Cyber Threat Hunter

About the Role 

We are looking for a Threat Hunter to join our Cyber Threat Intelligence function and run proactive, hypothesis-driven hunts across our environment. This is a dedicated hunting role at the front of a detection pipeline: you will turn intelligence and adversary tradecraft into concrete hunts and turn what you find into detection packages that our tooling team operationalizes and our SOC consumes as tuned, documented alerts.

You will sit at the intersection of threat intelligence, detection engineering, and offensive validation. Working from CTI and from our red teamer's findings, you will hunt for activity that never trips an existing alert, novel techniques, living-off-the-land tradecraft, misconfiguration abuse, and long-dwell intrusions, and close those gaps by feeding durable detections and configuration fixes back into the organization. It is a role for a curious, methodical hunter who is energized by long-horizon investigation rather than the pace of the alert queue.

Location: We are flexible on remote working from home, if you are located in the USA and reside in one of the following states: CA, CO, CT, FL, GA, *IL, KS, MA, MD, ME, NJ, NC, NY, OH, OR, TN, TX, VA, and WA. We have physical offices in Austin, TX and Tampa, FL, if you prefer a hybrid option.

*Onsite interviews may be required for this role.

What You'll Be Doing 

• Plan and run hypothesis-driven hunts (intel-led, TTP-led, and behavior-led) across endpoint, identity, cloud, and network telemetry
• Consume CTI and red-team/purple-team findings to prioritize hunts against the adversary behaviors most relevant to us
• Map hunts and findings to MITRE ATT&CK to track coverage and expose blind spots
• Translate hunt findings into detection packages and recommendations, including detection logic, required context and enrichment, and draft SOP guidance, for the tooling team to operationalize
• Partner with the red teamer on purple validation of configuration faults and security-posture gaps
• Surface configuration faults and posture gaps discovered during hunts, and drive recommendations to close them
• Document hypotheses, methods, and outcomes so hunting knowledge lives in reusable artifacts rather than in one person's head
• Contribute threat context and hunt-derived intelligence during declared Sev 1 incidents, in an advisory (non-primary) capacity
• Other duties as needed

About You 

• 5+ years in a security operations, detection engineering, CTI, or incident response role, with meaningful hands-on threat-hunting responsibility
• Demonstrated experience running hypothesis-driven hunts, forming a hypothesis, testing it against telemetry, and driving it to a conclusion, not solely alert triage
• Strong working knowledge of adversary tactics, techniques, and procedures, and practical fluency with the MITRE ATT&CK framework
• Proficiency querying and pivoting across security telemetry at scale in a SIEM and/or EDR/XDR (e.g., KQL, SPL, or equivalent query languages)
• Solid understanding of endpoint, identity, cloud, and network telemetry, and a sense of what normal and abnormal look like in each
• Ability to turn a hunt finding into a detection recommendation, including logic, supporting context, and fidelity/signal-to-noise considerations
• Understanding of the detection lifecycle and why signal-to-noise quality matters to a SOC
• Clear written communication for documentation, detection packages, and SOP recommendations
• Able to plan and sustain long-horizon hunt campaigns with limited day-to-day direction

Preferred Qualifications 

• Experience consuming red-team or purple-team output to drive and prioritize hunts
• Scripting for automation and enrichment (Python preferred)
• Familiarity with detection-as-code workflows and version-controlled detection content
• Depth in cloud-native and SaaS telemetry (CloudTrail, Entra ID/Azure AD, SaaS audit logs)
• Experience with a threat intelligence platform (TIP) and structured intel workflows
• Exposure to an IR-capable or standing-response team environment
• Relevant certifications, one or more (preferred, not required):
• GCTI, GCFA, GCDA, GCIA, or similar GIAC certifications
• OSCP or comparable (for offensive-tradecraft awareness)
• Cloud security certifications (AWS, Azure, or GCP), or equivalent

Key Skills 

• Adversary mindset, thinks in behaviors and TTPs, not indicators alone
• Patience and persistence for long-horizon threads that may not pay off immediately
• Strong analytical and data-pivoting skills across large, varied datasets
• Translates findings into durable, reusable detections and clear documentation
• Communicates effectively across CTI, tooling, and SOC audiences
• Curiosity and a genuine drive to find what existing alerting misses

What You'll Love 

• A collaborative, kind, and curious community
• Full-time work that is hybrid remote, honoring your flexibility needs
• A comprehensive benefits package, including medical, dental, and vision insurance
• A 401(k) plan to help you prepare for your financial future
• Unlimited PTO that prioritizes your work-life balance
• Opportunity for growth and advancement
