About the role

Research Engineer role at micro1 focusing on frontier Reinforcement Learning, developing novel environments, training pipelines, and evaluation systems to advance AI model capabilities. Remote, full-time position with compensation $400K - $800K per year.

Responsibilities

  • Architect self-contained RL environments that capture complex, real-world tasks, including reward functions, verifiers, and evaluation logic.
  • Design and scale episode pipelines and multi-component training processes (MCPs) to support reproducible experimentation.
  • Build automated data generation systems, leveraging synthetic data to accelerate training cycles without compromising quality.
  • Develop and integrate AI-driven evaluation and quality assurance systems for automated grading, validation, and feedback loops.
  • Fine-tune and optimize open-source RL models using internally generated datasets and custom training strategies.
  • Establish benchmarking frameworks to measure model capability, robustness, and data quality across tasks.
  • Contribute to the release and analysis of evaluations on internal and external benchmark platforms (e.g., micro1 benchmarks).

Qualifications

  • Deep experience in Reinforcement Learning, including environment design and training dynamics.
  • Strong track record of building and scaling RL systems, pipelines, or experimentation frameworks.
  • Proficient in automation and data generation, including synthetic data pipelines.
  • Familiar with automated evaluation systems, model validation, and quality assurance workflows.
  • Experienced in fine-tuning and evaluating open-source ML models.
  • Clear, concise communicator with strong technical writing skills.
  • Comfortable operating in fast-paced, research-driven, and highly collaborative environments.
