Software Engineer, Network Infrastructure - Render

About Render

At Render, we’re building the modern cloud platform for developers creating AI-native, full-stack, multi-service applications. Our mission is to eliminate the tradeoff between the power of hyperscalers and the simplicity of developer-friendly platforms.

About the Role

Render builds and operates our own networking stack end-to-end. We are looking for engineers with deep specialization in network infrastructure, particularly with experience in edge/ingress networking and Kubernetes networking internals.

What You'll Do

• 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 the kernel and data plane to distributed systems.
• Drive performance and reliability improvements through systematic profiling and tuning.
• Partner with cross-functional teams to ensure a stable, predictable, and secure platform.
• Participate in our on-call rotation and incident response processes.

What We're Looking For

• 6+ years of experience building and operating large-scale networking or infrastructure systems.
• Proficiency with Kubernetes networking internals (e.g., kube-proxy, CNI plugins, service routing).
• Experience with Linux networking internals (e.g., routing, netfilter/iptables/nftables, conntrack) in production.
• Experience building and operating traffic routing systems (e.g., load balancers, ingress, proxies) at scale.
• Strong experience designing, debugging, and operating distributed systems.
• Ability to plan and execute high-risk changes with minimal downtime.

Nice-to-haves

• Experience with eBPF or advanced Linux kernel networking.
• Experience developing systems in Go or similar languages interacting with low-level OS/networking primitives.

Benefits

• 4 weeks of paid vacation.
• 14 weeks of fully paid parental leave.
• 100% employer-paid medical coverage; 99% dental and vision.
• Long-term disability, life insurance, and 401K plans.
• Monthly lifestyle stipend for wellness, mental health, and hobbies.
• Monthly cell phone and internet subsidy.
• Continuous learning benefits and home office stipends.
