The Role
About Apron

Apron was started by a group of people who’d spent years building products for global fintech companies. But there was one big problem no one was solving. Business payments. The kind that buy tomatoes, tools, and till rolls. The kind that keep suppliers happy and business booming. The kind that should be super simple to make and manage, and yet, aren’t. Payments eat up valuable hours every week for both businesses and the accountants and bookkeepers who help them.

This is a problem that’s affecting entrepreneurs. Florists and financial analysts. Brewers and brand strategists. The kind of people who build things, break things, change things. Imagine what they could do with this time instead. What would they come up with? What would they create?

That’s why we built Apron as a payments powerhouse. We flip the payment experience from blocking business to boosting it. Apron pulls all things payments together – weaving into your workflow, collating conversations, turning hours into minutes. So you can put those hours to better use – plan the future, take a walk, call your mum.

We are backed by Index Ventures, Bessemer Venture Partners, with participation of Visionaries Club and the founders of Melio and Klarna.

Who We’re Looking For

We are seeking highly skilled and experienced mobile developers to join our team. Whether they specialise in iOS, Android, or both, we are particularly interested in developers with a multiplatform mindset who are passionate about creating seamless, high-quality applications for both platforms.

Our goal is to hire developers who understand the importance of cross-platform code sharing and are eager to work with Kotlin Multiplatform (KMP) technology to streamline development across Android and iOS platforms.

At Apron, we recognise that not all developers may have extensive experience with KMP. While this is a plus, what matters most is the genuine interest and excitement to learn and apply KMP in your day-to-day work. 

What You’ll Be Doing
  • Develop and maintain Android and iOS apps, utilising Kotlin Multiplatform (KMP) for cross-platform code sharing.

  • Write clean, scalable, and maintainable code that aligns with industry best practices.

  • Work with design and product teams to deliver features that provide a seamless user experience.

  • Collaborate with product managers, designers, and engineers to define, design, and launch new features.

  • Participate in code reviews to maintain high-quality code and share knowledge across the team.

  • Optimise apps for speed and scalability, and troubleshoot performance issues across platforms.

  • Use profiling tools to diagnose and improve app performance.

  • Support and maintain CI/CD pipelines for Android and iOS apps, streamlining the deployment process.

What You’ll Need
  • 3+ years of professional experience in mobile development (iOS)

  • Familiarity with Jetpack Compose or SwiftUI

  • A solid understanding of mobile app architectures

  • A strong interest in cross-platform development or a willingness to work with Kotlin Multiplatform (KMP)

  • Proficiency in at least one of the following: Swift (iOS) or Kotlin (Android)

  • Comfort working in a fast-paced, product-focused environment

  • Clear and proactive communication skills; thrives in cross-functional teams

Would be a plus if you have
  • Hands-on experience with Kotlin Multiplatform (KMP) in a production setting

  • Experience working in a CI/CD environment (e.g. GitHub Actions)

  • Knowledge of testing frameworks

  • Previous experience in a startup or fintech environment


Benefits
  • Competitive salary and stock options

  • Fully expensed tech

  • Health insurance via AXA

  • Pension plan with Nest

  • Flexible holidays and work-from-home options

  • Deliveroo allowance

  • Life Assurance
