Frontend Architect

We’re looking for a strong Frontend Engineer to build ultra-fast, reliable interfaces for a fintech platform serving 100M+ users. You will work on high-throughput, real-time data surfaces where performance, correctness, and security are critical.

Responsibilities

• Build low-latency, high-performance UIs with optimized rendering, virtualized lists, and minimal re-renders.
• Integrate real-time data using WebSockets / SSE / gRPC-web, handle diff streams, backpressure, and graceful degradation.
• Work in modular monorepos / micro-frontend architectures and set performance SLAs (LCP, FID, interaction latency).
• Implement strong frontend security : CSP, anti-tampering, secure storage, token handling, fraud-resistant flows.
• Add observability : client-side metrics, latency logs, RUM, tracing (Sentry / Datadog / OpenTelemetry).
• Collaborate with backend, platform, and security teams; write design docs and reusable libraries.
