WHO WE ARE?
For over 50 years, we have worked closely with large and global investment and asset managers to become the world’s leading provider of integrated investment management solutions. We are 2,500+ colleagues with a broad range of nationalities, educations, professional experiences, ages, and backgrounds in general.
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.
