Founding Mechanical Engineer

The First Wearable for your Gut & Nutrition ((Use the "Apply for this Job" box below).)

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

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.

• 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

• 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.

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.
