Principal Test Engineer

Role overview

Test strategy and planning

• Define production test strategy and manufacturing test flow, including tester selection.
• Own test planning and provide testability input to DFT, DFM, and design reviews before tapeout.
• Define detailed test plans covering ATE implementation.

Test hardware and software

• Lead development of loadboards, probe cards, sockets, interface hardware, and related fixtures.
• Develop and review ATE test programs, test methods, production patterns, and supporting software.
• Lead first-silicon ATE bring-up, test program debugging, and sample generation.

Characterization and qualification

• Execute ATE characterization across process, voltage, and temperature conditions.
• Support qualification and customer sample generation with dedicated test programs.
• Identify test coverage gaps and potential escapes, then implement containment and corrective actions.

Production release and optimization

• Release qualified test software and hardware into production and support OSAT manufacturing start-up.
• Drive production ramp readiness reviews and close test-related release risks.
• Reduce test time through method optimization, improved sequencing, multisite efficiency, and instrumentation utilization.
• Support customer-return and RMA investigations by reproducing failures and assessing test coverage.

Qualifications

• Bachelor's or Master's degree in Electronics Engineering, Electrical Engineering, or a related discipline.
• At least 15 years of relevant semiconductor test engineering experience spanning NPI, characterization, qualification, production release, and sustaining support.
• Strong knowledge of semiconductor production test methodologies and practical ATE solution development.
• Experience with Teradyne J750HD, Advantest V93000, or an equivalent ATE platform.
• Experience developing production test solutions for SoC or MCU products.
• Experience with test hardware development and OSAT manufacturing release.
• Experience with data analysis and yield management tools such as JMP, PDF Exensio, Python, or equivalent platforms.

Leadership skills

• Provide technical direction and sign off reviews.
• Lead technical decisions and risk resolution across cross-functional teams.
• Operate independently as a recognized subject-matter expert.
• Influence teams without direct authority and communicate clearly with stakeholders.
