Senior Security Engineer, Automated Detection & Response

Caribou Financial • Chicago, AZ

3d • $154 - $193 • Remote

About The Position

Caribou Technology / Security Team You'll build internal SecOps that actually understands our business. You will design and lead an AI-assisted detection pipeline, automating repetitive investigation work so you can focus on context: what's normal here, what systems matter most, and what threats actually target fintech companies like us. We're looking for someone who sees past the AI hype and uses these tools to achieve real outcomes. We practice Honest Security: transparency and partnership with employees, not surveillance. You'll join a small, senior security team and collaborate across engineering and the business to understand our environment and contextualize defense. This role may work remotely from a state where Caribou operates, with preference for the Denver, CO market. Alternatively, this role can be based out of our Caribou office in Denver, CO.

Requirements

• SOC experience: Alert triage, investigations, and incident response in a regulated environment (fintech, healthcare, etc.)
• SIEM proficiency: Strong experience with at least one major platform; you write detection rules, not just consume dashboards
• EDR investigation experience: You've used an EDR platform for real investigations, not just reviewed dashboards
• Builder track record: You've automated security workflows and reduced manual toil, including building with AI tools to achieve real outcomes
• Cloud & automation: Experience defending cloud environments (GCP, AWS, Azure) and building automation in at least one language
• Honest Security alignment: You believe security teams should partner with employees, not surveil them
