You'll build features that pharmacy and health system teams use every day to run compliance-critical work, not internal tools that only other engineers will ever see.This is a senior-level role with real scope. You'll be trusted to take a problem from a rough product idea to something live in production, and to make sound technical calls along the way without needing every decision reviewed.Why This Role?Real ownership, fast. We're past the earliest startup stage but still small enough that one engineer can define how a whole workflow works for hundreds of health systems.Problems that matter. Pharmacy and Health System teams are drowning in manual, compliance-critical work. What you ship directly changes how much of that work a human still has to do.AI as a daily tool, not a slogan. We expect you to use AI deliberately in how you build, and we're building AI into the product itself.Backing to build for the long term. Series B funding from investors including Bessemer Venture Partners, Notable Capital, and Danaher co-founder Mitchell Rales gives us the runway to invest in the engineering foundation, not just ship quick fixes.What You'll DoBuild and ship full-stack features end to end, from the database to the UI, for workflows like 340B compliance, intake, rebate management, and claims reconciliationPartner directly with product managers and pharmacy operations experts to understand what pharmacy teams actually need, not just what's in the ticketOwn what you ship: design it, build it, test it, deploy it, and support it in productionMake sound tradeoffs between speed and durability as Plenful scales its platform to serve more health systemsContribute to the technical foundation of the platform, including how AI is embedded into product workflowsUse AI tools deliberately as part of how you work, not just how you demoReview code, weigh in on design docs, and help raise the technical bar across the teamMinimum Qualifications7+ years of professional software engineering experience, working across the stackProficiency in JavaScript and TypeScript, with working proficiency in PythonA track record building customer-facing products, not primarily internal tooling or developer platformsComfort moving across layers of the stack instead of staying in oneExperience working in a fast-moving, high-growth environment where priorities shift as the product and customer base scaleStrong instincts for what "production-ready" means in a compliance-critical, enterprise healthcare contextClear communication with product, design, and non-technical stakeholdersLocation: Open to candidates based in San Francisco (hybrid, in-office Mondays and Wednesdays) or based in Chicago (remote).Preferred QualificationsExperience with Java or Ruby (if no experience with Python.)
