Resumo da oferta

Scale is seeking a Software Engineer for the AI Infrastructure team to advance our agent sandboxing platform, the secure, high-performance code execution layer behind our agentic workflows. You will work across internal and customer-managed environments to deliver fast, reliable APIs and a strong developer experience.

You will design and maintain sandboxing components, improve isolation, and optimise latency and resource use at scale, partnering with teams to debug issues and shape the roadmap.

Qualificações

• 4+ years building high-performance systems software.
• Deep Linux internals knowledge (process isolation, memory, cgroups, namespaces).
• Experience with containerisation/virtualisation tech.
• Strong focus on developer experience and API design.

Responsabilidades

• 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.
• 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.
