Informacje o stanowisku

Let’s get straight to the point — we’re building the next chapter in interactive fitness. We’re a team of tech-driven fitness enthusiasts who believe that working out should be something people actually enjoy. So we started designing. From the ground up.

The result? A one-of-a-kind device — a smart IoT-powered strength training machine that combines advanced hardware with an AI-powered personal coach. It’s built for effective, personalized strength workouts at home, with real-time feedback, tracking, and progress you can feel.

This project is being developed for an Israeli startup in the fitness space, aiming to redefine how people train at home through a truly innovative product.

Our team brings together experienced designers, product managers, and top-tier software and hardware engineers — many of whom have worked on some of the most recognized consumer tech products out there. Now, we’re combining our skills to build something that will reshape home fitness — engaging, effective, and genuinely rewarding.

We can’t wait to show you what we’ve been working on.
