Job description

SimCorp is an equal opportunity employer.

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

• 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

Qualifications

• 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

Nice to have

• Experience from fintech, financial services or another regulated industry
• Exposure to functional, array-oriented or vector-based programming languages
• Experience with Azure services or cloud-based development
• Experience mentoring other engineers or taking ownership of a component

Benefits

• Global hybrid work policy – 2 days a week from the office, remote other days (optional)
• Growth and innovation – Every 6th sprint is reserved for planning and innovation
• Self-direction – High degree of self‑organization, freedom to plan, organize and design work
• Inclusive and diverse company culture
• Pension and health benefits and bonus
• Work‑life balance – Equilibrium between professional responsibilities and private life
• Empowerment – All voices are valuable and must be heard; involved in shaping work processes
