Senior Site Reliability Engineer Fleet Management

Platform Engineering is the department within SRE that is responsible for a range of critical infrastructure and operational functions that support the broader engineering organization. Among these are our multi-cloud-provider Kubernetes infrastructure networking load balancing (including our public-facing edge and internal service mesh) and observability and alerting systems.

The Fleet Management team provides the core runtime environment that empowers our developers to build and ship products to delight our customers. We manage the end-to-end lifecycle of our Kubernetes fleet alongside the critical components that ensure cluster reliability and security (e.g. CoreDNS cert-manager and Gatekeeper). As our infrastructure scales to support new use cases and products we are spearheading a migration from Terraform-based Infrastructure as Code (IaC) to an Operator-driven lifecycle management model.

This role can be based out of our Austin Boston Los Angeles New York City Raleigh or San Francisco offices remotely in the United States region or our European office in Dublin.
