## About the Role

* A Track Record of Scaling MongoDB: You've redesigned a shard key, rebalanced chunks, or re-architected zone placement on a cluster that outgrew its original design, and you know the tradeoffs each option carries.
 * Battle-Tested SRE Experience: 5+ years of Site Reliability Engineering or Platform Engineering experience, with a track record of building and operating production infrastructure. You've been on call and resolved critical incidents.
 * Kubernetes Proficiency: Hands-on experience with Kubernetes and the CNCF ecosystem in production, including debugging multi-cluster networking issues.
 * Cloud Native Engineer: Experience with at least one major cloud provider (Azure, Google Cloud, or AWS - in that order of preference).
 * Infrastructure as Code Practitioner: Experience managing infrastructure with Terraform, OpenTofu, or Terragrunt, including reusable modules and state management at scale.
 * Observability Advocate: Hands-on experience with Prometheus and Grafana, including designing SLIs/SLOs and dashboards that help teams operate distributed systems.
 * Clear Communicator: Able to explain complex technical tradeoffs to both technical and non-technical audiences, and to document decisions so others can build on them.

What Will Make You Stand Out

 * MongoDB Atlas Depth: Experience with Atlas-specific capabilities such as Atlas Search, Provisioned Throughput, and the Atlas Admin API, or a track record of building custom tooling to close gaps in a platform's native monitoring.
 * Monorepo Experience: Familiarity with managing infrastructure for large monorepos, including build optimization and caching strategies. Bonus points if you've worked with Bazel, Nx, or similar tooling.
 * GitOps Practitioner: Hands-on experience implementing GitOps workflows with ArgoCD or Flux.
 * Security Mindset: Experience building secure infrastructure and understanding compliance requirements (SOC 2, GDPR) without sacrificing developer velocity.
 * Performance Optimization: Track record of optimizing infrastructure costs and performance.
 * GitHub Actions & Bazel: Experience with GitHub Actions for CI/CD pipelines, and familiarity with Bazel for monorepo builds.

## Description

* Own MongoDB and BigQuery Day 0 and Day 2 Operations: Take data infrastructure from first principles through steady state - initial cluster/dataset design and provisioning, then the ongoing work of monitoring, performance tuning, access management, and incident response once it's live.
 * Drive MongoDB Scaling Strategy: Design and execute sharding strategies for our largest collections - shard key selection, zone-based placement, chunk rebalancing - so the platform scales well past its current size without a painful re-architecture.
 * Instrument the Stack with Telemetry: Add metrics, logging, and tracing across different parts of our infrastructure - including MongoDB and BigQuery - so the team has the visibility to catch problems before they become incidents.
 * Build Cloud Infrastructure at Scale: Design, deploy, and operate infrastructure on Azure and Google Cloud that processes billions of security events daily.
 * Work Across Kubernetes & the CNCF Ecosystem: Operate resilient, self-healing infrastructure using Kubernetes and ArgoCD, and help architect multi-tenant clusters that keep customer workloads isolated.
 * Advance Infrastructure as Code: Build and maintain Terraform/OpenTofu modules that let the team provision infrastructure safely and consistently through GitOps workflows.
 * Collaborate Across Teams: Partner with Security, Backend, and Product Engineering so the platform's data layer keeps up with the rest of the product.
 * Iterate and Innovate: Ship infrastructure improvements weekly, balancing speed with reliability as the platform grows., * Hands-On MongoDB Experience, Day 0 and Day 2: 4+ years operating MongoDB (MongoDB Atlas included) in production - sharding, replica set design, index strategy, backup and restore - across the full lifecycle, from standing up a cluster to keeping it healthy at scale.
