Senior OSAT Engineer

About This Opportunity

We are representing a confidential global semiconductor organization seeking a Senior OSAT Engineer to join their expanding backend manufacturing operations in Taiwan. Our client is a leader in programmable logic solutions serving data center, communications, automotive, aerospace, and industrial sectors.

This is a permanent, full-time position requiring deep expertise in outsourced assembly and test engineering across a global supplier network. You will drive new product introduction readiness, yield optimization, cost improvements, and qualification activities for advanced packaging and test flows supporting next-generation programmable devices.

Responsibilities

• Lead technical engagement with OSAT suppliers on assembly and test process development, yield ramp, quality improvement, and volume manufacturing readiness
• Drive new product introduction (NPI) from engineering builds through production release, ensuring OSAT capability meets electrical, thermal, and mechanical requirements for complex programmable devices
• Optimize packaging and test architectures for performance, cost, and reliability including advanced packaging, flip-chip BGA, high-pin-count packages, substrate technologies, wafer-level solutions, and burn-in/final test coverage
• Monitor and improve manufacturing performance using data-driven analysis; identify systemic issues and lead root cause and corrective actions
• Partner with Test Engineering, Package Design, Product Engineering, DFM, and Quality teams on process optimization, failure analysis, and manufacturability improvements
• Implement and maintain process control systems, SPC methodologies, automation improvements, and lean manufacturing principles at OSAT facilities
• Support cost reduction initiatives including BOM optimization, process simplification, and cycle time improvements
• Track supplier performance metrics (yield, DPPM, cost, cycle time, OEE) and provide updates with risk assessments and mitigation plans
• Lead or support reliability testing and package qualification activities aligned to industry standards (JEDEC, IPC, AEC-Q)
• Maintain strong technical relationships and communication cadence with OSAT partners to ensure transparency, collaboration, and escalation management

What We're Looking For

Required:

• Bachelor's degree in Electrical Engineering, Materials Science, Mechanical Engineering, or related field
• 10+ years of semiconductor assembly, packaging, or test engineering experience
• Hands-on experience with OSAT manufacturing environments, including wafer finishing, substrate attach, interconnect packaging, test, and burn-in
• Strong technical understanding of backend manufacturing flows: flip-chip, wire bond, underfill, molding, final test, reliability stress and analysis
• Proven ability to analyze yield, reliability, and cost data to drive engineering decisions and improvements
• Demonstrated success working with international suppliers and cross-functional teams
• Strong statistical analysis, written and verbal communication skills, including technical reporting and supplier engagement

Preferred:

• Backend experience with programmable devices, ASICs, or SoCs, particularly high-pin-count or high-power devices
• Experience in automotive or high-reliability product qualifications (AEC-Q / ISO standards)
• Familiarity with advanced packaging: 2.5D/3D, fan-out WLP, heterogeneous integration
• Knowledge of supply chain risk mitigation, dual sourcing, and volume scaling strategies
• Experience with automation, traceability systems, and smart factory/manufacturing analytics
