Senior Test Engineer

u-blox

Thalwil, Switzerland

As a Senior IC Test Engineer, you will take a leading role in developing, integrating, and optimizing test solutions for IC validation and high-volume production. You will drive test strategy from early development through mass production, ensuring high test coverage, robustness, and cost efficiency.

In addition to hands-on technical contributions, you will provide technical leadership, mentor junior engineers, and act as a key interface between design, product, and production teams.

Your Responsibilities

Technical Leadership & Strategy

Define and drive test strategy and architecture across validation and production phases
Own test solution development from concept through product ramp and yield optimization
Lead complex debug and FA activities across silicon, hardware, and software
Ensure test coverage, quality, and cost targets are met across product lifecycle
Identify and implement test cost reduction and throughput optimization

Test Development & Integration

Design and develop advanced test hardware (load boards, probe cards) for validation and production
Architect and develop scalable test programs and automation frameworks
Lead integration of ATE platforms (e.g., Advantest, Cohu) with standardized and custom test solutions
Define characterization plans and ensure robust correlation between lab and ATE

Data Analysis & Yield Improvement

Analyze test results and failures to improve test procedures, coverage, and product reliability
Drive yield improvement, binning strategy, and test limit optimization
Establish methodologies for data-driven decision making and continuous improvement

Cross-functional Collaboration

Collaborate closely with Design, Quality, and Production Engineering teams
Influence design-for-testability (DFT) and product design decisions
Ensure seamless handover from development to production and support manufacturing ramp

Mentorship & Knowledge Sharing

Mentor junior engineers and provide technical guidance
Promote best practices in test development, debug, and documentation
Contribute to continuous improvement of tools, methodologies, and workflows
