Outpace AI-driven attacks. Unify Digital Risk Protection, Human Risk Management, and Email Security to stop digital threats before they scale, empower your teams to lead your defense, and scale your SOC with agentic AI. Backed by Bessemer and a16z.
About the role
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.
What they're looking for
- Bring deep practitioner judgment from one or more of detection engineering, SOC/IR, threat intelligence/OSINT, or email/messaging security, range across multiple areas is a major plus
- Take messy detection failures from “something’s off” to root cause — prove what matters in the data and turn FP/FN cases into durable fixes
- Think like both attacker and defender across phishing, BEC, impersonation, credential theft, ATO, and evolving social-engineering TTPs
- Turn expert judgment into detection logic, evals, tests, requirements, and systems that scale beyond a single investigation or customer
- Thrive at the intersection of security, AI, product, and customers — challenge assumptions, use coding/AI agents aggressively, and move fast through ambiguity
