Engineering at FitnessAI

Engineering team and processes

FitnessAI operates on a weekly product cycle. We work in short sprints to push features as quickly as possible, aiming to ship updates every Friday. This isn't a strict schedule by any means, but it is what we strive for. We believe success is a function of iteration – iterate twice as fast and we'll learn twice as much. We rarely push to testflight, and consider our users our testers. Engineers typically work off sketch files, but are encouraged to alter the UX as they see fit. We use pull requests to conduct code reviews, and use Linear for project tracking.

Technical Challenges

We're building a set of algorithms that outperform human trainers. Workout data is incredibly structured, and lends itself perfectly to data science & machine learning. Join us in changing the way people build muscle and lose fat.

Projects you might work on
  • You'd work on building a a stats page in our iOS app that lets users track their progress for each exercise over time.

  • You'd work on building a way for people to create and edit new routines, letting them choose what exercises they want to perform, and leaving reps, sets and weight optimizations up to FitnessAI.

  • You'd work on making FitnessAI more social, by building a way for people to ask questions and share personal records with the community, right from inside FitnessAI.
