Sr. Incident Responder

This is a Senior/Lead Incident Response analyst position on Fiserv’s Cyber Security Incident Response Team, built for a true incident response expert. You will be the escalation point when a routine security event becomes a real incident, and you will lead the response from first escalation through containment, root cause, and after-action reporting. Our Tier 2 team is growing into the role, so you will also set the standard for how incidents are run and raise the skill level of the analysts around you.

You will step in as incident commander, direct cross-functional teams during high-pressure incidents, brief everyone from application managers to executives, and mentor analysts using real incidents as teaching moments

What you’ll do

• Act as incident commander when an event is escalated to a true incident, coordinating application, infrastructure, and cybersecurity teams to contain issues such as removing an unauthorized user from a server or isolating malware.
• Lead investigations end to end: scope the incident, develop and test hypotheses on how it occurred, direct containment and remediation, and drive root cause analysis.
• Provide clear direction on incident bridges, assign responsibilities, and keep the response organized and on track under pressure, including when information is incomplete.
• Serve as the technical escalation point for Tier 2 and Tier 1 analysts, helping them decide what is and is not a true incident and what the right response is.
• Coach and mentor analysts using completed incidents as case studies, covering both technical methods (e.g., crafting Splunk queries) and soft skills (e.g., calming an application team).
• Communicate diplomatically with application managers, executives, and cross-functional stakeholders, tailoring the level of technical detail to each audience.
• Write after-action reports and incident summaries for audiences ranging from executives and sales to technical and management teams.
• Use CrowdStrike and comparable EDR platforms to contain network assets, remotely access affected systems, and collect system information during investigations.
• Help build and improve incident response playbooks, escalation procedures, and lessons-learned practices so the team gets stronger after every incident.
• Participate in the on-call rotation approximately every four to six weeks, keeping your phone nearby to be engaged first when an incident occurs.

• 6+ years of hands-on incident response experience, including leading real, confirmed security incidents (such as ransomware, business email compromise, malware, or network intrusion). This is not limited to alert triage or SOC monitoring.
• Demonstrated experience serving as an incident lead or commander, including containment, remediation, and stakeholder communication during active incidents.
• Ability to describe in detail the incidents you have personally led, the decisions you made, and the tools you used.
• Hands-on experience with EDR tools. CrowdStrike experience is preferred; comparable tool experience is acceptable.
• Strong communication skills, with the ability to work diplomatically with other teams, executives, and application managers while taking charge and assigning responsibilities.
• Ability to write clear after-action reports and summaries tailored to technical and non-technical audiences.
• Demonstrated ability to mentor or coach other analysts on both technical methods and soft skills.
• Ability to perform under pressure, take charge of a situation, and make sound decisions with incomplete information.
• A collaborative mindset and genuine curiosity about cybersecurity fundamentals, adversaries, threats, and their potential impact on the environment.
• Willingness to participate in on-call coverage approximately every four to six weeks.

Experience that would be great to have

• Industry certifications such as GCIH, GCFA, CISSP, Security+, or other SANS credentials, recent or in progress.
• Digital forensics, malware analysis, or threat hunting experience.
• Experience crafting Splunk queries or similar SIEM searches to support investigations and mentoring.
• Experience in a consulting, retainer, or DFIR firm environment, or in financial services or payments.
• Prior experience partnering with a 24/7, globally distributed SOC or incident response team.
• Familiarity with additional EDR/XDR, SIEM, or SOAR platforms beyond CrowdStrike.
• Active engagement with the cybersecurity community, signaling ongoing learning about current threats.

• Location: This role can be based in Berkeley Heights, NJ, Alpharetta, GA. or Columbus, OH. These locations will be considered based on candidate fit and experience.
• Schedule: Regular Monday-Friday, 9:00 a.m.-5:00 p.m., with an on-call rotation approximately every four to six weeks.
• Travel: Minimal travel is expected for this role.
