We're on a mission to make every R&D dollar count.\nDeveloping new medicines is a societal imperative to improve human health and reduce medical costs. Brilliant science needs effective management to develop breakthrough medicines that reach patients. We aim to bring the same level of sophistication to scientific development that modern tools brought to software development. While software teams can ship updates daily, R&D organizations face unique challenges: years long development cycles, complex interdependencies, and high-stakes decisions that can make or break billion dollar programs.\nFounded by early Benchling leaders, we just emerged from stealth with $20M in funding from 8VC, Andreessen Horowitz, Insight Partners, Definition, and Haystack to transform how biotech companies operate. Our customers are working on society's most important challenges, including neurodegeneration, cancer, metabolic disease, and biomanufacturing. We're looking for engineers who are excited about building software that helps scientific organizations operate more effectively.\nThe Role\nWe're seeking a Senior Backend Engineer to join our growing team in San Francisco. You'll work with our team to create complex but intuitive products to manage R&D.\nChallenges You'll Tackle\nComplex Decision Making: Build interactive tools that help organizations model different paths to market for their discoveries, assessing complex trade offs between time, money, and technical risk. Our users need to understand how decisions today affect their programs years into the future.\nOrganizational Alignment: Create intuitive interfaces that help diverse teams (scientists, program managers, executives) understand how their work connects to broader company goals. This includes designing clear ways to visualize complex dependencies and communicate progress across teams.\nScientific Operations: Design interfaces that scientists and researchers use daily to manage their studies, track progress, and coordinate with their teams. This requires crafting experiences that empower rather than get in the way of work.\nAI Powered R&D Management: Leverage LLMs to help teams generate and evaluate scenarios, infer scientific progress and risks from unstructured data, and surface critical insights from across their R&D portfolio.\nWhat Sets You Apart\nComplexity: You understand how to build backends for complex, interconnected systems where changes in one area cascade across multiple dimensions. You're excited about creating infrastructure that handles the unique challenges of long term, high stakes R&D programs.\nAgency: You're drawn to environments where you can shape both the technical architecture and product direction. You enjoy the responsibility of building foundational systems that will scale, balancing the speed needed at an early stage company with the craftsmanship required for complex, mission critical software.\nCuriosity: You're genuinely curious about how breakthrough products are developed and excited about building software that helps scientific organizations operate more effectively. You want your technical work to contribute to bringing medicines and other innovations to market.\nQualifications\nRequired\n6-8 years of backend development experience with production systems at scale\n\nDeep expertise in Typescript, NestJS, PostgreSQL\n\nTrack record of building complex, scalable, reliable cloud-based software\n\nExperience with cloud platform (AWS/Azure/GCP) and containerization\n\nStrong experience in data modeling and API design\n\nCollaborative mindset with proven track record of working effectively in small, fast-moving engineering teams\n\nPreferred\nAI/ML integration with OpenAI, Anthropic, or similar LLM providers\n\nPrompt engineering and RAG implementation experience\n\nFull-stack capabilities - can contribute to frontend when needed (React/TypeScript)\n\nTrack record of mentoring other engineers","description_format":"text","description_chars":4069,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-09-12T04:11:44Z"},{"event":"open","at":"2026-09-25T23:31:52Z"}],"visa":[],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.445,"p_room":0.28,"age_days":453,"expected_fill_days":29,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/orchestra-senior-backend-engineer","json_url":"https://alion.io/job/orchestra-senior-backend-engineer.json","meta":{"generated_at":"2026-11-02T20:41:24Z","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":28926,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":687798},"rest":"https://alion.io/mcp/rest/get_company?id=687798"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Forchestra-senior-backend-engineer"},{"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%2Forchestra-senior-backend-engineer"},{"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%2Forchestra-senior-backend-engineer"},{"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/orchestra-senior-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Forchestra-senior-backend-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":793337}},{"tool":"search_jobs","arguments":{"company":"orchestra.bio","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":793337},"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.
