AI Engineer

Website Retmarker

Founded 12 years ago as a spin off from Critical Software, the Retmarker company brings the innovative spirit from its founders to push for the adoption of Artificial Intelligence to the field of Ophthalmology. We are one of the oldest and most respected AI providers in this field. We operate from Coimbra (Portugal) to the World.

The company is currently focused on retinal diseases, namely on Diabetic Retinopathy, where we provide our own computer vision technology and professional services in the implementation of efficient and effective population-based screening programs. Our technology is certified as a medical device.

In recent years, we have been involved in the automated analysis of images from half a million diabetics, contributing to a better management of their disease and preventing blindness.

The company has ambitious plans to grow over the coming years, integrated in a new European group. We intend to speed up our efforts and expand the usage of Deep Learning technology in our products and address new pathologies from retinal images.

In this context, we will be reinforcing our R&D capacity with new elements. One of the elements we are looking for is an AI Engineer to join the AI team.

We are a small team, extremely flexible, that keeps improving our own culture daily. If you like the environment of a startup, but one with a track-record already (real challenges, real data), creating a positive impact on people’s lives, this may be THE opportunity. Remote working in the mid-term is a possibility.
