About Us

We’re building the AI-powered planning platform that helps mid-market and scale-up companies plan smarter, faster, and with less waste. We’ve found strong product-market fit, have customers going live, and are scaling engineering to deliver even faster.

We’re looking for a Senior Full-Stack Engineer who loves working across the stack — building robust APIs and delightful UIs — and wants to ship end-to-end features that make an immediate impact.

Why This Role is Exciting

Pioneering Impact:
As our Senior Full-Stack Engineer, you’ll design and build the backbone of our product — from scalable APIs and optimization engines to the sleek UI our customers love. Your work will directly power the planning, forecasting, and decision-making workflows of our users.

Work across our modern stack — Nest.js, TypeScript, Postgres, React, Tailwind — and use best-in-class AI-assisted coding tools (Cursor, Claude, GPT-powered workflows).

Strategic Influence:
You’ll collaborate closely with founders, design, and product — shaping not just what we build but how we build it. You’ll influence architecture decisions for both frontend and backend, ensuring performance, scalability, and developer happiness.

Secured Funding & Vision:
Join a well-funded startup with strong product-market fit, committed to building category-defining supply chain software. Your code will be in the critical path of helping SMEs and mid-market companies plan smarter, faster, and more autonomously.

What You’ll Do

• Build full-stack features from React UI to Node.js APIs & Postgres schemas
• Work on data-rich workflows like demand forecasts, inventory views, and planning dashboards

• Strong skills in React + TypeScript, Node.js/Express, and Postgres/SQL
• Proven ability to work independently and deliver end-to-end features
• Eye for detail and obsessed with a well performing and beautiful frontend.
• Strong understanding of data modeling, API design, and debugging
• AI power-user: Use AI-assisted development tools (Cursor, Claude code) to support your work and move fast without sacrificing quality.

What We Offer

• Salary: € 85.000 / year
• Remote-Friendly: Work from anywhere, with regular team meet ups
• Velocity: Ship features used by real planners within days
