R&D Engineer (Software Architecture & Automation)

Rotselaar, Belgium

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 our R&D Software Engineer, you are the architect of our internal "Digital Nervous System."

You won't just "automate tasks" - you will design a "self-driving" workflow where code, simulation, and hardware design move in a seamless, automated loop.

This is a high-impact role for a builder who can combine clean software architecture with scientific computing to scale our thermal breakthroughs.

Key Responsibilities

  • Automate engineering and project workflows using AI/LLM-driven solutions
  • Develop scalable, production-ready tools in Python and C++
  • Maintain clean architecture and high coding standards
  • Review code and ensure performance, readability, and reliability
  • Build and maintain CI/CD pipelines for HPC environments
  • Collaborate with teams across physics, CFD, and manufacturing
  • Turn Smartfins prototypes into high-performance software solutions

What You Bring

Essentials

  • MSc in Computer Science, Software Engineering, or related field
  • 2+ years of experience
  • Strong Python skills and good C++ knowledge
  • Experience with clean code, design patterns, and software architecture
  • Experience with CI/CD and HPC environments
  • Interest or background in:
    • CFD
    • Heat transfer
    • CAD automation
    • Engineering simulations

Bonus Skills

  • Slurm or HPC containerization
  • CAD automation (Autodesk API, Open CASCADE)
  • Generative AI / LLM applications
  • CFD solvers such as OpenFOAM or Ansys

Why Join Us?

  • Build systems from scratch with high ownership
  • No red tape — fast execution and real impact
  • Work on technology reducing AI’s energy footprint
  • Join a lean team combining Clean Code with Deep Physics
