Application Developer, Core Applications

Holley is building a modern, high-impact internal IT function—and we’re looking for an experienced Application Developer, Core Applications (Infor) who thrives on solving problems, improving user experience, and supporting the ERP (Syteline) that keeps the business running.

The Application Developer, Core Applications develops and supports business applications used across Holley, with a primary focus on the on-premises Infor SyteLine 9 ERP platform and its Microsoft SQL Server database. The role combines application support, technical analysis, and hands-on SQL development to deliver reliable solutions for manufacturing, distribution, finance, customer service, and other business functions.

This developer works directly with business stakeholders and the Core Applications team to translate requirements into maintainable technical solutions. The position also works closely with Data Engineering and the Database Administrator to support data integration, data quality, query performance, database standards, and controlled production deployments.

As Holley transitions from SyteLine to Infor LN, this role will help maintain the stability of the current ERP environment, preserve critical business logic, and support data analysis, conversion, validation, and migration activities.

Role Purpose

The Application Developer, Core Applications (Infor) translates approved business and functional requirements into reliable, secure, and maintainable technical solutions. The role designs, develops, tests, documents, and supports SQL code, SyteLine 9 customizations, reports, interfaces, background processes, and related application components. The developer maintains traceability from the original business requirement through solution design, development, testing, deployment, validation, and ongoing support.

The role also improves the stability, performance, and supportability of Holley’s core applications by applying development standards, participating in peer reviews, identifying technical and data-related risks early, and ensuring that delivered solutions remain aligned with business requirements. The developer works closely with Core Applications, Data Engineering, and the Database Administrator to support data integrity, query performance, integrations, controlled production deployments, and Holley’s transition from SyteLine to Infor LN.
