Job summary

CoreWeave is seeking a Senior Engineer for the Cloud Platform API team to design and operate gateways that front the control plane. You will drive migrations to Envoy, own routing/TLS/mTLS, and define engineering standards across the gateway stack.

You will mentor engineers, lead post-mortems, and collaborate with multiple teams to ensure reliability and performance of a high-traffic, global platform. This role sits on a technical‑leadership track with potential for team leadership.

Qualifications

• Production experience writing Go.
• Deep experience with networking and traffic infrastructure: L4/L7 load balancing, reverse proxies (Envoy, HAProxy, or NGINX), or API gateways.
• Deep Kubernetes experience, ideally with the Gateway API or Ingress, operators and controllers, and running multiple clusters and the applications deployed across them.
• A strong grounding in TLS/mTLS and edge and authentication concerns, plus performance tuning of network-facing services.

Responsibilities

• Own the API and Kubernetes Gateways API stacks and their CRDs: routing, TLS/mTLS, rate limiting, and observability.
• Drive large-scale infrastructure migrations (for example, HAProxy → Envoy) across every zone with one audit-log shape and no customer-visible regression.
• Manage networking and traffic at scale: L4/L7 proxying, load balancing, global routing, live failover to healthy backends, encrypted transport, and performance tuning.
• Set technical direction across the gateway stack and define the engineering standards the team follows.
• Mentor senior and mid-level engineers, lead post-mortems, and act as a bridge across teams and to leadership.
