The opportunity
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…
What you'll do
Design and build the sandboxing platform, client library, and API surface for: secure code execution across containerized and virtualized environments
Ensure strong isolation, security, and reproducibility of execution across user sessions and workloads
Optimise for cold-start latency, memory footprint, and resource utilisation at scale
Drive down error rates through systematic debugging, monitoring, and proactive fixes
Partner closely with internal teams using the platform to understand their: needs, debug issues, and build tooling that serves their use cases
Respond to incidents and production issues with urgency, conducting root: cause analysis and implementing preventive fixes
What they're looking for
- Help develop and maintain a product roadmap for sandboxing, balancing: immediate needs against long-term architectural investment
- Lead architecture reviews and own projects end-to-end, from design through: deployment, in fast-paced cross-functional settings
- + years of experience building high-performance systems software, with: meaningful time spent maintaining libraries, SDKs, or developer-facing APIs
- Deep understanding of Linux internals: process isolation, memory management, cgroups, namespaces, etc.
