Senior Software Engineer (Payments and Banking) en Madrid, España

Embat is one of the fastest-growing FinTech startups in Europe, founded in 2021 to transform how mid-market and enterprise companies manage their finances in real time.

At the core of Embat lies a powerful financial platform that goes far beyond visibility: Payments and Banking are becoming a central pillar of our product . Over the last months, transaction volumes have doubled, and we are scaling rapidly to support complex, high-volume payment flows for multinational customers operating across multiple countries and currencies.

Our mission is to build globally scalable, secure, and resilient financial infrastructure that enables companies to move money with confidence: from local payment rails to international transfers, from real-time balances to reliable ledgers. All of this, delivered as a modern SaaS product that replaces manual, error-prone processes and unlocks real-time decision-making.

We are a team of 120+ people, backed by leading international investors. In February 2024, we closed a €15M Series A led by Creandum, alongside Samaipata, 4Founders Capital, and VentureFriends. Our ambition is clear: build a global FinTech category leader and a place where exceptional engineers do the best work of their careers .
