  • Modern Tooling: Define and drive adoption of best practices in frontend frameworks, state management, testing, and performance monitoring.
  • Mentorship: Guide junior and mid-level frontend engineers. Promote best practices in accessibility, performance, and maintainability.
  • Quality & Security: Build secure, testable, and maintainable frontend components aligned with financial system requirements.
  • Collaboration: Partner with product managers, designers, and engineers across the company to deliver a seamless client and internal experience.

  • ≥ 3 years of experience building fintech, trading, or enterprise financial applications.
  • Deep expertise in modern frontend frameworks (React, TypeScript).
  • Strong understanding of state management (Redux, Recoil, Zustand, or similar) and real-time data handling (WebSockets, GraphQL subscriptions, streaming APIs).
  • Experience building enterprise-grade dashboards or trading/financial applications is highly preferred.
  • Strong grasp of performance optimization techniques (code splitting, caching, virtualization, memoization).
  • Familiarity with data visualization libraries , Recharts, Highcharts, etc.).
  • Knowledge of security and compliance considerations in frontend applications handling sensitive financial data.
What Will Help You Stand Out
  • Experience in real-time trading UIs (market data, order entry, risk dashboards).
  • Strong eye for design and collaboration with UI/UX teams.
  • Contributions to open-source frontend frameworks, tools, or libraries.
  • Familiarity with backend systems (pricing engines, OMS, risk management) to better integrate with the Core Trading stack.
  • Experience deploying frontend apps in cloud-native environments (AWS, Cloudflare, Kubernetes).
What We Offer
  • Competitive compensation, including equity.
  • Opportunity to own the full revamp of the OpenFX application, a critical client-facing product.
  • A highly collaborative and innovative work environment with peers from top financial and tech companies.
