2051367"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbrain-co-ai-platform-engineer-intern-summer-2027"},{"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%2Fbrain-co-ai-platform-engineer-intern-summer-2027"},{"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%2Fbrain-co-ai-platform-engineer-intern-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/brain-co-ai-platform-engineer-intern-summer-2027\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbrain-co-ai-platform-engineer-intern-summer-2027"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3542507}},{"tool":"search_jobs","arguments":{"company":"brain.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3542507},"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.
