The role This company runs a global tax automation platform, powering compliance for some of the largest digital businesses. Backed by leading VCs, they've raised significant capital and are reportedly crossing significant ARR. They solve a complex, real-time problem at scale, operating Kubernetes runtimes across multiple cloud providers. You'll join a core SRE team building the self-service platform that product engineers consume. This isn't a traditional "ops" role focused on manual tasks. Instead, you'll automate relentlessly, manage infrastructure as code, and treat developer experience as a first-class outcome. Your mission: enable every team to fully own and operate their services in production, reliably and uneventfully. The work Automate infrastructure as code for a self-service platform, ensuring a "git-first" approach. Evolve Kubernetes runtimes across multiple cloud providers, delivering real-time tax decisions at enterprise scale. Build internal tooling and strengthen observability (Grafana, Prometheus, Datadog) to empower product engineering teams. Define, improve, and enforce SLIs, SLOs, and SLAs for critical services, participating in on-call rotations. Automate Postgres and Elasticsearch platforms, enabling safe, self-service consumption for development teams. What You Bring You manage infrastructure with code (Terraform or equivalent) and enforce a "it doesn't exist if it's not in git" standard. Hands-on experience with Kubernetes operations at production scale, ideally across more than one cloud provider. Daily programming skills in at least one language, used to automate operational work, not perform it manually. Proven track record defining and improving SLIs, SLOs, and SLAs in a real environment, with on-call experience. A bias for simplicity over cleverness, and data over opinions in infrastructure decisions.
