Full Stack Developer (Europe, Remote)

About the job Full Stack Developer (Europe, Remote)

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.
