Job description

Welcome to DKB Code Factory….

Join DKB Code Factory as an iOS Engineer!

Are you passionate about building high-quality iOS apps? Do you enjoy designing scalable architectures, creating reusable components, and delivering impactful features from scratch? At DKB Code Factory, we’re looking for someone who doesn’t just code, but helps lay the foundation for products that drive real business impact and reach millions of banking customers.

As an iOS Engineer, you’ll play a key role in building a new mobile-first product for a distinct customer segment, shaping its core architecture, and delivering MVP flows that accelerate time-to-market. You’ll work closely with a growing cross-functional team, contributing to a product that moves the business forward and delivers measurable outcomes. If you’re excited to build from the ground up and make a tangible impact, let’s talk!

• Design, implement, and evolve the foundational iOS architecture, including navigation, state management, and API integration, delivering it as part of the MVP codebase.
• Identify, audit, and integrate shared components and modules, defining integration approaches and documenting trade-offs to maximize reuse and consistency across the product.
• Build and maintain a modular SwiftUI codebase supported by CI/CD pipelines, linters, and a comprehensive testing strategy, including unit, snapshot, and integration tests to ensure reliable releases.
• Deliver the majority of prioritized MVP user flows, such as onboarding, core interactions, and navigation, collaborating closely with Backend and Product to meet acceptance criteria.
• Drive performance optimizations and accessibility improvements, ensuring app launch time, memory usage, and accessibility standards remain within agreed targets.
• Mentor and support other iOS developers, contributing to onboarding, knowledge sharing, and establishing high-quality code review practices across the team.
• Take strong ownership of features and outcomes, defining acceptance criteria, monitoring release quality, and proposing incremental improvements to adapt efficiently to changing requirements.

• Proven production experience in Swift and SwiftUI, with solid knowledge of current iOS SDKs and Xcode workflows.
• Demonstrable experience designing modular iOS architectures (navigation patterns, state management) and integrating with REST/GraphQL APIs.
• Strong testing discipline: unit testing and integration testing implemented in CI pipelines.
• Experience setting up or working with CI/CD tools (e.g., GitHub Actions, GitLab CI, Bitrise, Fastlane) and automated build/test pipelines.
• Excellent collaboration skills, experience working in cross-functional product teams with Product, Design, and Backend.
• Track record of mentoring others and driving code quality through consistent PR reviews and engineering standards.
• Fluent English required; Spanish desirable.
