Senior Software Engineer, Agentic Coding RL Environments - AI Trainer

• Professional software engineering experience shipping real, scaled production systems
• Expertise in at least one common tech stack (TypeScript, Python, Ruby, PHP, Java, Rust, Go, or C++)
• Strong judgment about what “good code” and a “meaningful model failure” look like
• Comfort working independently, and giving direct, code-review-style feedback
• Availability for a meaningful commitment (most contributors work 20 to 40+ hours per week)

Note: You do not need prior AI or ML experience. Strong engineering judgment and attention to detail matter most. What makes this different

• No managers, 1:1s, OKR ceremonies, or Jira backlog grooming, * Coding capability screen (replaces a multi-round interview loop)
• ID verification
• Background check
• Paid first real task. Do well, and you’re on the team.

Surge AI partners with the world’s leading AI labs to build the benchmarks and RL environments that train and evaluate frontier models. Most benchmarks cut corners because expert humans are expensive. Our model is the opposite: we pay experts enough that we don’t have to.
