About the Role

Level: 4

Department: Quilter Invest – Marketing and Distribution

Location: England Home Worker

Contract type: Permanent

Who are we?

We’re Quilter Invest, a scale up FinTech app that’s pioneering the future of wealth management with cutting‑edge solutions tailored for a new generation of investors. Our mission is to empower individuals to take control of their financial future through smart, intuitive tools that make investing and saving easy and accessible.

We began as a startup called Wombat Invest in 2020, and after various rounds of funding, have now successfully been acquired by Quilter plc to provide more investing and savings offerings to their customer base, and help bring new customers on board. We’re currently scaling up fast so we can position ourselves as a leading FinTech product in the market.

What’s the position?

As a Senior iOS Developer at Quilter Invest, you will be at the forefront of building intuitive and secure mobile applications that enhance our users' financial journeys. You will collaborate with cross‑functional teams, develop high quality features, and help drive the technical direction of our iOS projects.

What are my roles and responsibilities?

• Building new features and fixing bugs
• Collaborating with product managers, designers, and other stakeholders to define app requirements and user experience.
• Writing Unit and UI tests for existing and new features
• Keeping documentation up to date and helping us expand it
• Troubleshooting, debugging, and optimising application performance.
• Staying updated with the latest industry trends, technologies, and best practices in iOS development.

What’s the tech stack?

We currently use Swift 5 + MVVM + UIKit as our foundations, and we’re beginning to integrate SwiftUI + Async Await into our codebase, so these are essential skills to have. We’re always open to new ideas to improve the tech, so if you’re a self‑starter you’ll be very welcome here.

Can I work remotely?

From anywhere in the UK! We have people in London, Brighton, Northern Ireland, Manchester, Leeds and more. As long as you’re in the UK and have internet, you can work wherever you want.

What’s it like working at Quilter Invest?

We’ve always been a small team, but as we’re currently scaling up, we’ll almost be doubling our development team. That means you’ll be joining a welcoming and close‑knit team who have been at the company for many years and joining an expanding team at the same time. We’ll be going from three developers on each mobile platform, to six each. We use Slack within Quilter Invest for fast communication, and Teams to stay in contact with the broader Quilter company. As we’ve always been remote, we make an effort to stay connected to each other, and every now and then we’ll do an optional office day at our headquarters in Bank, London.
