Senior Software Engineer – POS Modernization

📍 Remote (U.S. Only) | Full-Time | Immediate Start

We’re looking for a Senior Software 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.

• Modernize and support store-level POS and fuel control systems

• 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

• 5+ 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

• Languages: C++, C#, .NET

• Version Control: GitHub

• Infrastructure: Docker, Windows-based systems

• (Optional bonus stack: React, Node.js, AWS — exposure helpful but not required)

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.
