Data scientist (CAS NN Group)

Are you passionate about solving complex problems with data? Do you want to be part of a team that’s pioneering new ways to use AI and analytics in business?

At NN Group Corporate Audit Services (CAS), we’re building a brand-new team focused on driving innovation in audits. As a data scientist, you’ll have the unique opportunity to shape how data and AI uncover risks, enhance processes, and transform decision-making across our global organization. With access to advanced tools, mentorship, and exciting challenges, this is your chance to make an impact and grow your career in a supportive, collaborative environment.

Within Corporate Audit Services, we are setting up a brand-new, dedicated data and AI team within NN CAS. This team is all about driving innovation and transforming the way audits are conducted. As one of the founding members, you’ll play a key role in shaping how data and AI are used to uncover risks, enhance processes, and support decision-making across NN’s business units - from NN Life, NN Non-life and NN Bank in the Netherlands to NN Spain, NN Greece, and beyond.

This isn’t just a job—it’s an opportunity to be part of something new and exciting, where your ideas and skills will directly contribute to building a smarter, more data-driven future for NN. If you’re looking for a challenge, a chance to grow, and the opportunity to work with talented professionals in a fast-evolving field, this role is for you.

Your main goal is to create data science solutions for internal audits and reviews, working closely with your audit colleagues. You’ll collaborate with teams in The Hague and across NN’s international business units, building solutions that make a real impact. This role offers you a unique opportunity to gain insights into the processes and systems used across our diverse organization—from NN Life, NN Non-life, and NN Bank in the Netherlands to NN Spain, NN Greece, and beyond.

This role provides you with a unique opportunity to gain insights into the processes and systems used across these diverse business units. Your expertise will enable you to advise colleagues on the capabilities of specific systems or direct them to solutions implemented elsewhere.

From our internal, independent audit team, we ensure qualitative, in-depth investigations for the products and services within NN Group. And when we say in-depth, we mean it. We dive deep into the processes of the value chains to thoroughly examine the outcomes. We do not conduct standard checks; we delve into the content. This way, you can uncover in detail what is happening and make a real impact. Based on this, we can also challenge the business on improvements after an investigation.

What you are going to do

In this role, you will combine your passion for data with a keen ability to identify risks and develop innovative solutions that contribute to the reliability and efficiency of the processes of the organization. As a data scientist within CAS you will be conducting complex data analytics, process mining, building AI Agents for audit and building proof of concepts of controls which do not exist in the organization. Through this data-driven audit work, which spans the breadth of NN Group, you will directly contribute to NN's success. Beyond supporting your internal audit colleagues, your expertise in data and artificial intelligence will also be crucial for CAS in auditing artificial intelligence systems used by the organization.

Together with your audit colleagues you answer research and audit questions using data analytics, and you especially enjoy presenting your observations to the business and helping them understand their risks and challenges. We work on different types of audits with colleagues from different audit teams, both in the Netherlands as well as internationally.

Specifically, you develop insights into the different risks of the organization by analyzing data to truly create value for our company of tomorrow. Researching and applying new technology plays an important role. You use techniques such as Python, SQL, R, Databricks and AI as a service and LLMs, like Cognitive Services and OpenAI. If you enjoy diving into the latest AI trends to find solutions for business problems, then this job is for you.

We work hybrid at NN. We work at least 1 or 2  days at the office in The Hague, the rest of the days at home or on another NN-location. The official location of this job is The Hague.

Who you are

You are result-oriented and enjoy working with raw data, and you see value in the further adoption of data analytics and AI solutions within internal audit. Your open attitude and strong communication skills greatly help with this. Additionally, you have:

Who you will work with 

You’ll join the Corporate Audit Services NN Group (CAS), a team of about 90 auditors with diverse expertise, including actuarial, data analytics, IFRS, IT audit, and infra-security. Approximately 50 colleagues work from The Hague, while others are spread across European and Japanese business units. Despite the distance, we maintain strong connections and share experiences to help each other grow. Every year, we come together for a week-long training to learn, collaborate, and bond as a team.

As part of the brand-new Data Analytics team, you’ll focus on using data and AI to uncover risks and drive improvements across NN Group. You’ll be part of a supportive, collaborative environment where knowledge sharing and teamwork are key.
