Opportunity Overview

We are seeking a Senior / Principal Mechanical Engineer to provide technical leadership within the System Level Test (SLT) Thermal Engineering group. This role focuses on the design and delivery of advanced thermal solutions that enable testing of high‑power semiconductor devices under challenging operating conditions.

The SLT Thermal group develops end‑to‑end thermal systems, including device‑level cooling hardware, liquid cooling architectures, and active thermal control methods. These solutions support testing of CPUs, GPUs, AI accelerators, automotive ICs, and advanced multi‑die packages at very high-power levels and power densities, where traditional thermal approaches are not sufficient.

This position is suited for an engineer who combines strong fundamentals, hands‑on experimental work, and system‑level thinking, and who is comfortable owning technical direction from concept through production. You will be expected to be the subject-matter expert and thermal management architect of entire system platforms.

What You’ll Work On

In this role, you will lead the definition, design, and validation of thermal systems that directly enable system‑level semiconductor test. The work spans device interfaces through full system integration and requires close collaboration with mechanical, electrical, controls, software, and systems engineering teams.

Technical Field:

+ Architecting and developing device‑level thermal solutions, including liquid‑cooled cold plates, advanced thermal interface materials, and mechanically compliant interfaces designed for repeated test contact and high reliability

+ Designing and analyzing liquid cooling systems that support very high-power density devices, including multi‑branch and manifolded coolant distribution architectures

+ Leading thermal simulation efforts using CFD and analytical methods to assess steady‑state and transient thermal behavior under non‑uniform heat flux and fast power changes

+ Developing thermal solutions that support elevated‑temperature operation and rapid thermal transients, where tight junction‑temperature control is critical for test accuracy and device safety

+ Defining and executing experimental validation plans, including lab instrumentation, data acquisition, and detailed correlation of experimental results to simulation models

+ Collaborating with controls and software engineers to support active thermal control concepts

+ Supporting the transition of thermal designs from prototype through qualification and high‑volume manufacturing, including supplier engagement and technical issue resolution

+ Mentoring junior engineers, reviewing technical work, and contributing to thermal design best practices and standards within the organization

Management and Research Field:

+ Working directly with semiconductor manufacturers and system companies to understand device‑level thermal requirements, test conditions, power profiles, packaging constraints, and roadmap needs

+ Translating customer requirements into clear, actionable product and architecture definitions, balancing performance, risk, cost, and schedule

+ Engaging with customers through onsite visits, technical reviews, and joint debug sessions

+ Acting as a technical point of contact and subject‑matter expert for thermal topics during customer engagements, design reviews, and escalation scenarios

+ Managing customer expectations, timelines, and feature requests, including clear communication of tradeoffs, risks, and development maturity

+ Supporting definition and execution of customer‑driven development programs, from early feasibility through deployment into production environments

The role is also expected to maintain strong technical currency and external awareness, including:

+ Staying current with scientific and industrial advancements in semiconductor thermal management, advanced packaging, liquid cooling, materials, and thermal control methods

+ Monitoring emerging technologies and approaches across academia, suppliers, and adjacent industries

+ Evaluating new concepts and determining when and how they can be transitioned from research or prototype into robust, manufacturable product solutions

+ Comfortably productizing emerging or immature technologies under aggressive schedules, making disciplined engineering decisions to balance innovation with reliability and delivery commitments

Focused Responsibilities

Technical Leadership

+ Own and drive thermal architecture for complex SLT subsystems and systems

+ Lead design trade studies considering performance, reliability, manufacturability, and cost

+ Serve as a technical resource and mentor for other engineers in the group

Thermal Design & Analysis

+ Perform and guide thermal modeling using CFD and analytical methods

+ Design and optimize liquid‑cooled cold plates, thermal interfaces, and supporting structures

+ Evaluate thermal performance of advanced device packages with non‑uniform and transient heat loads

Experimental Validation

+ Plan and execute thermal experiments to validate designs

+ Use experimental data to refine models and inform design decisions

Productization & Manufacturing Support

+ Support transition from prototype to manufacturing

+ Work with suppliers and manufacturing partners on advanced thermal hardware

+ Investigate and resolve thermal issues encountered during qualification or production

Required Qualifications

Education & Experience

+ B.S. in Mechanical Engineering.

+ Typically, 8+ years of experience in thermal, heat‑transfer, or mechanical systems engineering

+ Ability to demonstrate academic knowledge of heat transfer principles

Technical Skills

+ Strong foundation in heat transfer, fluid mechanics, and thermal system design

+ Experience with liquid cooling systems and high‑power electronics

+ Proficiency with thermal simulation tools (CFD / FEA)

+ Experience working with lab data, test instrumentation, and model correlation

Tools & Methods

+ CAD experience (SolidWorks or equivalent)

+ Thermal simulation tools such as ANSYS Fluent, Icepak, COMSOL, OpenFOAM or similar

+ Data analysis using tools such as MATLAB SIMULINK, Python, or LabVIEW
