Senior Business Data Analyst

As a Senior Business Data Analyst, you will shape the development of governed business logic in the Risk & Finance domains at NN Bank. Based in The Hague, you will work with a small, high-impact team to standardise and centralise regulatory reporting and capital requirements calculators. This role combines strong business insight with the ability to write production-grade code. In doing so, you will help NN take essential steps towards becoming a fully data-driven A-IRB bank.

What you are going to do

You will develop, test and implement governed calculators in our Model Factory platform. Your work directly improves NN Bank's risk control, regulatory compliance and capital efficiency. You will:

• Translate business requirements into tested and documented logic using PySpark on Azure Databricks
• Develop and maintain calculators (e.g. Definition of Default, RWA, collateral indexation) in line with governance standards
• Collaborate with data and infrastructure teams to ensure high-quality, reusable and transparent implementations
• Support end-users, validators and auditors by explaining logic, outcomes and usage conditions
• Take initiative in shaping best practices, documentation and quality standards for a newly formed team

What we offer you
NN invests in an inclusive, inspiring work environment and skills and competencies for the future. We match this with employee benefits that align with what is needed today and in the future. This way, we allow our employees to get the best out of themselves. We offer you:

• A salary between €5,765 and €8,236, depending on your knowledge and experience
• A 13th month and holiday allowance, paid with your monthly salary
• 27 vacation days for a 5-day working week and one Diversity Day
• A modern pension administered by BeFrank
• Plenty of training and learning opportunities
• NS Business Card 2nd class, which gives you unlimited travel, also privately. Do you prefer to travel with your own transport? Then you can declare the kilometres travelled
• Allowances for setting up your home office and for internet use

Who you are

You are a senior-level professional who combines analytical depth with a strong understanding of the business context. You enjoy building from scratch and thrive in environments where you help shape the way forward. You also have:

• A Bachelor's or Master's degree in Finance, Economics, Information Systems or a quantitative field
• At least 5 years of experience in coding with PySpark on Azure Databricks, using Git workflows
• Specific experience with Definition of Default or similar risk calculator logic in a banking context
• Familiarity with regulatory expectations in the Risk & Finance domain
• Strong communication skills and the ability to collaborate across disciplines

Who you will work with

You will join the Model Factory team in the Data Management Office, within the CRO domain of NN Bank. This newly formed team focuses on standardising risk and finance logic across the bank. The team will consist of three people working closely with platform operations, infrastructure and data sourcing teams. It is a setting where the lines of communication are short, people are approachable and help is always nearby. Despite NN Bank's compact size, you benefit from the scale, structure and development opportunities of the broader NN Group. Frequent social events and team activities also offer opportunities to connect beyond work.
