<div class="content-intro">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.</div><h3>The role</h3> Nebius is looking for a Lead Detection Engineer.This is an individual contributor role with full technical ownership. You'll set the direction for detection engineering: the standards, the tooling, the coverage strategy, and the automation that operationalizes it all. You'll work closely with SOC analysts and Platform Engineering to make detection a first-class engineering discipline. You’re welcome to work in our offices in Tel Aviv, Israel Your responsibilities will include:  <ul> <li>Detection coverage strategy across endpoint, identity, cloud, and infrastructure — how it's measured, prioritized, and continuously improved. </li> <li>Detection-as-Code pipeline: version control, testing, peer review, CI/CD, and deployment practices for all detection logic. </li> <li>Architecture connecting detections to enrichment, triage, and automated response workflows. </li> <li>Technical standards for how detections are designed, tested, documented, deployed, and retired. </li> <li>Detection quality: fidelity metrics, false positive reduction, coverage measurement, and continuous validation loops. </li> <li>Design and build high-fidelity behavioral detections across SIEM and EDR platforms. </li> <li>Research emerging attacker techniques and translate threat intelligence into scalable, evasion-resistant detections. </li> <li>Validate detections through threat simulations and continuous detection testing. </li> <li>Partner with SOC analysts to close the feedback loop between detections and real investigations. </li> <li>Define and track detection engineering metrics; communicate coverage posture and effectiveness to security leadership. </li> <li>Make architectural decisions that scale as the team and organization grow. </li> </ul> We expect you to have:  <ul> <li>Minimum 3 years in detection engineering, security operations, or a hybrid offensive/defensive role — with demonstrated depth, not just breadth. </li> <li>Experience owning or leading detection engineering work as a senior technical contributor<s
