Sr. Enterprise Engineer
ResultStack LLC, Florida, NY, United States
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.
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
