Job description

Create your own future

As a Senior .NET Developer in the Nexus Team, you will help build the foundation for future digital solutions within our Private Clients business.

The Nexus Team is responsible for developing an Operational Data Store (ODS): a central data platform that brings together information from multiple source systems, standardises it, and makes it available for applications across the organisation. By creating a consistent and reliable data layer, we enable development teams to make better use of data. While this is a Senior .NET Developer role, the focus is primarily on backend development.

This is a highly autonomous role in a lean team. You will not only build solutions, but also help shape the future of the platform. You will work in a complex environment where business processes, applications and data models come together.

We believe that the best solutions come from truly understanding the problem first. That's why we're looking for someone who is curious and enjoys investigating how things work, actively engages with stakeholders, challenges assumptions, and translates complex questions into scalable technical solutions.

Your responsibilities

• Design, build and maintain services and applications on top of the Operational Data Store
• Develop backend functionality and integrations using C# .NET and Azure SQL
• Help migrate functionality from existing APIs to the new data layer where appropriate
• Integrate and standardise data from multiple source systems
• Contribute to the evolution of the data model and platform architecture
• Work closely with business stakeholders, architects and development teams to understand requirements and identify opportunities for improvement
• Investigate complex data and application landscapes and propose solutions that balance business and technical needs
• Take ownership from analysis through implementation

Your talents

As a Senior .NET Developer, you are independent, analytical and proactive. You enjoy working in an environment where not everything is defined upfront and where discovering the right solution is part of the job.

You are someone who wants to understand how things really work. You ask questions, challenge assumptions and are comfortable forming and defending your own view on technical and functional decisions.

In addition, you have:

• At least 5 years of experience with C# .NET development
• Strong knowledge of SQL and relational databases
• Experience building integrations between systems and applications
• Experience working with Azure-based solutions
• An affinity for data modelling and complex data structures
• Strong analytical and problem-solving skills
• Excellent communication skills and the ability to collaborate with both technical and non-technical stakeholders
• Experience working in Agile teams
