About The Position

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.

Excel at translating complex business and engineering requirements into actionable, phased technical roadmaps
Have a high level of empathy, responsibility, ownership, and accountability
Excellent verbal and written technical communication skills
