easybill GmbH is a company that provides cloud-based invoicing software solutions, allowing users to create electronic invoices, manage billing, and automate sales processes. Their platform integrates with various popular marketplaces and accounting systems, ensuring compliance with German GoBD regulations and upcoming EU e-invoicing mandates. They cater to a wide range of clients including freelancers, small businesses, and online retailers, offering efficiency and ease in handling billing and document management.

📋 Description

• You develop and improve our e‑commerce application easybill Connect using Ruby on Rails • You take ownership of complete features and projects — from technical design through implementation to stable operation • You work on scalable backend solutions, robust integrations and high‑performance processes for marketplaces, shop systems, shipping and e‑commerce APIs • When required, you also contribute to the frontend with TypeScript and React and focus your efforts where they have the greatest impact • You support data migrations, refactorings and technical modernizations with a clear focus on stability, maintainability and quality • You analyze defects systematically, get to the root cause and ensure problems are resolved sustainably • You use AI tools such as Claude Code as a natural part of your development workflow to iterate faster, better review code, understand context and increase productivity • You contribute your own ideas, challenge existing solutions constructively and help continuously improve our engineering processes • You collaborate closely with Product, UX, Support and other engineering teams when it makes sense for the project

🎯 Requirements

• You have extensive experience in software development and understand how to build, operate and evolve modern web applications reliably • You have strong knowledge in at least one relevant backend stack — ideally Ruby on Rails; alternatively, you can quickly and methodically get up to speed • You think not only in code but in terms of products, processes, users and long‑term viable solutions • You work independently, proactively and with high standards for quality • You have experience structuring technical topics, preparing decisions and driving projects forward autonomously • You use AI tools such as Claude Code, ChatGPT or similar solutions as a natural part of your workflow — not because they are trendy, but because you see a real lever for speed, quality and learning • You enjoy trying out new tools, working methods and automation opportunities and integrating them sensibly into your daily work • You communicate clearly, reliably and on an equal footing • You speak fluent German and good English

🏖️ Benefits

• 30 days vacation • Workation: take advantage of our workation options (villa in Mallorca) • Training: €1,500/year budget for your professional and personal development • Hackathons: turn your own ideas into real features • Ownership from day one: responsibility instead of busywork • JobRad: lease your preferred bike or e‑bike on attractive terms • Givve Card: monthly tax‑free benefits for your personal needs
