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. We’re looking for someone with experience with SIEM & EDR tools. We see MXDR as Microsoft Sentinel, Splunk, CrowdStrike or Sentinel One. Familiarity with these platforms is a strong plus.

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.

Key Responsibilities

Implement and support MXDR solutions for customers, ensuring effective deployment and configuration.
Independently operate in multidisciplinary teams for projects, proactively contributing to client deliverables and addressing internal and external technical and organizational challenges.
Serve as a Subject Matter Expert on specific MXDR tools, supporting and advising customers and colleagues across teams.
Continuously improve the MXDR services through automation, process enhancements and knowledge sharing.
