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
