Senior Security Operations Engineer

As a Senior Security Operations Engineer at Paxos, you serve on the front lines of the security program, detecting, investigating, and containing threats across endpoints, cloud infrastructure, and network. You act as both an investigator and a builder: triaging and resolving security incidents with precision while continuously improving detections and automations that help the team move faster and operate more effectively.

What you'll do

• Triage, investigate, and respond to security alerts across endpoints, cloud infrastructure, and network telemetry
• Automate repetitive workflows and apply AI to increase speed, scale, and effectiveness of security operations
• Execute containment and remediation actions for confirmed incidents while following and continuously improving established runbooks
• Tune and maintain SIEM and EDR detections to reduce false positives, strengthen signal quality, and close coverage gaps
• Apply threat intelligence, including IOCs and TTPs, to active investigations and ongoing monitoring
• Participate in the on-call rotation and contribute clear, actionable post-incident documentation
• Mentor teammates, raise the quality of investigative work, and influence security operations processes, tooling, and standards

What you bring

• 5+ years of experience in security operations, detection and response, or a related security engineering role
• Deep experience leading investigations and response efforts across endpoints, cloud environments, and network telemetry, and the ability to independently manage complex security incidents from initial triage through containment, eradication, and recovery
• Strong analytical judgment, mature decision-making, and a calm, methodical approach to high-severity alerts and incidents, including the ability to prioritize effectively and guide others through ambiguity
• Advanced hands-on experience with SIEM and EDR platforms, including building and tuning detections, improving signal quality, reducing false positives, and shaping detection strategy based on evolving threats
• A builder's mindset with the ability to continuously identify opportunities to automate repetitive security workflows and apply AI thoughtfully to improve the speed, consistency, and scale of investigations and response
• Skill in applying threat intelligence, including IOCs, TTPs, and adversary tradecraft, to investigations, proactive threat hunting, and the continuous improvement of monitoring and detection capabilities
• Comfort participating in an on-call rotation and a track record of documenting incidents clearly and thoroughly while driving post-incident reviews and operational improvements
