MES Developer

Position Summary  The Application Developer builds and maintains the software that keeps MES running day to day — features, bug fixes, reports, and automation scripts. You'll work under MES Engineering direction on well-scoped tasks, with plenty of room to grow into system design and equipment integration work as you build experience. This is a strong fit if you want serious hands-on software development experience in a manufacturing environment, without yet owning system architecture or on-call escalation.  Responsibilities  Application Development  • Implement new features and enhancements to existing MES modules — lot tracking, production transactions, reporting screens, user-facing tools  • Fix bugs and handle first-line troubleshooting for MES application issues, escalating architecture-level or multi-system problems to MES Engineering  Database & Reporting  • Write and maintain SQL queries, stored procedures, and reports against Oracle and/or MS-SQL  • Build data-processing functions and support ad hoc data requests from Manufacturing and Quality teams  • Learn and apply PL/SQL patterns used across the existing codebase  Integration & Automation  • Implement EDI interfaces and data integration functions following existing integration patterns set by MES Engineering  • Develop automation scripts and tools to streamline manufacturing, reporting, or operational tasks  • Get exposure to SECS/GEM and equipment interface work by shadowing and assisting on integration projects  Quality & Process  • Perform code reviews, manage version control, and keep the codebase maintainable  • Write test plans and execute unit, integration, and user acceptance testing  • Support production validation after releases and deployments  • Maintain user-facing documentation, support guides, and troubleshooting notes for common issues  Collaboration  • Participate in sprint planning, standups, and release planning with the Application Team  Requirements  • Bachelor's Degree in Engineering, Computer Science, Information Technology, or related field  • 2–3 years of software development experience; MES or manufacturing exposure is a plus but not required  • Proficiency in C, C#/.NET, ASP.NET; working knowledge of C++ and Python  • Working SQL skills (Oracle and/or MS-SQL): writing queries, basic stored procedures, debugging data issues  • Comfortable reading and extending existing code written by others  • Willingness to learn manufacturing processes (lot/wafer/panel tracking, production transactions) on the job  • Good written communication — you'll be documenting what you build for both technical and non-technical audiences  Preferred  • Exposure to system interfaces, APIs, or EDI  • Any exposure to SECS/GEM or equipment integration, even coursework or personal projects  • Interest in growing toward MES architecture and system design over time  • Semiconductor or manufacturing environment familiarity
