About the role

A semiconductor technology company is seeking a Principal Package Assembly Engineer to drive advanced packaging development. You will lead assembly process design and work closely with internal teams and external partners to deliver high-performance and scalable solutions for next-generation products.

What you’ll do

• Develop end-to-end package assembly and test processes for advanced packaging (2D/3D, heterogeneous integration)
• Define package architecture with DFT / DFM / DFR considerations
• Collaborate with OSATs and vendors to drive process development, yield improvement, and manufacturability
• Design and manage test vehicles to support validation and process optimization
• Plan and execute DOE, analyze results, and improve process performance
• Identify reliability risks (thermal/mechanical) and implement effective solutions
• Support product transition from development to mass production
• Work on emerging technologies such as co-packaged optics (CPO) and high-speed integration (plus)

What you bring

• 10+ years of experience in semiconductor packaging / assembly / process development
• Strong experience working with OSATs
• Hands-on experience in 2D/3D packaging or heterogeneous integration
• Familiarity with emerging packaging trends (e.g., Photonics experience is a must)
• Experience in test vehicle design, DOE, and validation
• Knowledge of thermo-mechanical and reliability challenges
• Strong problem-solving and cross-team communication skills

What’s on offer

• Opportunity to work on advanced packaging and next-generation integration technologies
• Collaborative and fast-paced engineering environment
• Flexible working model
• Competitive compensation and benefits
