Qualifications
- 8+ years of professional software engineering experience
- Strong hands-on experience with C++ and/or C# (.NET)
- 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
- Bonus: Experience with NCR platforms (Radiant, R10, StorePoint), Gilbarco, Verifone, or similar systems
Requirements
- Software Engineer: 8 years (Required)
- C++: 5 years (Required)
- C#: 5 years (Required)
- .NET: 5 years (Required)
- Version Control: GitHub: 5 years (Required)

- Writing Payment Network Authorizers: 3 years (Preferred)
Benefits
