We are looking for a Senior Software Engineer to join our Data Ops team. In this role, you will lead the backend development of our internal applications, which directly impact Factorial’s sales and billing ecosystems. Your mission is to engineer highly resilient, scalable backend systems and robust cloud architectures that connect internal users, external clients, and financial workflows. You won't be managing data lakes or core data warehouses;
instead, you will own the full product lifecycle from architecture to deployment. If you think product‑first, value system stability, and want to leverage AI in your daily development workflow, this is for you!
What will you do? Own the backend architecture of internal sales, invoicing, and billing applications, ensuring maximum availability, security, and performance using a modern cloud stack.
Design and maintain robust backend workflows capable of handling critical financial data with high reliability and fault tolerance.
