Desirable

• The Development Infrastructure (DevInfra) team sits within the SRE Platform Engineering organization and focuses on curating and improving the foundational tools and workflows that enable our engineers to develop, build, and ship infrastructure safely and efficiently
• Our remit includes managing our GitHub Actions self-hosted runners, Terraform workflows, Bazel build system, and Crossplane to enable scalable multi-cloud infrastructure provisioning through Kubernetes
• We support services deployed across AWS, GCP, and Azure
• DevInfra plays a central role in ensuring our infrastructure development experience is repeatable, testable, and fast, helping engineering teams operate efficiently and safely at scale
• We are looking for a Site Reliability Engineer to join the DevInfra team and help shape the systems and workflows that empower infrastructure developers at MongoDB
• You will play a key role in designing, implementing, and improving the systems that make it safe and easy to deliver infrastructure as code, build and test using Bazel (running on self-hosted GitHub Actions runners), and provision cloud infrastructure via Kubernetes using Crossplane
• This is a highly collaborative role – you’ll work closely with other Platform Engineering, Infrastructure Security and end user teams, contributing to both technical design and hands-on implementation
• Your work will directly influence the developer experience and the reliability of our cloud provisioning and infrastructure development workflows
• Contribute to core components of our Terraform and Bazel workflows
• Implement improvements to our infrastructure CI/CD and build pipelines
• Contribute to a roadmap that makes it easier for teams to safely onboard infrastructure changes and scale workflows
• Participate in our on-call rotation, focused on infrastructure tooling reliability supporting production services
