About the job
Overview:
We're developing a premium chilled-water dispenser and have a working bench prototype that cools water using thermoelectric (Peltier) modules mounted to a stainless tank base. The proof of concept is validated — the system demonstrably chills water — and we're now looking for a thermal/mechanical engineer to help us engineer the production cooling system.
The core engineering problem:
The prototype proves the principle but reveals the real challenge: getting enough cold into the water efficiently and quietly. We need an engineer to assess and improve three things:
1. Hot-side heat rejection — the current air-cooled heatsink/fan approach is the likely ceiling on performance. We want a view on liquid-cooling the hot side vs. alternatives.
2. Delivered cooling capacity and efficiency (COP) — quantify what's actually reaching the water and how to materially increase it.
3. The thermal path from cold plate to tank base — reducing interface losses into the dished stainless base.
The duty cycle is "pull down from ambient, then hold" — that sizing question is central, and we're open to the engine choice (larger/liquid-cooled Peltier array vs. a compressor-driven cold plate). We have detailed bench data from controlled tests to share.
Scope of work:
- Review our current design and bench results
- Recommend a production cooling architecture with supporting thermal calculations
- Advise on component selection, hot-side strategy, noise, and design-f...

Scope of work:
- Review our current design and bench results
- Recommend a production cooling architecture with supporting thermal calculations
- Advise on component selection, hot-side strategy, noise, and design-for-manufacture considerations
- (Optional follow-on) specify the next prototype build
Deliverables:
- A short technical assessment of the current system
- A recommended design direction with the reasoning and calculations behind it
- Component/architecture recommendations
Requirements:
Strong background in thermal engineering / heat transfer, ideally with thermoelectric cooling or refrigeration experience, and a track record taking physical products toward manufacture.
A full technical brief with prototype specifications, test data, and photos is available to shortlisted candidates under NDA.
