Founding iOS Engineer (m/f/d)

Most labs still count cells under a microscope by hand. It's slow, repetitive, and error-prone. We're replacing that manual work with software.

By combining a standard microscope with a smartphone, we run computer vision models that locate, track, and measure cells automatically in real time. We're starting with semen analysis and expanding to other routine microscopic samples. We're a small, well-funded team in Berlin, founded in 2026.

Our goal is to make automated, reliable diagnostic analysis accessible on any phone connected to a microscope.

We're looking for an iOS engineer who loves the camera. Our app turns an iPhone on a microscope into a lab instrument, and the hard problems live on the device: holding focus on a moving sample, running computer vision in real time, and capturing a recording precise enough for a clinical result. On top of that, the app has to be simple enough for a technician in a busy lab.

You'll own it end to end, together with the founders.

Own the app end to end, from architecture to release.

Push the iPhone camera and on-device models to their limits, so every recording is good enough to analyse.

Design the capture workflow with lab staff, so technicians get it right the first time.

Spend time in the lab, measure what works, and decide what to build next.

Camera depth. You've built on the iOS camera stack, not just used it: AVFoundation with manual focus, exposure and white balance, and real-tim
