We are seeking a POS Support Engineer to support and maintain the point-of-sale and forecourt technology environment across a network of fuel and convenience retail sites. This is a hands-on technical role responsible for keeping payment, POS, and forecourt systems running reliably, troubleshooting complex issues across the store technology stack, and automating routine operations.

• Diagnose and resolve issues spanning POS applications, payment processing, network connectivity, and forecourt/dispenser integration.
• Develop, maintain, and improve Power Shell scripts to automate endpoint configuration, software deployment, monitoring, log collection, and routine maintenance tasks.
• Support Windows-based endpoints today and contribute to the planned migration of select endpoints to Linux (openSUSE), including testing, imaging, and configuration.
• Manage and support payment terminal estates via terminal-management tooling, including configuration pushes, firmware/software updates, and device health monitoring.
• Coordinate with vendors, payment processors, and internal teams to resolve escalations and implement changes.

• Strong Power Shell scripting skills — able to write, maintain, and troubleshoot automation scripts independently.
• Solid Windows endpoint administration and troubleshooting experience.
• Strong analytical and problem-solving skills across applications, OS, and network layers.
• Clear written and verbal communication; able to document work and coordinate with vendors and site staff.
