ATE Test Development Engineer (Cohu DxV)

• We are seeking experienced ATE Test Development Engineers to support mixed-signal IC validation and production test development initiatives. This role will focus on advanced ATE solutions using the Cohu DxV platform, with contributions across multiple programs.

• The ideal candidate will have strong expertise in mixed-signal semiconductor testing, deep hands-on experience with Cohu DxV, and the ability to operate across both modern and legacy test systems.
  
  

Key Responsibilities:

• Develop, debug, and optimize ATE test programs for mixed-signal ICs

• Lead test development on Cohu DxV platform (primary “workhorse” ATE system)

• Support validation and production test

• Collaborate with design, validation, and product engineering teams to ensure test coverage and quality

• Perform characterization, correlation, and yield improvement activities

• Support test migration and coexistence between legacy and modern ATE systems

• Develop documentation for test methods, hardware interfaces, and program flows
  
  

Required Technical Skills:

ATE Platform Expertise (Critical)

• Strong hands-on experience with Cohu DxV (required)

• Familiarity with multi-site, high-throughput test architectures

Experience in:

• Test program development and debugging

• Device interface board (DIB) bring-up and validation

• Instrument control (analog/digital resources)

• Test time optimization and parallelism strategies

• Expanded: Cohu DxV Experience Expectations

• Candidates must demonstrate deep functional and operational knowledge of the Cohu DxV platform, including:

Test Program Development:

• Writing and optimizing DxV test programs using native development environments

• Implementing complex test flows for mixed-signal devices

• Debugging test failures and improving coverage

Mixed-Signal Instrumentation Use:

• Configuring and using analog and digital instrument resources

• Handling precision measurements (ADC/DAC validation, voltage/current accuracy)

• Synchronizing digital pattern generation with analog measurements

Hardware Integration:

• Working with Device Interface Boards (DIBs) and probe/load boards

• Debugging signal integrity and hardware/software interactions

• Production Readiness:

• Optimizing test time and multi-site efficiency

• Supporting yield ramp and production qualification

• Performing correlation between bench, validation systems, and ATE

Debug & Optimization:

• Root cause analysis of test failures (hardware vs software vs design)

• Improving test robustness and repeatability

IC & Domain Expertise:

• Experience with 16-bit to 32-bit IC architectures

• Strong understanding of mixed-signal systems (Analog Digital)

Familiarity with:

• ARM Cortex-M0 or similar embedded processors

• Sensor-integrated ICs (accelerometers, sensing elements)

• Signal acquisition and conditioning circuits

Functional Test Knowledge

Testing and validation of:

• Pacing engines

• Signal sensing circuits

• Accelerometer-based systems
  
  

Additional / Preferred Skills:

• Experience with Credence D10 (legacy ATE systems)

• Ability to work across multiple test platforms and legacy environments

• Background in medical devices or implantable electronics (strong plus)

• Experience with test method migration from legacy to modern ATE systems
  
  

Ideal Candidate Profile:

• 4 years of experience in ATE test development (mixed-signal focus)

• Proven expertise in Cohu DxV platform (must-have)

• Strong problem-solving skills in test/debug/production environments

• Ability to adapt to complex, multi-program semiconductor projects
