About the Role
Running untrusted code and workloads safely, at scale, with solid isolation and data-security guarantees, is a hard and increasingly important problem in AI infrastructure. As a Sandbox Engineer, you'll build the isolated execution environments that make that possible.

What You'll Do
• Build and maintain container and microVM-based sandboxing for customer code and SQL execution
• Implement syscall filtering and container security hardening
• Support strong multi-tenant isolation guarantees for concurrent customer workloads
• Partner with our security function on data-egress monitoring and isolation requirements
• Continuously test and harden the platform's resistance to sandbox escapes What You'll Bring
• 5+ years of experience in systems, security,



or infrastructure engineering
• Strong experience with container or microVM technologies (Docker, Firecracker, gVisor, or similar)
• Solid operating-systems and security fundamentals, including syscall-level filtering
• Proficiency in Rust, Go, or C++
• A security-first mindset when designing multi-tenant systems Education B.
Tech in Computer Science, ideally with coursework in operating systems or security. Nice to Have
• A security engineering background (malware sandboxing, endpoint security) — this transfers directly to this role's isolation challenges
• Experience running multi-tenant infrastructure at scale
