Expert knowledge of cybersecurity and proficiency in one or more MXDR technologies.
Ability to analyze and interpret complex data.
Strong leadership and communication skills.
Client engagement and problem-solving skills.
Written and spoken English proficiency.
At least one industry-recognized certification, such as CISM, Splunk Certified Admin, relevant Microsoft certificates, or CompTIA.

Responsibilities

Deploy, implement, configure, and support MXDR solutions for customers.
Operate independently in multidisciplinary project teams, contribute proactively to client deliverables, and address 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 MXDR services through automation, process enhancements, and knowledge sharing.
Assess customer needs, collaborate with stakeholders across organizational levels, and help make customer environments safer and more resilient against threats.
Support the SOC in interpreting logging associated with Splunk alerts, troubleshoot CrowdStrike agent CPU spikes during digital forensics and incident response (DFIR) engagements, and assist service delivery managers (SDMs) with technical questions.
Engage confidently with clients in person and digitally.

Desired Qualifications

Familiarity with Microsoft Sentinel, Splunk, CrowdStrike, or SentinelOne.

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.
