Responsibilities

  • Identify workflow bottlenecks across build, test, release, and local development and build tools that reduce measurable toil.
  • Create and maintain golden paths, including service templates, CLIs, libraries, and automation.
  • Design reusable CI pipelines and deployment workflows that are fast, safe, and easy for teams to adopt.
  • Improve build and test reliability through flake reduction, hermeticity, and caching while reducing cycle time.
  • Support progressive delivery patterns such as canary and blue-green deployments and safe rollback mechanisms.
  • Establish shared observability primitives, standards, and libraries for metrics, logs, and traces.
  • Partner with product engineers to improve SLOs, alerting hygiene, dashboards, and incident learnings.
  • Build and improve core platform capabilities that make services easier to run and scale.

Requirements

  • At least 4 years of production software development experience, with meaningful platform, developer tools, infrastructure, SRE, or release engineering experience.

  • Comfort with containers and modern cloud infrastructure, including Docker and Kubernetes or related tooling.
  • Demonstrated improvements to developer experience through outcomes such as faster builds, fewer flaky tests, safer deployments, or fewer incidents.
  • Strong cross-team collaboration and communication skills, including writing clear documentation and driving adoption.
  • Preferred: experience with monorepos, build systems, large-scale CI performance, internal platforms, service templates, paved-road deployments, self-serve environments, or developer portals.
  • Preferred: infrastructure-as-code experience such as Terraform and a security-minded approach to software supply-chain security, provenance, secrets, and least privilege.
