Lead Threat Hunter

At Allstate, great things happen when our people work together to protect families and their belongings from life’s uncertainties. And for more than 90 years, our innovative drive has kept us a step ahead of our customers’ evolving needs. From advocating for seat belts, air bags and graduated driving laws, to being an industry leader in pricing sophistication, telematics, and, more recently, device and identity protection.

Job Description

We are seeking a Lead Threat Hunter to lead hypothesis-driven, intelligence-led hunts across enterprise, cloud, and OT/IoT environments. This role proactively identifies adversary tradecraft that evades existing detections, operationalizes findings into durable detection logic, and partners with Threat Intelligence, Detection Engineering, IR, Exposure Management, and REM to reduce dwell time and shrink the enterprise exposure plane. The hunter will leverage MITRE ATT&CK, the Pyramid of Pain, and the Diamond Model to drive measurable risk reduction.

Key Responsibilities

Lead hypothesis-driven, intelligence-led hunt campaigns from formulation through reporting, mapped to MITRE ATT&CK

Design and execute custom analytics against large-scale security telemetry (SIEM, EDR/XDR, identity, cloud, network) to uncover adversary tradecraft that evades existing detections

Perform identity-centric hunting across Entra ID, Active Directory, and SaaS platforms - token theft, session hijacking, MFA bypass, OAuth abuse, and conditional access circumvention.

Conduct cloud-native hunting across AWS, Azure, M365, and SaaS control planes, including audit logs, identity events, and workload telemetry.

Convert hunt findings into durable detections, signatures, and SOAR playbooks in partnership with Detection Engineering, closing the hunt-to-detect loop

Perform Deception Operations by defining adversary-aligned use cases, authoring detection requirements for deception-generated activity, and tuning signal vs. noise thresholds

Leverage AI and LLM-assisted tooling to accelerate hunting - including query generation, log summarization, entity pivoting, anomaly clustering, and large-scale pattern discovery across disparate telemetry sources

Hunt within AI and LLM environments - including enterprise copilots, internal/external LLM deployments, AI agents, RAG pipelines, model endpoints, and AI/ML infrastructure - for threats such as prompt injection, model abuse, data exfiltration via AI channels, agent hijacking, supply-chain compromise of models, and unauthorized model access

Produce post-hunt reports with explicit evidence and measurable outcomes tied to exposure reduction

Partner with Threat Intelligence to operationalize finished intel into targeted hunt missions and feed collection requirements upstream

Support purple team exercises and validate detection efficacy against adversary emulation campaigns (Atomic Red Team, CALDERA, Stratus Red Team)

Develop and maintain custom tooling and automation to support hunting, investigation, and analyst efficiency

Mentor junior hunters; contribute to internal knowledge bases, hunt libraries, and team training

Support Incident Response, Forensics, and Insider Threat/Fraud investigations as a senior technical resource when adversary expertise is needed

Serve as a liaison for Threat Services across Cyber Operations, communicating findings clearly to technical peers and executive leadership

Identify needs, drive solutions, and operate autonomously within strategic priorities

Identify visibility and telemetry gaps discovered during hunts and partner with engineering teams to improve enterprise collection coverage
