Careers at Lyfta
Strength training is one of the highest-leverage things a person can do for their body and mind. Our mission is to make it work for everyone: grounded in science, free of hype, and built to last. If that is a mission worth years of your life, keep reading.
Our product is led by an exercise physiologist with a PhD. Every feature is grounded in training research, not fitness trends.
We stay deliberately lean. You will own meaningful surfaces end-to-end, work directly with the founders, and see your work reach users within days.
Lifters train for years and expect tools that hold up. We sweat performance, typography, and edge cases so they never have to think about the app.
Most of our users open the app mid-set, with chalked hands and ninety seconds of rest. We design and test for that reality first, and everything else follows.
All roles are remote-friendly within a few hours of Central European Time. We hire for depth of craft over years of experience.

Shape how millions of lifters plan, log, and review their training. You will work across mobile and web, partner directly with engineering, and ship designs that respect both the science of training and the reality of a phone in a chalky hand.
Own the top of the funnel across paid, organic, content, and lifecycle. You will set the growth strategy, run experiments, and build the measurement stack to compound acquisition over years, not quarters.
