Senior Platform Engineer: Secure, Scalable AI Runtime

Superserve Inc.; San Francisco (CA); Hybrid; USD 165,000 - 230,000; Full time

Job summary

Superserve Inc. in San Francisco is hiring a Platform Software Engineer (Senior/Staff) to scale the core runtime and define how untrusted AI agents execute safely at scale.

You’ll own end-to-end platform design—from low-level runtime primitives to distributed scheduling and production reliability. This high-ownership role involves building the agent runtime infrastructure (Firecracker, Rust, Go), enforcing security boundaries, and setting technical direction.

Qualifications

• Experience with distributed systems at scale.
• Strong systems background: concurrency, isolation, networking, performance.
• Experience with Go and/or Rust, or willingness to learn quickly.
• Deep intuition for security and reliability, not just features.

Responsibilities

• Design and build the agent runtime infrastructure (Firecracker, Rust, Go).
• Define and enforce security boundaries for running untrusted code.
• Architect and implement scheduling and orchestration systems (Kubernetes-level problems, without blindly copying Kubernetes).
• Implement a global scale distributed systems architecture across regions and bare metal providers.
• Own performance, isolation, and reliability at scale.
• Set technical direction and raise the bar for engineering across the company.
