## About the Role

* Associate's or Bachelor's degree in Computer Science, Information Systems, Engineering, or a related field or equivalent practical experience (bootcamp, military, self-taught with a portfolio we can look at)
 * Working knowledge of SQL: you can write a multi-table join, understand what an index does, and know why SELECT * in production code is a bad habit
 * Familiarity with at least one object-oriented language - C# preferred, but Java, Python, or VB.NET experience transfers
 * Basic understanding of how REST APIs work: requests, responses, JSON, status codes, authentication
 * Basic familiarity with source control (Git/GitHub)
 * Clear written and verbal communication - much of this job is asking a non-technical person the right question
 * Curiosity and initiative: you research before you escalate, and you flag problems early rather than hoping they go away

Coursework, internships, co-ops, and personal projects all count. If you've built something you're proud of, tell us about it.

Helpful, not required - we'll teach you these

 * Python beyond the basics, especially for data or automation work
 * Any hands-on work with LLM APIs, MCP, RAG, or embeddings - including personal projects
 * Experience using AI coding assistants on real code, and the judgment to review what they produce
 * Docker or other containerization
 * Power BI, DAX, or other BI and reporting tools
 * React or another modern front-end framework
 * ERP development experience (Infor SyteLine / CloudSuite Industrial a plus)
 * EDI or other B2B partner integration experience
 * Exposure to distribution, manufacturing, inventory, or warehouse systems
 * Aviation or other regulated-industry experience

## Description

* Write, test, and tune T-SQL queries, views, stored procedures against our ERP and line-of-business databases
 * Build and maintain C#/.NET applications and services
 * Build and consume REST APIs - the integrations that connect our core business systems to each other and to outside partners. This is core to the job, not a side task.
 * Work on our AI integration efforts - connecting LLM APIs and MCP (Model Context Protocol) servers to business data, so the business can ask real questions of real systems
 * Write Python for data work, automation, and AI-adjacent tooling
 * Support and enhance internal web applications
 * Work in containerized development and deployment environments
 * Work directly with people in purchasing, warehouse, sales, and finance to understand what they actually need before you build it
 * Follow source control, code review, and change management practices and help us improve them, Microsoft SQL Server, T-SQL, stored procedures, indexing and query tuning
