The role

Nebius is seeking a deeply technical Incident Response Lead to build and lead the company’s global incident response capability - its people, tooling, and methodology - while remaining the hands-on technical authority on the hardest investigations. Reporting into the CISO Office, the Lead grows and directs a follow-the-sun team of responders across EMEA, Asia, and APAC, owning response execution and quality across Nebius’ cloud, infrastructure, and platform environments.

This is a hands-on role that balances deep technical work alongwith building and running the function: the Lead drives high-severity incidents end-to-end, serves as the escalation ceiling, and sets the standards and structure the team operates by.

 You’re welcome to work in our offices in Tel Aviv, Israel.

Your responsibilities will include: 

• Build and lead Nebius’ global IR capability - select and mature DFIR tooling, and establish the playbooks and follow-the-sun operating model across EMEA, Asia, and APAC while hiring and developing a team of responders.
• Lead the technical response to major incidents hands-on - from escalation through containment, eradication, and recovery - and act as the final technical authority on the most complex cases.
• Personally conduct end-to-end forensic investigations across cloud, platform, and endpoint environments - log analysis at scale, host and network forensics, memory analysis, malware triage, and timeline reconstruction.
• Define and enforce consistent investigation standards across the team: severity and escalation criteria, cross-region handoff quality, and evidence handling that meets legal, regulatory, and forensic requirements.
• Partner with the SOC, SOC Automation, Threat Intelligence, Threat Hunting, and Platform Security teams to improve detection fidelity and reduce MTTD and MTTR.
• Serve as the technical voice of incident response to executive leadership, Legal, and Privacy - delivering clear, risk-based briefings, regulatory-ready documentation, and root cause analyses (RCA).
• Raise the team’s technical bar through case reviews and hands-on mentoring, and drive lessons-learned into measurable improvements in controls and readiness.

We expect you to have: 

Experience

• 8+ years of hands-on incident response and digital forensics, including technical leadership of large-scale, high-impact incidents (ransomware, nation-state / advanced threat actors, cloud intrusions, identity compromise).
• Experience building or leading IR teams and capabilities in cloud or infrastructure-heavy environments, which are highly regulated (SOC 2, ISO 27001, GDPR/NIS2).

Technical Expertise

• Deep knowledge of Windows and Linux internals, with proven disk and memory forensics capability.
• Strong cloud-native platform security: containers and Kubernetes, CI/CD, secrets management, cloud control planes, and IAM attack paths.
• Fluency in attacker TTPs (MITRE ATT&CK, including the Cloud and Containers matrices), and hands-on experience with EDR, SIEM, and forensic tooling (e.g., Velociraptor, Volatility, X-Ways/EnCase).
• Strong scripting and data-analysis skills (Python, PowerShell, SQL/KQL) for investigation at scale, with the ability to validate findings independently and challenge assumptions.

Leadership & Communication

• Proven ability to lead under pressure and make high-quality decisions with incomplete data; technical leadership through credibility across regions, without relying on direct authority.
• Clear, concise communicator capable of briefing executives, Legal, Privacy, and non-technical stakeholders.
• Working knowledge of spoken and written English
