About the team

The Predict team builds Alloy's real-time machine learning systems at scale. Our immediate focus is on fraud detection, where we believe machine learning can simplify and accelerate decision-making in ways traditional rule-based systems can't. Managing rules and policies to detect fraud is complex and constantly evolving; we use ML to make it smarter, faster, and more adaptive. Our approach is identity-centric, combining signals from a wide range of data sources to build a comprehensive understanding of risk.

You will work on advancing our core models while also partnering directly with customers to drive strong outcomes from fraud studies.

Alloy operates in a hybrid work environment. We look to foster collaboration and community by having our local employees onsite three days a week.
