You’ll be working on our cutting-edge SMT (Surface Mount Technology) inspection systems, contributing to both existing and new Windows desktop applications that power our industry-leading products. Depending on your expertise, you will be matched with the right role within the team, and we’ll support your professional development through hands-on projects and cross-functional collaboration.

Key Responsibilities

• Develop and maintain desktop applications for Koh Young’s 3D inspection systems (AOI/SPI/AXI)
• Design and implement new features and resolve CRM-reported issues
• Collaborate with UX/UI, QA, and algorithm engineers to improve product quality and performance
• Support customer needs via short-term overseas business trips (2 days to 2 weeks when needed)
• Participate in team-wide architectural and design discussions

• Comfortable working with SQL Lite / MS-SQL, and handling network communication
• Familiarity with custom WPF controls, Prism, or SharpDX

Preferred Qualifications

• Experience in Windows OS internals or performance optimization
• Understanding or experience in the SMT domain (e.g. electronics manufacturing, inspection systems)
• Background in starting new software projects from scratch
• Familiarity with MFC, application performance tuning, or database schema design

• You’ll be part of a global leader in 3D inspection solutions (AOI, SPI, AXI)
• We value individual strengths — whether you’re a deep expert or a broad generalist
• Flexible matching to roles that suit your current capabilities with room to expand and evolve
• Opportunity to work on impactful projects with international collaboration
• Support for continuous growth and domain learning in SMT and inspection technology
