Thales’s Security Analyst Team is tasked with tackling and solving our most complex field issues for enterprise customers. As a Security Analyst, you will be analysing large amounts of traffic to websites to find correlations and patterns. Based on the conclusions drawn from the analysis, the analyst collaborates with the customer and with Thales’s internal teams to implement mitigation strategies to stop automated website attacks.
An important part of the position is to work with clients, investigate anomalies, and provide easily consumable but detailed evidence for all actions taken. A degree of flexibility to take appointments evenings and mornings required.
We’re part of a global team operating on a follow-the-sun model, so although we cover all time zones, you’ll be working with the EMEA region.
Most of the team is based in Belfast, UK, with one analyst currently in Sweden and one in Israel. This is a hybrid position with on-site required during the training period.
