Cyber Threat Hunter

About the Position

Cyber Threat Hunter

At ING Hubs Spain, we are looking for a Senior Cyber Threat Hunter. Are you driven by curiosity and motivated to stay ahead of cyber adversaries? As a Senior Cyber Threat Hunter, you will proactively uncover advanced and hidden threats before they become incidents. You will think like an attacker, challenge assumptions, and help strengthen ING’s resilience against evolving cyber risks.

Responsibilities

• Proactively conduct intelligence-led threat hunting and emulation based on emerging threats, adversary activity, and major external cyber incidents.
• Develop and test hypothesis-driven investigations to identify unknown or evasive malicious activity.
• Analyse adversary behaviour across the full attack chain, identifying detection and control gaps.
• Translate hunt outcomes into actionable improvements for detection, prevention, and defensive architecture.
• Map findings to MITRE ATT&CK to clearly articulate threats, gaps, and priorities.
• Communicate investigation outcomes in clear, executive-ready reports that support risk-based decision-making.
• Leverage automation, AI-assisted analytics, and Breach & Attack Simulation (BAS) to continuously validate threat hypotheses, test adversary techniques, and prioritise high-risk attack paths.

Requirements

• Several years of hands-on experience in hypothesis-based threat hunting activities, purple teaming, or security research.
• Experience with threat hunting methodologies, such as TaHiTi, PEAK, or others.
• Proven experience in large enterprise environments, with technologies such as CI/CD, multi-cloud, and containers.
• Ability to translate threat intelligence into concrete, high-impact investigations.
• Skill in identifying and validating meaningful security gaps rather than chasing alerts or noise.
• Capacity to think and reason like an adversary while emulating attack scenarios.
• Ability to deliver investigation outcomes that improve detection, controls, or resilience.
• Clear communication of complex threats to both technical and non-technical stakeholders.
• Ability to work effectively in an environment with ambiguity, autonomy, and high trust.

Nice to Have

• Experience or relevant certifications in cyber threat hunting, detection engineering, or adversary simulation (e.g., GIAC, MITRE ATT&CK, cloud security, or BAS-related certifications) are considered an advantage.

We Offer

• Flexible work model with a hybrid approach.
• Restaurant card.
• Comprehensive health and life insurance.
• Flexible remuneration model.
• Transport allowance.
• Pension plan.
