Reliability and security are foundational. The systems you build must be secure, observable, and resilient under real-world load. We organize engineering around product teams that serve members, employers, and partners. The Infrastructure team builds and operates the platform that enables them to ship reliably. What you will do Own infrastructure health, performance, and reliability across the stack. Make architectural decisions and improve how we build and operate. Design and evolve infrastructure using Terraform. Improve CI/CD, deployments, and developer workflows so teams ship faster. Strengthen security across access controls, vulnerability management, and dependencies. Identify and eliminate reliability risks before they impact customers. What we are looking for Experience operating production infrastructure, platform, DevOps, or SRE systems. A track record of owning critical systems end-to-end. Strong experience with PostgreSQL or comparable relational databases in production. Experience managing infrastructure as code using Terraform. Sound judgment across reliability, performance, and security tradeoffs. A bias toward automation and improving developer productivity.
