# Software Engineer

We are looking for AI Coding Experts to design and build complete, Dockerized Reinforcement Learning Environments (RLEs) used to evaluate and train AI coding agents. This is a hands-on engineering role focused on building realistic coding scenarios, reference solutions, verifiers, and test harnesses. It is not a prompt-writing or data-annotation role. Responsibilities: Design realistic, self-contained Dockerized coding scenarios from scratch. Build repository fixtures and clear task instructions for AI coding agents. Write working Python reference solutions that demonstrate the correct implementation. Develop deterministic verifiers, pytest harnesses, and evaluation logic. Review AI-agent trajectories to identify where and why an agent failed. Validate whether solutions represent genuine fixes rather than superficial patches. Revise and improve scenarios based on structured quality-review feedback. Ensure environments are reproducible, offline, and technically reliable. Requirements: Strong hands-on Python development skills. Experience writing real software, including reference solutions and automated tests. Strong proficiency with Docker and containerised development environm
