Altruist is transforming the wealth management industry with an AI platform for financial advisors. The company is seeking a Security Operations Manager to lead detection, response, and 24/7 security monitoring for a self-clearing broker-dealer platform. In this role, you will lead and mentor the security operations and detection & response team, setting priorities and career development paths. You'll own the 24/7 security monitoring strategy across managed detection & response providers and run the incident response program end-to-end, from detection through containment, eradication, recovery, and post-incident review. Key responsibilities include defining and reporting SecOps metrics and SLAs (MTTD/MTTR, alert quality, coverage) to security and executive leadership; maturing detection engineering, threat-intelligence ingestion, and response automation (SOAR) capabilities; driving regular tabletop and purple-team exercises; and partnering with Cloud, IT, and Engineering teams to close security gaps. You'll also own the day-to-day operation and roadmap of the security operations tooling stack. Required qualifications: 6+ years in security operations with 2+ years leading or managing a SOC or detection & response team. Hands-on incident response and investigations in cloud-first environments. Depth with SIEM tools (Datadog/Splunk), EDR/MDR solutions (CrowdStrike/SentinelOne), and AWS cloud telemetry. Experience managing MDR/MSSP and/or IR retainer relationships. Bachelor's degree in Computer Science, Computer Engineering, Information Security, or equivalent experience. Technical aptitude across modern cloud and detection stacks (AWS, Kubernetes, SIEM query languages, detection-as-code, Terraform). Strong leadership through influence, communication skills, ownership mindset, and creative problem-solving abilities. Bonus: Experience in regulated environments (SEC/FINRA, fintech). The role follows a hybrid schedule with three days per week onsite in San Francisco FiDi or Culver City office.
