We are looking for a Process Automation Engineer (Java / Spring Boot) who wants to build real systems - but not spend ten hours a day writing the same CRUD boilerplate. In this role the architecture is the process: you model executable workflows in BPMN 2.0, CMMN, and DMN, run them on a process engine such as Camunda, Flowable, or UiPath Maestro, and back them with clean, well-tested Java and Spring Boot services.

You take ownership of delivering the solution by implementing the process models and the service tasks behind them, wiring them into the existing IT landscape through REST APIs and message-based integrations, and tuning the engine for performance and scale in production.

Working closely with business and IT stakeholders, you turn messy real-world processes into robust, executable models that actually run. Your work spans both classic process orchestration on a workflow engine and the introduction of modern hyperautomation and agentic automation concepts. You have a direct hand in how we build automation - choosing engines and patterns, defining reusable building blocks, and keeping the platform clean as it grows to meet demanding enterprise needs.

As part of the adesso Business Automation Line of Business, you join a collaborative, international, and multidisciplinary engineering team. You’ll work on innovative projects that blend hands‑on engineering, process modelling, and orchestration frameworks - enabling organizations to achieve new levels of efficiency and agility through automation.

• You hold a successfully completed degree in Computer Science, Business Informatics, Data Science, or a comparable field with relevant focus. Or completed an apprenticeship in IT sector.

• Fluency in English and C1 proficiency in German.

• at least 3+ years related professional experience.

• Proficiency in Java, particularly with Spring Boot.
• Hands‑on experience with a workflow / process engine such as Camunda, Flowable, or UiPath Maestro - building and running executable processes, not just diagrams.
• Practical command of the standard modelling notations - BPMN 2.0, CMMN 1.1, and DMN 1.3.
• Comfortable orchestrating long‑running processes: service tasks, message and signal events, timers, and decision tables.
• Experience with JUnit testing and mocking frameworks.
• Strong knowledge of DBMS, SQL, JPA, ORM.
• Skilled in build automation using Maven or Gradle.
• Proficient with version control systems (e.g., Git).
