Full Job Description

Position Overview

We're looking for a mid-level Software Developer (C#/.NET) to join our small but highly capable technology team to support and enhance the tech ecosystem powering our retail, distribution, and third-party logistics companies. Approximately 80% of your time will be focused on application and API development, with the remaining 20% dedicated to supporting system integrations, data accuracy, and day‑to‑day operational needs.

You'll work across multiple business domains to ensure our ERP (Microsoft Dynamics Business Central), POS (Counterpoint), and internal applications stay reliable, accurate, and well‑connected. If you are a self-starter, enjoy solving real business problems, improving data flows, and working with systems that directly impact daily operations, this role will feel like home.

This is a standard business‑hours role located on-site with no on‑call requirements.

Position Requirements

Required

3+ years of experience in C#/.NET development.
2+ years designing, building, and maintaining RESTful APIs.
Strong SQL Server skills (queries, stored procedures, performance considerations).
Experience troubleshooting complex systems or data-flow issues.
Ability to optimize performance-critical code.
Ability to understand and work within an existing codebase.
Comfortable working with ERP or POS systems (any platform).

Preferred

Experience with Microsoft Dynamics Business Central.
Experience with the AL Development Language.
Experience with Counterpoint POS or similar retail systems.
Background in refactoring or modernizing large codebases incrementally.
Proficiency with Git, Visual Studio, and Visual Studio Code.
Understanding of system architecture, integration patterns, and data‑flow design.
Familiarity with SSRS, ETL processes, or data synchronization pipelines.
Website development experience (JavaScript, HTML, PHP)
Shopware extension development (Python, Twig)
Working knowledge of Docker
Strong customer-service and communication skills
Ability to work independently and collaboratively within a team
Experience using JIRA, Microsoft Planner, or similar project-management tools.

Principal Duties & Responsibilities

General

- Optimize complex systems and performance-critical code.
- Maintain, enhance, and support existing software applications and core system components.
- Write clean, efficient, and maintainable C# code in a collaborative environment.
- Build automation workflows to reduce manual processes and improve data flow.
- Participate in code reviews and contribute to engineering best practices.
- Collaborate with QA, product managers, and other developers to deliver reliable solutions.
- Stay up to date with relevant tools, technologies, and development practices.

Application/API Development

- Develop and maintain C#/.NET RESTful APIs used for order management, inventory, pricing, and logistics workflows.
- Implement new features that integrate cleanly with Business Central, Counterpoint, and internal systems.
- Build and maintain data synchronization processes such as item data between distribution and retail, sales data from Counterpoint POS to Business Central ERP

Reporting and Data

- Create and maintain SSRS reports for sales, inventory, purchasing, and operational metrics.
- Investigate and correct data discrepancies across ERP, POS, and internal systems.

Architecture, Documentation, and Support

- Troubleshooting, debugging, and analysis of issues.
- Design and implement new features that integrate smoothly with current systems.
- Document software designs, processes, and key technical decisions.
- Work closely with technical support teams to troubleshoot bugs and resolve client/system issues.
- Work with business teams to understand operational workflows and translate them into technical solutions.
- Provide clear, reusable helpdesk documentation for recurring issues.
