Role Overview
The Senior Engineer Threat Hunting will be a senior individual contributor within Cboe’s Security Operations organization, responsible for defining, advancing, and executing the enterprise approach to detection engineering, threat hunting, and adversary emulation. This role focuses on building and maturing detection capabilities across platforms such as SIEM, EDR, identity, cloud, and SaaS environments, ensuring detections are resilient, scalable, and aligned to real‑world adversary behavior. The Senior Engineer Threat Hunting will lead complex, hypothesis‑driven threat hunts, partner closely with stakeholders to design and execute adversary emulation scenarios, and translate findings into durable detections, improved telemetry, and architectural enhancements. This individual will also serve as a technical lead during the most complex or high‑severity security incidents, shaping investigative approach and long‑term defensive improvements.
PLEASE NOTE: To support strong partnership and team connection, this role follows a four day in office work model.
In this role you’ll be responsible for
Owning the enterprise detection engineering capability end‑to‑end, including standards, patterns, quality bars, and long‑term technical direction
Designing, implementing, and reviewing high‑fidelity detections across endpoint, identity, cloud, network, and SaaS environments
Leading complex, hypothesis‑driven threat hunts that address ambiguous, cross‑organizational risk and novel attacker behavior
Translating threat hunting outcomes into robust detections, improved telemetry, or architectural changes rather than one‑off findings
Partnering with internal stakeholders to design and execute adversary emulation scenarios that validate real‑world detection and response effectiveness
Identifying systemic detection and response gaps and driving remediation across engineering, operations, and architecture teams
Acting as the technical lead during highest‑severity incidents, guiding investigative approach and defensive improvements
Influencing security strategy, roadmaps, and investment decisions by translating technical findings into business and risk context
Provide expert recommendations and best practices to security managers, technical managers, and stakeholders including legal and regulatory teams.
Mentoring senior engineers and analysts and setting the technical bar for excellence across detection, hunting, and adversary emulation
Stay current with industry trends, security standards, and best practices to ensure our systems remain secure against evolving threats.
The ideal candidate has
5-8+ years of experience in cybersecurity operations, detection engineering, threat hunting, or offensive security
Deep expertise in attacker tradecraft, adversary behaviors, and defensive detection techniques across multiple domains
Strong hands‑on experience with SIEM, EDR, cloud security platforms, and large‑scale log analytics (Google SecOps, Defender XDR, Crowdstrike)
A proven ability to solve ambiguous, systemic, cross‑organizational security problems with minimal direction
Experience balancing hands‑on execution with strategic influence, knowing when to build directly and when to enable others
The ability to operate with near‑complete autonomy, setting technical direction rather than receiving it
Strong communication skills, including the ability to explain complex technical risk to senior security and technology leaders
Bachelor’s degree or equivalent practical experience
Proficiency in scripting and automation for security operations.
You’ll really stand out with
Bachelor's Degree in Cybersecurity or Computer Science
