Founding Mechanical Engineer

Company: Suna Health
Apply for the Founding Mechanical Engineer
Location: London
Job Description:

The First Wearable for your Gut & Nutrition (www.suna.health)

You own the physical object: mechanical design, industrial design and the tooling that turns both into something people wear around the clock. A device worn on skin has to earn its place there, and that is your job.

Quick facts: London, in person · Full-time · Competitive salary + equity · Small founding team

What this actually is

Nobody has properly cracked real-time signals from this part of the body. We are building the first wearable for gut and nutrition, on a mission to make the human body understandable to anyone. This is a real seat on the founding team. You own your patch end to end, and what you own grows as fast as you can carry it.

What you’ll own

  • Mechanical construction: DFM, DFA, materials and tolerance stacks
  • Industrial design: form factor, comfort, look and feel
  • Tooling and production: injection moulding, toolmakers, manufacturing partners. You commission tools, you do not just draw them
  • The skin interface: adhesives, materials and comfort across days of continuous wear
  • The mechanical structures our sensing depends on: cavities, seals and membranes

You’ll fit if you

  • Run at a high level of agency. You see what needs doing and do it, no hand-holding.
  • Ship. You have shipped a physical consumer product and watched real people drop it, sweat on it and wear it.
  • Know what a mould tool costs, takes and forgives. Tooling is familiar ground for you
  • Are equally fluent in CAD, on a factory floor, and in an argument about a 0.2mm wall thickness.
  • Stay with things. We back people who commit to a mission, not job-hoppers.

Bonuses: wearables or other skin-worn devices, injection moulding from tool design to first article, a portfolio of shipped objects (not just renders), consultancy years behind you and product years ahead of you, time at a wearable (Oura, WHOOP) or in health, wellness or IoT.

Dealbreakers

Be honest with yourself before you apply. This is not the one if:

  • No prior interest in health or health tech.
  • You are high maintenance.
  • You hop jobs. It is a red flag for us.
  • You chase big names and vanity metrics over the mission.
  • You want a strict 9-to-5. This will never be that.
