About this 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, connecting research with reliable production infrastructure.
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 to support trajectory and data quality.
- Set priorities for the ML roadmap, experiments, systems, and hiring.
- Guide the technical direction of the ML team as it grows.
WHAT WE'RE LOOKING FOR
- At least 3 years of professional machine learning engineering experience building or delivering production ML systems.
- Professional experience in post-training or model evaluations, including hands-on work structuring, filtering, and scoring training data.
- Production software engineering experience with Python and systems-level programming for ML infrastructure.
- Experience designing and implementing ML evaluation frameworks and benchmarks.
- Strong knowledge of trajectory data, reward structures, tool use, and agent decision-making.
- Experience building agent environments, replay and debugging tools, RL training systems, or data validation and observability infrastructure.
- Reinforcement learning implementation and tuning experience is valuable, as is experience in frontier AI research or scaled post-training and evaluation teams.
- Comfort owning priorities and working across research and production in an ambiguous environment.

About this listing
Published on Ashby under the board identifier Clera, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
