Team description
<br><br>
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.
<br><br>
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.
<br><br>

<br><br>
Design, build, and ship iOS features across SumUp Pay — including KYC and card activation flows, savings, open banking consent, and payment experiences
<br><br>
Take ownership of performance monitoring, crash reporting, and app stability, proactively resolving issues before they reach customers
<br><br>
Contribute to the evolution of our iOS architecture — including modularisation, dependency management, and scalability as the product grows
<br><br>
Partner with the CRM Manager to implement in-app messaging (modals and banners) via Iterable, ensuring correct event instrumentation and display logic on iOS
<br><br>
Write clean, testable Swift code and contribute actively to code reviews, CI/CD pipeline health, and a culture of quality across the team
<br><br>
You'll be great for this role if…
<br><br>
Strong proficiency in Swift and the iOS framework, with a track record of shipping consumer-facing features in a product environment.
<br><br>
Experience integrating RESTful APIs and collaborating closely with backend engineers on API design and contracts.
<br><br>
Solid understanding of iOS architecture patterns, modularisation, and writing maintainable, well-tested code.
<br><br>
Comfort working in a regulated or fintech environment, with an appreciation for the security, compliance, and data privacy considerations that come with it.
<br><br>
A product-oriented mindset — someone who thinks about the user journey, not just the implementation, and brings both craft and pragmatism to technical decisions.

IOS Developer

Voxquill

<div><p>I'm looking for our <b>founding engineer</b>!
<br>
The person who takes a live, paying fintech product and makes it truly ours.</p><p>
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.</p><p>
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 <b>real path to CTO</b>.</p><p><b>
Your first job is to take the keys.</b>
<br>
Move the platform off the agency's Azure into ours, take custody of production, and the headline deliverable.
<br>
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.</p><p><b>
How we build matters as much as what we build.</b>
<br>
We are not rebuilding an IT shop of tickets and manual QA.
<br>
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%.
<br>
AI gives you the velocity, your tests and pipeline are what keep that velocity from turning into breakage!
</p><p>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.</p><p><b>
This is genuinely full-stack.</b>
<br>
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 <i>is</i> the product. Testing isn't someone else's job here. It's the core discipline.</p><p><b>
The kind of person whose teammates would describe as</b>:</p><ul><li><p>
an owner, not a ticket-taker</p></li><li><p>
obsessive about shipping quality fast</p></li><li><p>
calm owning production for a product with real money moving through it</p></li><li><p>
someone who builds automation instead of doing the same thing twice</p></li><li><p>
security-minded by instinct, not as an afterthought</p></li></ul><p><b>
What you'd bring:</b></p><ul><li><p>
Senior+ .NET / C# backend, PostgreSQL, solid API design</p></li><li><p>
Real Azure ownership: App Services, networking, Key Vault, identity, CI/CD (Azure DevOps or similar)</p></li><li><p>
Strong React Native + Expo mobile, with genuine UI/UX taste</p></li><li><p>
Test automation and CI/CD as a way of life &mdash; you write the tests with the code</p></li><li><p>
Hands-on building with Claude Code / agent tooling, and doing it safely in a SOC 2 world</p></li></ul><p><b>
Bonus points</b>: fintech / payments background, Plaid experience, or applied LLM work.</p><p>
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. <b>Stripe is a payment rails. We're building proof rails.</b></p><p>
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.</p><p><b>
The details:</b>
<br>
UK or EU-remote(temporarily), with solid overlap to UK hours and business trips.
</p><p>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.
<br>
Competitive base plus real founding-level equity.</p><p><b>
One hard line</b>: 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.</p><p>
If you want <b>founder-level ownership</b>, a CTO trajectory, and an AI-native way of building, and owning a live fintech platform from week one lights you up, <b>let's talk</b>.
</p><p>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.</p></div>
