Senior Software Engineer: Agentic Coding RL Environments

Senior Software Engineer: Agentic Coding RL Environments Frontier labs train and evaluate their coding agents on the RL environments and benchmarks you'll build. Make $200–300k+/year. Start the coding screen At a glance $100–$150+/hour Pay scales with your expertise 20-40+ hrs/week What most people do Guaranteed projects Fully remote Choose your own schedule The problem Coding agents are strong today in many ways, but frustratingly bad in others. They miss edge cases, make brittle changes, and often need close supervision from an experienced engineer. That's where you come in. To train better agents, we need the taste, judgment, and wisdom you've built over a career shipping scaled production systems. What you'll do You’ll build coding RL environments and benchmarks that test how agents perform on realistic software engineering tasks. That includes: Designing tasks based on real engineering work Reviewing and red-teaming model output Writing tests, rubrics, and success criteria Giving structured feedback that improves future models We provide the framework, tools, examples, and feedback you need to get started. You’re in charge of the when, where, and how you complete projects. Real-world impact During training Frontier labs train on the agentic coding RL environments you create. Before release Labs rely on expert SWEs to pressure-test models and surface failures. After release The industry uses the benchmarks you build to know which models are best. The environments you build are used to train, evaluate, and compare frontier coding models. See our research and benchmarks for examples. You’ll also develop a deep understanding of where coding agents succeed, where they fail, and how experienced engineers can use them effectively. Who we're looking for Professional software engineering experience shipping real, scaled production systems. Strong judgment about what "good code" and a "model failures" look like Comfort working independently , and giving technical feedbac
