Select how often (in days) to receive an alert: Create Alert

In Hearing Care, we are enhancing how data science supports commercial and operational decision-making. As our SeniorData Scientist, you will work close to the business, shape meaningful use cases and help move machine learning from idea to scalable, production-ready solutions.

Making data science matter in business

At Demant, our purpose is to improve people’s lives through hearing health. In this role, you will contribute by helping our Hearing Care business use data and machine learning more effectively – not as an isolated technical exercise, but as a practical capability that supports better decisions and creates measurable value.

Turn business challenges into scalable machine learning solutions

You will join Commercial Excellence in a business-facing data science role. Working closely with commercial and operational stakeholders, you will learn how they work, understand their challenges and decision-making processes, and translate those needs into clear data science and machine learning cases.

You will manage the end-of-the-end data science lifecycle: exploring and preparing data, feature engineering, modelling, experimentation and evaluation. You will build, validate and continuously improve machine learning models, often in data environments that are imperfect, fragmented or still evolving.

A key part of the role is making sure solutions can live beyond the prototype. Together with MLOps, Data Engineers and Architecture, you will help move models into scalable production solutions and follow their performance over time, including model drift, retraining needs and continued business relevance.

The role gives you the opportunity to help shape how data science is used across Hearing Care. As our AI maturity develops, you will have room to shape ways of working, build closer collaboration between business and technology, and build solutions that are practical, governed and adopted in the organisation.

Bring technical depth and business curiosity

You are an experienced data scientist who enjoys getting close to business problems and finding a pragmatic path from data to value. To be effective in the role, we expect that you:

• Have a bachelor’s or master’s degree in data science, Statistics, Computer Science, Mathematical Modelling, IT or a similar relevant field.
• Bring 3+ years of professional experience in data science, machine learning, statistical modelling and predictive analytics.
• Are comfortable across the model development lifecycle, including data exploration, feature engineering, training, validation, production handover, monitoring and retraining.
• Have solid Python and SQL skills and can write clean, maintainable code aligned with good software-development practices.
• Can work with imperfect or fragmented data and identify what is needed to make a use case feasible.
• Communicate complex analytical findings clearly to both technical and non-technical stakeholders.
• Are familiar with MLOps practices, CI/CD, model monitoring and production handover.
• Have experience working with cloud-based data platforms; we use GCP.
• Are fluent in English, as it is our company language.

Want to join us?

No later than August 31th, 2026.

We look forward to hearing from you.
