Sr./Staff Manufacturing Engineer

Location: TWN - Remote

Time Type: Full time

Job Description

Key Responsibilities:
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
