We offer remote work as the default option in the United States in California, Colorado, Massachusetts, New York, New Jersey, Oregon, Pennsylvania, Texas, Utah and Washington, as well as in the UK, Singapore, and Canada - with plans to expand the locations we support in the future. Some roles are hybrid roles and will be listed as such. We have offices in San Mateo, CA and London, UK, and offer flex seating options for employees to work together in-person in NY and other areas.

About The Team: We have grown rapidly to where we are today, serving billions of HTTP requests daily. We achieved this scale by writing scale-sensitive components in languages like Rust and Go. We are seeking a Platform Engineer to join our team and help us scale by managing and developing the next generation of our infrastructure. While we currently maintain a 99.95% uptime, we are dedicated to sustaining this level of reliability as our product and business expand.

In this role, your core responsibility will be software engineering with a specialized focus on operations, infrastructure, and automation. You will develop the systems that power our product, enhance internal services, and provide architectural guidance to product teams to ensure optimal service operability. You will leverage Kubernetes to automate data center functions and create services that streamline database operations.

A major aspect of this position is gaining a deep enough understanding of our systems to move beyond manual intervention and build sophisticated software solutions that fully automate these processes.

What You'll Do:

  • Optimize and Elevate Performance: Identify bottlenecks in our systems and introduce cutting‑edge optimizations.
  • Forge Infrastructure as Code: Take the lead in setting up robust infrastructure and configuration‑as‑code with Kubernetes and Terraform.
  • Drive Observability and Monitoring: Establish and maintain a state‑of‑the‑art observability and monitoring stack.
  • Craft the Golden Path for CI/CD: Define and implement best practices for continuous integration and deployment.
  • Collaborate Across Teams: Work closely with engineering teams to architect highly scalable, observable services.
  • Be a Key Player in Incident Response: Join the on‑call rotation and play a crucial role in maintaining our systems' health.

What you'll bring:

  • At least 8 years of platform experience
  • Experience operating reliable production systems at scale
  • Knowledge of Linux systems internals
  • Desire and ability to automate tasks
  • Experience managing PostgreSQL for high‑scale throughput systems, or similar experience with other relevant SQL datastores.
  • Operational experience deploying and managing Kubernetes
  • Experience working with Cloud Providers (AWS/GCP/Azure)

It would be an added bonus if you have experience in any of the following:

  • Recently writing Go and/or Rust
  • Working with ScyllaDB
