In the posting’s own words

As a Staff Software Engineer, RL Environments, you'll own the technical foundation for how Scale builds, runs, verifies, and delivers RL environments at scale.

What it asks for · 7

  • 8+ years of software engineering experience with strong fundamentals in distributed systems, system design, data structures, and algorithms.
  • Strong Python skills and a track record of shipping production software; comfort in at least one other part of the stack (TypeScript/React, Go, Rust, or similar).
  • Deep experience with containerization and sandboxed execution, including Docker, VMs, gVisor/Firecracker, Kubernetes, or equivalent.
  • Experience building or operating high-throughput backend systems: orchestration, job scheduling, queuing, and large-scale data pipelines.
  • Hands-on experience building with LLMs including agent loops, tool calling, MCP, or eval harnesses, and enough intuition about model behavior to reason about what a training signal actually teaches.
  • Demonstrated ability to own ambiguous, undefined problems end to end and drive them to a shipped system.
  • Excellent written and verbal communication; ability to align engineers, researchers, and non-engineering partners on a technical direction.

How this page was made

An automated read of a public job posting, fetched September 2, 2026 and last changed by Scale AI on September 2, 2026. Every list above is pulled from the posting’s own sentences — nothing rewritten, nothing added, no judgment about the role or the company. Counts and seniority are read off the text by rule, so they can be wrong where the posting is unusual. The original is the only thing that binds. Openings close without warning; check the source before spending an evening on it.
