About Nebius

Launched in November 2023, the Nebius platform provides high-end infrastructure and tools for training, fine-tuning and inference. Based in Europe with a global footprint we aspire to become the leading AI cloud for AI practitioners around the world.

Nebius is built around the talents of around 400 highly skilled engineers with a proven track record in developing sophisticated cloud and ML solutions and designing cutting-edge hardware. This allows all the layers of the Nebius cloud – from hardware to UI – to be built in-house, differentiating Nebius from the majority of specialized clouds. As a result, Nebius customers get a true hyperscaler-cloud experience tailored for AI practitioners.

As an NVIDIA preferred cloud service provider, Nebius offers the latest NVIDIA GPUs including H100, L40S, with H200 and Blackwell chips coming soon.

Nebius owns a data center in Finland, built from the ground up by the company’s R&D team. We are expanding our infrastructure and plan to add new colocation data centers in Europe and North America already this year, and to build several greenfield DCs in the near future.

Our Finnish data center is home to ISEG, the most powerful commercially available supercomputer in Europe and the 19th most powerful globally (Top 500 list, June 2024). It also epitomizes our commitment to sustainability, with energy efficiency levels significantly above the global average and an innovative system that recovers waste heat to warm 2,000 residential buildings in the nearby town of Mäntsälä.

Nebius is headquartered in Amsterdam, Netherlands, with R&D and commercial hubs across North America, Europe and Israel.

The role

We are seeking an experienced Security Operations Team Leader to establish and lead our new Security Operations team. In this role, you will oversee day-to-day security operations, including monitoring, responding to incidents and proactively hunting for threats. You will also play a crucial role in reviewing access requests, managing firewall rules and ensuring our perimeter defences are strong. The ideal candidate is a hands-on leader with deep technical expertise and a proven ability to manage and mentor a security team while collaborating closely with other teams and business units.

In this position, your responsibility will be to:
  • Lead the process of reviewing and approving access requests to ensure adherence to the principle of least privilege.
  • Regularly audit access logs and permissions to maintain security compliance.
  • Manage and regularly review firewall rules to ensure they align with organizational security policies and protect against emerging threats.
  • Oversee and lead the security incident response process, coordinating investigation, containment, and remediation activities during security events.
  • Develop and maintain security incident response playbooks.
  • Implement and lead proactive threat hunting activities to identify and mitigate advanced persistent threats (APTs) or indicators of compromise (IOCs) within the environment.
  • Utilize SIEM and other security tools to identify unusual behaviors and potential risks not caught by automated systems.
  • Create and maintain dashboards tracking relevant vulnerability management metrics.
  • Develop and fine-tune security alerts based on evolving threats.
  • Manage regular perimeter scanning to identify potential vulnerabilities in the organization’s external-facing assets.
We expect you to have:
  • Minimum of 5-7 years of experience in cybersecurity, with at least 2 years in a leadership or senior security analyst role.
  • Deep understanding of firewall management, SIEM platforms, intrusion detection/prevention systems (IDS/IPS) and endpoint protection tools.
  • Strong knowledge of incident response frameworks (e.g., NIST, SANS) and experience in handling critical incidents.
  • Experience with vulnerability management tools (e.g., Nessus, Qualys, Rapid7) and patch management processes.
  • Experience with network, Linux and application security practices.
  • Experience in detecting and mitigating advanced threats using behavioral analytics and threat intelligence.
  • Expertise in using tools such as Splunk or ELK Stack, and endpoint protection tools (EDR).
  • Knowledge of identity and access management (IAM) solutions (e.g., MS Entra ID, Teleport) and processes for least privilege enforcement.
  • Basic coding skills to be able to automate your work.
  • Project management and problem-solving experience.
  • Good written and verbal communication skills in English.
It would be a plus if you have certifications:
  • CISSP, CISM or GIAC GSOM certificates are considered a plus.
  • Certifications in incident response (e.g., GCIH, OSDA) are a plus.

We’re growing and expanding our products every day. If you’re up to the challenge and are excited about AI and ML as much as we are, join us!
