Threat and Vulnerability Engineer| Security Monitoring| Experienced Hire

Overview

At Susquehanna, our Security Monitoring team sits on the front lines — engineering the systems, detections, and workflows that protect our environment, while also responding to threats in real time. We’re a flat, cross-functional group of security engineers who design and build monitoring capabilities, integrate data sources, write and tune detection rules, investigate alerts, and lead incident response. If you want to apply your engineering skills to high-impact security challenges, this is the place to do it.

In this role, you will :

• Engineer, tune, and maintain the detection and monitoring systems that power our security operations.
• Develop and deploy detection rules and automation to identify threats across our environment.
• Investigate and respond to alerts and incidents, performing both rapid triage and deep forensic analysis.
• Integrate new log sources and security tools into our detection pipeline.
• Collaborate with other security teams to operationalize threat intelligence and improve our security posture.

Five Reasons to Join Susquehanna's Information Security Team :

Variety without silos — work across engineering, operations, and intelligence without being boxed into a narrow role.

End-to-end ownership — take ideas from concept through implementation, deployment, and ongoing improvement.

Collaborative expertise — join a team that values curiosity, constant learning, and sharing knowledge freely.

Proactive problem-solving — build solutions to prevent incidents, not just react to them.

Unlimited growth potential — take on new responsibilities based on skill and initiative, not tenure.
