Welcome to Kyndryl, where Cybersecurity isn't just a job – it’s a passion; a commitment to designing, running, and managing the most modern and reliable technology infrastructure that the world depends on every day. As a Senior Cyber Defense Analyst at Kyndryl, you will play a critical role in protecting customers and Kyndryl environments through cybersecurity operations, incident response, digital forensics, threat hunting, detection engineering, and security investigations. Unlike traditional Security Operations Center (SOC) environments, this role owns investigations from start to finish, giving you the opportunity to manage the full lifecycle of an incident from initial alert triage through investigation, containment, remediation, and recovery. In this role, you won't just monitor alerts; you'll actively investigate and respond to cyber threats across complex enterprise environments. You will leverage your experience with Security Information and Event Management (SIEM) platforms, endpoint detection capabilities, and security telemetry to identify, analyze, and respond to threats. Whether conducting threat hunting activities, building detections, or performing digital forensic investigations, your expertise will be instrumental in strengthening our cyber defense capabilities. Your responsibilities go beyond operational monitoring. You will develop and tune detections, write and optimize security queries, perform proactive threat hunting, and conduct detailed investigations into suspicious activity and security incidents. You will collaborate with security professionals across the organization, applying investigative techniques and threat intelligence to identify indicators of compromise and emerging threats before they become material risks. In Cybersecurity Defense at Kyndryl, you’re not just protecting the present – you’re shaping the future of digital security.

You’re good at what you do and possess the required experience to prove it. However, equally as important – you have a growth mindset; keen to drive your own personal and professional development. You are customer-focused – someone who prioritizes customer success in their work. And finally, you’re open and borderless – naturally inclusive in how you work with others. Required Skills and Experience Proven experience in cybersecurity operations, incident response, threat hunting, or cyber defense roles. Hands-on experience managing security incidents through the full investigation lifecycle, from alert triage to remediation and closure. Experience with SIEM platforms such as Splunk, Microsoft Sentinel, QRadar, Elastic, LogRhythm, or similar technologies. Strong investigative and analytical skills with the ability to identify, analyze, and respond to complex cyber threats. Experience in detection
