We're building a more trustworthy Internet. Come join us.

Foundation Engineering at Fastly is looking for a Site Reliability Engineer to join our Cloud and Container Services team. This role is focused on helping to scale and manage Fastly’s Kubernetes based platform for control plane services.

A successful candidate will help expand our platform feature set, support existing users and onboard new services, and drive efficiency while maintaining a secure platform.

What You'll Do

  • Design, build and operate infrastructure (cloud, Fastly datacenter) to enable reliable and rapid deployment, effective monitoring, and resilient operation in a large-scale Linux environment. The majority workloads are containerized but some are using native cloud services such as compute and storage
  • Diagnose and resolve performance and reliability issues across the stack: application, operating system, network, 3rd party services and APIs, including cross-application dependencies
  • Deploy and support complex 3rd party and internally developed applications
  • Write tools to automate maintenance and deployment of servers, services, and applications
  • Collaborate with internal users and continually evolve the platform and its operations using solid engineering practices

  • Experience with programming languages such as Go and Python. You can read code and reason about what it does. You can write code within an existing large code base such as adding features. You can create medium-sized programs from scratch such as custom kubernetes controllers, custom prometheus exporters, and building tooling to help manage infrastructure
  • Experience with infrastructure and configuration management tooling. You have used Terraform to manage infrastructure
  • Experience provisioning and managing users and resources with cloud providers such as AWS and GCP. You have provisioned users and accounts using both graphical user interfaces and infrastructure as code frameworks. You have experience provisioning components on public cloud and understand how they work together in creating a multi-tiered service. You have deployed and managed services built on top of public cloud components such as EC2, S3, and GKE
  • Experience with CI/CD and GitOps tooling. You can iterate infrastructure via pipelines through code changes. You have experience using Github including creating and reviewing pull requests
