Tasks
We at etalytics are currently looking for a Senior Backend Software Developer (m/f/d) for our office in Darmstadt, Germany. You will join our backend team, which builds our etaONE® platform for energy intelligence based on a modern microservice tech stack. You will implement and maintain features from the Rest API down to the persistence layer. We value a modern, clean and testable software design, and are looking for candidates who share these values.

WHAT YOU CAN EXPECT:

• Design and develop backend features using modern frameworks and tools, such as Spring Boot (Java/Kotlin/Graal), Hibernate, Git, Gradle, PostgreSQL, and MQTT.
• Contribute to the ongoing development of our cloud-native microservice architecture using innovative technologies like Spring, Docker/Kubernetes, CI/CD pipelines, and async pub/sub.
• Provide technical and functional support in the development of new product and solution ideas, proactively contributing creative suggestions, solution approaches, and technologies to the development process.
• Maintain high code quality standards through test automation with JUnit, Mockito, and MockK, test-driven development, and static code analysis.
• Collaborate closely with other developers and specialist departments throughout the software lifecycle - from planning to development and rollout.
• Participate in an active developer community, engaging in knowledge exchange with colleagues to stay up to date in your field.

Requirements

• Experience: 5+ years in software development with Spring Boot or comparable roles, with a proven track record of leading complex data projects and initiatives.
• Technical Expertise: Proficiency in JVM languages (Kotlin/Java), SQL, TDD, and data modeling, with a solid understanding of REST APIs.
• Software Engineering Skills: Strong foundation in software engineering principles, including CI/CD pipelines, version control (e.g., Git), Java/Kotlin, automated testing (e.g., JUnit and Mockito), and data management with relational databases (e.g., PostgreSQL).
• Infrastructure Tools Proficiency: Hands-on experience with tools like Docker and Shell. Familiarity with additional tools and platforms (e.g., Kubernetes) is a plus.
• Problem-Solving: Excellent analytical and problem-solving skills, with the ability to diagnose and resolve complex technical issues independently.
• Leadership: Demonstrated ability to mentor and lead junior engineers, fostering a collaborative and high-performance team environment.
• Communication: Strong communication skills, with the ability to convey complex technical concepts clearly to both technical and non-technical stakeholders.
• Languages: Good written and spoken German and English skills complete your profile.
