Senior Software Engineer

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

• 5+ years building distributed backend systems in production
• Proficiency with Kotlin or Java and the Spring Boot ecosystem
• Experience designing event-driven systems (Kafka or equivalent)
• Hands-on experience with MongoDB, PostgreSQL, or comparable data stores
• Track record of leading technical work across a team - not just executing it
• Experience with cloud-native deployment (Azure, AWS, or GCP)

What would set you apart

• Deep familiarity with domain-driven design and bounded context modeling
• Exposure to LLM/AI integration or document processing pipelines
• Experience with healthcare interoperability standards (FHIR, HL7) or EMR integrations
• Background in high-throughput, low-latency service design at scale
• Experience with event sourcing, CQRS, or other advanced event-driven patterns
