The posting

ABOUT THE ROLE

Join an AI research team as a Research Engineer, turning experimental code into production-ready systems. You will build the shared infrastructure and post-training pipelines that help research projects scale while preserving experimental integrity.

WHAT YOU'LL DO

- Turn research prototypes into tested, reusable data generation, training, and evaluation pipelines.

- Build distributed experiment infrastructure for data loading, checkpointing, and collecting agent interactions.

- Profile workloads and improve GPU utilization, memory efficiency, and data throughput.

- Develop tests, experiment tracking, and debugging tools while ensuring changes preserve research results.

- Work with researchers to translate ideas into robust, maintainable software.

WHAT WE'RE LOOKING FOR

- Strong Python skills and hands-on experience with PyTorch, JAX, or a comparable machine learning framework.

- Experience building and debugging software for model training, inference, or large-scale data processing.

- Understanding of machine learning experiments and how data, numerical precision, and implementation choices affect results.

- Sound software engineering practices, including testing, profiling, version control, and documentation.

- Distributed training or data processing experience with tools such as PyTorch distributed, DeepSpeed, or Ray is valuable.

- Familiarity with model-serving, machine learning, or experiment tracking tools is a plus; reinforcement learning systems and multimodal datasets are also useful.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
