Job Description
Amex GBT is a place where colleagues find inspiration in travel as a force for good and – through their work – can make an impact on our industry. We’re here to help our colleagues achieve success and offer an inclusive and collaborative culture where your voice is valued.
We are seeking a Senior Detection Engineer to join our Cyber Defense organization, reporting to the Manager of Threat Detection and Response. This is a fully remote, US-based role with a preference for candidates located in the western United States (West Coast or Rocky Mountain region). You will be a core technical contributor on a diverse, globally distributed, and high-performing team of 20 cybersecurity professionals, working alongside a SecOps AI engineering team and mentoring a junior detection engineer.
This role owns the full detection engineering lifecycle — from threat intelligence and hunt operations through detection-as-code development, automation, and critical incident response. If you are energized by building detection capabilities from the ground up, thrive in a fast-paced SOC environment, and want to do it with a team that takes craft seriously, we want to hear from you.
What You'll Do
Detection Engineering
- Design, build, and maintain detection logic using CrowdStrike, leveraging its EDR telemetry to identify advanced threats
- Develop and operationalize detection-as-code, including custom queries and correlation rules
- Conduct cyber threat intelligence (CTI) analysis and proactive threat hunting to surface novel attack patterns
- Continuously tune and improve detection fidelity, reducing false positives and improving signal quality
Automation and Orchestration
- Build and maintain automated response workflows and playbooks in Tines
- Collaborate with the SecOps AI engineering team to integrate AI-driven capabilities into detection and response pipelines
- Manage detection content and automation code in GitHub, applying software engineering best practices (version control, code review, CI/CD)
- Write Python scripts to extend automation, parse data, and support detection development
Incident Response and DFIR
- Serve as a senior technical resource for critical incident response, including after-hours and weekend escalations for high and critical severity events
- Apply digital forensics and incident response (DFIR) expertise to investigate, contain, and remediate security incidents
- Develop and refine incident response playbooks and post-incident documentation
- Lead or support SOC incident management in the absence of the manager
Leadership and Mentorship
- Mentor and develop a junior detection engineer through regular guidance, code review, and knowledge sharing
- Deliver monthly cybersecurity training sessions for the broader team
- Generate monthly platform performance reports and contribute to strategic planning discussions
- Evaluate emerging security technologies and contribute to proof-of-concept assessments
