Lead Software Engineer

SimCorp

Copenhagen, Denmark

WHY THIS ROLE IS IMPORTANT TO US    

We are looking for a Senior Software Engineer to join the Transactions & Private Debt product area and contribute to business-critical functionality used by our clients in their daily investment operations.

You will work as part of an experienced engineering team, contributing to backend development, component design, performance, reliability and maintainability. The work is technically interesting because it combines complex business logic, long-lived enterprise software and the need to keep improving how we build and deliver functionality.

Most of the current product logic is written in APL, while we are increasing our use of C#/.NET in new development, integrations, cloud enablement, and platform modernization. You do not need prior APL experience. We will provide training and support and we are looking for someone who is curious enough to learn what is needed while bringing strong engineering practices from C#/.NET.

You will work with experienced engineers across locations and have room to influence how we build, modernize and evolve the product.

 WHAT YOU WILL BE RESPONSIBLE FOR  

As a Senior Software Engineer, you will help the team build reliable, maintainable and well-tested backend solutions. In practice, you will:
Design, implement, test and maintain backend functionality using APL and, where relevant, C#/.NET
Contribute to component design, code quality, performance and long-term maintainability
Work closely with product managers, engineers and other stakeholders to understand requirements and deliver client-relevant functionality
Improve reliability and delivery through code reviews, automated testing, CI/CD and pragmatic engineering practices
Investigate technical issues, performance bottlenecks and bugs and help design sustainable solutions
Share knowledge with colleagues and contribute to technical discussions within the team

YOUR QUALIFICATION   

Bachelor’s degree in computer science, information technology, or a related field  
Solid experience with C#/.NET and backend development
Good understanding of object-oriented design, clean code, APIs, and integration patterns
Experience with automated testing, code reviews, CI/CD, and Git-based workflows
Ability to work with complex business logic and collaborate with both technical and non-technical colleagues
Interest in learning APL. Prior APL experience is not required
Experience with Azure or cloud-based development is an advantage, but not a prerequisite
