Client's job description:


We are looking to augment our existing payments teams with additional capacity to accelerate development on global expansion initiatives.


We are currently able to expand to a single market at a time and would like to get to a point where we can be working on multiple market expansion initiatives in parallel. Launching in a new market involves coordinating roadmaps across 5 – 10 teams. When you are working with so many different roadmaps, it’s inevitable that there will be some reprioritization that leads to misalignment and delays. This group of engineers will help to balance out those misalignments by providing reserved global expansion capacity to our internal teams. 


  • RoR experience, 5+ years
  • Problem-solving, algorithms (will be verified by hackerrank and during an interview)
  • Team player
  • English language skills, B2 or higher


Must be available to work 12:00 pm-8:00 pm for the first 2-3 months at least 3 days a week


  • Experience in microservices
  • Experience with AWS
  • Practical Java knowledge


  • Updating processor integrations and adding new features  
  • Building out new money movement flows to align with the merchant and regulatory requirements for new regions  
  • Building new chargeback/disputes flows, working closely with the Treasury team, to align with the merchant and regulatory requirements for new regions 
  • Adding and/or updating fraud prevention tools to align with the merchant and regulatory requirements for new regions 
  • Building merchant reports that meet market-specific expectations  
  • Integrating the system with market-specific wallets and local payment methods
