Cybersecurity Engineer

Summary of Responsibilities:

Join a Great Place to Work! We’re looking for a Cyber Security Engineer focused on threat detection & response to join our growing team. In this role, you’ll be instrumental in enhancing ATC’s cyber defense capabilities by developing and implementing threat detection strategies, analyzing security data, and responding to potential threats—helping to protect a vital part of the nation’s critical infrastructure.

Essential Responsibilities:

You’ll be instrumental in elevating our security posture by:

• Designing and tuning detection logic to identify emerging threats and reduce false positives
• Proactively hunting for threats across ATC’s environment using behavioral analytics and threat intelligence
• Accelerating incident response through automation, playbook development, and cross-team collaboration
• Enhancing visibility into security events by optimizing log sources and data ingestion in Splunk
• Driving continuous improvement of our detection and response capabilities through lessons learned and post-incident reviews
• Collaborating with IT and OT teams to ensure security is embedded in infrastructure and operational technologies
• Contributing to red/blue team exercises and tabletop simulations to test and strengthen our defenses
• Optimizing notable event and alert triage, dashboard oversight, SEIM and Linux-system management, and compliance tasks

This position could be located out of our Pewaukee, Cottage Grove or De Pere, Wisconsin offices or our Kingsford, Michigan office. If you’re proactive, adaptable, and driven to contribute to a mission that matters—ensuring power delivery and protecting vital infrastructure—this is your opportunity. We offer flexible work schedules, though this role is not 100% remote and requires relocation to an area close to one of our Wisconsin or Upper Peninsula office locations. Bring your positive energy and help us lead, motivate, and influence internal and external stakeholders to meet compliance specifications and expectations!
