About the role
How do you want to pay? It’s a question you’ve answered on-screen or in-person thousands of times, but your choices have always been limited. Imagine the flexibility to pay however you want – card, QR code, credit, installments, debit, multiple currencies, reward points, or a combination of any of these - all on the same Account. Sound impossible? Episode Six makes the seemingly impossible happen every day.

We provide technology for clients in 24 countries on four continents. Since 2018 when we launched with HSBC, we have grown more than 10x.
