Paxos The Security Engineer, Detection and Response at Paxos builds detections, hunts threats, and automates responses to protect cloud infrastructure, crypto systems, endpoints, and networks. The role includes running purple team exercises and improving detection coverage and operational efficiency.

Responsibilities

The Detection and Response Engineer at Paxos serves as a builder of the detections, hunts, and automations that protect our cloud infrastructure, crypto systems, endpoints, and network. You will write detections as code and automate response, and act as a purple teamer, emulating attacks alongside our Product Security teams to confirm our detections work. Our 24x7 SOC handles first-line triage, so your focus is the detection engineering, threat hunting, and validation that make our coverage effective. Strong hands-on investigation skills are expected, but they support this work rather than define it.
Detection Coverage & Quality: Ship production-grade detections as code with measurable signal improvements—reducing false positives and closing gaps identified in purple team exercises.
Validated Defenses: Run purple team exercises with other teams to confirm detection effectiveness and identify blind spots.
Threat Hunting Program: Execute proactive hunts based on threat intelligence and convert findings into new detections and documented IOCs/TTPs.
Operational Efficiency: Build automations to accelerate investigation and triage; create and maintain runbooks and incident write-ups that make response consistent and repeatable across the team.
Detection Stack: Identify gaps and integrate best-in-class tools that increase team effectiveness and visibility across endpoints, cloud, network, and signing systems.
