Senior iOS Developer (Remote)

About Finom

Finom is a European tech startup headquartered in Amsterdam, and we’re on a journey towards revolutionizing the financial landscape for entrepreneurs worldwide. Our mission is to develop an all-in-one financial B2B solution that integrates banking functions, accounting, financial management, and invoicing into a seamless, mobile-first platform.

We recently closed a €115 million Series C equity round (around $133 million), bringing our total funding to approximately $346 million. This significant investment follows a $105 million growth funding round from General Catalyst, a long-term backer since 2021 known for supporting companies like Airbnb, HubSpot, KAYAK, and Stripe.

Finom's platform goes beyond traditional banking, offering invoicing and a growing suite of features, including AI-enabled accounting, aiming to simplify financial management for entrepreneurs. We're actively expanding our reach across key EU markets like Germany, France, the Netherlands, Italy, and Spain.

At Finom, we’re not just redefining the entrepreneurial experience — we’re empowering our employees to make a real difference. Your work matters, and your impact extends far beyond product metrics. We nurture innovation and an inspiring work environment where bold ideas thrive, prioritizing thorough research, swift implementation of solutions, and ensuring that every effort we make benefits our users, employees, partners, and our business as a whole.

Maintaining our start-up spirit, we prioritize thorough research, swift implementation of solutions, and ensuring that every effort we make benefits our users, employees, partners, and, of course, our business.

The Role

For hundreds of thousands of European entrepreneurs, our iOS app is Finom. It's how they check their cash flow over morning coffee, approve a payment between client meetings, and freeze a card the moment something looks off. We're mobile-first by conviction, not convenience — the app isn't a companion to the "real" product; it is the product. And as an AI-native platform, the features you build increasingly carry intelligence inside them: AI-powered accounting, smart categorization, and agentic workflows that quietly save business owners hours every week. When you ship something great, someone somewhere feels it the same day.

That's why we're not looking for someone to implement tickets. We're looking for a Senior Mobile (iOS) Engineer who thinks like a product builder — someone who cares deeply about the "why" behind what they're building, challenges assumptions when needed, and proactively spots opportunities to create better outcomes.

You'll be embedded in a cross-functional domain team — Backend, Mobile, ML/AI, QA, Design, and Product — that owns a shared product area end-to-end. No handoff culture, no "not my layer": everyone in the team is solving the same customer problem, and you'll shape solutions from the first product conversation to the moment the feature is live in users' hands. Fewer silos means more flow — and real, end-to-end ownership.

What You Will Be Doing

How We Build

Agentic development is table stakes at Finom — for every craft, mobile included. Our engineers work with Claude Code and similar harnesses daily, and we've made it a first-class part of how the company operates, not an individual productivity hack. We follow a shared SDLC approach built around Spec-Driven Development (SDD): features start as clear, reviewable specs that both humans and AI agents execute against, powered by a shared AI development toolbelt and a growing library of skills, rules, and context maintained across guilds. You won't be figuring out AI-assisted development alone — you'll join an engineering organization that has already invested in the infrastructure, standards, and shared practices, and you'll be expected to use them, improve them, and raise the bar for others.

What You'll Do

• Design and build new features for our iOS application, used daily by business owners across Europe: multi-account cash flow management, banking transactions and payments, physical and virtual card issuance and control, and AI-powered accounting automation.

• Own outcomes, not just code. You'll follow your features into analytics, jump into customer issues without being prompted, and care about whether what you shipped actually moved the needle.

• Build polished, responsive UIs with UIKit and SwiftUI — in a financial app, trust is built (or lost) in the details.

• Drive technical decisions within your domain, discuss trade-offs openly with product managers, and explain constraints clearly to non-technical stakeholders.

• Raise the bar on engineering quality — automated testing, thorough code reviews, and mobile security best practices are non-negotiable in a regulated fintech.

• Mentor the engineers around you and contribute to CI/CD pipelines, tooling, and mobile best practices across the team.

Who You Are

Who You Are

You're pragmatic, learn quickly, and have a proven track record of shipping products that matter. Above all, you're curious — about the product, the users, the business, and how your technical decisions impact all three.

Curiosity. You want to understand the "why" behind every feature. You ask what problem it solves, question whether there's a simpler path, and explore how your decisions ripple into product, users, and revenue.

Business acumen. You connect your work to company objectives. You understand the "so what" behind every decision, and you'd rather ship the feature that moves the right metric than the one that's merely interesting to build.

Communication. You communicate clearly and concisely in English across technical and non-technical audiences — from fellow engineers to PMs to business stakeholders — and you genuinely enjoy the dynamics of a cross-functional team.

T-shapedness. Your iOS craft runs deep, but your curiosity runs wide. You'll peek at the backend contracts, ask questions about the ML models, and dive into analytics to understand how your features perform.

Ownership. You take responsibility not just for your code, but for the outcomes. You move without being prompted — whether that's improving team processes, jumping on a production issue, or mentoring a colleague.

Your Experience Includes

• 5+ years of commercial iOS development with strong knowledge of Swift.

• Deep understanding of OOP, SOLID principles, and design patterns.

• Practical experience with the VIPER architectural pattern and the Coordinator navigation pattern — and the judgment to know when a simpler approach serves the product better.

• Excellent knowledge of UIKit and experience (or a strong desire to grow) with SwiftUI.

• Experience with layout development in code, particularly using SnapKit or similar tools.

• Ability to write unit and UI tests.

• Confidence with Git / GitLab, including setting up and maintaining GitLab CI/CD.

• Hands-on experience with agentic development tools (Claude Code, Cursor, Copilot, or similar) as part of your daily workflow — writing prompts, configuring rules and skills, and critically evaluating AI-generated output with tests, linters, and review. This is table stakes for all engineering crafts at Finom, mobile included.

• A builder's mentality: you care deeply about shipping great products, not just writing great code.

Nice to Have

• Background in fintech or financial products — you understand the stakes of working in a regulated environment.

• Solid grasp of mobile security best practices (especially critical in our domain).

• Experience profiling and optimizing UI performance — reducing rendering bottlenecks and hitting smooth 60/120fps on iOS.

• Hands-on work with performance tooling: Instruments, XCTest, or similar.

• Published apps on the App Store you're proud of.

• An active GitHub profile with code you're happy to share.

• Deeper agentic engineering experience beyond daily tool use — setting up agent environments and harnesses, authoring reusable skills and behavioral rules, or contributing to a team's shared AI development practices.

• Understanding of model capabilities and limitations — knowing which model fits which task and how to manage the context window effectively.

• Awareness of AI security risks — prompt injection, data leakage, and safe handling of untrusted inputs in agentic workflows.
