Senior Product Engineer

About ProfitPath

ProfitPath is the all-in-one sourcing platform for Amazon sellers. We help thousands of sellers across Europe find profitable products — through our supplier search, price alerts, competitor analysis, and wholesale scanner. Built by FourByte GmbH, we're a small, ambitious team shaping the future of online arbitrage.

The Role

You own features end to end. Database schema, API, UI — all yours. You work across the full stack: data-intensive interfaces in Next.js on one side, robust APIs and services in Node.js on the other. You collaborate directly with design and product, and have real influence over technical direction and user experience. No feature goes through three approval rounds — you have a say, you build, you ship.

What We Expect

• 5+ years of full-stack web development
• TypeScript, React, and Node.js — your daily toolkit
• RESTful APIs and PostgreSQL — schema design, query optimization
• You drive projects from idea to production independently
• Strong communication — you can explain technical decisions to non-technical stakeholders

Nice to Have

• Next.js App Router, Server Components, React Server Components
• Experience with e-commerce platforms, Amazon SP-API, or marketplace data
• Data pipelines, web scraping, or ETL processes at scale
• Open-source contributions or a strong technical blog/portfolio

Mindset

• You don't just want to write code — you want to shape the product.
• You actively use AI tools and continuously improve your workflows.
• You simplify instead of adding complexity.
• You learn on your own initiative. New tools, new patterns, new domain knowledge.

What We Offer

• Brand-new cozy office in the heart of Sülz, Cologne
• Direct collaboration with the founders — short feedback loops, fast decisions
• Real ownership instead of micromanagement
• Direct impact on a product used by thousands of sellers every day
• A team that treats AI as a core part of daily work
