Within 6 months you'll:

  • Help introduce significant new features which radically improve our product.
  • Impact the quality of the product, getting to the point where we fix all bugs and are improving performance metrics
  • Be proud of the product and the codebase

Your qualifications 👨‍🎓

  • Knowledge of security and/or devops best practices
  • Experience within the Payments domain
