Scientist
/ Engineer
Coolit transforms medical devices into beautiful lifestyle objects. First, we're building Coolit One — a discreet, beautifully designed case that keeps medication cool. We need someone who thinks rigorously about thermal physics and creatively about engineering cooling systems. This role spans materials selection, bench testing, simulation, and design-for-manufacture — from first principles to finished product.
Perfected
Millions of people carry temperature-sensitive medicines in pockets, bags, and everyday life, where ambient heat degrades them silently and dangerously.
You'll own the thermal architecture of our core product: designing, testing, and iterating cooling systems that protect medication without electronics or compromise on the user experience and form of the final product.
Actually Do
- Conduct desk research to identify suitable candidate cooling approaches, methods, and materials
- Respond to the design brief and ensure that the technical requirements for Coolit One meet goals for the user experience
- Design and lead bench experimentation programmes, from hypothesis through to data
- Run DoE (Design of Experiments) cycles to optimise thermal performance
- Build and validate in-silico thermal models to accelerate iteration and reduce prototyping cost
- Select, source, and procure thermal materials and insulative substrates from suppliers
- Develop, test, and iterate on thermal materials to meet performance and product requirements
- Feed into design-for-manufacture decisions as the product moves toward production
Background
- Postgraduate degree (MSc or PhD) in Thermal or Mechanical Engineering, Materials Science, Physics, or a closely related field
- Hands-on lab experience: you've run experiments, not just supervised them
- Fluency with thermal simulation tools (FEA / CFD) — and the judgement to know their limits
- Experience with passive thermal management: advanced thermal materials, heat spreaders, insulation, surface coatings
- An open mind and a drive to push beyond conventional solutions — we're looking for someone who thinks creatively and isn't satisfied until the answer is genuinely novel
- Comfortable working across disciplines — our team spans materials, industrial design, and clinical science. Interdisciplinarity is encouraged.
Experience
- Design for manufacture (DFM) experience in a production or near-production context
- Familiarity with medical device or regulated product development environments
- Experience with surface coatings relevant to thermal or barrier performance
- Project management of lab-based development programmes
- Any prior work bridging thermal science with consumer or lifestyle products
