Software Engineer, Network Infrastructure

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 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.
