At FUZED, we’re on a mission to transform the health and well-being of the next generation by using gaming as a force for good. While others focus on restricting screen time, we see an opportunity to meet young people where they already are — on their screens — and turn gaming into a catalyst for real-world movement.

Now we’re looking for a Full-Stack Engineer with a passion for Machine Learning and Computer Vision to help us build the most accurate, delightful motion analysis engine in youth gaming.

This is not a typical software job. This is a chance to shape a category.

FUZED is a gaming & health startup from Stockholm that engages online gamers through physical activities.

With gaming being the world’s biggest hobby — and the average 10-year-old spending over 7 hours a day on screens outside school — the need for healthier digital ecosystems has never been greater. By combining the right infrastructure, platform, and community, we’re redefining gaming to drive a massive impact on youth health.

We partner with cities to build free-to-access spaces where gaming meets movement. Our platform rewards physical activity with screen-time credits that can be used inside our app, in our arenas, or at home. From football challenges to AI-powered workouts to competitions like FUZED TROPHY™, we’re creating a community where moving more unlocks more play.

A core pillar of this experience is FUZED Arcade — a camera-based challenge system where kids complete movements, tricks, and physical games. To push this to the next level, we need someone who can combine full-stack engineering with machine learning and computer vision to build a motion engine unlike anything on the market.

You’ll own and build technology that interacts with thousands of young players in real time. You’ll turn raw video into meaningful feedback, challenges, rewards, and game mechanics. You’ll work in a fast, senior team where shipping beats bureaucracy, and impact beats perfection.

And most importantly:

Your work directly helps kids become more active, confident, and healthy — through systems they actually want to use.

You’ll be one of the key engineers behind our platform and our ML/CV-based motion engine.

This includes:

• Delivering major full-stack features within your first 3–6 months (e.g., event registration, partner integrations, or arcade systems).
• Designing and building the data collection + training pipeline for our motion analysis engine using Arcade video data.
• Architecting and scaling systems to handle event-time spikes (registrations, live game data).
• Creating reusable APIs and components for the platform, analytics, mobile apps, and Arcade.
• Improving our architecture for speed and iteration.
• Writing clear documentation and onboarding material for future engineers.

You’ll work across backend, frontend, cloud infrastructure, ML models, and edge execution environments.

Few roles offer this kind of variety, ownership, and creative technical challenge.

You’re a builder with range — someone who thrives moving across stacks and learning new systems fast.

You have:

• Experience and/or strong interest in Machine Learning and Computer Vision.
• Strong skills in Node.js, Typescript, Next.js, GraphQL/Hasura, Postgres/SQL.
• Experience with GCP, Golang, and Python.
• Solid understanding of API design, microservices, performance, and scalability.
• Comfort bridging backend, frontend, and mobile contexts.
• Experience with mentorship, code review, or leadership ambition.

And beyond the technical:

• You take ownership.
• You move quickly without breaking the mission.
• You care about real users (kids, families, communities).
• You stay curious, learn constantly, and share generously.
  

Because few engineering roles combine:

• meaningful social impact
• gamification + ML + computer vision
• real-time distributed systems
• a physical + digital product ecosystem
• a small senior team
• massive scale potential

You’ll help define what “active gaming” means for an entire generation.

Apply now and help us create the motion engine that powers the future of movement-based gaming — and helps kids around the world live healthier, happier lives.
