Prior Healthcare, life sciences, or other regulated industry experience preferred. Technical Skills Strong proficiency in a statically typed, object-oriented or systems language; experience with TypeScript and Node.js is preferred, and candidates should be comfortable moving into that stack (Fastify, oRPC experience a plus)Frontend experience with modern component-based frameworks and dependency injection patterns (Vue preferred; React or Angular experience transfers well)Strong SQL and working knowledge of relational database design; experience with PostgreSQL and an ORM or query-builder (Prisma preferred) is a plusExperience designing and consuming REST APIs; exposure to event-driven patterns is a plusExperience with at least one major cloud platform (Azure preferred)Comfort with Git-based workflows, CI/CD, and modern development practices; experience with containerization and container runtimes (Docker)Experience with infrastructure as code tooling (Terraform or OpenTofu preferred) and applying common cloud best practices around security, scalability, and cost management Soft Skills Strong analytical and problem-solving skills grounded in first-principles reasoningClear, confident communication across engineering, product, and operations - in writing, in design artifacts, and in conversationAbility to work independently with sound judgment while actively contributing to a collaborative, open team environmentAttention to detail and pride in delivering reliable, well-tested work Other Qualifications Working understanding of healthcare data privacy, HIPAA, and PHI handling Familiarity with FHIR (HL7 R4) or other healthcare integration patterns is a plus Familiarity with Model Context Protocol (MCP) is a plus Familiarity with Claude and the Claude ecosystem of tools and features is a plus Differentiating Background You lead with first principles - you know which engineering principles and patterns apply to a given problem, and more importantly, when they don't. You know the difference between applying a principle and hiding behind one. That same discernment extends to AI - you value your autonomy and judgment in a world of AI sycophancy, reaching for it when it eliminates real drag and ruling it out when it doesn't.You prefer as little magic as possible - dependencies are wired explicitly, ownership is clear, and nothing happens behind the scenes that you didn't put there. You prefer explicit over implicit, interfaces at the boundary over deep inheritance, and errors as first-class values - typed, explicit, and handled at the right layer.You communicate with clarity and conviction - whether through an RFC, a design document, an architecture diagram, a coding agent spec, or a message in chat. You don't just have opinions; you can write them down and defend them.You multiply the people around you. You mentor through code review, in chat, and in person - with the company, the team, the individual, and yourself in mind. You keep conversations open and push back on silos.
