What you’ll do

• Lead, mentor, and grow the security operations / detection & response team, setting priorities and career paths.

• Run the incident response program end to end — from detection through containment, eradication, recovery, and post-incident review.
• Define and report on SecOps metrics and SLAs (MTTD/MTTR, alert quality, coverage) to security and executive leadership.
• Mature our detection engineering, threat-intelligence ingestion, and response automation (SOAR) capabilities.
• Drive regular tabletop and purple-team exercises and partner with Cloud, IT, and Engineering to close gaps surfaced by monitoring.
• Own the day-to-day operation and roadmap of the security operations tooling stack.

What you’ll bring

• Experience - 6+ years in security operations, including 2+ years leading or managing a SOC or detection & response team:
• Hands-on incident response and investigations in a cloud-first environment
• Depth with SIEM (Datadog/Splunk), EDR/MDR (CrowdStrike/SentinelOne), and cloud telemetry (AWS)
• Experience managing an MDR/MSSP and/or IR retainer relationship
• Strong ability to lead through influence and operate with urgency
• Education - A B.A. / B.S. degree in relevant fields such as Computer Science or Computer Engineering or Information Security or relevant experience
• Technical aptitude - You’re technologically savvy and comfortable across modern cloud and detection stacks (i.e., AWS, Kubernetes, SIEM query languages, detection-as-code, Terraform, etc.)
• Ownership - The pride you put into every aspect of your work is unparalleled and undeniable
• Superb communication - Intentional dialogue is a superpower. You listen as well as you share your perspective with others.
• Resilience - We’re inspired by your unwavering determination to achieve success, no matter the adversity you face along the way.
• Assurance - Your confidence is brilliant, yet ego-less. You possess a strong knowledge base, the ability to discover the unknown, and are open to differing perspectives.
• Creative problem solving - Identifying the problem is simply not enough. You’re instinctually creative with your approach in finding solutions to roadblocks.

Bonus points if you bring

• Experience working in regulated environments (SEC/FINRA, fintech, or financial services)
• Experience building or standing up a 24x7 SOC or transitioning to managed detection & response
• Relevant certifications (e.g., CISSP, GCIH, GCIA, GCFA)
