• Conduct threat modeling and proactive threat hunting to identify and mitigate emerging threats.

• Perform security audits on business applications and internal systems, identifying and closing visibility gaps.

• Engage in purple team exercises, simulating real-world attacks to assess and enhance detection and response capabilities.

• Work closely with the fraud, data science, and engineering teams to identify patterns of abuse, fraud, and other malicious activities.

• Develop custom automation and tooling to improve detection efficiency and reduce false positives.

• Provide incident response expertise, triaging and investigating security events to mitigate threats quickly.

Lead security awareness programs to improve organizational readiness and threat intelligence sharing.

Who You Are

• 7+ years of hands-on experience in Detection Engineering, Threat Hunting, Security Operations, or a related field.

• Expert-level proficiency with SIEM solutions, including architecting monitoring dashboards and fine-tuning alerting systems for low-noise, high-precision detections.

• Deep expertise in threat modeling and threat hunting, with the ability to proactively strengthen detection capabilities against evolving attack techniques.

• Strong proficiency in detection-as-code methodologies and custom detection engineering in cloud, endpoint, and application security environments.

• Hands-on experience developing automated security tooling using Python, Bash, or Go.

• Proven ability to conduct security audits and drive actionable security improvements based on findings.

A strong advocate for security awareness, capable of leading training and knowledge-sharing initiatives.

Nice to Have

• Experience leading purple team exercises and incident response simulations.

• Experience mentoring and developing junior security engineers.

• Knowledge of compliance frameworks (SOC 2, ISO 27001, GDPR) and their application to detection engineering.

A portfolio of security research, blog posts, or public speaking engagements on security topics.
