About The Role

We are seeking a Staff Software Engineer to accelerate the reliability and velocity of Sully.ai’s core product. You will take ownership of critical services and UI components end-to-end, setting engineering standards, shaping rituals, and applying SRE practices to ensure measurable performance. This role combines deep technical execution with leadership — guiding reliability practices, strengthening pipelines, and enabling the team to ship faster with confidence.

Key Responsibilities

• Own a product slice end-to-end (service + UI) with defined SLOs, dashboards, and on-call practices modeled on DORA/SRE standards.
• Refactor high-churn pipelines (e.g., transcription → JSON notes, EHR writebacks) behind stable contracts and automated tests.
• Lead engineering rituals (weekly plan → ship → measure cadence, observability reviews, post-deploy metrics).
• Improve clinical reliability and latency with profiling, caching, and schema/contract hardening.
• Mentor engineers and set quality guardrails for velocity, reliability, and maintainability.

Hard Requirements

• Proven experience operating production services with measurable reliability (SLO/SLA, error budgets) and CI/CD practices.
• Strong technical depth in Python and TypeScript; able to operate across APIs, data pipelines, and UI.
• Experience driving systemic reliability and velocity improvements across teams.
• Bias to action and comfort in ambiguous, founder-style environments.

Nice-to-Have

• Healthcare/EHR integration experience (FHIR, HL7, bidirectional sync).
• Experience leading small teams or cross-functional initiatives.
• Background with OpenTelemetry, advanced observability, or scaling in regulated industries.

First-Month Focus

• Take ownership of a core product service and establish clear SLOs and dashboards.
• Audit reliability pain points (audio→note, EHR sync paths, agent interfaces) and propose immediate refactors.
• Implement weekly “plan → ship → measure” engineering cadence with metrics visible to the team.

Success OKRs (90 Days)

• Halve error rates on at least one high-churn pipeline via tracing, contracts, and CI/CD guardrails.
• Cut latency of core product workflows (30–50%) under clinical load.
• Establish team-wide observability and engineering rituals (on-call, post-deploy metrics, lead time tracking).

Culture Fit

• Persistent, driven problem solver
• Willing to push back on leadership to defend quality/timelines
• Thrives in high-ambiguity, fast-paced startup environments
