## Description

Our engineering teams build the software that powers clinical care delivery at Oak Street Health - patient scheduling, care coordination, clinical records, and the integrations that connect our systems to health networks across the country. As a Sr Software Engineer, you'll own complex workstreams, drive technical decisions within your domain, and mentor the engineers around you. The work needs to be reliable, maintainable, and built to evolve - and in a healthcare environment, the quality of the design has direct clinical consequences.

What you'll do

 * Design and implement scalable microservices and APIs optimized for reliability and low latency
 * Own a domain or service area end-to-end, including its data model and integration contracts
 * Apply domain-driven design principles to define and enforce service boundaries
 * Build and evolve event-driven integrations using Kafka across service teams
 * Lead code reviews, set technical standards, and mentor junior and mid-level engineers
 * Partner with product and clinical stakeholders to refine requirements for high-impact initiatives
 * Hold the team accountable for test coverage, observability, and the production health of the services you own
