Senior Software Engineer, Agent Platform

About This Role

We're hiring a Senior Software Engineer to join the Agent Platform team and help shape the future of agentic computing by building the software stack that drives it.

The Agent Platform is the core infrastructure for hosting agents at scale: container builds, fast cold-starts, isolation of untrusted workloads, networking, observability, and the developer tooling that ties it all together. This is your chance to work on groundbreaking innovations in agentic computing, contributing to the platform that powers the next generation of voice and AI applications.

If you're eager to dig deep into systems, take real ownership over a fast-growing product area, and ship features developers depend on — we want to hear from you.

You'll Thrive Here If You:

• obsess over crafting code that is fast, reliable, and practical for the problem
• are known as the go-to person for tackling tough technical problems
• work hard and can build and ship fast
• can clearly explain complex technical concepts to other engineers
• are a fast learner, frequently picking up new languages and tools

What You'll Do

• Develop the core platform for hosting agents
• Build resilient systems to deploy agents across global data centers
• Create end-to-end tooling for seamless management of hosted agents
• Work across Go, Firecracker, Docker, Temporal, Kubernetes, and similar technologies
• Own significant portions of the platform end-to-end, from design through deployment and iteration

Who You Are

• Strong SWE/SDE/SRE background with deep backend experience
• Deeply competent in some of the technologies we use: Go, networking, Kubernetes, buildkitd/Docker/containerd
• Skilled in containerization platforms and capable of digging into low-level details to solve complex problems
• Experienced designing and maintaining production distributed systems
• Self-starter who can jump in, own portions of a project, and drive decisions

Nice to Have

• Experience running untrusted code in isolated environments (gVisor, Firecracker, or similar)
• Experience at companies offering serverless functions or container platforms (Fly.io, Cloudflare, AWS Lambda, GCP)
• Background in OCI/container internals — speeding boot times, snapshotter optimizations, image layering
• Experience with software-defined networking, anycast, BGP, or VPC integration for serverless workloads
