Job Description

Description

As a Senior MXDR Engineer, you are a true multitasker with both technical depth and strong communication skills. Deploying and maintaining MXDR solutions is your core responsibility - your "bread and butter." You assess customer needs, collaborate with stakeholders across organizational levels, and ensure their environments become safer and more resilient against threats. 

Your expertise is also a trusted resource within the team. Whether it's helping the SOC interpret the logging associated with a Splunk alert, troubleshooting CPU spikes of CrowdStrike agents during a DFIR engagement, or assisting SDM in interpreting technical questions - you’re the go-to person. 

This role requires a broad skill set. A major focus is on technical consultancy, meaning a strong technical foundation, professional communication skills, and a passion for continuous learning are essential.

Because this is a customer-facing role, you should feel confident engaging with clients in both in-person and digital environments. As part of a global organization, proficiency in written and spoken English is a must.
