The team improves and supports the Asset Manager module in our SimCorp Dimension product. We use a variety of technologies, but the main ones are C# and an Oracle database. You will be working with backend and APIs. The present and near future main topics are good maintainability, high system performance, continuous integration, and delivery, and moving into our unified platform for cloud. We welcome engineers who are ready to grow further in technical leadership as well as those who already have experience guiding others.

• Contribute to automated testing, continuous integration, and continuous delivery practices that enable predictable, high-quality releases.
• Help shape technical decisions and share knowledge through code reviews, pairing, mentoring, and constructive collaboration across the team.

WHAT WE VALUE

• Experience developing production software with C# and/or APL, or comparable experience that demonstrates strong backend engineering capability.
• Interest in contributing to technical design and helping the team make practical decisions about scalable, high-performing applications, services, or APIs.
• Familiarity with software delivery practices such as automated testing, version control, continuous integration, and continuous delivery.
• Openness to using AI-assisted development tools thoughtfully, while maintaining sound judgement around quality, security, and maintainability.
• Curiosity and willingness to learn additional technologies, including Dyalog APL, and to deepen your understanding of investment-management software.
• A collaborative approach to solving problems, sharing knowledge, and growing into technical leadership.
• Experience with Angular, Node.js, JavaScript/TypeScript, HTML, CSS, Oracle databases, or financial systems is welcome but not required.
