We automate paperwork with AI, helping our customers get life-saving innovations to patients years faster. Collate is an end-to-end solution, powering every step of drug, diagnostic, and medical device development-from concept to market.\nOur CEO Surbhi Sarna is a former General Partner at Y Combinator. Surbhi founded nVision Medical, which developed a new method to detect ovarian cancer and was acquired by Boston Scientific. Our CTO Nate Smith is a former Visiting Partner at Y Combinator and founder of Lever. Our AI researchers, engineers, and designers have worked at Google, Nvidia, Meta, Netflix, Amazon, AirBnB, Hippocratic AI, and Grail, and 40% of our team are former founders.\nWe’re an elite team, with $125M in funding from top investors (Redpoint, First Round Capital, CRV, Conviction, Y Combinator) and leaders in healthcare and AI. This is a rare chance to join an early-stage company with world-changing potential, experienced founders, and resources to execute at scale.\nAbout the Role\nWe’re looking for a Full-Stack Engineer (Backend-leaning) to design and build the systems and user-facing features that power Collate. You’ll spend most of your time on backend challenges-APIs, services, and infrastructure-but you’ll also ship end-to-end features.\nThis is an opportunity to help define our technical foundation, collaborate directly with design and product, and shape how our users experience Collate from day one.\nModern Tech Stack\nCollate uses a modern tech stack, targeting a highly reliable and available platform. We use Go for scalable backend services, TypeScript & React for frontend development, and Python for AI & ML services. Our infrastructure is hosted on AWS with Kubernetes for orchestration and Terraform + Argo CD for configuration management. Key systems include S3, PostgreSQL, Kafka, OpenSearch, LLMs, and other AI models.\nWhat You’ll Do\nDesign and scale backend services, APIs, and data pipelines that power Collate’s products.\nDeliver end-to-end, production-ready features in partnership with product, design, and AI engineering.\nBalance iteration speed with technical rigor to ensure systems scale reliably.\nCreate internal tools and workflows that accelerate engineering productivity.\nShare responsibility for production systems, including participating in on-call rotation.\nWhat We’re Looking For\nHave experience building across the stack, with deeper strength in backend systems.\nEnjoy taking features from idea → backend architecture → polished UI.\nCare deeply about both technical robustness and the end user experience.\nAre motivated by ambiguity, eager to pick up missing knowledge, and excited to solve novel problems.\nValue speed, pragmatism, and scrappiness but know when to design for robustness.\nHave been an early-stage engineer or startup founder-or aspire to work at that level of ownership.","description_format":"text","description_chars":2931,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Document AI","Clinical Trial Software"],"lifecycle":[{"event":"open","at":"2026-09-11T06:42:27Z"},{"event":"open","at":"2026-09-26T17:59:10Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.129,"p_room":0.28,"age_days":660,"expected_fill_days":30,"reasons":["conf:1","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/collate-full-stack-software-engineer-backend-leaning","json_url":"https://alion.io/job/collate-full-stack-software-engineer-backend-leaning.json","meta":{"generated_at":"2026-10-30T14:23:19Z","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":1772,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":673486},"rest":"https://alion.io/mcp/rest/get_company?id=673486"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcollate-full-stack-software-engineer-backend-leaning"},{"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%2Fcollate-full-stack-software-engineer-backend-leaning"},{"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%2Fcollate-full-stack-software-engineer-backend-leaning"},{"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/collate-full-stack-software-engineer-backend-leaning\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcollate-full-stack-software-engineer-backend-leaning"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":718666}},{"tool":"search_jobs","arguments":{"company":"collate.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":718666},"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.
