Software Engineer, Network Infrastructure
Design, build, and operate Render's core networking stack across data centers and clouds, focusing on Kubernetes and Linux internals, traffic routing, and hybrid connectivity at scale.
About the job
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.
