About Caravelo

At Caravelo, we are revolutionizing the travel industry with subscription-based solutions that help airlines and travel companies unlock new revenue streams while enhancing customer loyalty. Our SaaS platform enables seamless subscription management, dynamic pricing, and automation, helping airlines transition from traditional ticket sales to more sustainable, customer-centric models.

With a team of passionate innovators, engineers, and industry experts, we are building the future of travel technology. Headquartered in Barcelona, we operate globally, partnering with some of the world’s leading airlines to drive digital transformation and create frictionless, modern travel experiences.

The mission

We're looking for a Full Stack Developer who is analytical, results-driven, and grounded in Java backend development. Your center of gravity will be the backend: designing, building and maintaining the robust, scalable systems that power our SaaS platform in a high-transaction fintech and traveltech environment.
That said, this isn't a purely backend role.



You don't need to be a frontend expert, but you need to be sharp enough to pick up a ticket that touches the UI, lean on AI to vibe-code your way through the Vue side of it, and get it done properly rather than handing it off. Most of your work will be backend; some of it won't be, and you should be able to move between the two without friction.

Duties and responsibilities

Architecture and APIs
- Design, develop and maintain scalable backend systems using Java
- Build and evolve public and internal APIs, applying best practices in API security and data handling to meet stringent compliance requirements
- Apply Hexagonal Architecture principles to keep systems modular, maintainable and testable

Data and performance
- Work across relational and non-relational databases, including Couchbase, to design efficient, high-availability data models and queries for high-transaction workloads
- Proactively ident
