.NET Developer

As a .NET Software Developer, you will create, change and run the application landscape that manages the wealth and risks of more than 100 billion worth of assets under management.

You will work in a multidisciplinary scrum team of eight people, serving the Investment Management division. Our team aims to deliver business value by efficiently using modern technologies, helping to transform our Investment Management division into a high-tech, data-driven organization. We create and manage applications, APIs, data gathering and user interfaces. Given the high stakes of our business, we place great importance on the quality and safety of our software and data, ensuring our applications run smoothly with minimal errors or potential impacts from mistakes.

The Operations DevOps team enables and supports colleagues within Securities Operations by managing solutions for middle office activities, for example position keeping and collateral management. The team also creates and manages part of the foundation to expose holdings and transactions data to other teams.

Next to the development work, the team serves as the first point of contact for all technical questions related to our product and assists with Business as Usual (BAU) issues for the operations domain. Each team member is involved in breaking down product challenges, gathering requirements, designing solutions, making architectural decisions, and engaging in discussions with stakeholders.

Your experience

Passionate about technology, collaborative and analytical, this is how we can best describe you in the position of .NET Developer.

You also have:

  • A Bachelor/Master’s degree with at least 5 years of recent experience with C#/.NET development;
  • Experience with Cloud (Azure/AWS) and relational databases (i.e. SQL);
  • Experience with API design (REST) and automated testing;
  • An interest in understanding financial markets and processes;
  • Knowledge of OAuth2 protocol, Python and containers would be a bonus;
  • A drive to learn and experiment.

There will be one assessment before the conversation, and a technical assessment after the first conversation.
