Sr. Enterprise Engineer

Must be a US CITIZEN or Have a GREEN CARD

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.

Experience:

• Software Engineer: 8 years (Required)
• C++: 5 years (Required)
• C#: 5 years (Required)
• .NET: 5 years (Required)
• Version Control: GitHub: 5 years (Required)
• Infrastructure: Docker, Windows-based systems: 5 years (Required)
• C-Stores: 3 years (Preferred)
• Writing Payment Network Authorizers: 3 years (Preferred)

Benefits:

• 401(k)
• Dental insurance
• Flexible schedule
• Health insurance
• Paid time off
• Tuition reimbursement
• Vision insurance
