</li><li>Mobile Strategy: Shape the strategic direction of our mobile product, identifying unique mobile-first advantages and ways to differentiate the app from our web experience.
</li><li>API Design: Work alongside backend engineers to design clean, resilient API contracts that allow the application to remain fast and easily adaptable.
</li><li>Performance &amp; Stability: Continuously optimize app health, focusing on launch times, smooth navigation, rendering, networking efficiency, offline functionality, and error handling.
</li><li>Analytics &amp; Observability: Implement comprehensive telemetry and instrumentation to empower product and engineering teams to track user behavior and iterate confidently based on data.
</li><li>Technical Leadership: Set a high bar for engineering excellence through rigorous code reviews, thoughtful architecture decisions, and pragmatic engineering standards.
</li><li>Scale the Platform: Build out the long-term mobile platform roadmap, establishing how our codebase, developer workflows, and team structure will scale over time.
</li><li>Team Building: Act as a foundational leader for the iOS org, helping attract, mentor, and grow a world-class team around you.
</li><li>Product Contribution: Bring strong opinions on mobile UX, proactively suggesting user experience improvements and weighing smart technical tradeoffs rather than just writing code.</li> 
</ul>Tech Stack
<ul><li>iOS: Swift, SwiftUI, UIKit
</li><li>Backend: Ruby on Rails, Node.js
</li><li>Data: Postgres, MongoDB
</li><li>Infra / Observability: AWS, Datadog
</li><li>Testing: XCTest, UI Testing, CI/CD pipelines</li> 
</ul>Candidate Profile
<ul><li>Experience: 5+ years of experience developing production-grade iOS applications featuring significant consumer-facing scale, high complexity, and polished design.
</li><li>Technical Mastery: Exceptional command of Swift and contemporary iOS design patterns.
</li><li>Craftsmanship: Proven track record of shipping fluid native experiences with a sharp focus on responsiveness, fluid animations, performance, and handling edge cases.
</li><li>Architectural Influence: Experience leading or heavily contributing to the architectural layout of a substantial iOS application.
</li><li>Product Mindset: Deep care for product quality, with the ability to translate complex business workflows into elegant, seamless user interactions.
</li><li>Agility: The ability to move quickly and deliver features without accumulating technical debt or long-term structural fragility.
</li><li>Systems Collaboration: Comfortable partnering with backend teams on data contracts, API design, and system-wide tradeoffs.
</li><li>Engineering Rigor: Strong foundational habits around code quality, test coverage, system observability, release safety, and operational accountability.
</li><li>Zero-to-One Drive: Motivated by greenfield projects and eager for broad ownership rather than a narrow, siloed scope.
</li><li>Pragmatism &amp; Taste: Excellent judgment on when to push for perfection, when to simplify, and how to execute smart tradeoffs in a fast-paced environment.
</li><li>Background: Ideally, you have built high-caliber consumer products within elite startups or top-tier engineering organizations known for execution excellence.
</li><li>Culture Add: A thoughtful, low-ego, and collaborative teammate. We believe building a company is a team sport and value a highly ambitious yet supportive culture.</li>

Team description
 
The Consumer team builds and maintains SumUp Pay — a regulated consumer banking app spanning payments, card management, savings, and open banking, used by hundreds of thousands of customers every day. We're a cross-functional squad of engineers, product managers, and designers working at pace on a product that genuinely matters to the people who rely on it. Right now, we're growing our iOS function to match the ambition of our product roadmap — and this role sits at the heart of that.
 
As an iOS Engineer, you'll own meaningful parts of the SumUp Pay experience end-to-end, from onboarding and KYC flows through to savings features and in-app messaging. With a lean iOS team and a growing product surface, there's real scope to shape how we build — not just what we build.

Design, build, and ship iOS features across SumUp Pay — including KYC and card activation flows, savings, open banking consent, and payment experiences
 
Take ownership of performance monitoring, crash reporting, and app stability, proactively resolving issues before they reach customers
 
Contribute to the evolution of our iOS architecture — including modularisation, dependency management, and scalability as the product grows
 
Partner with the CRM Manager to implement in-app messaging (modals and banners) via Iterable, ensuring correct event instrumentation and display logic on iOS
 
Write clean, testable Swift code and contribute actively to code reviews, CI/CD pipeline health, and a culture of quality across the team
 
You'll be great for this role if…
 
Strong proficiency in Swift and the iOS framework, with a track record of shipping consumer-facing features in a product environment.
 
Experience integrating RESTful APIs and collaborating closely with backend engineers on API design and contracts.
 
Solid understanding of iOS architecture patterns, modularisation, and writing maintainable, well-tested code.
 
Comfort working in a regulated or fintech environment, with an appreciation for the security, compliance, and data privacy considerations that come with it.
 
A product-oriented mindset — someone who thinks about the user journey, not just the implementation, and brings both craft and pragmatism to technical decisions.
 
Why you should join SumUp
 
Opportunity to work with a truly global, multicultural team from our central Covent Garden location, wrapped in historic charm and modern flair. This involves an office-first setup
 
Commitment to Diversity and Inclusion: be part of a workplace that values and promotes diversity, fostering an inclusive environment where everyone's perspectives are respected and embraced

Wise

<div>Company Description 
Wise is a global technology company, building the best way to move and manage the world&rsquo;s money. 
Min fees. Max ease. Full speed.
Whether people and businesses are sending money to another country, spending abroad, or making and receiving international payments, Wise is on a mission to make their lives easier and save them money.
As part of our team, you will be helping us create an entirely new network for the world's money. 
For everyone, everywhere.
More about our mission and what we offer. 
Job Description 
About the role:
Wise moves billions every month. Every single transfer runs through Send Experience.
We own the send flow end-to-end: the product millions of customers touch, the discovery layer that makes local payment networks like Pix and UP feel native, and the platform holding tens of millions of recipient accounts worldwide. Three teams. One of the highest-impact surfaces in fintech.
We're making international transfers feel as easy as sending a message. As an iOS product engineer, you won't just build that &mdash; you&rsquo;ll decide what it looks like.
Our mission is to make sending money as easy as possible. As an iOS engineer, you&rsquo;ll be working on making the app experience truly exceptional. International at heart, feeling local and frictionless.
How we work:
We&rsquo;re a team split between London and Tallinn. We follow a hybrid working model, ensuring enough collaboration in-person and focus time where people find it best.
What will you be working on?:
Over 10 million customers will use what you build. That's not a vanity metric, it&rsquo;s the weekly reality.
The role is UI- and product-focused. The work is deeply creative: flows that need to feel effortless whether it's a first transfer from S&atilde;o Paulo, or a hundredth from London. Where animation timing, information hierarchy, and interaction design are real engineering problems &mdash; not afterthoughts.
And this is not a ticket factory. You'll sit with product and design from day one of an idea, challenge what &quot;best&quot; looks like, and ship your answer. The strongest features we've built started with an engineer saying &quot;what if we did it this way instead.&quot; We need more of that.
Concretely:<ul><li>
Craft send experiences that feel local everywhere</li><li>
Build the future of recipient discovery: search, QR scanning, and more</li></ul><ul><li>
Push what our iOS app can do, with thoughtful transitions, responsive interfaces, and micro-interactions that make people smile</li><li>
Own features end-to-end, from technical design to watching real customers use your work</li><li>
Raise the bar across Wise by collaborating with 60+ mobile engineers to lift UX and code quality across the entire app</li></ul>
What do you need?:
We know it's rare to tick every box. If you have most of these and are hungry to learn the rest, you should apply.<ul><li>
You've built app experiences people love and can show it</li><li>
Strong in Swift</li><li>
A genuine eye for craft: you notice when a transition is 100ms too slow or a layout doesn't breathe</li><li>
You think in customer problems, not tickets: you push back when something doesn't make sense and propose what should exist instead</li><li>
Familiar with architectural patterns like MVVM or VIPER (we use both, happy to explore others)</li><li>
You write testable code and care about what happens after you merge Solid understanding of REST APIs, you're comfortable at the boundary between mobile and backend</li><li>
You communicate clearly: technical ideas to non-technical people, strong opinions held loosely</li><li>
You work autonomously, but you make the people around you better too</li></ul>
Nice to Have:<ul><li>
Experience with SwiftUI, Structured Concurrency, or CI/CD pipelines (GitHub Actions)</li><li>
Familiarity with internationalisation patterns for apps serving many markets</li><li>
A fintech background &mdash; but absolutely not required</li></ul>
