• Your tasks and responsibilitiesDesign, develop, and maintain asynchronous, microservice-based backend systems, primarily in Python for external customer projects and in parallel in Java Spring Boot for our products
• Implement and optimize data processing and distribution pipelines that handle large volumes of orbital, telemetry, and mission data
• Design and maintain message-based communication structures between microservices (e.g., via RabbitMQ or comparable message brokers)
• Collaborate closely with space engineers and scientists to translate mission-related requirements into scalable, robust software solutions
• Share responsibility for the backend architecture across both tech stacks, with a focus on performance, fault tolerance, and maintainability
• Plan and document implementation steps, from system architecture through deployment in a cloud-native environment
• Ensure code quality, automated testing, and adherence to security and development standards
• Advance CI/CD pipelines, observability, and automation to support stable, continuous releases
• Analyze and resolve complex issues in distributed systems with a focus on efficiency and reliability
• Work within small, interdisciplinary teams, contributing your backend expertise to cross-functional projects
