Position: Senior Software Engineer (C++ stack) for Semiconductor Equipment Control – FAB Feature Integration (MFC/Qt)

As a Senior Software Engineer for semiconductor equipment control software, you will be involved in the full software engineering lifecycle, including requirements, design, implementation, testing, analysis, and maintenance, with a growth path towards technical leadership. This role is focused on FAB feature integration and delivery, primarily using C++, and building/integrating desktop and engineering tooling using MFC/Qt.

Your responsibilities include:

• Collaborate with architects and tech leads to define design decisions and interfaces within your domain (e.g., module boundaries, integration interfaces, dependencies).
• Perform requirement analysis and deliver feature integration in FAB environments.
• Implement and test software features; support integration, regression, debugging, and maintenance.
• Conduct peer reviews and follow quality practices to ensure maintainability and delivery readiness.
• Work as part of a Scrum/Agile team, delivering user stories across the stack and collaborating with cross-functional members.

The Job Scope

In practice, you will mainly work on:

• Desktop and engineering tooling and UI integration using MFC/Qt.
• Aligning with the broader equipment control software context (e.g., host interfaces such as SECS/GEM and EDA, simulation/testing environments, and a layered architecture).

Technically, this role focuses on developing testable, maintainable, high-quality semiconductor equipment control software features, primarily in C++, and delivering feature integration in FAB environments. In practice, you will mainly work on desktop and engineering tooling and UI integration using MFC/Qt, while aligning with the broader equipment control software context (e.g., host interfaces such as SECS/GEM and EDA, simulation/testing environments, and a layered architecture).

Specifically, the job scope covers the following layers and integration points:

• Hardware Abstraction Layer (HAL): enable programmable access to equipment components.
• Devices / Domain layers: model module behavior and state machines; integrate across module boundaries.
• Application layer: support higher-level functions such as recipe management and calibration.
• UI / HMI layer: implement and integrate on-site engineering tools and desktop UI using MFC/Qt.
• Simulation & Testing: leverage system/unit testing and simulators to validate integration and regressions.
• Host Interfaces: collaborate around SECS/GEM, GEM300, and EDA / Interface A as needed to ensure FAB usability.

Job requirements

QUALIFICATIONS AND EXPERIENCE

• Bachelor’s degree or above in Computer Science, Software Engineering, Automation, or a related field.
• Experience in equipment control or industrial software development is a plus.
• Strong C++ object-oriented programming skills; familiarity with the C++ standard library (STL).
• Desktop UI and engineering tooling experience using MFC and/or Qt.
• Familiar with git workflows and continuous integration (CI) tools.
• Experience working in Agile/Scrum or Kanban teams.

DESIRABLE SKILLSET

• Understanding of factory software context (e.g., Host/EAP, SECS/GEM, EDA) and related integration scenarios.
• Strong system integration and on-site debugging capability in FAB integration contexts.
• Experience with unit testing and TDD/BDD practices (e.g., xUnit, Boost.Test, reqnroll).
