Job summary

Fly.io is seeking a distributed systems engineer to operate and advance the proxy and routing layer behind a global container platform. You will focus on absorbing fast state churn from autonomous workloads while serving traditional traffic through a single high-throughput edge proxy and data store.

This fully remote role suits engineers who enjoy systems-level Rust and large-scale networking. Responsibilities include building a Rust-based reverse proxy for a global Anycast network, evolving the

Qualifications

• Production experience writing systems-level Rust for networking or similar high-performance services.
• Strong grasp of TCP/IP, TLS, HTTP, and modern load-balancing techniques.
• Comfort with operating systems internals relevant to fast, concurrent network programs.
• Familiarity with distributed systems spanning global infrastructure.
• Ability to reason about concurrency, state, and failure modes in high-throughput environments.

Responsibilities

• Design, build, and maintain a Rust-based reverse proxy that fronts a global Anycast network.
• Evolve the routing data plane to handle rapid lifecycle changes from short-lived workloads.
• Sustain long-lived stateful sessions alongside bursty traffic on the same infrastructure.
• Operate and harden the shared routing database that apps and orchestration depend on.
• Partner with the Go-based orchestration team on provisioning and lifecycle reliability.
• Improve observability, latency, and failure isolation across edge and load-balancing stack.
