Founding ML Engineer

Overview

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

You turn raw signals from the body into things people can read and act on. This is the hard, unsolved centre of the company. The sensors give us continuous data nobody has had before, and your job is to find the patterns in it and make them legible to a normal person.

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.

• The full modelling pipeline: messy real‑world sensor data in, readable insight out
• Signal processing work on continuous physiological data
• Models that run efficiently on‑device and on the backend, and the judgement of what goes where
• How we validate that what we tell people is actually true. Rigour is the product

• Run at a high level of agency. You see what needs doing and do it, no hand‑holding.
• Ship. Models in production, papers with code, Kaggle, a startup. These count more than a basic CV.
• Are as strong at the unglamorous parts (labelling, cleaning, validation) as at the modelling.
• Can hold yourself to scientific honesty when the easy path is an impressive‑looking demo.
• Stay with things. We back people who commit to a mission, not job‑hoppers.

Wearable or physiological sensor data experience, a health, physiology or biosignals background alongside the engineering, obsessive about something niche, scrappy by default.

• 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.
