TL;DR We’re looking for a Senior Full Stack Engineer (React/Node.js) to build the engine behind how Europe’s top companies discover and implement startup innovation. You’ll take ownership of complex systems, work fast without breaking things, and write code that drives real business outcomes — not just sprints. What we´re looking for You build like a founder. You don’t just “do tickets.” You build features with intention, speed, and a strong sense of ownership. You take end-to-end responsibility. From concept to commit to post-release tracking — if it’s yours, you drive it forward. You are a pro - your code shows it. You know the cost of technical debt. You write clean, maintainable code — and know when to break things to move faster. You value fast feedback loops. Playwright on the frontend, Jest on the backend. You don’t wait for QA to catch issues. You think in systems. You’re not afraid of shaping architecture and improving how the machine runs — not just what it does. You communicate clearly. With engineers, with ops, with product. You make things understandable — and decisions traceable. Your toolkit: React, TypeScript, Apollo GraphQL Node.js, TypeScript, Prisma, PostgreSQL, Vector databases 5 years of experience in building, maintaining, and shipping real applications Location: Berlin is preferred. Remote is possible — but we value real face time. Don’t check every box? Apply anyway. We value builders over buzzwords. What you`ll do We’re building the GlassDollar OS — a venture clienting platform that helps corporations find, test, and implement startup tech at scale. Your job? Build the thing that makes all of that possible. What that looks like: Designing and shipping full-stack features that matter Building tools that make our startup sourcing workflow smarter and faster Creating systems that scale — across industries, clients, and use cases Turning business needs into clean, functional code Working closely with product and ops to kill inefficiencies Writing tests, automating the boring stuff, and focusing on the impactful Measuring what you ship — and learning from how it performs We’re a small team of PROs — no micro-managers, no bloated processes, no dead weight. If you’re the kind of engineer who thrives on responsibility, speed, and clarity — we should talk. How we hire Straightforward. Respectful of your time. No mystery steps. Intro call – quick chat to see if there’s a match Tech interview – let’s talk through your thinking and experience Offer – if it clicks, we don’t wait around
