More than 200 companies have implemented Invopop using only our API docs and support channels. As we move upmarket, larger enterprises need more hands-on technical support to design, build, and launch their integrations successfully. That’s why I’m looking for a Founding Solutions Engineer to help us build the post-sales function from scratch. You’ll work directly with engineering teams at some of the world’s fastest-moving tech companies to get them live across multiple countries. You’ll debug integrations, answer hard technical questions, design rollout plans, and help customers move from signed contract to production launch. You should be technical enough to read logs, reason about integration architecture, and write quick scripts when needed — but also pragmatic, organized, and comfortable working directly with customers. You’ll report directly to me initially and, over time, help shape how implementations and technical onboarding work at Invopop. ABOUT INVOPOP Invopop helps global companies like Qonto, Hyundai, and DeepL issue and receive invoices across more than 30 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 t
