Software Engineer - Platform (Senior/Staff)

Software Engineer, Platform (Senior/Staff)

San Francisco / Remote

At Superserve, our mission is to give builders the foundation to run intelligent software in production.

We’re building agent sandboxes—runtime infrastructure that is fast, durable, and secure by default. This is the layer that lets AI systems actually run in the real world.

We’re a small, globally distributed team based in San Francisco, backed by forward-thinking investors.

The Role

We’re looking for a platform engineer to scale the architecture and evolution of our core runtime.

This is not a typical backend role. You’ll define how untrusted AI agents execute safely, how systems scale under load, and how we meet security and compliance standards from first principles.

You’ll work directly with the founder and own the platform end-to-end: from low-level runtime design to distributed scheduling to production reliability.

What You’ll Own

• Design and build ouragent runtime infrastructure (Firecracker, Rust, Go)
• Define and enforcesecurity boundaries for running untrusted code
• Architect and implementscheduling and orchestration systems (Kubernetes-level problems, without blindly copying Kubernetes)
• Implement aglobal scale distributed systems architecture spanning across regions and bare metal server providers.
• Ownperformance, isolation, and reliability at scale
• Set technical direction and raise the bar for engineering across the company

What We’re Looking For

• You’ve built and operateddistributed systems or infrastructure at scale
• Strong systems background (concurrency, isolation, networking, performance)
• Experience withGo and/or Rust (or willingness to go deep quickly)
• Deep intuition forsecurity and reliability, not just features
• You care abouthow things fail, not just how they work
• You’ve taken systems from0 → 1 or 1 → scale
• You’re comfortable makinghigh-stakes architectural decisions with incomplete information

Bonus:

• Experience withFirecracker, microVMs, containers, or sandboxing
• Experience withKubernetes or building schedulers
• Deep expertise inreducing I/O latency and maximizing throughput for data-intensive applications

Why This Role Matters

AI agents are unreliable, unsafe, and hard to run in production today.

We’re fixing that.

This role is about building the foundation that makes intelligent systems actually usable in real-world environments—fast, secure, and dependable.

If we get this right, a whole new category of software becomes possible.

Working With Us

• Small, high-ownership team
• Work directly with the founder
• Real technical authority and decision-making power
• No layers, no committees—just building

Bar for This Role

This is ahigh-ownership, high-agency role.
We’re looking for someone who wants toown a critical layer of the stack, not just contribute to it.
