Finom is hiring a Senior iOS Developer

Requirements

  • 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.
