The Team

The Customer Experience (CX) Team is the face of Capital on Tap’s product offering. We’re a fun and enthusiastic team focused on building elegant and accessible mobile and web platforms for our customers.

Our mission is to make the lives of small business owners easier - whether that’s by rewarding them with Avios and cashback on their spending, simplifying the payment of business bills, or ensuring their expenses seamlessly sync with their accounting software. We’re all about creating a rewarding and enjoyable experience for everyone who uses our services.

What You’ll Be Doing

As a Senior Mobile Engineer in the Customer Delight (CD) team, you’ll play a pivotal role in shaping a complex, multi-faceted product, delivering complex features for both iOS and Android using technologies such as Flutter, GCP and Azure, as well as native mobile technologies such as Kotlin and Swift.

Finally, you'll mentor and share your expertise with your team, nurturing a best-in-class culture of front-end engineering within the team.

We're seeking an engineer who is not just technically proficient but also a collaborative leader. If you're passionate about the customer experience, and thrive in a fast paced environment where you can truly make an impact, we'd love to hear from you!

• You’ll build robust and scalable solutions using predominantly Flutter technologies
• From the first line of code to production, monitoring, and continuous improvement - you’ll own the SDLC
• You’ll analyse and identify bottlenecks and efficiency gains your team can make, and utilise technologies such as AI to create solutions to them.
• Teamwork makes the dream work - you’ll partner with Product Managers, QA’s, and fellow Software Engineers
• You’ll build bulletproof unit and integration tests to keep our software sharp and our users happy
• Bugs happen. When they do, you’ll be ready to troubleshoot and tweak as needed
• You’ll bridge the gap between tech speak and business goals, ensuring everyone’s on the same page and moving forward together
• 3+ years hands-on experience in Flutter and Dart, with a strong understanding of the mobile development ecosystem.
• Experience with building and deploying Android and iOS applications, preferably with knowledge of CodeMagic or similar CI/CD platforms.
• Experience with native mobile development in either Kotlin or Swift (ideally both).
• Good testing practices, in both Unit and Integration testing.
• A passion for learning new skills and technologies.
• A proactive, supportive, and collaborative team player.
