R&D Engineer (Test and Validation Engineer)

At MegaCool Technologies, we aren't just making parts; we are solving the most physical bottleneck in the AI revolution: Heat .

While traditional data center cooling is reaching its physical limits, we’ve developed ultra-performant Smartfins technology using proprietary generative algorithms.

We are a lean, fast-moving startup bridging the gap between high-level software intelligence and massive-scale hardware manufacturing.

If you believe that a design isn't real until it has been stressed, measured, and validated in the lab, you belong here.

The Role

As our Validation & Experimental Engineer, you are the "Truth Seeker."

You are responsible for designing and building the high-stakes environments that prove our technology's performance.

You won't just be following a test plan; you will be the architect of our experimental ecosystem, building:

• High-pressure liquid loops
• Complex multi-zone Thermal Test Vehicles (TTVs)

This is a high-autonomy role where you own the data flywheel that validates our generative designs.

Key Responsibilities

Architect the Validation Ecosystem

Design, procure, and build state-of-the-art high-pressure liquid loops and complex multi-zone TTVs to simulate the extreme environments of next-gen GPUs.

Automate the Data Flywheel

Develop and maintain autonomous data acquisition workflows using:

• NI DAQ hardware
• Python
• LabVIEW

Ensure high-frequency sensor data is processed at the speed of our hardware refresh cycles.

Master of Metrology

Lead non-intrusive flow measurement and Infrared (IR) thermography initiatives to capture the "invisible" physics of our Smartfins in action.

Close the Loop

Work closely with our CFD and R&D teams to correlate experimental data with numerical models, ensuring our "Digital Twin" is grounded in physical reality.

The Essentials

Advanced Academic Foundation

An MSc or PhD in:

• Experimental Physics
• Thermal Engineering
• Fluid Dynamics
• Or a related field

Hands-on DNA

You are as comfortable with a wrench and a soldering iron as you are with a keyboard.

You have a proven track record of building physical test rigs from scratch.

Data Science Proficiency

Expert-level knowledge of:

• NI DAQ hardware
• LabVIEW
• Python (pandas, SciPy)

Strong ability to build autonomous data processing workflows.

Metrology Expertise

Deep experience with:

• IR thermography
• Advanced fluid measurement techniques

The "Extra Mile"

• Experience in semiconductor, aerospace, or data center cooling sectors
• Familiarity with high-pressure fluid system safety and design standards
• Experience scaling a "stealth" lab environment into a world-class validation facility

Why Join Us?

Full Ownership:  You aren't just running tests; you are building the lab and defining the validation strategy for a category-defining technology.

No Red Tape:  We move at the speed of the hardware we cool. If you need a specific sensor or a new rig to prove a concept, we make it happen.

Global Impact:  Your data is the final proof required to deploy our energy-saving technology at a global scale.
