About this role

About the company

Our client is a cybersecurity company.

The role

Raydar is recruiting for this role on behalf of our client. Own the design, training and production deployment of machine learning systems behind a core detection capability. Partner closely with technical leadership and help set engineering standards on a small, fast-moving team.

What you'll do

  • Design and build machine learning models that flag suspicious activity as it happens.

  • Take models from research into production and measure how they behave at scale in a live environment.

  • Architect systems that can absorb significant growth in data volume and traffic.

  • Talk with customers to understand the threats they face and uncover new signals that strengthen detection.

  • Set technical patterns, push for correctness and raise the quality bar across the team.

  • Own systems end to end, from data pipelines through serving and infrastructure.

  • Requirements

  • What we're looking for

  • 4+ years of machine learning engineering experience, including shipping models to production at scale.

  • A solid mathematical grounding, including statistics, linear algebra and applied modeling of anomalous behavior.

  • Experience training and deploying models, with good judgment about which approach fits a problem and where its limits lie.

  • Strong engineering fundamentals, including clean production-grade Python and end-to-end system ownership.

  • Hands-on background with low-latency data processing and scalable storage and compute systems.

  • High agency: you scope your own work, propose solutions and execute without direction.

  • Fast learner who ships quickly and is comfortable in a small, high-autonomy team.

  • Pride in craft and in building things that hold up over time.

  • Bonus points

  • Background in high-stakes domains such as quantitative finance or fraud detection.

  • Experience shipping production machine learning at an early-stage company or on an ML infrastructure team.

  • Degree in computer science, math or a quantitative field.

  • First-author publication at a leading machine learning conference.

  • Benefits

  • Compensation and benefits

  • Base salary: USD 250,000 to 300,000 per year

  • Equity

  • Health, dental and vision coverage
