Software Engineer | AI x Fintech | Founding Engineering Team (España)

About the opportunity

• This is not a typical engineering hire. This is a founding seat inside the Barcelona office of a fast growing, well-funded company building the financial infrastructure layer for AI agents.
• You will work alongside an experienced founding team with strong backing, high technical standards, and a product already gaining traction.
• This is the kind of role where ownership is real: architecture decisions, product direction, engineering practices, and long-term impact.

The team behind

You’ll work alongside operators who have already built category-defining companies:

• CEO previously scaled a company to $250M ARR and a $4.4B valuation
• CPO previously founded and sold a billing infrastructure company to Salesforce
• Early engineers and advisors from Stripe, Meta & Palantir
• The Barcelona office will become the company’s founding engineering hub in Europe.
