Responsibilities
- Design, build, and operate Roblox's Envoy-based application gateway fleet — the front door for billions of daily requests — owning L7 routing, authentication, rate limiting, and traffic policy end to end.
- Own the reliability and scale characteristics of the gateway: capacity and headroom modeling, failure isolation and blast-radius reduction, progressive delivery of config and code changes, and measurable reduction in edge-caused incidents.
- Partner with the internal networking and service teams to deliver one coherent traffic story from client to service, abstracting cluster and regional boundaries away from application developers.
- Serve as a primary escalation point for complex edge and gateway issues, debugging across Envoy configuration and internals, xDS control plane behavior, TLS termination, and the underlying network and load-balancing stack.
- Act as a senior voice on the team, mentoring junior engineers and promoting best practices in testing, deployment, and reliability engineering.
Requirements
- A professional with 3+ years of experience in distributed systems, with strong expertise in networking architecture and technologies (Envoy, Kubernetes). You understand the tradeoffs of sidecar-based microservice architectures at scale.
- Deeply knowledgeable of L7 networking concepts: routing and request transformation, TLS termination and certificate management, authentication and authorization, rate limiting, and load-balancing.
- 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.
- Fluent in Go, C/C++, or Rust.
- Experienced with on-call rotations and approach infrastructure with a “reliability-first” mindset.
Conditions
- Roles that are based in an office are onsite Tuesday, Wednesday, and Thursday, with optional presence on Monday and Friday (unless otherwise noted).
- All full-time employees are also eligible for equity compensation and for benefits.
