DFIR Expert

The role

Nebius is seeking a deeply technical DFIR Expert for its Digital Forensics and Incident Response (DFIR) team, working alongside the Security Operations Center (SOC). This role is a senior hands-on responder position, executing containment, eradication, and recovery on declared incidents and conducting the forensic investigations behind them, upholding the standards the DFIR team operates by.

This role reports to the DFIR Lead, under the Detection and Response function within the CISO Office.

Your responsibilities will include

• Execute the technical response to major incidents from escalation through to recovery, in partnership with and under the direction of the DFIR Lead.
• Conduct end-to-end forensic investigations across cloud, platform, and endpoint environments.
• Handle evidence to a standard that meets legal, regulatory, and forensic requirements, including chain- of-custody discipline.
• Receive incident handoffs from the SOC and lead the response while the SOC continues to support the investigation.
• Produce post-incident deliverables: technical reports, root cause analyses (RCA), and regulatory-ready documentation.
• Contribute to DFIR runbooks, tooling selection and maturation, and readiness exercises (tabletops and simulations).
• Drive lessons-learned into measurable improvements in controls, detection fidelity, and response readiness together with the SOC, Security Engineering, and Threat Intelligence teams.
• Raise the wider team's forensic capability through case walkthroughs and mentoring of SOC analysts, and participate in the DFIR on-call rotation, acting as the response point of contact outside business hours.

Experience

• Around 5 years of hands-on digital forensics and incident response (DFIR) experience, including significant technical roles in large-scale, high-impact incidents (ransomware, advanced threat actors, cloud intrusions, identity compromise).
• Experience responding to incidents in cloud or infrastructure-heavy environments.
