Sr. Threat Hunting Engineer

 If you love turning real-world attacker behavior into resilient detections that actually hold up in production, this role is built for you. As a  Senior Engineer, Threat Hunting, you’ll operate as a senior individual contributor within a Security Operations function—owning detection engineering direction, leading hypothesis-driven threat hunts, and partnering across teams to run adversary emulation that validates (and improves) detection and response readiness. You’ll help shape not just alerts, but  telemetry strategy, defensive architecture, and how the organization learns from incidents.

You’ll help shape not just alerts, but  telemetry strategy, defensive architecture, and how the organization learns from incidents.
 

What you’ll do (Responsibilities)

  • Own and mature enterprise detection engineering  end-to-end—setting standards, patterns, quality bars, and long-term technical direction across security telemetry and detections.
  • Build and continuously improve high-fidelity detections  across SIEM/EDR, identity, cloud, network, and SaaS environments—focused on scalability and resilience against evolving tradecraft.
  • Lead complex, hypothesis-driven threat hunts and adversary emulation exercises, partnering with internal stakeholders to validate real-world detection and response effectiveness.
  • Translate findings into durable improvements  (not one-off wins): new detections, improved telemetry, response playbook enhancements, and defensive/architectural changes; serve as technical lead during high-severity incidents.

What you’ll bring (Requirements)

  • 5–8+ years  in security operations, detection engineering, threat hunting, and/or offensive security with a track record of tackling ambiguous, cross-functional security problems.
  • Deep knowledge of  adversary behaviors and detection techniques  (e.g., mapping attacker tradecraft to practical detections across endpoint, identity, cloud, network, and SaaS).
  • Hands-on experience with  SIEM/EDR and large-scale log analytics, such as Google SecOps, Microsoft Defender XDR, CrowdStrike, and similar tooling.
  • Strong  scripting/automation capability  (and the communication skills to explain technical risk clearly to security/technology leaders and business stakeholders).

(Preferred)

  • Experience with  Google SecOps SIEM, Microsoft security stack, and/or Proofpoint email security
  • Windows/Linux administration background
  • Security certifications (e.g.,  CISSP, CASP  or related)
  • Bachelor’s degree in Cybersecurity/Computer Science (or equivalent practical experience)
Salary: $153,000-$169,400/year
