Job Description

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

You own the code that lives on the device itself. A wearable that reads signals from the body around the clock, on a tiny battery, and never loses a night of data. Everything the company does sits on top of your work being right.

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 * Firmware: sensor drivers, data pipeline on the device, power management, FOTA, etc

  • BLE that syncs reliably in the real world
  • Getting every hour of battery life out of the hardware without dropping a sample

You'll fit if you: * Run at a high level of agency. You see what needs doing and do it, no hand-holding.

  • Ship. Devices in the field, side projects with a soldering iron, open source drivers. These count more than a basic CV.
  • Have shipped embedded code on constrained, battery-powered hardware and lived with the consequences.
  • Stay with things. We back people who commit to a mission, not job-hoppers.

Bonuses: taken a consumer device through manufacturing and the field failures that follow, time at a wearable (Oura, WHOOP) or in health, wellness or IoT, a biohacker, obsessive about something niche, scrappy by default.

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.

We are incredibly selective with who we want to join us - if you think you're as mission-driven and people-driven as us, show us why you deserve a seat at Suna.
