The role

We are seeking an experienced Threat Hunting Team Lead to join the Cyber Security organization, reporting to the Head of Proactive Security under the CISO.
This role is responsible for leading the organization's proactive threat hunting program across Nebius's corporate IT environment, cloud platforms, and data center infrastructure. You will lead a team of threat hunters focused on identifying advanced threats, uncovering adversary activity before it becomes an incident, and continuously improving the organization's detection capabilities.
The ideal candidate combines strong technical expertise with an attacker mindset and a passion for proactive defense. You will work closely with SOC, Incident Response, Threat Intelligence, Detection Engineering, and Security Engineering teams to identify emerging threats, develop hunting methodologies, and strengthen Nebius's overall cyber resilience. 

Your responsibilities will include: 

• Lead and manage the Threat Hunting team, including mentoring, prioritization, and professional development.  
• Define and execute the organization's proactive threat hunting strategy across corporate IT, cloud environments, and data center infrastructure.  
• Lead hypothesis-driven threat hunting activities to identify advanced threats, persistence mechanisms, and malicious activity not detected by existing security controls.  
• Develop and continuously improve threat hunting methodologies, playbooks, and operational procedures.  
• Leverage threat intelligence, adversary TTPs, and MITRE ATT&CK to drive hunting campaigns and prioritize hunting efforts.  
• Hunt across endpoint, identity, network, cloud, and application telemetry to identify suspicious behavior and indicators of compromise.  
• Collaborate with SOC and Incident Response teams to validate findings, support investigations, and improve incident response capabilities.
