REQ: ATE Test Development Engineer (Cohu DxV) in Sylmar, CA (Onsite)

Hi,

One of our clients is looking for ATE Test Development Engineer (Cohu DxV) in Sylmar, CA (Onsite)

Title: ATE Test Development Engineer (Cohu DxV)

Location: Sylmar, CA (Onsite)

Duration: 3 Months

Can work on C2C or W2 Only

Role Overview

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:
o Test program development and debugging
o Device interface board (DIB) bring-up and validation
o Instrument control (analog/digital resources)
o 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:
o Writing and optimizing DxV test programs using native development environments
o Implementing complex test flows for mixed-signal devices
o Debugging test failures and improving coverage

Mixed-Signal Instrumentation Use:
o Configuring and using analog and digital instrument resources
o Handling precision measurements (ADC/DAC validation, voltage/current accuracy)
o Synchronizing digital pattern generation with analog measurements

Hardware Integration:
o Working with Device Interface Boards (DIBs) and probe/load boards
o Debugging signal integrity and hardware/software interactions

Production Readiness:
o Optimizing test time and multi-site efficiency
o Supporting yield ramp and production qualification
o Performing correlation between bench, validation systems, and ATE

Debug & Optimization:
o Root cause analysis of test failures (hardware vs software vs design)
o 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:
o ARM Cortex-M0 or similar embedded processors
o Sensor-integrated ICs (accelerometers, sensing elements)
o Signal acquisition and conditioning circuits

Functional Test Knowledge

Testing and validation of:
o Pacing engines
o Signal sensing circuits
o 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
