Senior Security Engineer, Automated Detection & Response

Chicago, IL | Denver, CO | Phoenix, AZ | Remote, US
About Caribou 

At Caribou, we care about giving people financial freedom so they can focus on what’s most important to them. Today, less than two percent of Americans refinance their auto loans despite drastic increases in the cost of new and used cars. We see huge potential to help folks reduce their monthly auto expenses, as well as increase the predictability of those expenses over time. We do this by building technology to pair customers with community banks and credit unions, and ushering them through the process quickly. On average, our drivers save $159/month on their car loans while protecting their investment long term. 

Caribou is led by leaders from the technology, automotive, and finance industries. We’re proud to be backed by a great team of investors, including QED Investors, Goldman Sachs, Moderne Ventures, Accomplice, Link Ventures, Motley Fool Ventures and others.

About the Role

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.

Outcomes:

  • Maintain strong security posture by leading SOC investigations, threat hunting, and incident response
  • Improve MTTD and MTTR in Year 1 by designing and building AI-assisted triage automation and reducing manual effort
  • Cut false positive rate and improve threat visibility by injecting business context into detection logic
  • Identify adversaries who bypass automated detection through proactive threat hunting
  • Build cross-functional relationships to understand our customers, products, and processes

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.

Interview Roadmap

  • Recruiter phone interview (30 mins)
  • At-home Python coding assessment (60 mins, AI code assist IDE)
  • Hiring Manager video interview (45 mins)
  • Final interview loop (combined ~4 hrs scheduled across 1-4 business days):
    • SOC Fundamentals Interview (45 mins)
    • Security Breadth & Culture Interview (60 mins)
    • Technical Security / EDR Investigation Interview (60 mins)
    • AI & Automation Architecture Interview (60 mins)

What We Look For

You don't need to check every box. If you bring most of these and are excited to grow into the rest, we want to hear from you.

  • 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

Nice to have: GCP SecOps/Chronicle, CrowdStrike, Python, prior fintech experience

We value diverse paths into security. Whether you came through IT, engineering, or a non-traditional route, we're interested in what you've built.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
