About the role

About the Role

As the founding machine learning engineer at an early-stage AI company, you will build the ML function from the ground up. You will shape post-training and agent systems, set technical priorities, and help grow the team.

What You'll Do

  • Structure, filter, and score experimental trajectories for training data pipelines.
  • Design and implement evaluations and benchmarks for model reasoning, planning, and experimental progress.
  • Build reliable agent environments, tool interfaces, observability systems, and replay infrastructure.
  • Establish validation and provenance tracking for trajectory and data quality.
  • Set ML roadmap priorities across systems, experiments, and hiring, and guide the team's technical direction as it grows.

What We're Looking For

  • At least 3 years of machine learning engineering experience building or delivering production ML systems, with 3 to 8 years of overall relevant experience preferred.
  • Strong Python and systems-level programming skills, with production software engineering experience.
  • Hands-on experience with post-training ML, including data pipelines for structuring, filtering, and scoring training data.
  • Experience designing and implementing model evaluation frameworks and benchmarks.
  • Understanding of trajectories, reward structures, tool use, and agent environment design; experience with reinforcement learning algorithms and training systems is valuable.
  • Experience building agent environments, replay and debugging tools, data validation, provenance tracking, or ML pipeline observability is a plus.
  • Background in frontier AI research, scaled post-training or evaluation teams, or production agent systems is beneficial.

Compensation & Benefits

Annual salary range: $100,000 to $250,000 USD. Visa sponsorship is not available.
