Responsibilities

End‑to‑End Delivery: Own major web features—from technical discovery and architecture to implementation, testing, deployment, and post‑release iteration

Frontend Engineering: Build performant, accessible React/Next.js + TypeScript UIs; apply SSR/SSG/ISR pragmatically; instrument analytics and A/B testing; optimize H5/mobile performance and Core Web Vitals; implement real‑time charting/visualizations for market data (e.g., TradingView Lightweight Charts) including live updates

Market Data & Order Books: Design and implement reliable REST/GraphQL + WebSocket APIs and BFF services for tickers, trades, and order‑book depth; maintain local order‑book snapshots with delta streams, sequence handling, and resync strategies aligned with major exchange guidance

Security & Authentication: Implement robust auth flows (OAuth2/OIDC), phishing‑resistant MFA (WebAuthn/FIDO2) where appropriate, secrets/KMS, fine‑grained RBAC; enforce least‑privilege for third‑party data/exchange APIs

Wallet & Web3: Support EVM wallet interoperability via EIP‑1193 provider interfaces and WalletConnect where needed for token workflows; design safe isolation boundaries between custody/wallet flows and web apps

Streaming & Scheduling: Build and operate time‑series/streaming pipelines (WebSocket/SSE/queues) for live charts, index/weight computations, and scheduled jobs; design backpressure, retries, and durable audit trails

Reliability & Observability: Drive performance, security, and reliability at scale (caching/CDN, rate limiting, logging/metrics/tracing, incident response); ensure auditability/traceability of financial computations end‑to‑end

Collaboration: Work closely with Product/Design/Compliance to translate requirements into high‑quality, incremental releases; uphold i18n (English/Chinese) and accessibility standards
