Software Engineer, Network Infrastructure

Render is building a modern cloud platform for developers creating AI-native, full-stack, multi-service applications. The platform offers persistent compute, dynamic autoscaling, built-in orchestration, and observability, trusted by over 7 million developers. In February 2026, Render raised an additional $100M in Series C financing, bringing total funding to $260M.

Render builds and operates its own networking stack end-to-end, leveraging open source and industry-standard technologies. This role focuses on scaling and evolving traffic routing and load balancing systems, advancing Kubernetes and Linux networking components for large-scale, zero-downtime operation, and exploring networking for next-generation compute platforms.

• Own Render's core network infrastructure across multiple data centers and cloud providers.
• Design and build customer-facing networking capabilities for service connectivity and traffic routing.
• Investigate complex networking issues across the stack, from kernel and data plane to distributed systems and edge networking.
• Drive performance and reliability improvements through systematic profiling and tuning.
• Participate in on-call rotation and help improve incident detection and response.

• 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.

• 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.
