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.\nWhat you'll do\n- Design and build machine learning models that flag suspicious activity as it happens.\n- Take models from research into production and measure how they behave at scale in a live environment.\n- Architect systems that can absorb significant growth in data volume and traffic.\n- Talk with customers to understand the threats they face and uncover new signals that strengthen detection.\n- Set technical patterns, push for correctness and raise the quality bar across the team.\n- Own systems end to end, from data pipelines through serving and infrastructure.\nRequirements\nWhat we're looking for\n- 4+ years of machine learning engineering experience, including shipping models to production at scale.\n- A solid mathematical grounding, including statistics, linear algebra and applied modeling of anomalous behavior.\n- Experience training and deploying models, with good judgment about which approach fits a problem and where its limits lie.\n- Strong engineering fundamentals, including clean production-grade Python and end-to-end system ownership.\n- Hands-on background with low-latency data processing and scalable storage and compute systems.\n- High agency: you scope your own work, propose solutions and execute without direction.\n- Fast learner who ships quickly and is comfortable in a small, high-autonomy team.\n- Pride in craft and in building things that hold up over time.\nBonus points\n- Background in high-stakes domains such as quantitative finance or fraud detection.\n- Experience shipping production machine learning at an early-stage company or on an ML infrastructure team.\n- Degree in computer science, math or a quantitative field.\n- First-author publication at a leading machine learning conference.\nBenefits\nCompensation and benefits\n- Base salary: USD 250,000 to 300,000 per year\n- Equity\n- Health, dental and vision coverage\n- Retirement plan\n- Commission\nLocation and work model\n- San Francisco, CA, United States\n- On-site, 5 days per week in office\n-
