Job Description
We are looking for a Senior Frontend Developer to build the client-side of a new P2P payment platform, including the trading board / order book, personal cabinet, deal interface, and real-time chat. You will work on data-intensive, real-time interfaces where performance, reliability, and security are critical, and play a key role in shaping the frontend architecture from an early stage.
About the Client
Our client is building a new P2P payment system from the ground up — a fintech product enabling secure, fast, and scalable peer-to-peer transactions. The company is focused on creating reliable payment infrastructure, combining modern architecture with strong transactional guarantees to serve users at scale.
What You Will Do
-
Develop the client-side of the platform: order book / trading board, personal cabinet, deal flow interface, and real-time chat.
-
Build and maintain real-time data updates using WebSockets / gRPC-Web.
-
Design and manage complex application state using Zustand / Redux Toolkit.
-
Build reusable, well-structured components and maintain a scalable frontend architecture using React and Next.js.
-
Ensure high performance and responsiveness of data-heavy, real-time UI (order books, live updates, notifications).
-
Implement client-side security best practices (XSS/CSRF protection, secure token storage and handling).
-
Collaborate closely with backend engineers to define API contracts and real-time data flows.
-
Participate in code reviews, contribute to frontend architecture decisions, and help establish best practices across the team.
-
Write clean, well-typed, maintainable TypeScript code.
-
Take ownership of frontend features from design through production, ensuring quality and reliability.
What We Are Looking For
-
Strong hands-on experience with TypeScript, React, and Next.js.
-
Experience with WebSockets / gRPC-Web for real-time data updates.
-
Solid experience managing complex application state (Zustand, Redux Toolkit).
-
Understanding of client-side security fundamentals (XSS, CSRF, secure token storage).
-
Experience building data-intensive, real-time interfaces (trading platforms, dashboards, chat applications, or similar) is a strong plus.
-
Good understanding of performance optimization techniques for React applications.
-
Ability to collaborate closely with backend teams and contribute to API design discussions.
-
Strong attention to detail and a product-oriented mindset.
-
Upper-Intermediate English level or higher (written and spoken) is a plus.
-
Prior experience in fintech, trading platforms, or high-load transactional products is a plus.
What You Can Expect
-
Opportunity to build the frontend of a payment platform from the ground up and shape its architecture.
-
Career growth opportunities with the potential to grow into a Lead Frontend Developer role.
-
Close collaboration with backend and product teams, with real influence over key technical and UX decisions.
