Senior Software Engineer (Infrastructure)

• Courier Health is at an inflection point
• We exist to get patients faster, better access to life-saving therapies, and every one of those patients depends on infrastructure that is reliable, secure, and ready to scale
• The platform our engineers build on determines how quickly we can ship for our customers and how quickly patients feel it
• This role owns that
• You’ll design, deploy, and evolve our serverless-first AWS platform (Lambda, Step Functions, EventBridge, AppSync, and Aurora) along with the multi-account architecture, CI/CD pipelines, and guardrails that let every engineer move fast and ship with confidence
• It’s a rare combination: deep technical ownership at an early-stage company, in a domain where the stakes are real
• If you’re motivated by the opportunity to have an outsized impact on not just your company, but the healthcare industry at large, this is the role
• A serverless platform that scales with our growth. Lambda, Step Functions, EventBridge, AppSync, and Aurora are the core of what you’ll operate and evolve. You’ll keep it fast, reliable, and secure as our customer base and data volumes grow and provide the architectural guidance that helps teams build systems worthy of it
• Guardrails that make the right thing the easy thing. You’ll own our AWS multi-account architecture: account hierarchy, Service Control Policies, and IAM Identity Center. You’ll build and maintain the CI/CD pipelines and broader developer platform that make compliant-by-default the path of least resistance for every engineer on the team
• Observability and security we can stake the mission on. We work in healthcare so system health isn’t optional. You’ll implement and manage the monitoring and alerting that keep us ahead of problems, and proactively identify and address security vulnerabilities and infrastructure risk with an automation-first mindset that scales hardening without slowing delivery
• The engineering operations that make the whole team faster. You’ll continuously improve our day-to-day engineering operations, select and deploy the tools that keep our roadmap on track, build the integrations that bridge our backend services with our infrastructure layer, and establish the infrastructure standards that will scale with the company while collaborating across teams to unblock technical challenges wherever they show up
