About the role
You'll own end-to-end features for a data-intensive platform handling 100k+ rows with instant search, real-time updates, and complex filtering. You'll work across the stack — from database queries and API design to frontend performance — with a strong focus on backend depth and execution speed.
What you'll do
* Build and optimize data-heavy features using React, Node.js, PostgreSQL, and Elasticsearch — filtering, faceting, saved views, real-time updates. * Design efficient APIs and database queries (indexes, pagination, cursor-based, aggregation) to handle large-scale datasets. * Implement optimistic updates, conflict resolution, and retry queues for smooth user interactions. * Own features from requirement to production — making smart trade-offs between speed, quality, and technical debt. * Use AI tools (Cursor, Claude, Copilot) daily to accelerate development. * Continuously monitor and improve performance (query latency, rendering, scrolling FPS).
You may be a fit if you have
* 5+ years of full-stack experience with strong backend focus (Node.js, PostgreSQL, Elasticsearch). * Solid React/TypeScript skills (frontend is still important, but backend depth matters more). * Experience building products or features end-to-end — you've shipped things people use. * You use AI daily (Cursor, Claude, Copilot) to write, debug, and refactor code. * Founder mindset — you've built side projects, MVPs, or your own products. You take ownership, move fast, and don't wait for perfect requirements. * You understand database performance (indexes, query optimization, pagination strategies) and search (Elasticsearch).
Nice to have
* Experience with real-time collaboration (WebSockets, Liveblocks). * Background in startups or building products from scratch. * Open-source contributions or public side projects. * Familiarity with feature flags, analytics (PostHog/Amplitude), and error monitoring.
We offer
* Remote within Europe. * Small, autonomous team — no micromanagement. * Heavy focus on execution speed and impact. * Competitive B2B compensation.
