Senior iOS Developer (Remote) at Finom in Poland, PL

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.

We're looking for a Senior iOS Engineer who thinks like a product builder — someone who cares deeply about the "why" behind what they're building, not just the tickets in the backlog.

You'll be embedded in a cross-functional domain team (Backend, Mobile, ML/AI, QA, Design, and Product) and own the end-to-end development of features that genuinely matter: company accounts and cash flows, banking transactions, card issuance and management, and AI-enabled accounting. You'll help shape architecture decisions, raise the bar on engineering quality, and mentor the engineers around you.

If you're energized by working at the intersection of great mobile engineering and real product impact — this is the role.

What You'll Do

• Design and build new features for our iOS application, used daily by business owners across Europe.

• Architect and implement reliable, intuitive solutions for:

• Multi-account cash flow management

• Banking transactions and payments

• Physical and virtual card issuance, activation, and control

• AI-powered accounting automation

• Build polished, responsive UIs using UIKit and SwiftUI.

• Take ownership of code quality, performance, and stability — automated testing and thorough code reviews are non-negotiable.

• Collaborate closely with Backend, QA, Design, and Product — you'll be shaping solutions end-to-end, not just implementing specs.

• Drive technical decisions within your domain, challenge assumptions when needed, and proactively identify opportunities to build better.

• Contribute to CI/CD pipelines, tooling, and mobile best practices across the team

Who You Are

You're pragmatic and have a proven track record of shipping products that matter. You communicate clearly across disciplines and thrive in a cross-functional environment where everyone is solving the same customer problem together.

Your experience includes:

• Strong knowledge of the Swift language and at least 3 years of commercial iOS development.

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

• Practical experience using the VIPER architectural pattern and the Coordinator navigation pattern.

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

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

• Confidence with Git / GitLab, including the ability to set up and use GitLab CI/CD.

• Ability to write unit and UI tests.

• A builder's mentality — you care about the product, the users, and the outcomes, not just the code.

• Clear, concise communication in English across technical and non-technical audiences.

Nice to Have

• Background in fintech or experience with financial products — you understand the stakes.

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

• Experience profiling and optimizing UI performance — reducing rendering bottlenecks and achieving 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.

• Hands-on experience with AI agents and LLM tools (Claude, Cursor, Copilot, etc.) — setting up agent environments, writing prompts, skills, and behavioral rules.

• Experience with AI-powered IDE tools (Cursor, Windsurf, GitHub Copilot, Claude Code, etc.) — including agent mode, rules files configuration, and integrating AI into the daily development workflow.

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

• Ability to evaluate and verify AI-generated output — using automated tests, linters, and critical review to catch hallucinations and errors.

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