What We're Looking For
We are looking for a Senior Back-end Developer (Java) who is dreaming of developing ambitious tech products. You’ll join our Payments team, a core part of our tech organization that’s building a modern, internal payments platform from the ground up. Our mission is to streamline and future-proof payment operations across the entire business. We're not just maintaining systems—we’re rethinking how payments should work in fast-scaling products.
The team is a highly collaborative, cross-functional group with deep expertise in infrastructure, databases, distributed systems, and back-end engineering. We value autonomy, ownership, and knowledge-sharing, and we’re always looking for new ideas to make our systems smarter, faster, and more secure. You’ll have the opportunity to work on technically rich projects that have real, measurable business impact—and have a lot of fun along the way.

- Design and implement robust systems: Translate both functional and non-functional requirements into scalable, reliable, and maintainable software. Your code will directly shape user experiences and system integrity.
- Build and operate microservices: Develop, deploy, and maintain high-performance microservices using Spring Boot. Own your services end-to-end—from design and implementation to deployment and ongoing support.
- Operate in cloud-native environments: Manage deployments and configurations across various Kubernetes clusters, ensuring smooth rollouts and minimal downtime in production and staging environments.
- Champion system excellence: Take responsibility for the performance, scalability, security, and data consistency of the systems your team owns. Proactively identify bottlenecks and propose architectural improvements.
- Drive engineering best practices: Promote clean code, test automation, continuous integration, and DevOps principles. Help elevate the engineering culture through thoughtful code reviews, tech talks, and collaboration.
- Mentor & lead by example: Provide guidance to team members, l
