About the Role

Focus on Sailboxes, our cost-efficient CPU sandbox for long-horizon agents. You’ll be one of the first engineers on a rapidly growing product-line and write code at every part of the agent runtime, from low-level performance work on our custom networking stack to building large scale systems that maximize our efficiency.

Responsibilities

  • Extract maximum performance from the platform by digging into the custom FirecrackerVM fork.
  • Model historic usage patterns and implement scheduling algorithms to maximize fleet utilization and autoscale intelligently while minimizing latency.
  • Design and implement highly-available distributed systems to handle millions of operations per second.
  • Build deep monitoring tooling and features to make Sailboxes a delightful experience for humans and agents.
  • Own future product directions for Sailboxes, including Windows/Mac sandboxes and high-efficiency storage.

Requirements

  • Strong distributed systems fundamentals, including concurrency, networking, databases, and performance engineering.
  • Experience building and maintaining software for large-scale production distributed systems.
  • Experience with cloud infrastructure (GCP, AWS, Azure), container orchestration, and/or multi-cloud networking.
  • A product-focused approach to platform work, with a commitment to building robust, scalable, and ergonomic solutions.
  • Experience with FirecrackerVMs is a plus.
