Incident Response Lead

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 Benefits & Perks: Competitive compensation Career growth and learning opportunities Flexibility and ownership Collaborative and innovative culture Opportunity to work on impactful AI projects International environment and talented teams What Nebius is like to work at: Fast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI Equal Opportunity Statement: Nebius is an equal opportunity employer.
