We are seeking an experienced Software Developer with strong C#/.NET expertise to develop software for warehouse and logistics systems deployed on industrial computing platforms.

This role focuses on building applications that run on industrial PCs (IPCs) and support real-time operations such as sortation, scanning, and system coordination. You will work on systems that integrate with hardware devices and backend platforms (WMS, databases, etc.). This is not a PLC/controls role.

You will be responsible for designing, developing, and deploying systems used in live warehouse environments.

Key Responsibilities

Design, develop, and maintain applications using C# and .NET (Core/6+)
Build software deployed on industrial PCs supporting warehouse/logistics operations
Interface with hardware devices such as scanners, cameras, and printers
Integrate with WMS, databases, and third-party systems
Write and optimize SQL queries
Troubleshoot and debug systems in live or test environments
Support system testing, deployment, and on-site validation
Work independently and collaborate with a small technical team

Required Qualifications

4+ years of professional experience with C# / .NET
Experience building applications for real-world operational systems (non-web-only)
Strong understanding of Windows-based systems
Experience with SQL (writing and debugging queries)
Ability to work with and modify complex existing codebases

Preferred Qualifications

Experience with warehouse/logistics systems (WMS, sortation, fulfillment, material handling)
Experience integrating with industrial devices (barcode scanners, vision systems, printers, etc.)
Experience with real-time or event-driven systems
Familiarity with TCP/IP, sockets, or REST APIs
Experience supporting software in field or operational environments

Additional Requirements

Willingness to travel occasionally to warehouse sites for testing and deployment

Application Question (Required)

Describe a system you have built or worked on that interacted with hardware or real-world operations (e.g., scanners, devices, industrial systems, or live operational environments). What was your role, and what challenges did you solve?

Why This Role

Build software used in live warehouse operations
Direct interaction with real-world systems and hardware
Small team with significant individual ownership
Opportunity to grow into a technical leadership role

Job Type: Full-time

Pay: $75,000.00 - $95,000.00 per year

Benefits:

Dental insurance
Health insurance
Paid time off
Professional development assistance
Retirement plan
Vision insurance

Application Question(s):

Are you a U.S. Citizen or Green Card holder and have been living in the U.S. for at least the last 5 years and have NOT traveled outside of the United States for more than 180 days in the last 5 years?
Describe a system you have built or worked on that interacted with hardware or real-world operations (e.g., scanners, devices, industrial systems, or live operational environments). What was your role and what challenges did you solve?
