Try Premium for PKR0 Meet the hiring team Alina Nicole Trombley Alina Nicole Trombley 3rd Chief Compliance Officer Job poster Message About the job 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. Ability to propose how the platform should look and feel for professional-grade trading (information architecture, workflows, responsiveness, error handling). 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). Experience with design systems and accessibility at scale. What Success Looks Like A stable, fast, intuitive trading UI that performs under peak load, handles degraded networks gracefully, and supports compliance/audit requirements.
