We are building a Java team in our Krakow office at Keepit, and we're looking for a Senior Java Engineer to help shape it from the ground up. You will work on our cloud-to-cloud backup platform: a distributed, high-availability system that protects the critical SaaS data of organizations worldwide. This role involves owning complex components and features end-to-end, while also driving key architectural decisions for greenfield Java backend projects.

You will:
Lead technical design and architecture for features and services, ensuring scalability and maintainability
Participate in all phases of the software development lifecycle
Collaborate with Product, QA, Support, and Operations teams to resolve issues and deliver improvements
Maintain high code quality by clear documentation, thorough code review, and architectural improvements
Ensure system reliability, including error handling, observability, and scalability
Mentor and grow other developers; be the go-to technical authority on the team
Must-haves:
5+ years of backend Java development experience
Solid experience with the Spring Boot ecosystem, RESTful API design, and modern service-oriented architecture
Experience working with KeyCloak, and good understanding of Authentication and authorization systems
Solid understanding of SQL and working with relational databases
Experience with docker and containerized solutions
Familiarity with event-driven architecture (e.g. Kafka, RabbitMQ)
Experience with CI/CD pipelines and modern DevOps practices
Strong initiative and a proactive mindset, with a willingness to share knowledge in a collaborative environment
Ability to work independently and take full ownership of technical decisions
