About the company

Satispay is an Italian fintech that makes financial services simple and accessible to over 6.5 million users. It started with payments and has expanded into company benefits, investing and cards, with the goal of building the most loved financial platform in the world. The engineering team runs on cloud infrastructure with volumes growing every day, and values ownership and problem solving. Positions are open across several product domains (Core, Business, Consumer), and Satispay assigns the domain at the end of the process.

What you will do

• Design and evolve the most sensitive systems of the payment platform, owning them from design to production
• Contribute to services for bank integrations, risk and fraud prevention, where performance and reliability matter
• Lead technical analyses that span multiple services and produce high-quality documentation (Smart Papers) for stakeholders

You have already taken a complex design to production with ownership, and you can explain the trade-offs and the problems you met along the way.
