Thermal engineer to develop a thermoelectric (Peltier) cooling system for a chilled-water dispenser Ended

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... read more

- 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. read less
