Design and build the service mesh infrastructure that enables communication across Roblox’s hybrid Kubernetes and Nomad environments, supporting billions of daily requests.

Drive the integration of service mesh with Kubernetes, ensuring reliable sidecar injection, mTLS, traffic policies, and observability for production workloads.

Build the networking foundation for Cloud Bursting, enabling Roblox’s top services to transparently burst from on-prem data centers to the cloud, with service discovery, traffic management, and locality-aware routing across environments.

Partner with internal application teams to understand their connectivity pain points, ensuring the service mesh provides a frictionless 'paved road' for thousands of developers

Collaborate with the Gateway and CNI teams to deliver a unified, multi-cluster service fabric that abstracts cluster and regional boundaries from application developers.

Serve as a primary escalation point for complex service mesh issues, troubleshooting across Envoy sidecars, Istio control plane, and the underlying network stack.

Act as a senior voice on the team, mentoring junior engineers and promoting best practices in testing, deployment, and reliability engineering.

A professional with 3+ years of experience in distributed systems, with strong expertise in service mesh technologies (Istio, Envoy, Consul, or Linkerd). You understand the tradeoffs of sidecar-based architectures at scale.

Deeply knowledgeable of service mesh concepts: traffic management, service discovery, mTLS, observability, and routing policies.

Experienced running Kubernetes in production and familiar with the K8s networking model.

Comfortable working with Envoy proxy internals, xDS APIs, and control plane architectures.

Excellent at designing large-scale distributed systems that span multiple clusters, regions, and runtime environments.
