Front-End Engineer (React)

Quanloop is building and running a security‑sensitive investment platform. We are hiring multiple Front-End Engineers (React) in Budapest to build and evolve the web UI and ship user-facing features with predictable behaviour and clean integration.

Your home office is Budapest and the role is office‑first.

This is a React-focused engineering role. You will work closely with Back-End Engineers (Java) and UI Developers (HTML/CSS) to deliver complete features without unnecessary handoffs.

Role Snapshot

• Working model: Office‑first (on‑site).
• Hiring basis: Local hiring for the Budapest office location.
• Onboarding: Budapest is the home office.
• Language: English‑first working language.
• Reporting line: You report to a Tech Lead; Tech Leads report into Head of Engineering and/or the CTO.

What You’ll Be Responsible For

• Build and maintain React UI for product features and workflows.
• Integrate UI with backend APIs and handle edge cases cleanly.
• Work with UI Developers (HTML/CSS) on implementation details, consistency and accessibility basics.
• Keep UI code maintainable: clear structure, reviewable changes and predictable behaviour.
• Partner with Product Owner and QA on scope, acceptance criteria and release readiness.
• Collaborate with Infrastructure on constraints that affect front-end delivery (performance, operational readiness, and safe change).
• Contribute to practical documentation and written decisions where it helps teams move.

What We’re Looking For

• Strong commercial experience building production React applications.
• Comfortable integrating UI with APIs and handling real-world complexity (not toy examples).
• Solid HTML/CSS fundamentals (you don’t need to be the HTML/CSS specialist, but you must understand the basics).
• Comfortable with code review and shared engineering standards.
• Fintech or regulated/high‑scrutiny environment experience is preferred.
• Clear written and spoken communication in English.
• Comfortable working on site with a team.
