Patients wait weeks for therapies that can't wait.\nSodalis is building AI agents that run those operations end to end: reading and validating prescriptions, handling phone calls, and moving prescriptions through eligibility and fulfillment. The ambition goes beyond that. We want to be the rails every specialty prescription runs on, and the first system to perform clinical review at the standard of a pharmacist.\nWe're already in production, processing tens of thousands of prescriptions a week. Backed by Gradient Ventures (Google's AI fund), and founded by veterans of Apple's Applied ML, Included Health, and Avella Specialty Pharmacy (scaled to $1.5B+ before its acquisition by OptumRx).\nThe Opportunity\nEvery pharmacy works from the same building blocks: prescriptions, directions, insurance claims, rejects. But each one handles them a little differently, so today every implementation means custom code. We want implementation to be configuration, done by a technical solutions team using internal tools, with no engineer in the loop. That's the engine you'd build.\nIt's a classic backend problem with real stakes. You'll model the shared primitives so one system can absorb each pharmacy's nuances, build the configuration layer and the backend behind the tools, and define the contract between the engine and the people tuning it. That includes how new versions roll out only to the customers who want them, on a system that's already live and can't break.\nYou'd own the application platform: the domain model, configuration layer, and tooling. You'd work directly with the founders and the early engineering team on the architecture and where the platform goes.\nWhat you'll do\nModel the shared primitives (prescriptions, directions, insurance outcomes) and build the backend that turns each pharmacy's differences into configuration, so one system serves many pharmacies.\n\nDecide where the line between configuration and code sits: what a solutions team can safely configure, and what stays in the engine.\n\nBuild the backend services and APIs behind the internal tools a solutions team uses to implement a new customer without an engineer.\n\nDefine and version the contract between our engines and whoever configures them, so upgrades ship safely and selectively.\n\nShip changes to a system that's live, where every prescription is a patient and a bad migration isn't an outage, it's a delayed therapy. Zero-downtime rollouts and safe versioning are table stakes here.\n\nPartner with the founders and early engineering team on architecture and roadmap.\n\nWhat we're looking for\n5+ years building backend systems in production.\n\nStrong system design: you can take an open prompt, design a coherent system, and explain the trade-offs clearly.\n\nSolid data modeling and API design: you build systems that generalize, not one-offs.\n\nYou've built something config-driven that other people operated: a rules engine, a multi-tenant platform, a feature-flag or rollout system, a workflow DSL. You know where those designs go wrong.\n\nYou've shipped 0→1 in startups and are comfortable with ambiguity.\n\nYou'll spend time with the solutions team and with pharmacies to understand how their workflows actually differ. No healthcare background required.\n\nHow we work\nWe're a handful of people going all in on a problem we think is worth it, holding a high bar and shipping work that reaches real patients. It's intense, and it isn't for everyone. We want people who want to build something that matters, alongside others who care as much as they do. If that's you, we should talk.","description_format":"text","description_chars":3901,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Autonomous Driving","AI Agents"],"lifecycle":[{"event":"open","at":"2026-11-09T07:36:43Z"}],"visa":[],"liveness":{"score":77,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.853,"p_room":0.9,"age_days":14,"expected_fill_days":29,"reasons":["conf:2","win:mid"],"computed_at":"2026-11-10T01:39:10Z"},"pay":{"stated_usd_annual":215000,"is_top_pay":true},"html_url":"https://alion.io/job/sodalis-ai-senior-backend-engineer-application-platform","json_url":"https://alion.io/job/sodalis-ai-senior-backend-engineer-application-platform.json","meta":{"generated_at":"2026-11-10T01:39:10Z","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":3821,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":4475109},"rest":"https://alion.io/mcp/rest/get_company?id=4475109"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsodalis-ai-senior-backend-engineer-application-platform"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fsodalis-ai-senior-backend-engineer-application-platform"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fsodalis-ai-senior-backend-engineer-application-platform"},{"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/sodalis-ai-senior-backend-engineer-application-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsodalis-ai-senior-backend-engineer-application-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3955337}},{"tool":"search_jobs","arguments":{"company":"sodalis.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3955337},"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.
