Detection Engineering & Response Lead

About Nebius:

Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.

Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

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: achieve full MITRE coverage, 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 engin
