Job description

SimCorp has over 50 years of experience working with large global investment and asset managers. With more than 3,500 colleagues worldwide, the company is committed to creating a culture that values diversity, continuous learning and responsible business practices. It is an equal‑opportunity employer.

Why This Role Is Important

This position is a key part of SimCorp’s Private Debt initiative – a high‑priority project that is expanding to meet increasing client demand. The Senior Software Engineer will help design and deliver the core back‑office application that enables clients to make investment decisions.

Technology Focus

The Private Debt module is primarily built in APL, with strong engineering practices around quality, code review, continuous delivery and reliability. As the system evolves, more C#/.NET work will be added, especially around architecture, cloud integration, platform enablement and new components.

Responsibilities

• Design and develop backend systems in APL (current core).
• Guide engineers through code reviews, technical planning and Agile practices.
• Partner closely with Product and other engineering peers to deliver business‑critical outcomes efficiently.
• Drive code quality and reliability through unit testing, integration testing, CI/CD and established engineering standards.
• Identify performance bottlenecks and bugs and devise sustainable solutions.
• Use Git‑based workflows and work effectively in a continuous integration environment.
• Collaborate with cross‑located teams and contribute to shared ways of working across sites.
• Communicate effectively with business stakeholders and understand client‑specific requirements.

Qualifications

• Bachelor’s degree in computer science, information technology or a related field.
• 3+ years of software development experience.
• Strong engineering fundamentals: object‑oriented design, architecture patterns, clean code and pragmatic problem solving.
• Solid experience in C#/.NET (Core or Framework), building backend APIs, services and integrations.
• Familiarity with REST APIs and messaging concepts (e.g., service bus patterns).
• Proficient with code versioning tools such as Git.
• Experience with automated testing, CI/CD and strong code‑review habits.
• Strong problem‑solving skills with the ability to work independently and as part of a team.
• Comfortable collaborating with multiple stakeholders and communicating clearly in an international environment.

APL Readiness

Prior APL experience is not required. Curiosity and a willingness to learn are the key qualifications. SimCorp provides comprehensive training and support to help engineers become proficient in APL, and the company partly owns Dyalog APL.

Nice‑to‑Have

• Finance or regulated‑industry experience.
• Exposure to vector‑based or functional languages (useful for ramping up in APL).

Benefits

• Competitive salary, bonus scheme and pension.
• Flexible work hours and a hybrid workplace model.
• IP sprints that give you time to develop skills and contribute to company projects.
• Individual professional development pathways tailored to the engineer’s interests.
