Thermal / CFD Engineer (Simulation Models)
Title: Freelance CFD Engineer for PCM-Based Cooling System Simulation
Description:
Humboldt Blue is developing a novel cooling system that uses high-pressure Phase Change Materials (PCM) to store and transfer heat.
We’re seeking a thermal or CFD simulation expert to build or refine a simulation model of heat transfer within the system.
Responsibilities:
-
Develop or adapt a CFD / thermal simulation framework (Ansys, COMSOL, OpenFOAM, or similar).
-
Model PCM phase transitions and water/PCM heat exchange.
-
Run sensitivity analyses and help calibrate the model with test data.
Profile:
-
Experience in heat transfer modeling, fluid dynamics, or thermodynamics.
-
Familiarity with PCM materials is highly valued.
-
Analytical mindset and ability to communicate results clearly.
Duration: Freelance or consulting basis.
Location: Remote.
3D Designer / Modeler (Rendering & Animation)
Description:
We’re looking for a talented 3D artist or animator to create a clean, realistic visual model of a modular cooling system developed by Humboldt Blue.
The goal is to visually communicate how the system works — not every technical detail — but its key components, energy flows, and innovative design.
What we’re looking for:
-
Strong skills in Blender, Cinema 4D, or Unreal Engine.
-
Experience creating product or industrial animations.
-
Ability to work from sketches, CAD files, or written descriptions.
-
Understanding of physics-based rendering and fluid motion is a plus.
Outcome: A short animation (30–60 seconds) showing the operation of the cooling system.
Location: Remote
Mechanical Engineer (CAD / HVAC Systems)
Title: Freelance Mechanical Engineer (CAD / HVAC Systems)
Description:
Humboldt Blue is developing a new type of zero-emission chiller based on advanced Phase Change Materials (PCM).
We’re looking for a mechanical engineer with strong CAD experience (SolidWorks, Fusion 360, or similar) to help us create a high-quality 3D model of our prototype system.
You’ll work from existing system architecture and technical descriptions, focusing on mechanical structure, components layout, and fluid circuits (water + PCM).
What we’re looking for:
-
Background in mechanical design for HVAC, refrigeration, or thermal systems.
-
Proficiency in 3D CAD (SolidWorks, Fusion 360, or equivalent).
-
Ability to translate technical schematics into realistic assemblies.
-
Experience with pressure vessels or heat exchangers is a plus.
Duration: Short-term freelance, potential for future collaboration.
Location: Remote.
