Join DKB Code Factory as a Senior Frontend Engineer and take on a pivotal role shaping the user experience of our core digital products. You will own the implementation and quality of customer-facing interfaces used by millions of users, collaborating closely with cross-functional teams to enhance usability and drive conversion, while advancing modern testing practices and efficient delivery across the frontend ecosystem.

} } ; 

{ your_responsibilities: [

• Own and deliver user-facing features end-to-end (UI + integration) with clear acceptance criteria, automated tests, and production monitoring.
• Drive measurable usability improvements for key flows using analytics and user feedback (e.g., increase task completion or reduce friction on target metrics).
• Establish and evolve reusable UI primitives and Storybook documentation to increase component reuse and reduce duplication across the product.
• Define and enforce frontend standards for testing, accessibility, and performance; integrate checks into CI to reduce regressions.
• Optimize critical user journeys for performance and reliability (Core Web Vitals, payload reduction, render optimisation).
• Mentor peers through code reviews, workshops, and knowledge shares to raise team frontend craftsmanship.
• Collaborate closely with Product, UX/UI Designers, Backend, QA, and DevOps to align technical choices with product outcomes

] } ;

{ following_qualifications_would_be_in_line_with_our_desired_profile_for_this_position: [

• Proven experience building production frontend applications using Vue and modern JavaScript/TypeScript, with strong understanding of UI architecture, component design, and state management patterns.
• Practical experience with REST API integration and client-server resilience patterns.
• Hands-on experience with testing and automation (preferred: Playwright, Vitest; familiarity with Jest/Selenium is a plus).
• Demonstrable knowledge of frontend performance optimization and measuring improvements (lab and field metrics).
• Familiarity with CI/CD pipelines, frontend build tooling (Vite/bundlers), and browser debugging tools.
• Experience using monitoring or observability tools (e.g., Grafana) to inform post-release actions

] } ;

Required:

• 3+ in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML — and ideally additional experience with native Windows code (C++, Win32/WinRT/COM).
• Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code.
• Proven track record of designing, building, and shipping production-quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability.
• Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software.
• Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming (where relevant).
• Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
• Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
• A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.

Preferred / Bonus:

• Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
• Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
• Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
• Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.
• Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.
• Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management.

What we offer

• A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.
• A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.
• Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect).
• Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision.
• A purpose-driven mission: building software that’s reliable, accessible, and user-centered — making a real difference for people.
