Role Overview

  • We are looking for a strong Mid-Level Front-end Developer to build a new application from scratch.
  • The project will focus on a clean, reactive UI that consumes backend data.
  • The solution is technically straightforward, but must be well-designed, maintainable, and easy to understand — as the codebase will be handed over internally after the contract ends.
  • You will work closely with the feature leader, who will define requirements and architecture. Your responsibility will be to independently implement high-quality frontend solutions based on provided user stories and technical direction.
  • This role requires ownership, technical maturity, and real understanding — not just assembling code with AI or copying patterns without knowing why.


Key Responsibilities

  • Build a React + TypeScript application from scratch + integrate it with backend APIs
  • Write clean, maintainable, well-structured code
  • Implement unit tests (using Jest or similar)
  • Structure the project in a scalable and understandable way
  • Deliver features independently based on provided requirements
  • Communicate progress transparently
  • Understand the “why” behind implemented solutions


What We Expect

Technical Skills

  • Strong hands-on experience with React + TypeScript
  • Ability to set up a frontend project from scratch
  • Good understanding of frontend architecture patterns
  • Someone with Banking experience is Good to have.
  • Experience building reactive UIs (frequently updating data)
  • Solid knowledge of REST APIs
  • Experience with testing frameworks (Jest or similar)
  • Strong CSS skills and ability to structure styles properly
  • Understanding of modern frontend tooling and ecosystem
  • Ability to evaluate trade-offs between technical approaches
  • Clean code mindset (readability > cleverness)
  • We are looking for someone who:
  • Understands the code they write
  • Can explain architectural decisions
  • Uses AI as a tool — not as a substitute for understanding


Soft Skills & Work Style

  • Self-sufficient and reliable
  • Delivers on time with good quality
  • Transparent in communication
  • Understands business context of implemented features
  • Comfortable working under technical supervision
  • Proactive in raising risks or doubts
