Senior Software Engineer

Role description

Role Overview

The Runtime & GPU Systems team builds and operates secure, high-performance environments for multi-tenant Kubernetes platforms at scale. Our team sits at the intersection of container runtimes, lightweight virtualization, GPU infrastructure, and Linux systems engineering.

What You Will Do

Design, build, and evolve secure sandboxed runtime environments for Kubernetes workloads, focusing on runtime isolation, performance, and security. Develop GPU-aware sandboxing and scheduling strategies, optimize containerization and I/O performance for latency-sensitive workloads, and influence architectural decisions across Linux internals, container runtimes, virtualization layers, and GPU drivers.

Why It Might Be a Fit

We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams – even if you aren't a 100% skill or experience match. We support and encourage an entrepreneurial outlook and independent thinking. We foster an environment that encourages collaboration and enables the development of innovative solutions to complex problems.

Requirements

• 3+ years of experience in systems, platform, infrastructure, or production engineering at scale
• Strong hands-on experience with Kubernetes, container orchestration, and cloud-native architectures

• Practical experience with lightweight virtualization and sandboxing technologies (e.g., Kata Containers, gVisor, KubeVirt, QEMU)
• Experience supporting GPU-accelerated workloads in multi-tenant environments
• Proficient in systems-oriented programming (Go, C/C++, Rust, Bash) with strong Linux internals knowledge
• Skilled at diagnosing and resolving complex performance, reliability, or isolation issues across containers, VMs, and infrastructure
