- 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
- 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 identify and resolve performance bottlenecks, using observability tools like Datadog to monitor system performance
- Quality and reliability
- Ensure high-quality code through rigorous unit, integration and automated testing, and lead by example in code reviews
- Implement observability practices (metrics, logging, tracing) to monitor system health and catch issues before they become incidents
- Proactively identify technical debt and drive the improvements needed to keep the codebase clean
- Frontend collaboration
- Pick up frontend work in Vue.js when a feature calls for it, leaning on AI to vibe-code the UI side and working end-to-end rather than only on the backend half of a ticket
- Collaborate with the frontend team to keep the product con
