Full Stack Developer - UX (Europe)

Remote, South Africa

You'll own the UX and much of the application logic for a highly interactive, spreadsheet-style table. Your north star is speed, polish, and correctness the experience should feel as smooth as the best modern tools (Notion, Google Sheets, Clay).

What you'll do

Build a virtualized, configurable table that performs smoothly at scale (50k100k+ rows) with features like resize/reorder, hide/show, freeze, multi-select, bulk edit, and inline validation.

Deliver a rich filter and sort experience: multi-field, AND/OR groups, saved views, quick search, and faceting powered by a search backend.

Implement inline editing with optimistic updates, conflict resolution, and resilient fallbacks (e.g., retry queues).

Create advanced column operations: duplicate/rename, derived or computed fields, enrichment triggers per row/selection.

Maintain high UX standards, including empty/error/loading states, responsive layouts, and internationalization readiness.

Continuously instrument and optimize performance (virtual scrolling, memoization, batching) to meet TTI/LCP budgets, p95 latency goals, and fps targets while scrolling.

You may be a fit if you have
