AI Infrastructure Engineer, Sandbox Platform

The shape of it

In the posting’s own words

As a Software Engineer on the AI Infrastructure team, you'll help build and evolve our agent sandboxing platform — the secure, high-performance code execution layer powering our agentic workflows, deployed across both internal and customer-managed environments. This is a role for someone who cares as much about the experience of the engineers and researchers using this system as they do about the kernel internals underneath it.

What it asks for · 7

• 4+ years of experience building high-performance systems software, with meaningful time spent maintaining libraries, SDKs, or developer-facing APIs
• Experience with containerisation and virtualisation technologies (e.g., Docker, Firecracker, gVisor, QEMU, Kata Containers)
• Proficiency in a systems programming language such as Go, Rust, or C/C++
• A track record of obsessing over developer experience — API design, error propagation, documentation, and the small details that make a library feel well-crafted
• Strong debugging skills and the ability to navigate performance/security tradeoffs in production systems
• Comfort with ambiguity, and the ability to context-switch between reactive incident work and proactive product development
• Familiarity with LLM agents and agent frameworks (e.g., OpenHands, Agent2Agent, MCP)

Also a plus

• Experience as a founder or early engineer at an infrastructure-focused startup, owning a product end-to-end
• Familiarity with LLM agents and agent frameworks (e.g., OpenHands, Agent2Agent, MCP)
• Experience running secure workloads in multi-tenant or untrusted environments (e.g., FaaS, CI sandboxes, remote notebooks)
• Exposure to snapshotting and restore techniques (e.g., CRIU, VM snapshots, overlays)
• Open-source contributions to systems or developer-tools projects
• History of on-call/incident response for production systems
