Senior iOS Engineer

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. They are our greatest investment and our ultimate competitive advantage. We hire exceptional people and give them the autonomy, trust, and ownership to thrive. The results take care of themselves. The role As a Senior iOS Engineer at Dojo, you’ll join a centralised platform team dedicated to amplifying our engineering efforts across the entire iOS ecosystem. This isn’t about building single-user features; it’s about empowering developers by creating the robust SDKs, frameworks, and toolkits they rely on. You will drive our architecture and scalability, optimising our CI/CD pipelines and ensuring our applications are performant, modular, and secure as we scale internationally. What you will do... • Design, build, and maintain the centralised iOS SDKs, libraries, and core toolkits that form the foundation of our mobile infrastructure. • Own the modular architecture of our iOS ecosystem, promoting reusability and strong separation of concerns across multiple application teams. • Enhance the developer experience by optimising build times, managing dependencies using Swift Package Manager, and refining our automated testing strategies. • Architect and evolve scalable CI/CD pipelines for mobile automation, ensuring rapid, reliable, and secure release workflows. • Establish and uphold technical standards and best practices for iOS development through clear documentation and rigorous code reviews. • Collaborate with feature teams to understand their pain points and ensure the seamless integration of our core SDKs. What you will bring... • Deep expertise in modern iOS development using Swift and a solid understanding of its core principles. • A proven track record of designing, shipping, and maintaining distributed frameworks or centralised SDKs used across multiple teams. • Strong command of iOS architecture patterns (e.g., MVVM-C, Clean Architecture) optimised for modularity and scalability. • Extensive experience with dependency management (Swift Package Manager) and mobile automation tooling (e.g., GitHub Actions, Bitrise). • A passion for improving developer experience, with a focus on automation, code quality, and building tools that make other engineers more efficient. • Excellent communication skills, with the ability to articulate complex technical concepts and influence technical direction across teams. Dojo home and away We believe our best work happens when we collaborate in-person. These “together days” foster communication, drive innovation and spark our brightest ideas. That's why we have an office-first culture. This means working from the office 4+ days per week. With offices across Europe, we know a thing or two about staying dynamic. Need deep focus? Head to a quiet zone. Big ideas? Collaboration spaces have you covered. Just here for a catch-up? Our social hubs make it easy. Do work that counts, in spaces made for you. 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. Diversity, equity, and inclusion at Dojo From local bakeries to well-known eateries, Dojo payments serve over 150,000 places across the UK.
