- Architect and implement reliable, intuitive solutions for: Physical and virtual card issuance, activation, and control
- Architect and implement reliable, intuitive solutions for: 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
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
Team
Structure: cross-functional domain team (Backend, Mobile, ML/AI, QA, Design, and Product)
