Are you passionate about building and pioneering in the technology space? Do you enjoy solving complex security problems in a fast-paced, collaborative, and iterative environment? At Capital One, you'll be part of a group of makers, breakers, doers, and disruptors who solve real problems and protect millions of customers every day.
Capital One's Cyber Organization is a fast-paced, dynamic environment committed to enabling and securing the business. Our Cyber Operations & Intelligence division is searching for an experienced Individual Contributor (IC), Manager-level Detection Engineer with deep endpoint security expertise to join our Cyber Threat Detection (CTD) team. In this role, you will own end-to-end detection coverage for our Endpoint domain — from telemetry requirements and threat landscape awareness through to coverage gap identification and high-fidelity alert deployment.
The CTD team engineers, deploys, and validates automated threat detections that protect Capital One's customers, assets, and associates. Our detections power the investigations and incident response work of the Cyber Security Operations Center (CSOC), running continuously across our enterprise SIEM, which processes over 20 million events per second across hundreds of custom detection rules and thousands of out-of-the-box. Underpinning this platform is a Detection-as-Code discipline: every detection is a YAML-based rule, version-controlled in GitHub, CI/CD deployed, peer-reviewed, and unit-tested.
In this role, you will be a senior technical contributor responsible for solving hard problems using cutting-edge technology across endpoint security engineering, alert development, EDR/endpoint log analysis, and monitoring at scale.
AI-Driven Detection & Engineering: Leverage LLMs and machine learning to automate detection logic, summarize complex attack chains, reduce false positives, and accelerate the full detection development lifecycle using tools such as Capital One's Detection Engineering Assistant.
Detection-as-Code (DaC) Leadership: Lead the design, development, and maintenance of detection rules using DaC methodologies, utilizing GenAI-assisted development workflows and CI/CD pipelines against the Cyber Detection Library (CDL).
Behavioral Detection Engineering: Design and build high-fidelity behavioral detections that identify adversary patterns, TTPs, and anomalous endpoint activity — leveraging user and entity behavior signals, process telemetry, and correlation logic to distinguish malicious from benign activity at scale.
Strategic Architecture: Utilize the MITRE ATT&CK framework to visualize, prioritize, and close endpoint coverage gaps; drive detection architecture decisions that balance fidelity, volume, and operational risk across the endpoint threat surface.
Offensive Alignment & Threat Research: Apply a deep understanding of Red Team methodologies and adversary TTPs to conduct hypothesis-driven threat research across enterprise endpoint environments — translating attacker techniques into high-fidelity detections and proactively identifying coverage gaps before they are exploited.
Endpoint Domain Ownership: Own end-to-end detection coverage for the Endpoint threat surface — managing the full lifecycle from telemetry onboarding through alert deployment, tuning, and continuous coverage gap analysis in collaboration with the Coverage Review Team.
Stakeholder & Risk Management: Partner with business leaders, CSOC, Cyber Threat Intelligence, and Cyber Threat Hunt to ensure robust monitoring across endpoint environments while ensuring all documentation meets strict fintech compliance and audit standards.
Technical Leadership & Mentorship: Serve as a technical bar-raiser across the team — mentoring engineers on traditional security concepts, emerging AI-driven workflows, and detection engineering best practices.
