WHO WE ARE

For over 50 years, we have worked closely with investment and asset managers to become the world’s leading provider of integrated investment management solutions.

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.

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.
