About this role

About the company

Our client is a software company.

The role

Raydar is recruiting for this role on behalf of our client. Develop and deploy bespoke machine learning models for a software product, owning the work from raw data preparation through to live operation. Collaborate with colleagues across functions to turn product ideas into shipped features, within a small, fast-moving, fully on-site team.

What you'll do

  • Create, fit and assess proprietary neural models and learned representations that power the product.

  • Take charge of the full data workflow, from sourcing and cleaning through to the model fitting framework.

  • Strengthen the tooling used to run experiments, track results and reproduce outcomes.

  • Move models from early prototype into live use, then watch their behavior and refine them based on real usage.

  • Work with product and other colleagues to convert needs into machine learning solutions and release new capabilities.

  • Write tidy, efficient Python and join in peer review, testing and troubleshooting.

  • Follow current research developments and introduce promising techniques to the team.

  • Requirements

  • What we're looking for

  • Around 4 or more years working as a machine learning engineer in industry, or comparable research experience.

  • A graduate degree in a quantitative field such as computer science, with solid grounding in machine learning.

  • A track record of designing neural networks from the ground up rather than only adapting pretrained ones.

  • Experience devising original modeling approaches instead of leaning on ready-made tools.

  • Working knowledge of PyTorch or a similar deep learning library.

  • Hands-on experience with large language models and transformer architectures.

  • Exposure to graph-based neural architectures.

  • Experience delivering machine learning in production settings, with a clear sense of production standards; this is not a purely academic role.

  • Advanced Python skills and the ability to produce dependable code on your own.

  • Comfort juggling several priorities in a fast-paced startup.

  • Sharp problem-solving, careful attention to detail, and strong communication and collaboration.

  • Bonus points

  • Familiarity with world models.

  • Prior work in scientific or physical-world areas such as robotics or simulation.

  • Experience with managed machine learning services or large cloud providers.

  • Backend development experience with a Python web framework and SQL.

  • Background in CAD or geometry-focused computing.

  • Benefits

  • Compensation and benefits

  • Base salary: USD 175,000 to 250,000 per year

  • Equity

  • Health, dental and vision coverage

  • Flexible time off

  • Professional development opportunities
