Employment Type: Full Time
Location: ESP Madrid
Description
We are seeking a highly capable and hands-on Threat Hunter to join a passionate and motivated, industry-leading team focused on identifying sophisticated adversaries through hypothesis-driven analysis and automation. You will be responsible for proactively hunting and analysing advanced threats across the customers environment using our proprietary hunting framework, ensuring our threat models and threat hunts are tightly aligned to the customer.
As a Threat Hunter, you will actively search for cyber threats that evade traditional security solutions. Your role will involve conducting in-depth intelligence-led, hypothesis-driven analysis of TTPs and behaviours, and working cross-functionally with the Security Operations Centre Analysts, Global Detection Engineers, Privacy Team and Engineering Team to mitigate risks.
Key Responsibilities
Use NCC Group’s HITS Framework, threat intelligence, MITRE ATT&CK, and risk models to form hypotheses and validate them through structured hunts.
Leverage GitLab, Sigma, Jupyter Notebooks and other tools to automate hunts, visualise results, and create reusable artifacts for future investigations and detections.
Collaborate with detection engineering to convert threat hunt findings into high fidelity detection content.
Utilising both NCC Groups internal threat intelligence feeds and open-source threat intelligence, use these to operationalise detections for emerging threats.
Support the mapping of threat models to monitoring use cases in partnership with teams across the business.
Document and maintain a robust repository for hunting methodologies, tooling, and findings to enable continuous improvement and team scaling.
Provide regular reports and presentations to stakeholders, with clear articulation of threats, methods, and risk impact.
