We’re looking for a Sr. Backend Engineer (Java/Kotlin) to join the Stellar team and help us keep that platform fast, stable, and secure underneath everything we build. You can work remote, hybrid, or fully onsite from our Brno or Prague offices.
The Stellar team is responsible for developer velocity and platform stability. We’re FE, BE, and QA engineers, working closely with the rest of the engineering teams to keep delivery pipelines fast and the platform architecture evolving cleanly. We collaborate to design solutions incrementally, and value learning, ownership, teamwork, and transparency.
Our tech stack is built for reliability, scalability, and speed of delivery across a distributed, containerized platform.
Our backend is developed in Kotlin with the Spring-Boot/Ktor frameworks and Python, backed by PostgreSQL and NoSQL as persistent storage. We lean on Pulsar for asynchronous communication, gRPC/REST for synchronous communication, and OpenAPI for our public API contracts.
We deploy on Kubernetes, provisioned with Terraform and Helm, and we own our GitHub Actions-based CI/CD pipelines end to end, from build to release.
