Barcelona, Barcelona, España FitXR A tiempo completo 60.000 € - 90.000 € al año

At FitXR, we're building the future of fitness - immersive workouts which turn movement into play, not punishment. We're for the misfits: the ones who've always felt a little out of place in traditional fitness spaces. This is a new kind of community where movement is inclusive and everyone belongs.

We're looking for a Senior Engineer to bring their React expertise into the 3D world and build interactive experiences that make movement genuinely fun. You'll be joining a small, high-trust and fully remote team who are obsessed with learning fast and helping people move because they want to, not because they should.

What you'll do
  • Lead the tech side of features from brainstorm to release - balancing speed, polish, and player joy
  • Be the go-to React expert - setting best practices, performance tuning and helping us build smarter, not harder
  • Team up with Designers, Product and Unity/Backend Engineers to make VR interfaces feel seamless and alive
  • Help define how we build - bringing product thinking and technical insight to every sprint
  • Share knowledge, raising the overall level of code craft and collaboration
  • Push the limits of our React–Unity integration to unlock even richer player experiences
You should apply if

You're a proactive, product-minded engineer with:

  • Strong React experience in production environments
  • Proven ability to own projects end-to-end, balancing delivery speed with solid engineering principles
  • Experience working in small, cross-functional teams
  • Excellent communication - you keep people in the loop, surface blockers early, and stay cool in chaos
  • Comfort with ambiguity - you can build clarity where none exists
  • Curiosity about 3D, gaming, or VR - bonus if you've built something weird and fun before
  • Perspective of AI as a teammate, not a threat - you're leveraging AI to speed up your workflow, generate tests and help prototype ideas faster

Nice-to-have experience:

  • Some Unity or VR development - professional or hobby
  • Backend development - C# preferred
  • Automated testing pipelines
You shouldn't apply if
  • You want a 200-page spec before you start coding
  • You prefer working in a giant org where decisions move slower than patch notes
  • You're allergic to collaboration or ownership
