Sr. Enterprise Engineer

Sr. Software Engineer/Sr. Enterprise Engineer

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#,  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

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

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, Store Point), Gilbarco, Verifone, or similar systems

Languages:

C++, C#,.NET

Version Control:
Git Hub

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.
