From security engineering and cloud security to incident response, threat intelligence, automation, and offensive security, this role offers technical breadth.

• The cloud security knowledge. You have hands-on experience securing cloud environments, including Azure, Entra ID, AWS, and SaaS platforms. You understand modern identity, infrastructure, and cloud security principles and can implement and continuously improve security controls across complex technology environments.

You are comfortable analyzing threat intelligence, understanding attacker tactics, techniques, and procedures (TTPs), and applying that knowledge within a security operations environment.
• The ownership mindset. You thrive in environments where you are trusted to define priorities, solve complex problems independently, and take ownership of meaningful initiatives. You are naturally curious, proactive, and comfortable working with a high degree of autonomy.
• The communication skills. You communicate effectively with technical and non-technical stakeholders, building strong relationships across Security Operations, Engineering, and leadership teams. You can mentor others, collaborate across functions, and communicate complex technical concepts in a clear and practical way.
• The commitment to continuous learning. You enjoy keeping pace with new technologies, evolving cyber threats, and emerging security practices. You are motivated to continually expand your knowledge and apply new ideas to strengthen security capabilities.
