Balancify

Frontend Developer (Next.js)

We’re looking for a Frontend Developer who has experience dealing with large volumes of real-time data on the frontend with a strong knowledge in state management and in balancing SSR and CSR - optimizing both in cost and UX.

 

What you will do

Work with large volumes of real-time data, implementing techniques for efficient rendering and smooth UX under high load.

Develop and maintain user-facing features using Next.js, ensuring performance, responsiveness, and scalability.

Transform detailed UI/UX mockups into performant, maintainable front-end components.

Collaborate closely with backend developers to ensure seamless, non-painful integration, following best practices for API design and data exchange.

Handle large data transfers through WebSockets and manage this information across the application with state managers.

 

Requirements

3+ years of experience in frontend development using modern frameworks such as Next.js.

Strong experience with state management.

Experienced in rendering and handling large volumes of realtime data.

Experience following structured development processes.

 

Work Approach

You care about the developer experience as much as the end-user experience.

You work well in cross-functional teams and enjoy turning complex ideas into clear, functional UI.

You find the balance between moving fast and building for the long term.

You think critically about build-vs-buy decisions balancing speed, cost and control. 

 

Bonus Points

Experience working on high-load systems with performance in mind.

Experience working in FinTech, WEB3 or other fast-paced, data-heavy domains.
