About the role

Job Description & Summary

For those who decode the future, not for everyone. 

  

We are for those who design solutions that don't just solve problems – they move industries forward. Who sees technology not as tools or platforms, but as invisible infrastructure behind strategy, performance and growth.   

  

This is a place where you will shape national resilience, lead innovation and guide clients through their most complex transformations. You will partner with decision makers to reimagine what’s possible – from operations and governance to sustainability and trust.   

  

You won't do it alone. You will work in high-performing, interdisciplinary teams where business fluency meets deep tech expertise. It's a constant value exchange: we give you the space, tools, and people to thrive – and you shape what comes next.   

  

For the builders, the disruptors, and the ones who troubleshoot with purpose and optimize with vision.   

Solve what others can’t. Grow as much as you dare. Belong in your own way. 

 

In this dynamic environment, we are looking for ambitious and self-driven Data Security Engineers to join our Tech & Data team.  You’ll work on high-impact projects, collaborate with industry leaders, and tackle real business challenges—all while learning, growing, and redefining what’s possible.

  • Configure and manage Data Loss Prevention (DLP), Information Protection (MIP), sensitivity labels, retention labels, and eDiscovery policies to ensure regulatory compliance and protection of business-critical information.
  • Implement Microsoft Defender for Cloud Apps (MCAS) or similar CASB to monitor user activities, detect anomalies, and enforce real-time session controls for sanctioned and unsanctioned SaaS applications.
  • Collaborate with compliance, legal, and data governance teams to define classification taxonomies and map them to security controls within Microsoft Purview and related E5 capabilities.
  • Perform technical implementation of security features such as multifactor authentication (MFA), Conditional Access, Identity Protection, Privileged Identity Management (PIM), and Just-in-Time (JIT) access.

GROW AS MUCH AS YOU DARE.

  • Bachelor’s degree in Computer Science, Cybersecurity, Information Technology, or a related field.
