PROFILE

Academic background & Experience

Engineering degree (Master’s level or equivalent) in computer science, cybersecurity, information sciences, or a related field. Specialization in Threat Intelligence, threat analysis, or offensive security (e.g., via a Master’s in cybersecurity or certifying programs from ENISA or Romanian universities such as the Polytechnic University of Bucharest) would be a major asset. Continuous training in cybersecurity (MOOCs, bootcamps) is appreciated to demonstrate ongoing skill updates.

At least 3 years of experience in a similar cybersecurity role, ideally within a CSIRT, SOC, or Threat Intelligence team. Proven expertise in Threat Intelligence is essential: you must have hands-on experience in monitoring and analyzing TTPs of cyber threat actors, enriching IoC, and producing actionable reports based on intelligence data.
