The Role

We're hiring a Detection Engineering & Response Lead to build and run our D&R capability from the ground up. You'll own the detection engineering, threat intelligence, and incident response functions across Nebius Cloud - and lead a small, growing team of analysts and engineers.

This is a lead engineering role responsible for detection development, handling the most complex security incidents, forensics, and shaping the D&R strategy.

What you’ll do

• Lead detection development: maintain low false-positive and false-negative rates. Work closely with alerts consumers (20+ teams) to keep noise low and signal high, ensuring they can act quickly without missing genuine threats.

• Architect and operate detection coverage across our cloud and bare-metal environments

• Build and extend our internal D&R tools and pipelines - onboard new logs, build and automate response runbooks.

• Integrate threat intelligence into detection logic and IR playbooks, tracking adversary TTPs relevant to Cloud infrastructure

• Lead incident response end-to-end: scoping, containment, root cause analysis, post-incident reviews and controlling critical action items are closed to prevent future possible incidents.

• Partner with Compliance and Engineering teams to detect real threats while meeting the needs of both engineers and regulators.

• Define and report on D&R metrics: MTTD, MTTR, detection coverage, false positive rates, etc.

• Build and maintain Security Incident Response program: people, processes, tools.

• Build tools, runbooks, and on-call processes that scale as the company grows.

What we look for

• 6+ years in security operations, detection engineering, or incident response — with at least 1–2 years leading or mentoring a team.

• Deep hands-on experience with cloud-native environments (Kubernetes, Linux workloads, container-based infrastructure).

• Strong detection engineering skills: writing and tuning rules/detections in SIEM platforms (e.g., Chronicle, Splunk, Elastic) and SQL.

• Experience building or operating SOAR workflows and automating response at scale (ideally with Golang and Temporal).

• Working knowledge of threat intelligence frameworks (MITRE ATT&CK, Pyramid of Pain, Kill Chain) and how to operationalize them in detections.

• Solid IR fundamentals: memory forensics, log analysis, network traffic analysis, and post-incident reporting.

• Stakeholder management: able to coordinate across engineers, compliance, legal, executives during active incident phase. Serve as the primary owner and driver for complex changes, as a result of incidents post-mortem.

Nice to have:

• Experience with AI/ML and GPU clusters related threats.

• Familiarity with eBPF-based detection or runtime security tooling (Falco, Tetragon).

• Background in threat hunting.

Why this role at Nebius

• Build D&R at a company scaling from startup to global infrastructure provider in real time.

• Ability to evolve our internal D&R platform into a new cloud security product, delivering novel security observability for a range of neocloud customers - from big tech to AI startups.

• Work alongside world-class engineers on infrastructure that powers frontier AI.

• Competitive compensation with equity upside in a Nasdaq-listed, high-growth company.

• Flexible, remote-first culture.
