Role Summary
We are hiring a Senior Frontend Engineer / Frontend Architect to lead the design and implementation of our production-grade trading UX for a Liquidity Trading ATS platform with crypto trading capabilities. You will own the frontend architecture, performance, reliability, and user experience for real-time trading workflows, market data, order entry, blotters, positions, risk views, and onboarding flows working closely with backend, product, compliance, and security teams.
Responsibilities
-Architect and deliver high-performance trading UIs (real-time quotes, order tickets, depth/market data, charts, blotters, positions, balances).
-Build scalable frontend patterns for low-latency streaming data (WebSockets/SSE), state management, caching, and optimistic UI.
-Define UI standards for trader-grade usability: keyboard-first workflows, accessibility, error states, resilience, and audit-friendly interactions.
-Partner with backend teams to define API contracts (REST/gRPC) and real-time event schemas (Kafka/NATS/etc.).
-Implement frontend observability: performance metrics, error tracking, user journeys, and uptime dashboards.
-Enforce secure coding practices.
-Mentor engineers; drive code quality, reviews, and CI/CD.
Required Qualifications
-8+ years frontend engineering experience with at least 2+ years in an architecture/tech lead role.
-Proven experience building trading or market-data heavy web and mobile applications (equities, options, FX, crypto, or ATS/exchange UIs).
-Expert in modern web frameworks (e.g., React/TypeScript preferred) and component architecture.
-Hands-on with real-time data patterns: WebSockets, event-driven UI updates, backpressure handling.
-Strong understanding of frontend performance tuning (render profiling, virtualization, caching, bundle optimization).
-Experience working in regulated environments (FINRA/SEC/CFTC, SOC2/ISO controls) and building audit-friendly UX.
Domain Requirements (Strongly Preferred)
-Prior work at or with platforms similar to TD Ameritrade, Robinhood, Coinbase, or comparable brokerages/exchanges/ATS providers.
-Strong understanding of trading domain concepts: orders, fills, cancels, TIF, order types, positions, margin, fees, and corporate actions.
-Familiarity with broker-dealer (BD) and transfer agent (TA) operational flows as they relate to customer onboarding, account funding, trade lifecycle, statements, and reconciliation.
Nice-to-Have
-Experience with security controls for fintech apps: device binding, MFA, session hardening.
-Experience building charting/analytics UIs (TradingView integrations or custom charting).
-Knowledge of blockchain concepts relevant to trading/settlement (wallets, signing flows, chain events).
