  • Define and report on SecOps metrics and SLAs (MTTD/MTTR, alert quality, coverage) to security and executive leadership.
  • Hands-on incident response and investigations in a cloud-first environment
  • Experience - 6+ years in security operations, including 2+ years leading or managing a SOC or detection & response team:
  • Resilience - We’re inspired by your unwavering determination to achieve success, no matter the adversity you face along the way
  • Experience managing an MDR/MSSP and/or IR retainer relationship
  • Ownership - The pride you put into every aspect of your work is unparalleled and undeniable
  • 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.)
  • 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
  • Strong ability to lead through influence and operate with urgency
  • Creative problem solving - Identifying the problem is simply not enough. You’re instinctually creative with your approach in finding solutions to roadblocks
  • Depth with SIEM (Datadog/Splunk), EDR/MDR (CrowdStrike/SentinelOne), and cloud telemetry (AWS)
  • If you’re excited about this role, but your past experience doesn’t align perfectly with every qualification in the job description, we encourage you to apply anyways
