About Moneybox

At Moneybox, our mission is to give everyone the means to get more out of life. We're guided by our belief that wealth isn't about the money, it's about the means to more - more freedom, opportunities, possibilities, and peace of mind. Moneybox is an award-winning wealth management platform, helping over one and a half million people build wealth throughout their lives, whether they’re saving and investing, buying their first home, or planning for retirement.

The Role
We are looking for a Senior iOS Developer to join our mobile team. In this role, you will be a key individual contributor within a squad, driving feature delivery and technical excellence. While you will focus on high-quality code production, you should be open to taking on broader responsibilities, including the potential to manage or mentor other engineers as the team and our squads evolve.

We operate a Hybrid/Remote working model, providing flexibility while maintaining a strong team connection.

What you’ll do

Technical Ownership: Lead and deliver streams of work end-to-end, taking ownership from initial requirements and API design through to store release and post-release monitoring.
Platform Evolution: Partner with mobile leadership to shape the technical direction of the iOS platform, including architecture, tooling, and engineering standards.
Modern Engineering: Drive the adoption of SwiftUI and Swift Concurrency across the app, while confidently navigating and migrating legacy UIKit components.
Cross-Functional Collaboration: Work closely with Product Managers to define features, Backend engineers to design RESTful APIs, and UI/UX designers to bring high-fidelity interfaces to life. You will also collaborate with the Android team to ensure feature parity and shared architectural standards where appropriate.
Mentorship & Growth: Actively support the development of other engineers through technical guidance and code reviews. You should be open to taking on line management responsibilities as the team continues to grow.
High-Fidelity UI: Champion accessibility and inclusive design, ensuring our features are fully optimized for VoiceOver, Dynamic Type, and high-contrast settings.
AI-Augmented Development: Thoughtfully integrate AI tooling into your workflow to increase velocity. You will help the team adopt these tools responsibly, maintaining a high bar for critical review and architectural integrity.

What we’re looking for

Essential

iOS Expertise: Significant professional experience building native iOS apps with a deep command of Swift, SwiftUI, and Swift Concurrency.
Framework Proficiency: Solid working knowledge of UIKit for maintaining legacy code and supporting migration to SwiftUI.
Persistence & Data: Strong working knowledge of CoreData. You understand how to manage complex data models and local persistence in a performance-critical environment.
Architectural Leadership: A proven ability to make high-impact technical decisions using SOLID principles and architecture patterns such as MVVM-C (Coordinator-based navigation), and to navigate complex systems, including Server-Driven UI and modular codebases.
Critical AI Integration: You use AI tools to enhance your productivity but maintain a rigorous standard for the code you ship. You have the critical sense to identify when AI solutions require manual refinement for security or logic.
Inclusive Engineering: Experience implementing iOS accessibility features. You understand how to build interfaces that remain functional and accessible across different text scales, motion settings, and assistive technologies.
Leadership Mindset: A genuine interest in the people side of engineering. You are comfortable providing feedback and are willing to take on line management responsibilities if the opportunity arises.
CI/CD & Delivery: A solid understanding of automated testing, CI/CD pipelines, and the mobile release lifecycle.
Mission-Driven: A genuine interest in financial technology and a desire to build a product that helps a million+ users reach their financial goals.

Desirable

Security & Cryptography: Experience with secure coding practices, encryption, and handling sensitive financial data.
Modular Architecture: Experience working within multi-framework codebases to support parallel development across multiple squads.
Complex UI: Experience with custom native animations or high-performance UI interactions.

Our Commitment to DE&I:

At Moneybox, we promote, support and celebrate inclusion, diversity and equity for all, so that everyone can bring their full selves to work. We believe that diversity drives innovation, and that if our team is representative of our community of customers, we can better support their needs. To ensure our recruitment processes provide an equal opportunity for all applicants to succeed, we encourage you to let us know if there are any adjustments that we can make. We are open-minded and always willing to go the extra mile to ensure all applicants can present their full self and potential

Working Policy:

We have a hybrid policy that includes 2 days from our London office and 3 from home. If the role states it is either hybrid or remote candidates must be based within the UK.

Visa Sponsorship:

At this time we cannot offer visa sponsorship for this role and we cannot consider overseas applications.

Please read before you apply!

Please note if offered a position, the offer is conditional and subject to the receipt of satisfactory pre-employment checks which we will conduct such as criminal record and adverse credit history checks. As a regulated financial business, an adverse financial history could impact your suitability for the role.
