- Shape how networking evolves as Render rapidly scales.
- Design and build customer-facing networking capabilities that give users greater flexibility in how their services connect, communicate, and how traffic is routed.

- Drive performance and reliability improvements through systematic profiling and tuning.
- Partner with engineers across the company to build a platform that is stable, predictable, and secure.
- Participate in our on-call rotation and help continuously improve how we detect, respond to, and learn from incidents.

## What We're Looking For
- At least 6 years of experience building and operating large-scale networking or infrastructure systems.
- Experience with Kubernetes networking internals (e.g. kube-proxy, CNI plugins, service routing) or similar container networking technology.
- Experience with Linux networking internals (e.g. routing, netfilter/iptables/nftables, conntrack) in production environments.
- Experience building and operating traffic routing systems (e.g. load balancers, ingress, proxies) at scale.
- Strong experience designing, debugging, and operating distributed systems.
- Experience planning and executing high-risk changes with minimal downtime.

## Nice-to-Haves
- Experience with data center or hybrid cloud networking (e.g. BGP, AWS Direct Connect, Arista/Juniper).
- Experience with eBPF or advanced Linux kernel networking.
- Experience developing systems in Go or similar languages that interact with low-level OS and networking primitives.
