Software Engineer Java or C++ (f/m/d)

Your area of work:

We are looking for an experienced Software Engineer to join the CBL Connectivity & Data development team (HUB) to work on a JMS middleware application. The application is based on Java (JDK21+) and C++, in-house developed, and deployed partially as a standalone Java application and partially on the OpenShift platform. For persistence, Oracle RDBMS, IBM MQ, and Apache Kafka are used. The application consists of separate micro-services which communicate over JMS with each other as well as with the rest of the world. We use GitHub, JIRA, Gradle, Jenkins, Sonar, JUnit, HPFortify, and — last but not least — AI tools including the most advanced models from Anthropic, OpenAI and Google.

We're looking for someone who treats software delivery as more than writing code — analyzing problems deeply, designing secure solutions, and owning outcomes through to a stable production result.

Your responsibilities:

• Work on a highly critical part of connectivity infrastructure
• Analyze and clarify business requirements, identifying gaps, risks, and edge cases
• Design interfaces and solutions for internal and external systems, weighing trade-offs and long-term impact
• Communicate scope, timeline, and progress proactively; present and refine solution proposals with the team
• Apply secure-by-design principles, identifying and treating security risks throughout the lifecycle
• Own your work end-to-end — analysis, design, implementation, testing, deployment, and support (in simulation and production)
• Learn and follow the software delivery process at DBG

Your profile:

• University degree in information technology, engineering, or similar (CTU, UK MFF)
• Proficient in written and spoken English
• 3+ years of professional experience in software engineering
• Experience with Java or C++
• Experience with messaging architecture (event streaming, pub-sub, SOA, message-driven middleware) and message formats (XML, JSON, CSV, PDF, ...)
• Solid foundation in software design: object-oriented design, architecture and interface design, SQL
• Security-conscious: aware of application security principles and their impact on design (ISO 27001 a plus)
• Strong analytical skills: able to reason about complex systems and identify root causes
• Self-organizing, autonomous, and detail-oriented, with proactive communication and strong negotiation skills

Would be an advantage:

• Experience with Linux
• Containerization (Docker, Kubernetes, OpenShift)
• Cloud Services (AWS/Azure/GCP)
• SWIFTNet
• Previous experience in the financial sector
• Secure coding practices, threat modeling, or security tooling (e.g. static/dynamic analysis, Sonarqube, HPFortify, ISO27001)
