About the role

  • Today, AI has made account compromise the #1 cybercrime https://www.ic3.gov/AnnualReport/Reports/2024_IC3Report.pdf.

Responsibilities

  • Ownership is everything here. You'll have deep knowledge across the stack and own large parts of the platform - from our AI detection pipeline to the product surfaces that MSPs and security teams rely on every day.

  • Drive product quality end to end. Take problems from raw customer insight through to shipped, production features. You care about the full loop, not just your slice.
  • Raise the technical bar. As a senior voice on a lean team, your instincts and opinions shape how we build. You'll establish patterns, push for correctness, and raise the quality of everything around you.
