About this role

Staff Backend Product Engineer Madrid | Hybrid | Remote TL;DR - We're a global e-invoicing platform operating in 25+ countries. - Revenue grew 10x last year, and we plan to 3x in 2026. - Role: own integrations end-to-end, research, define, build, ship, and iterate with customers. - Looking for: 10+ years of backend experience, strong product judgment, fluent English, builder mentality, comfort with ambiguity, and complex domains. - Compensation: €90k-€140k base + Stock Options. - Location: Madrid (at least 3-4 days/month in our office, travel expenses paid). ⸻ Hi there 👋🏼, I'm Juan, the CEO of Invopop. We help companies like Fever, DeepL, Booksy, and SumUp issue and receive invoices that comply with local requirements across 25+ countries. We're looking for a Staff Backend Product Engineer to join our team. If you enjoy solving hard problems with elegant software, owning your roadmap, and helping shape what we build (and how), this role could be a great fit. ABOUT INVOPOP Invopop helps global companies like SumUp, Fever, and DeepL issue and receive invoices across more than 25 countries through a single API. In the next five years, more than 40 countries, including the entire EU, will mandate that businesses send invoices electronically (in XML format) and report them in real-time to tax authorities. This reduces fraud and enables companies to automate invoice processing instead of relying on OCR. There's only one catch: each country has defined unique standards, forcing global companies to build dozens of local integrations-or integrate once with Invopop.
