Senior Site Reliability Engineer, Development Infrastructure

**About MongoDB:** MongoDB is a global leader in providing a comprehensive, scalable, and automatically scalable document database service. Our mission is to empower innovators to create, transform, and disrupt industries by unleashing the power of software and data.

**About the Role:** We are seeking a Senior Site Reliability Engineer to join our Development Infrastructure team. Our 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.

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.

**Key Responsibilities:**
- Building and maintaining container images, OS packages, and infrastructure tooling
- Creating self-service Terraform workflows
- Handling cloud resource provisioning across AWS, GCP, and Azure
- Designing, implementing, and improving the systems that make it safe and easy to deliver infrastructure as code
- Building and maintaining Bazel build system and optimizing build performance, caching, and reproducibility
- Managing cloud infrastructure (AWS preferred) and familiarity with concepts like IAM, VPCs, OpenID Connect and CI/CD
- Ensuring infrastructure-as-code is tested, validated, and changes are gated safely
- Developing cross-cutting tooling and collaborating across multiple engineering teams
- Writing clear documentation and proactively sharing knowledge with others
- Taking ownership of core components of our Terraform and Bazel workflows
- Proposing and implementing improvements to our infrastructure CI/CD and build pipelines
- Contributing to a roadmap that makes it easier for teams to safely onboard infrastructure changes and scale workflows
- Participating in our on-call rotation, focused on infrastructure tooling reliability supporting production services

**Requirements:**
- Have 6+ years of experience building and operating developer-facing infrastructure or platform tooling
- Be comfortable working with Terraform, and have experience managing Terraform workflows in a team or multi-environment setup
- Have hands-on experience with GitHub Actions, including writing reusable and maintainable workflows
- Have experience with Bazel (or similar build systems like Buck, Buck2 or Pants) and care about build performance, caching, and reproducibility
- Care deeply about developer experience, reducing cognitive load, and eliminating manual toil through automation
- Have experience with cloud infrastructure (AWS preferred) and familiarity with concepts like IAM, VPCs, OpenID Connect and CI/CD
- Have a solid foundation in infrastructure-as-code, including how to test, validate, and gate changes safely
- Be eager to work on cross-cutting tooling and collaborate across multiple engineering teams

**Bonus Points:**
- Experience with Crossplane or similar Kubernetes-native infrastructure provisioning tools
- Familiarity with or interest in Backstage or similar internal developer portals
- Previous contributions to building or maintaining internal developer platforms or tooling
- Experience working in multi-cloud environments
- An interest in onboarding and mentoring others in infrastructure best practices

**Compensation:** MongoDB’s base salary range for this role in the U.S. is $118,000—$231,000 USD. Additionally, this role is eligible for equity participation.

**Location:** This is a full-time, remote role for candidates based in the four continental US timezones. Prior familiarity with Bazel, Go, Terraform, Argo workflows and GitHub Actions would be helpful.
