Tech Lead - Experience & Front-End

The Tech Lead — Experience & Front-End is the senior front-end leader for an AI-native retail decisioning platform — accountable for multiple distinct user surfaces (workbenches, supplier portal web and mobile, executive dashboard, internal agent builder workspace, governance console, AI copilot) used by diverse personas across merchandising, supply chain, finance, supplier collaboration, and executive insights. The role owns front-end architecture, design system, accessibility, performance, and multi-surface consistency. Remote candidates outside of Thailand are welcome to apply. Key Responsibilities: Own the front-end reference architecture — framework choice (React / Next.js or comparable), state management, API layer, design system, observability — and Architecture Decision Records for surface-level decisions. Co-author and maintain the platform design system and component library; ensure WCAG 2.2 AA accessibility is embedded in every component. Lead build of the internal agent builder workspace for data-scientist / ML-engineer users — build / eval / deploy agents from a template. Lead build of the Supplier Portal (web + mobile) for external suppliers — onboarding, purchase order, invoice, trade-deal flows; mobile parity within one release. Lead build of executive dashboards, workbench surfaces (merchandiser, buyer, planner, finance), the governance console (multi-module: trust gate, cost meter, audit log, AI trust dashboard), and the AI copilot. Own client-side performance SLOs (LCP, INP, CLS per surface) and instrument client-side observability (errors, performance, usage). Lead 1–2 senior front-end engineers and 1 UX / Designer; mentor on front-end engineering excellence (performance, accessibility, design-system discipline). Drive persona usability testing — pre-launch and post-launch per surface. Bachelor's or Master's degree in Computer Science, Design, or a related discipline. 8+ years front-end engineering with 3+ years in a Tech Lead / Staff role. Production multi-surface platforms — has led 3+ distinct front-end surfaces. Strong React / Next.js (or comparable) at staff level; TypeScript at production rigor. Design system / component library ownership at scale. Accessibility (WCAG 2.2 AA) — production CI gates, not just lip service. Mobile experience — at least one production mobile surface (React Native, web mobile, or native). Performance discipline — LCP / INP / CLS / bundle budgets; cross-team partnership with UX, back-end, product, security. Preferred Qualifications: AI / Copilot surface experience (Cursor, ChatGPT, Claude, GitHub Copilot, comparable). Builder / low-code-style surface experience (Retool, Toolpad, comparable). Governance / audit dashboard experience (explainability surfaces). Open-source contributions to design-system or accessibility tooling.
