About the role
Requirements:
- 5-7 years of experience building production web applications, with the majority of that depth on the frontend.
- A trading background: you've worked at a trading company, exchange, or brokerage and have built client-facing systems on a live trade or order path (e. g., CoinDCX, Groww, CoinSwitch Kuber, or similar).
- Deep expertise in TypeScript and React, and strong command of Redux or equivalent state management on non-trivial applications.
- Hands-on experience with server-side rendering and code splitting, and a clear sense of when each is worth the cost.
- Strong grasp of frontend architecture, component design, data fetching, error handling, and data synchronization between client and server.
- Experience building reliable UIs on top of asynchronous systems, where ordering isn't guaranteed, and failures are partial.
- Experience writing automated tests for the frontend and working with frontend test frameworks.
- Track record on frontend performance: you've diagnosed and fixed a slow production surface.
- Working backend proficiency: building CRUD and REST APIs, designing schemas and queries on PostgreSQL, and comfort in Next.js and Hono (or similar) server runtime. You should be able to own the backend of your own feature.
- Solid command of object-oriented programming principles and low-level design patterns.
- Comfort with abstract, ambiguous problems: you can turn a vague mandate into scoped, sequenced deliverables without waiting for someone to specify it for you.
- Hands-on and high agency. You find the important problem and go solve it rather than waiting to be assigned it.
- Heavy AI user. You use AI coding tools with real technique and get materially more done because of it.
- Data-driven and a clear written communicator; we are async-heavy and globally distributed.
What helps you stand out:
- Experience building real-time financial surfaces with live pricing, order books, or streaming quote updates.
- Experience with complex financial dashboards, reconciliation views, or transaction history at scale.
- Experience with FX, multi-currency systems, or cross-border payments.
- Experience with frontend testing, observability, and monitoring tooling.
- Experience building a design system or shared component library that other engineers actually used.
