Applied Cyber, Email Security (Detection Engineering)

You’ll investigate the hardest email threats and detection failures, then turn what you learn into detections, evals, AI behavior, and product capabilities that scale across every Doppel customer. As our technology learns to handle today’s problems, you’ll move up the complexity curve to solve the next ones.

• Own detection problems end-to-end — from emerging TTP or FN → investigation → detection hypothesis → validation → production coverage → measurement.
• Use AI as a force multiplier – build evals, supervise model behavior, use coding agents aggressively, and automate repetitive investigative work.
• Partner with Product and Engineering on signals, detection logic, edge cases, and validation.
• Work with customers and GTM on detection gaps, real-world TTPs, and platform behavior.
• Turn tooling, threat-intelligence partnerships, and provider relationships into new signals and detection capabilities.
