What You'll Do

  • Own Render's core network infrastructure across multiple data centers and cloud providers. 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.
  • Investigate complex networking issues across the stack, from the kernel and data plane to distributed systems and edge networking.
  • 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. 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.
