Who we are and what we do
NN’s CDC Core team keeps our business and customers safe. We monitor and analyze cyber-security alerts around the clock and react swiftly to any suspected threats. As we grow, we’re looking for an experienced Level 2 Security Analyst, someone already succeeding in a similar role, who can bring fresh ideas, mature skills and immediate added value to our team.
What you will work on
You’ll independently handle daily cyber-security operations, safeguarding NN’s environment and ensuring we stay one step ahead of adversaries.
Be a key member of our frontline cyber-security team, detecting and responding to advanced threats across NN’s global environment
Own the end-to-end triage and investigation of security incidents, initiating and driving incident response actions with minimal supervision
Maintain and continuously improve our detection logic, playbooks and internal process documentation, sharing lessons learned with the broader team
Collaborate with infrastructure, cloud and application teams, building strong relationships and delivering expert security guidance
Support and mentor junior analysts during complex investigations, raising the overall capability of the SOC
Assist with maintenance and fine-tuning of our SIEM, EDR, NDR, UBA and IDS/IPS tooling, working closely with senior engineers
Contribute proactively to ad-hoc security projects, purple-team exercises and technology upgrades
What we’re looking for
We need a proven Security Analyst who can hit the ground running and elevate our detection and response maturity from day one.
2–4 years of hands-on SOC experience (or similar blue-team role) with demonstrable incident response success
Solid grasp of ISO/OSI layers, TCP/IP networking, Windows/Linux internals and Active Directory security
Working knowledge of security frameworks such as Cyber Kill Chain and MITRE ATT&CK, and the ability to apply them during investigations
Proficiency with modern SOC tooling—e.g., Splunk, Microsoft Sentinel, Defender, CrowdStrike, Darktrace, Suricata, etc.
Ability to craft hypotheses, hunt for threats and validate findings using SIEM queries, EDR telemetry and packet analysis
Clear, concise communicator who builds trust with technical and non-technical stakeholders
Scripting familiarity (Python, PowerShell or Bash) and a continuous-improvement mindset are strong pluses
Bachelor’s degree in Computer Science, Cyber Security, or related technical field (or equivalent practical experience)

How does our hiring process work?
What happens after you hit “Apply”? First, our team will carefully review your CV to see how your skills and ambitions line up with the role. If there’s a good match, Veronika from HR will get in touch to arrange a brief technical pre-screen, where you’ll chat with a couple of seniors. Should everyone feel the chemistry, we’ll invite you to a longer - yet still meaningful - interview. In that session you’ll meet the team manager and Veronika, and you’ll dive a bit deeper into technical topics. If everything clicks on both sides, that’s it - we’ll be thrilled to welcome you aboard!
