Open Roles
Who we are: TNS is the lab-grade fitness and nutrition app for people who refuse to leave results to luck. Our self-funded startup pairs 25 years of elite coaching expertise with modern EC2-based cloud infrastructure to wipe out the guesswork in training, nutrition, recovery and more. After months of talking to real users and pressure-testing product-market fit, we’re ready to transform a dialed-in roadmap and validated algorithms into a launch-ready product that will become irreplaceable.
Mission: Eliminate guesswork in fitness and nutrition for the outcome-obsessed.
Vision: Redefine the way ambitious people manage health and performance. We see a future where fragmented tools are obsolete, and everyone serious about their outcomes runs their body like a system, powered by unified, responsive, research-grade infrastructure.

If you landed here looking for a bulleted list of “5+ years of X” and “must love stand-ups at 9,” keep scrolling. TNS isn’t hiring a resume, we’re recruiting a mind on a mission. We’ll hand you a greenfield, a crystal-clear roadmap, and a founder who’s already laid down much of the core science and decision logic. You’ll own complete user flows, front-to-back, and craft your own dream-job description, detailing how you’d spend each day.
