  • Contribute to the evolution of a product with 150,000+ users, growing at double-digit rates month over month.

What they’re looking for

  • Strong knowledge of AWS infrastructure and distributed systems.

  • Previous experience in startups or scaleups with growing products.

  • Ownership mindset and ability to bring technical vision.

  • Strong English communication skills.

What they offer

  • Competitive salary.

  • Real impact on a fintech product that helps thousands of people.

  • Open, collaborative, and highly international culture (team members from across Europe and LatAm).

  • Office in the heart of 22@ (Barcelona), just three blocks from the beach.

  • 2 days of teleworking per week.

  • Dynamic environment with afterworks, team events, and two company-wide gatherings per year.
