About this role
Suppli is redefining the user experience for the distribution industry, seeking a Frontend / Fullstack Engineer to architect and build frontend systems. The role involves creating intuitive interfaces that integrate with complex ERP systems and leveraging cutting-edge LLM technology.
Responsibilities:
- High-volume payment UIs: Real-time dashboards, clear status updates, comprehensive histories, and streamlined, secure payment flows
- LLM-powered experiences: Interfaces for automated credit decisions, intelligent customer comms, document processing, and workflow assist
- Financial workflows: Dynamic forms, validations, and guided, multi-step flows that make complex tasks simple and fast
- Data-rich visualization: Interactive tables, charts, and insights for millions of financial records with snappy performance
- Front-end platform: Design system components, accessibility, perf budgets, error handling, and observability across the UI
Requirements:
- 4+ years of frontend experience shipping production web apps with React (modern hooks & patterns)
- Strong TypeScript fundamentals and a track record of building robust, type-safe UI code
- Deep experience integrating APIs (GraphQL preferred; REST is a plus), including pagination, caching, and optimistic updates
- Mastery of core web tech: JavaScript, HTML, CSS — and performance techniques (memoization, virtualization, code splitting)
- Testing discipline: Comfortable with unit, integration, and end-to-end testing (Jest, Vitest, Cypress)
- Care for UX & accessibility: Semantic HTML, ARIA, keyboard-first flows, and fast feedback cycles with designers and users
- Experience with Next.js or modern React frameworks (routing, SSR/SSG, edge rendering)
- Familiarity with state management (Redux/RTK or similar), and form libraries (Final-Form)
- Styling systems experience: Material UI, BlueprintJS, Tailwind CSS, and component-level performance optimization
- Frontend observability: Feature flags, analytics, error tracking, and perf monitoring (Sentry, RUM tools)
- Security-savvy UI: CSP, secure token handling, least-privilege mindset, and fintech/payment UI constraints
