Lead iOS Engineer

Company:

SimpleStudy is a consumer AI platform for students.

Our small team has already helped +1.5 M students worldwide (UK, Ireland, Brazil, South Africa, and Australia) study better, and ~40–50k new students join us every week.

We are a remote team with a Lisbon office, having recently raised ~$4M seed round with incredible investors from Strava, OpenAI, and Meta.
