Engineering at FitnessAI
Engineering team and processes

Our engineering team is me, the CEO 👋I've written every line of code so far and have a very technical background. I treat cancellation reasons as my backlog for feature requests and try to push to the App Store at least once every 2 weeks. I'm a hacker at heart — while the codebase is clean, it is not meant to be worked on by many people. This needs to change and I need to focus on product, so I'm looking for experienced engineers to take ownership over what our engineering practices will be and implement them to set us up for the future.

Technical Challenges

We're building machine learning fitness algorithms powered by over 6M weight lifting workouts from 40K people. This is larger than any publicly available dataset on the subject.

Projects you might work on
  • AI currently happens on device and changes to the model require an update. We'll need to eventually make this cloud based, so there's a lot of API work to be done.

  • Building out other verticals like Nutrition, Cardio & Meditation from start to finish, including frontend and backend.

  • Automate ad-spend using the Facebook Marketing API

Working at FitnessAI

I'm the only person who's put work into building FitnessAI so far – everything from branding to actual coding. I'm looking for similar Jacks (or Janes) of all trades who are incredibly detail oriented and feel they understand things better than most.

If these traits describe you, lets chat

  • Relentless problem solving
  • Incredible optimism.
  • Quick to make decisions
  • Values failures as much as successes
  • Excited by efficiency

Anything is possible with the right perspective & some hard work.
