Job description

Working at CreateFuture

CreateFuture is an AI-native consulting partner where people do work that matters and are supported to do it well. We work alongside organisations such as PayPal, adidas, NatWest, FanDuel and Money Saving Expert, building digital products and services that make a difference while always putting people first.

We’re a team of creators. We write code, shape delivery, build go-to-market strategies, develop AI solutions and create the practices that support our people. We work side by side with our clients, challenging what’s not working and helping them to build the future. Our commitment to craft, quality, and culture has helped us scale to over 600 people in just a few years.

CreateFuture is a Great Place to Work-Certified™ company and has won Best Workplaces UK multiple years in a row.

Join us on our journey. Let’s create tomorrow, together, today.

About the role and team:

Our Mobile team works simultaneously to bring similar but distinct experiences to our clients. As we continue we’re always looking to find and adopt the best tools for the job - whether that’s making our CI better with automated code scanning and UI testing or developing reusable libraries that we can share across projects.

We conduct unit testing across all our projects, code is always peer reviewed, and we encourage these reviews to happen “over the shoulder” (or on a call more recently) to make it a better environment for team members to learn from each other. As a team we meet regularly to discuss new approaches and challenges, whether that’s within our project teams or in the wider mobile community.

What you’ll be doing:

• Building high-quality mobile apps with Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP), using shared business logic and UI across iOS and other platforms
• Writing clean, maintainable and well-tested code using Kotlin and modern mobile development practices
• Creating intuitive, responsive user interfaces using Compose Multiplatform, faithfully recreating the existing product
• Integrating shared Kotlin Multiplatform modules with native iOS platform APIs (e.g. biometrics, Apple Wallet, keychain, push notifications) and contributing to shared KMP codebases
• Working closely with the wider engineering team and key customer stakeholders, who hold the product knowledge, in a self-led environment
• Championing engineering excellence and best practices across KMP, CMP and iOS development

We’d love to talk to you if you:

• iOS platform knowledge (Xcode, iOS frameworks and tooling) is strongly preferred; Swift familiarity is a plus
• Hands‑on commercial Kotlin Multiplatform (KMP) experience and an understanding of how to architect and integrate shared codebases across platforms
• Hands‑on experience with Compose Multiplatform or Jetpack Compose, and modern mobile application architecture
• Comfortable working with Kotlin and integrating shared KMP modules with native iOS APIs
• Hands‑on experience using AI coding tools (e.g. Claude Code) as part of day‑to‑day delivery
• Strong focus on code quality, testing and clean architecture principles
• Experience working effectively in a self‑led environment without dedicated product, design or QA support
• Desirable: experience releasing iOS apps to the App Store from a KMP + CMP codebase
• Desirable: Android / Jetpack Compose experience

What we’ll offer you:

We trust people to do their best work. That means flexibility over rigid rules, impact over activity, and real investment in your growth both professionally and personally. You’ll be part of a supportive, and friendly culture, surrounded by smart, curious people who care deeply about what they do.

We offer flexible working, including hybrid and remote options. Our office hubs are located in Edinburgh, Leeds, Manchester, London and Bulgaria, with occasional travel to client sites or CreateFuture offices when needed.

We trust you to manage your time balancing collaboration with client time and focused work. What matters is the impact you have, not how busy you look.

Our hiring process

We try to keep our hiring process clear, fair and respectful of your time. We aim to get back to everyone who applies and we will be upfront about where you are in the process.

It usually looks like this:

• Call with our Talent Acquisition Team
• Role specific capability interview

Depending on the role, we might also ask you to do a short presentation, a practical or technical task or have a values focused conversation. We will explain what is involved before anything happens.

Inclusion at CreateFuture

We believe diverse teams build better workplaces and better products. We want CreateFuture to be a place where people feel able to be themselves and do their best work.

If you need any adjustments or support during the application process, just. We will do what we can to help.

We look forward to your application!
