About the Role
You’ll join our Ecosystem Experience team, responsible for connecting Semble to the wider healthcare ecosystem, including labs, pharmacies, partner APIs, webhooks, and Semble Connect. This role involves working closely with Product, Business, and external partners within a large TypeScript monorepo. We are a passionate and driven team that embraces new technologies, including AI, and values impact, collaboration, and a human touch.
Responsibilities
- Own problems end to end, from partner discovery through design, implementation, rollout, and production reliability.
- Operate with a high degree of autonomy and raise the technical bar for the team.
- Lead the design and delivery of integrations that move clinical and operational data safely between Semble and external systems, including REST/GraphQL APIs, webhooks, HL7, SFTP, and iPaaS/automation flows.
- Work across the stack in a Yarn/Nx TypeScript monorepo: React on the frontend, Node.js services and domain modules on the backend, GraphQL, and MongoDB.
- Translate ambiguous partner specs and product goals into clear technical designs, sequenced delivery plans, and clinically safe, testable solutions.
- Make sound architectural trade-offs and document decisions.
- Own production outcomes, including monitoring, alerting, incident diagnosis, root-cause analysis, and durable fixes.
- Improve reliability and operability, including failure handling, retries, idempotency, credentials/secrets, multi-tenant config, and safe rollouts.
- Contribute to Semble Connect and related automation.
- Set a high quality bar through design reviews, code reviews, automated tests, and CI/CD improvements.
- Mentor and unstick teammates, give clear feedback, and help junior engineers grow.
- Influence the Ecosystem Experience roadmap and technical standards, surfacing risks, proposing better approaches, and aligning stakeholders.
Requirements
- 5+ years' professional experience building production web applications with React and TypeScript, including substantial time operating as a senior / staff-of-one on complex features.
- Strong hands-on experience with Node.js backends and APIs (REST and/or GraphQL).
- Proven experience integrating with third-party systems — APIs, webhooks, auth flows, retries, idempotency, credentials/secrets.
- Ability to design systems, not just implement tickets.
- Comfort working in ambiguity — clarifying requirements, challenging weak specs, and driving decisions when information is incomplete.
- A production ownership mindset: debugging complex issues across services, reading logs/metrics traces, and preventing the same incident twice.
- Solid automated testing habits (unit/integration/e2e) and comfort with CI/CD.
- Experience with NoSQL databases (MongoDB or similar) and cloud-hosted applications (AWS preferred).
- Strong written and verbal communication.
- Collaborative leadership without needing formal authority: mentoring, reviewing thoughtfully, and aligning people around a plan.
- Security and privacy awareness appropriate for handling sensitive healthcare data.
- Comfort using AI coding tools to accelerate delivery without lowering the quality bar.
