The Role
How We Build
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
Curiosity.
Business acumen.
Communication.
T-shapedness.
Ownership.
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.
