• Experience working on or modernizing legacy enterprise systems, ideally in retail, fuel, or POS industries
• Familiarity with hardware integration (e.g., payment terminals, barcode scanners, fuel pumps)
• Self-starter mindset with the ability to take ownership of legacy-to-modernization projects

Nice To Haves

• Experience with NCR platforms (Radiant, R10, StorePoint), Gilbarco, Verifone, or similar systems

Responsibilities

• Modernize and support store-level POS and fuel control systems
• Payment Authorization Flow
• Translate legacy software into modular, maintainable code
• Troubleshoot production issues across hardware/software integrations
• Collaborate with engineers and product managers to scope modernization efforts
• Participate in code reviews, platform documentation, and refactoring legacy components
• Support system reliability and performance in high-transaction retail environments
