  • Engaging in product and design discussions, contributing ideas for what you will be building.
  • Constantly questioning. Why are you building this? How can it be improved? What can we learn from this?
  • Adapting quickly to changing requirements and environments; you will need to respond to unexpected challenges with a cool head and a positive attitude.

What does that look like?

  • Always willing to get stuck into an unfamiliar problem and looking to learn
  • Can communicate clearly, concisely and kindly with technical and non-technical coworkers
  • Interest and passion for fitness
  • Start date will be the end of June/ beginning of July
  • The role is based at Fiit HQ, London, so our office needs to be accessible to you.

This would also be a bonus

  • Video streaming experience
  • TV app experience
  • Node server development
  • Knowledge of GraphQL
  • Experience developing cloud applications on AWS, using services such as S3, Lambda, API Gateway, SQS, DynamoDB
