Your responsibilities

• Designing and building robust, production-grade Java APIs and backend services using Java 25 and Spring.
• Implementing and maintaining workflow orchestration with Temporal.io for reliable, long-running process management.
• Working with Azure services - App Service, Key Vault, Graph API, networking, and DevOps Pipelines - to deliver and operate cloud-native solutions.
• Containerizing and managing services with Docker and Docker Compose.
• Designing and working with MSSQL databases, ensuring data integrity and query efficiency.
• Implementing secure authentication and authorization using OAuth2.
• Writing meaningful, well-structured tests using Spock and Groovy.
• Making deliberate, targeted code changes - respecting existing conventions and minimizing unintended side effects.
• Communicating clearly with both technical peers and client stakeholders, contributing to shared understanding of goals and constraints.
• Leveraging AI tools in day-to-day work to enhance productivity and output quality.

Our requirements

• 5+ years of commercial experience as a Java engineer with proven depth in backend system design.
• Strong proficiency in Java (ideally up to date with recent versions) and Spring ecosystem.
• Hands-on experience with Temporal.io or comparable workflow orchestration frameworks.
• Solid Azure experience - App Service, Key Vault, Graph API, networking, and DevOps Pipelines.
• Practical knowledge of Docker and Docker Compose for containerized development and deployment.
• Strong SQL and MSSQL skills - comfortable with schema design, querying, and optimization.
• Solid understanding of OAuth2 and modern authentication/authorization patterns.
• Experience with Spock/Groovy for testing, or strong willingness to adopt it.
• Simplicity-first mindset - you design for clarity, not cleverness, and your default is to do less, better.
• Goal-driven execution - you understand the why behind tasks and make decisions that serve the outcome, not just the ticket.
• Surgical approach to changes - you respect conventions, assess impact before acting, and avoid unnecessary scope creep.
• Strong communication skills - able to engage with technical peers and non-technical stakeholders with equal clarity.
• Fluent English, able to collaborate effectively across international teams.

Optional

• Familiarity with Databricks and Unity Catalog concepts.
• Experience with Terraform or infrastructure-as-code practices.
