Senior R&D Engineer (Topology Optimisation & CFD)

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 want to see your code manifest as physical hardware deployed at a global scale, you belong here.

The Role

As a Senior R&D Engineer, you are the master of the "algorithmic engine" that powers our thermal breakthroughs.

You won't just be a user of existing software; you will be a software developer responsible for building and refining the proprietary generative design kernel that defines our products.

This is a high-autonomy role where you will translate "impossible" thermal math into the code that generates the next generation of liquid-cooled cold plates.

Key Responsibilities

Architect the Solver

Develop and maintain our proprietary generative design engine, writing custom C++/Python code within OpenFOAM or similar CFD frameworks.

Optimize the "Smartfins" Logic

Implement cutting-edge Topology Optimization methods:

• Adjoint methods
• Level-Set
• SIMP

Push the boundaries of Conjugate Heat Transfer.

Bridge Math and Manufacturing

Integrate real-world manufacturing constraints directly into the optimization loop to ensure designs are "ready-to-ship."

Drive the Digital Twin

Collaborate with our software team to automate design cycles.

Lead through Research

Translate complex thermal research into scalable, high-performance code capable of handling the rapid refresh cycles of advanced CPUs and GPUs.

The Essentials

Advanced Academic Background

A PhD or Master’s degree in:

• Mathematical Engineering
• Mechanical Engineering
• Or a related field

Developer Mindset

Proven ability to write and implement custom solvers/tools in C++ or Python.

You are a creator of tools, not just a consumer of them.

Topology Optimization Expertise

Deep technical knowledge of:

• Adjoint methods
• Density-based (SIMP)
• Level-Set approaches

Thermal Fluency

Strong foundation in:

• Thermodynamics
• Liquid cooling
• Conjugate Heat Transfer (CHT)

Startup Grit

You thrive in lean environments where you own the full design lifecycle and prefer rapid prototyping over corporate red tape.

The "Extra Mile"

• Experience implementing manufacturing constraints into optimization frameworks
  • Example: overhang angles for 3D printing or high-volume casting
• Experience with OpenFOAM or similar open-source CFD frameworks
• Familiarity with the data center or AI infrastructure space
• A portfolio of research or projects where you’ve scaled "stealth" concepts into industry-standard applications

Why Join Us?

Real Ownership:  We are a capital-light, agile team where your algorithmic decisions directly impact the physical product and the company’s trajectory.

Global Impact: You are directly contributing to reducing the massive energy footprint of the AI revolution.

The Pace: We operate at the inflection point of the GPU/CPU refresh cycle — fast, iterative, and always pushing the boundary of what's possible.
