Our team is growing fast, and our ambitions are general. We operate at the intersection of

health, gamification, and technology

, and we're building a world-class engineering team to support this growth. If you're passionate about building high-performance backend systems and leading the people who build them, we'd love to meet you! Please send the CV in English.

I’m looking for someone who trusts AI to multiply their output and who will push our team to grow and iterate faster because of it.
