.css-10dm8y{font-size: inherit!important;margin-bottom: 16px;} Location: London, United Kingdom Team: Consumer
 
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.
 
What you'll do

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.

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

Zapp

<div>Principal Software Engineer, Mobile (React Native)
Nine Elms, London - Full-time (4 days a week on-site)
About Zapp
Zapp is London&rsquo;s leading premium convenience retail platform. Founded in 2020, our vision is to disrupt the multi-trillion dollar convenience retail market, currently dominated by major players, by developing best-in-class customer-centric technology and fulfilment solutions. Zapp partners with some of the world&rsquo;s leading brands to deliver an exclusive range of hand-picked products 24/7, delivered in minutes.
Quick commerce is a genuinely hard mobile problem. Stock changes by the second, orders and riders move in real time, and we make sub-minute promises we have to keep, all on patchy high-street connections across a huge range of devices. Getting that right, fast and reliably, is the job.
We are serious about AI, as a way of working rather than a slogan. AI-assisted development is part of the daily toolkit here, and we ship LLM-powered features where they genuinely make the product better.
The Role
As Principal Mobile Engineer you own the technical direction of our consumer iOS, Android and web apps, all built on React Native. This is a deliberately hands-on Principal role. You set the architecture and the standards, and you are still in the code every week shipping the hardest parts yourself. You will be the most senior mobile engineer in the company and the person the rest of the team levels up against.
You will work closely with stakeholders in Commercial, Marketing and Operations to shape what we build and make sure the app serves the whole business.
What you'll do<ul><li>
Own the architecture of the React Native app across iOS, Android and web, and make the calls on patterns, tooling and technical direction</li><li>
Stay hands-on: ship the hardest features yourself and set the standard for what good looks like in the codebase</li><li>
Raise the engineering bar across the mobile team through sharp code review, mentoring, and the example you set</li><li>
Drive performance, stability and responsiveness, profiling and fixing the things that actually hurt on real devices and real networks</li><li>
Own the release process and the health of what we put in front of customers</li><li>
Partner with the wider business and the leadership team to turn ideas into fast, reliable, polished experiences</li><li>
Work across the stack where it helps, into the backend APIs and data layers that feed the app</li><li>
Use AI tooling (Claude, Cursor, Copilot) to ship faster and help the team get genuinely good at it, and build AI-powered features with LLM and on-device capabilities where they improve the product</li></ul>
What you'll bring
Essentials<ul><li>
A track record of building and shipping B2C consumer mobile apps at scale, and being the person who sets technical direction for a mobile team</li><li>
Deep React Native expertise across iOS and Android, with the judgement to know its limits and drop into native when needed</li><li>
Strong TypeScript</li><li>
Real command of mobile performance, stability and release processes</li><li>
Solid grasp of mobile security: secure storage, authentication patterns, and API security</li><li>
You take genuine end-to-end ownership and operate autonomously</li><li>
You communicate clearly, in writing and in person, and can bring people with you on a technical call rather than just winning the argument</li></ul>
You have probably been doing this for 7 or more years, but we care about the impact you have had, not the number on your CV.
Nice to have<ul><li>
Node.js (Express, Fastify) for the API layer</li><li>
React.js or React Native for Web</li><li>
Native experience (Kotlin, Swift) for the bridge and the trickier native modules</li><li>
GraphQL, GCP, Firestore, Event-Driven architecture</li><li>
Hands-on experience building with LLM or AI APIs</li></ul>
Benefits<ul><li>
Competitive salary, plus meaningful equity</li><li>
25 days holiday, plus all bank holidays</li><li>
Private health insurance</li><li>
Extended sick pay and enhanced maternity and paternity leave</li><li>
Cycle to work scheme</li></ul></div>

Senior Engineering Program Manager, Customer Engagement - Apple Service

Voxquill

<div>I'm looking for our founding engineer!
 
The person who takes a live, paying fintech product and makes it truly ours.
We build receipt-and-proof automation for the self-employed: the app quietly finds your receipts (email, bank feeds, camera roll, texts), sorts them, matches them to your bank transactions, and produces accountant-ready exports. It's live on iOS and Android, it's SOC 2 certified, and people are paying for it. The model works.
I need one person who treats this codebase as theirs, ships fast, and owns the platform end-to-end. This is a founding engineer role with a real path to CTO.
Your first job is to take the keys.
 
Move the platform off the agency's Azure into ours, take custody of production, and the headline deliverable.
 
Build the automated test suite this codebase never had, with a CI/CD pipeline where a green build genuinely means &quot;safe to ship.&quot; Then you own the roadmap.
How we build matters as much as what we build.
 
We are not rebuilding an IT shop of tickets and manual QA.
 
Terrapin runs as an AI-native pod: Claude Code and agents do the repetitive work and produce tested, PR-ready changes; you own architecture, review, security, and the hard 20%.
 
AI gives you the velocity, your tests and pipeline are what keep that velocity from turning into breakage!
We want to ship multiple times a week and almost never break anything, and hold our SOC 2 line the whole way. If that model excites you rather than worries you, you're the person.
This is genuinely full-stack.
 
Strong .NET / C# backend on Azure, real ownership of infra, security, and DevOps, and polished mobile (React Native + Expo, iOS and Android); Because the app is the product. Testing isn't someone else's job here. It's the core discipline.
The kind of person whose teammates would describe as:<ul><li>
an owner, not a ticket-taker</li><li>
obsessive about shipping quality fast</li><li>
calm owning production for a product with real money moving through it</li><li>
someone who builds automation instead of doing the same thing twice</li><li>
security-minded by instinct, not as an afterthought</li></ul>
What you'd bring:<ul><li>
Senior+ .NET / C# backend, PostgreSQL, solid API design</li><li>
Real Azure ownership: App Services, networking, Key Vault, identity, CI/CD (Azure DevOps or similar)</li><li>
Strong React Native + Expo mobile, with genuine UI/UX taste</li><li>
Test automation and CI/CD as a way of life &mdash; you write the tests with the code</li><li>
Hands-on building with Claude Code / agent tooling, and doing it safely in a SOC 2 world</li></ul>
Bonus points: fintech / payments background, Plaid experience, or applied LLM work.
And the reason the right engineer will actually stay: receipts are just the wedge. We're building toward a verifiable, tamper-evident record of an economic event. Proof that banks, insurers, and AI agents can consume directly. Stripe is a payment rails. We're building proof rails.
You'd work directly with me every day &mdash; 18+ years in fintech and payments, two exits behind me &mdash; so you own the engineering but never carry the hard architecture, security, or product calls alone.
The details:
 
UK or EU-remote(temporarily), with solid overlap to UK hours and business trips.
We're genuinely open to strong candidates across both. Being open to relocating to the UK down the line is a plus, but not a day-one requirement.
 
Competitive base plus real founding-level equity.
One hard line: you build quality in through tests and CI/CD. We're deliberately leaving the manual-testing, hope-it-works world behind, and a dev who treats testing as optional isn't the hire. Everything else, we can talk about.
If you want founder-level ownership, a CTO trajectory, and an AI-native way of building, and owning a live fintech platform from week one lights you up, let's talk.
Apply and tell me about something you shipped that you're proud of, and one thing you broke and how you made sure it never happened again.</div>
