About the role

As Engineering Manager / Tech Lead for the Sandbox (platform or infrastructure) team at Together AI, you will lead and grow the team responsible for building the isolated, secure compute environments that power AI code execution across Together's platform. Together Sandbox provides the sandboxed execution layer that enables reinforcement learning workflows, LLM code interpreters, AI agents, and developer tooling to run safely and at scale. This is a hybrid leadership role - equal parts technical leadership and people management . You will own the technical direction of the team while also building a high-performing engineering culture.

You will inherit a team of 4 engineers (3 backend, 1 full-stack) and be responsible for hiring and onboarding 4 additional engineers to scale the team's capacity and capabilities. The Together Sandbox team builds and operates Together AI's sandbox infrastructure: isolated, ephemeral compute environments where AI-generated code can run safely. The product serves both external customers via the Together Sandbox SDK and internal Together use cases, including code interpretation and reinforcement learning. What the team builds: Sandbox infrastructure: Container orchestration, gVisor-based isolation, lifecycle management (create, pause, resume, terminate) SDKs: TypeScript and Python SDKs that give developers programmatic access to sandboxes Platform integration: Authentication, billing, usage dashboards, and admin tooling within Together's platform Developer experience: Documentation, templates, observability, and debugging tools Key technical areas : gVisor, container orchestration, Kubernetes, Elixir backend services, TypeScript/Python SDKs, cloud infrastructure (AWS), API design, and systems reliability.
