About this role

Location: New Taipei City

Sustain production test operations for SPP Silicon Photonics products (LIP, Burn-In, ECL test flows) at the supplier in Taipei, ensuring stable throughput, yield, and quality; own the day-to-day technical interface with supplier engineering, resolving test issues through root cause analysis and corrective action (30%).
Monitor and improve production metrics – yield, throughput, retest rate, and cycle time; lead SPC implementation and continuous improvement initiatives; manage hold-lot disposition for production-line quality events and lead customer-return RMA (20%).
Drive automation and process standardization – convert currently manual, tribal-knowledge processes (pick-and-place packaging, optical alignment, light coupling) into documented, automated, and scalable production; build and maintain test-procedure documentation (X/Y/Z stage calibration, laser-path tuning, recipe management) and release into Semtech AgilePLM (20%).
Support customer test-data requirements – test data integrity, e-data delivery, and shipment quality; partner with Semtech IT and customer counterparts on automated test-data transmission and API integration to customer systems (15%).
Support test capacity ramp planning, including qualification of new test equipment (BI, LIP, ECL, gain test); provide regular status updates on open initiatives to the internal management team and key customers (15%).

Minimum Qualifications:

Bachelor’s or Master’s degree in Electrical Engineering, Photonics, Optical Engineering, Physics, or a related discipline.
5+ years of test engineering experience, with at least 2 years in Silicon Photonics, optoelectronic device, or laser diode test.
Hands-on experience with LIV/LIP test, burn-in, and optical characterization equipment (Optical Spectrum Analyzer, photodetector, Source Measure Unit).
Strong working knowledge of semiconductor production test fundamentals: yield monitoring, SPC, root cause analysis, and hold-lot disposition.
Strong English communication skills, both written and verbal, for working with Semtech HQ and global customers.
Desired Qualifications
Experience working with OSATs or contract manufacturers in a production sustaining role.
Familiarity with optical alignment, manual probing, and laser characterization techniques.
Knowledge of optical transceiver components and architectures (TIA, CDR, GainChip, EML, DML, coherent modules).
Self-motivated and able to work independently with minimal supervision while multi-tasking across projects.
Self-starter who operates effectively in a transition or acquisition environment with incomplete documentation.
Strong problem-solving and analytical mindset with a bias toward action.
Customer-facing maturity and professionalism in technical communication.
Comfortable balancing hands-on technical work with cross-functional coordination.
Team player with mentoring and training capability.

Level of Authority:

Directs test engineering operations for major business divisions
Makes decisions regarding test strategies, technology selections, and resource allocation
Approves significant test architectures and methodology changes
Influences executive decisions on matters affecting product quality and
test investments
Manages substantial test engineering resources and improvement initiatives
Represents test engineering function in senior leadership forums

Job Complexity:

Addresses highly complex test challenges requiring strategic vision and innovative solutions
Balances competing priorities across multiple stakeholder groups and business units
Navigates ambiguous technical situations with minimal guidance
Develops comprehensive strategies to address unprecedented test challenges
Requires deep understanding of semiconductor device characteristics, technology trends, and business operations
Expected to anticipate emerging test requirements and position function for future success
