About the Role

This is not a traditional helpdesk role. We are looking for someone who can operate as the final escalation point for complex technical issues, perform deep root-cause analysis, and take ownership of critical customer-facing systems.

The successful candidate will have extensive experience across infrastructure, networking, operating systems, hardware, databases, cloud technologies, and enterprise troubleshooting. They will be comfortable diagnosing issues that others cannot solve and will work closely with internal teams, customers, and third-party vendors to identify and implement permanent solutions.

This role is ideal for someone who enjoys solving complex technical challenges, improving system reliability, and driving technical excellence across the business.

Continuous Improvement

Identify recurring technical issues and implement preventative solutions.
Create and maintain technical documentation, knowledge base articles and troubleshooting guides.
Recommend improvements to system architecture, monitoring and operational processes.
Work alongside development and product teams to identify software defects and operational risks.

Customer & Field Support

Join customer calls as the technical subject matter expert.
Conduct site visits where hands-on troubleshooting or implementation support is required.
Build strong relationships with key customer stakeholders through technical expertise and professionalism.

Understanding of cybersecurity best practices and endpoint security.

Problem Solving

Proven ability to independently diagnose and resolve complex technical issues.
Strong analytical mindset with a methodical troubleshooting approach.
Ability to manage multiple high-priority issues simultaneously.
Demonstrated experience implementing permanent fixes rather than temporary workarounds.

Communication
