Reinforcement Learning Engineer

Responsibilities

• Own and ship an RL-driven trading agent using real capital to increase trading volume and user participation in a memecoin ecosystem
• Design reward functions and policies aligned with product goals while enforcing strict downside risk constraints
• Build evaluation and validation frameworks including simulation and offline analysis to minimize reliance on live sequential testing
• Safely transition an existing heuristic-based production system toward learning-based approaches
• Take end-to-end ownership and technical leadership as the sole RL expert, from data and modeling through deployment, monitoring, and safeguards

Requirements

• Proven experience putting an autonomous learning system into production that directly controlled capital, pricing, traffic, or resources
• Experience designing and enforcing hard risk limits such as capital caps, loss bounds, and circuit breakers in a live system
• Ability to build policy evaluation loops from scratch including simulators, replay, counterfactuals, and shadow deployments
• Ability to make and defend technical tradeoffs based on empirical results
• Experience operating as the single owner of a complex ML system in a small team environment
