Overview We’re reinventing payments. In less than four years, Dojo disrupted the market to become the largest and most loved acquirer in the UK. Our payments infrastructure, purpose-built for in‑person commerce, is game changing. Now, over 150,000 customers across four countries choose to transact billions with us every year. But we’re just getting started. Our people are the driving force behind our success — our greatest investment and ultimate competitive advantage. We hire exceptional people and give them autonomy, trust, and ownership to thrive. The role Our mission is to decouple payments from hardware by building a world‑class software payment engine that allows any partner or Dojo app to accept payments on any device, anywhere. This is the core purpose of our Payment Engine team.

Mentor other engineers, sharing expertise in SDK design, security, and Android best practices.

What you will bring

Deep experience using Coroutines, dependency injection, and modern architectural patterns such as MVVM, Clean Architecture. A strong background in and understanding of payment systems, security principles, or PCI compliance. A product‑focused mindset, thinking from the perspective of developers who are your customers. Excellent problem‑solving skills, navigating deep technical ambiguity in complex domains. A strong sense of ownership and a passion for building secure, reliable, and mission‑critical software.

Dojo home and away We believe our best work happens when we collaborate in‑person. These “together days” foster communication, drive innovation, and spark ideas. Our office‑first culture means working from the office 4+ days per week. With offices across Europe, we offer quiet zones for focus, collaboration spaces for big ideas, and social hubs for quick catch‑ups. Question: what’s curious, relentless, and customer‑obsessed? If you’re keen to know the answer, you’re a third of the way to meeting our Dojo values. If the following speak to you, let’s talk:

You’re curious. You have a real desire to learn and create. You’re relentless. You keep going even when it’s easier not to. You’re customer‑obsessed. You know how important customers are to what you do.
