Software Engineer, Compute Infrastructure

What You'll Do

• Own Render's core compute infrastructure across multiple cloud providers, regions, and data centers. Shape how the compute platform evolves as the company rapidly scales.
• Design and build capabilities that give users greater performance and flexibility in how their services are built, deployed, perform, and stay available even when underlying resources go down.
• Investigate challenging cloud and compute issues across the stack, from the kernel and data plane to the Kubernetes cluster, control plane, and other orchestration mechanisms.
• Improve the performance and reliability of the infrastructure through systematic profiling, experimentation, and tuning.
• Partner with engineers across the company to build a platform that is stable, predictable, and secure.
• Participate in the on-call rotation. Help continuously improve how incidents are detected, responded to, and learned from.

What We're Looking For

• At least 7 years of experience building and operating large-scale platform or compute infrastructure.
• Deep expertise in operating, scaling, and enhancing Kubernetes clusters or similar resource/container orchestration systems.
• Experience developing in Go, Rust, or similar languages to develop custom infrastructure components, scheduling, controllers that apply business logic to resource management.
• Comfort going broad and deep in complex systems, making tradeoffs to improve performance and efficiency without sacrificing reliability.
• Strong experience designing, debugging, and operating distributed systems.
• Experience planning and executing rapid, high-risk upgrades and changes with minimal downtime to user services.

Nice-to-Haves

• Background in virtualization technologies like Firecracker, gVisor, Kata, or similar.
• Experience optimizing the performance of node, pod, and container spin-up times.
• Familiarity with eBPF, Linux kernel internals, resource management.
• Comfort securing and isolating workloads in multi-tenant execution environments.
