Job Title: Frontend / Fullstack Engineer Company Name: Suppli Job Url: https://app.dover.com/apply/suppli/fb4404da-aaff-4f0a-bd11-ef7b37fc1b06?rs=42706078&jr_id=698a619cc5761b521a998dac Job Description: About the Role Join Suppli as a Frontend / Fullstack Engineer and play a pivotal role in redefining the user experience for the >$1tn distribution industry. As a key member of our team, you will architect and build the frontend systems that empower distributors to visualize and manage millions of dollars in daily transactions. You'll create seamless, intuitive interfaces that integrate with complex ERP systems and leverage cutting-edge LLM technology to transform how our users manage their revenue cycles. You’ll join a small team of A+ players where everyone acts as an individual contributor while actively supporting each other through pair programming and collaborative problem-solving. You’ll work closely with our founder-led team who previously operated a distribution business and understand the real-world problems we’re solving. Who Thrives Here (read this first — it saves everyone time) AI-Native: You already use Cursor, Claude, GitHub Copilot, or similar every single day. You treat AI as a pair programmer, not a toy or a threat. Product-minded: You obsess over the “why,” dig into usage data or talk to customers, and measure success in revenue and user love — not story points. Ownership > tasks: You hate being blocked. When requirements are fuzzy, you prototype, pair, reach out directly, or just ship a pragmatic solution. Builder mentality: Strong opinions, weakly held. You default to the simplest thing that works (often with AI help), then iterate fast. What You’ll Own 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. Must-Have 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. Bonus Points 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. Tech Stack (today — evolves fast) Frontend: React (latest), TypeScript, Redux, Final-Form, GraphQL UI & Styling: Material UI, BlueprintJS, Tailwind CSS Backend: Ruby on Rails (latest), PostgreSQL, Sidekiq Infrastructure: AWS, Docker, automated deployment pipelines Integrations: RESTful APIs, webhooks, third-party financial services AI/ML: LLM integration for document processing and automation Security: Bank-grade encryption, secure data handling Engineering Culture True end-to-end ownership — no PMs writing pixel-perfect specs. We pair program (human + AI), ship daily, write tests that matter, and refactor mercilessly. AI tools are first-class citizens here: we expect you to 10× your output with them and help us push the boundaries of what’s possible in fintech automation.
