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.

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.

Problem Solving
