Summary of the Role As Director of Cybersecurity at Calamos, you'll be the CISO's right hand in executing our comprehensive security strategy, serving as the operational backbone of our Information Security Program. This is a high-impact, individual contributor, leadership role where you'll own the day-to-day security operations protecting billions in assets and sensitive financial data from sophisticated cyber threats. You'll manage our security operations center—orchestrating incident response, managing enterprise security tools, and ensuring our defenses stay ahead of emerging threats. Think of yourself as the bridge between strategic vision and tactical excellence. While the CISO sets the course, you'll be the one making it happen—leading teams through critical incidents, implementing cutting-edge security technologies, and ensuring seamless 24/7 protection across our infrastructure.

You'll be the go-to expert who translates complex threats into actionable defenses, manages relationships with key security vendors, and ensures our vulnerability management program stays best-in-class. When incidents strike—day or night—you'll lead from the front with technical expertise and cool-headed decision-making. We're seeking a seasoned, individual contributor, security leader who combines deep technical knowledge with strong operational excellence. You're someone who thrives in dynamic environments, can manage multiple critical initiatives simultaneously, and has proven success in building and running enterprise security operations. If you're ready to be the operational force behind a world-class security program and want to work alongside forward-thinking security leadership, this is your opportunity to excel.
