About the Role
We are seeking a Senior Software Engineer to build and ship core product features that deliver measurable reliability and speed in clinical workflows. You will work across services, data, and UI to improve high-churn paths, reduce latency, and introduce automation — while modeling strong engineering rituals. This is a hands-on role where you’ll be expected to ship quickly, improve stability, and take ownership of end-to-end product experiences.

Key Responsibilities

• Build and ship new features across Python/TypeScript services, APIs, and UI.

• Improve stability in high-churn pipelines (transcription, JSON note generation, EHR writebacks).

• Reduce latency and regressions in clinical workloads through profiling, caching, and schema improvements.

• Contribute to team-wide engineering rituals: observability, CI/CD, weekly “plan → ship → measure.”

• Debug production issues and ensure fast recovery through tracing, alerts, and error budgets.

Hard Requirements

• Hands-on experience shipping production services with CI/CD and reliability practices.

• Strong Python and TypeScript skills; comfortable building across stack layers.

• Demonstrated track record of reducing latency, error rates, or lead time for changes.

• Comfortable working in ambiguous, fast-moving startup environments.

Nice-to-Have

• Experience with healthcare integrations (FHIR, HL7, EHR systems).

• Familiarity with observability tooling (OpenTelemetry, metrics pipelines).

• Background in performance optimization at scale.

First-Month Focus

• Ship at least one user-facing improvement across core services or UI.

• Implement tracing/alerts to stabilize a flaky pipeline and reduce failure rates.

• Adopt weekly “plan → ship → measure” cadence and track lead time for changes.

Success OKRs (90 Days)

• Reduce error rates in a core pipeline by 30–50%.

• Deliver measurable latency improvements (≥30%) in a high-volume workflow.

• Consistently ship features on a weekly cadence with visible post-deploy metrics.

Culture Fit

• Persistent, driven problem solver

• Willing to push back on leadership to defend quality/timelines

• Thrives in high-ambiguity, fast-paced startup environments
