Pelairo Inc. | Principal Engineer / Tech Lead | REMOTE (US) | Full-time
At Pelairo we're building the most intuitive and flexible Laboratory Information Management System (LIMS) on the market. "Manage the lab, not the LIMS!"
About the Role
We're looking for a hands-on Principal Engineer to lead the design and delivery of our backend—built on TypeScript + NestJS—and help our small team iterate quickly with confidence. You'll turn ambiguity into shippable slices, help set technical direction, and raise the bar on reliability, security, and speed.
Responsibilities
- Own the backend: spend meaningful time writing and reviewing production code.
- Architecture stewardship: keep the system coherent as we scale questionnaire-driven workflows and FHIR pipelines.
- Reliability & quality: Establish testing strategy (unit/integration/contract/E2E), migrations, rollouts (feature flags).
- Observability: Instrument tracing/metrics/logging, build dashboards/alerts; drive incident reviews.
- Raise the engineering bar: define and enforce code review policy, branching model, testing strategy, and CI/CD gates.
- Partner with Product & domain experts: translate healthcare workflows into configurable front-end modules; ensure back-end transforms to valid FHIR in Medplum.
Requirements
- 8+ years building production systems, including principal/staff scope in a startup or similar pace.
- Deep TypeScript + Node.js and expert-level NestJS in production.
- Track record leading cross-team projects and influencing architecture without heavy process.
- Product sense and crisp communication; comfortable owning ambiguous problems and shipping quickly with guardrails.
Bonuses
- FHIR/Medplum
- Healthcare data workflows
- HIPAA/SOC 2 experience
- Comfortable jumping into modern frontend (React/Next.js) when needed.
