Member of Technical Staff - Sandbox Platform

Role overview Build the distributed systems that let users launch secure, isolated sandboxes across bare-metal CPU and GPU machines. The work spans workload placement, machine-level execution, and the APIs and tools developers use to create and manage sandbox environments.

Responsibilities - Design a control plane that places sandbox workloads efficiently across compute workers. - Build node-level runtime services to start and supervise secure micro virtual machines. - Coordinate storage and networking as sandboxes move from assignment to ready execution. - Develop and evolve the sandbox APIs, SDK, and command-line interface. - Improve lifecycle speed, efficiency, and resilience to failures. - Help shape technical direction and engineering practices on a small team.

Requirements - Deep systems engineering experience relevant to distributed infrastructure and runtime environments. - Ability to build reliable services that span centralized control and node-level execution. - Strong ownership, from technical decisions through delivery and operation. - Customer focus and sound judgment in a fast-moving engineering environment.

Benefits and work setup - Full-time role based in San Francisco.
