Job Overview
We are looking for a Sr. Software Engineer/Sr. Enterprise Engineer to help modernize and support legacy point-of-sale (POS) and fuel system software for a major retail technology platform.
This is a high-impact role focused on real-world systems that drive in-store transactions and fuel operations at scale.
You'll work primarily in C++, C#, and .NET environments, supporting and extending core business-critical platforms. This is not a web development role — it's ideal for engineers who enjoy deep systems work, modernizing legacy infrastructure, and solving problems in complex, high-volume environments.
What You'll Do
- 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
- What You Bring
- 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
Tools & Environment
- Languages: C++, C#, .NET
- Version Control: GitHub
- Infrastructure: Docker, Windows-based systems
- (Optional bonus stack: React, Node.js, AWS — exposure helpful but not required)
Why Join Us?
This is a unique opportunity to work on the software backbone of retail and fuel operations — where reliability, speed, and modernization have real-world impact. You'll be joining a small, experienced engineering team with full ownership of critical systems used nationwide.
If you enjoy solving problems, diving into complex software environments, and bringing older platforms into the future — we'd love to hear from you.
