Probe Process Engineer

WD is building the infrastructure behind the AI-driven data economy.

As AI scales, so does data. Every interaction, every model, every system generates data that must be stored, managed, and made accessible over time. That’s where we come in.

We combine deep engineering expertise with global-scale manufacturing to deliver the storage systems that make AI possible, powering hyperscale data centers, cloud platforms, and enterprise infrastructure worldwide.

This isn’t theoretical work. It’s real systems, at real scale, people solving some of the hardest challenges in technology today.

We’re looking for people who want to build, solve, and operate at that level.

Join us and let’s shape the future of data.

The Process Engineer will support wafer probe operations for both product development and high-volume manufacturing environments. This role is responsible for developing, sustaining, and optimizing wafer probe processes, test methodologies, SPC systems, probe card configurations, and test setup infrastructure. The engineer will work closely with Test Engineering, Product Development, Yield Engineering, Manufacturing, and Operations teams to ensure robust process control, measurement integrity, and successful new product introductions.

Responsibilities

Develop, qualify, and sustain wafer probe processes for new and existing products, including probe recipes, operating specifications, setup requirements, and engineering controls across both product development and high-volume manufacturing environments.; Define, validate, and maintain probe card configurations and wafer test setups, supporting qualifications, releases, maintenance strategies, and change management to ensure test readiness for engineering builds, qualifications, and production ramps.; Monitor and optimize process performance using SPC, EDC, and statistical analysis, develop and maintain control limits, OCAPs, screening methodologies, and engineering dashboards to ensure measurement integrity and data accuracy.; Investigate process excursions and implement data-driven corrective actions through characterization studies, gauge capability evaluations, and tool correlation analyses to improve yield, quality, and cycle time.; Lead wafer probe readiness for New Product Introductions (NPI), defining product-specific test plans, specifications, and qualification strategies while coordinating cross-functional activities to ensure seamless transfer from development to high-volume manufacturing.; Drive continuous improvement initiatives targeting yield enhancement, cycle time reduction, productivity gains, process simplification, measurement system improvements, and equipment utilization optimization.; Partner with Test Engineering, Product Engineering, Yield Engineering, Manufacturing, Operations, Quality, and IT teams to provide technical leadership in root cause analysis, corrective action implementation, engineering reviews, and documentation of best practices and knowledge transfer materials.

Requirements

BS/MS in Electrical Engineering, Materials Science, Chemical Engineering, Physics, Mechanical Engineering, or related discipline.; Experience in semiconductor manufacturing, wafer probe engineering, or test engineering.; Demonstrated proficiency in electrical measurement techniques with hands-on experience in laboratory and cleanroom environments.; Strong understanding of statistical process control (SPC), design of experiments (DOE), and semiconductor test methodologies.; Proficiency with data analysis tools such as SQL, Python, JMP, Minitab, or equivalent platforms.; Demonstrated knowledge of measurement system analysis (MSA), gauge R&R, and process capability studies.; Proven experience with yield optimization, maintenance protocols, and failure analysis.; Track record of driving process improvements through automation, machine learning, or AI-based initiatives.; Exceptional troubleshooting and root-cause analysis capabilities.; Strong communication and cross-functional collaboration skills with manufacturing, design, and quality teams.

Benefits

An employee’s pay position within the salary range may be based on several factors including but not limited to (1) relevant education, qualifications, certifications, and experience, (2) skills, ability, knowledge of the job, (3) performance, contribution and results, (4) geographic location, (5) shift, (6) internal and external equity, and (7) business and organizational needs.; The salary range is what we believe to be the range of possible compensation for this role at the time of this posting. We may ultimately pay more or less than the posted range and this range is only applicable for jobs to be performed in California, Colorado, New York or remote jobs that can be performed in California, Colorado and New York. This range may be modified in the future.; If your position is non-exempt, you are eligible for overtime pay pursuant to company policy and applicable laws. You may also be eligible for shift differential pay, depending on the shift to which you are assigned.; You will be eligible to be considered for bonuses under either WD’s Short Term Incentive Plan (“STI Plan”) or the Sales Incentive Plan (“SIP”) which provides incentive awards based on Company and individual performance, depending on your role and your performance. You may be eligible to participate in our annual Long-Term Incentive (LTI) program, which consists of restricted stock units (RSUs) or cash equivalents, pursuant to the terms of the LTI plan. Please note that not all roles are eligible to participate in the LTI program, and not all roles are eligible for equity under the LTI plan. RSU awards are also available to eligible new hires, subject to WD's Standard Terms and Conditions for Restricted Stock Unit Awards.; We offer a comprehensive package of benefits including paid vacation time, paid sick leave, medical/dental/vision insurance, life, accident and disability insurance, tax-advantaged flexible spending and health savings accounts, employee assistance program, other voluntary benefit programs such as supplemental life and AD&D, legal plan, pet insurance, critical illness, accident and hospital indemnity, tuition reimbursement, transit, the Applause Program, employee stock purchase plan, and the WD Savings 401(k) Plan.; Note: No amount of pay is considered to be wages or compensation until such amount is earned, vested, and determinable. The amount and availability of any bonus, commission, benefits, or any other form of compensation and benefits that are allocable to a particular employee remains in the Company's sole discretion unless and until paid and may be modified at the Company’s sole discretion, consistent with the law.
