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
- This is not a role for a junior developer, and not a purely senior architectural position.
- We are looking for a strong mid-level engineer who can execute independently and responsibly.
