We’re looking for a Data Scientist Trainee for our Giant Leap program – a project‑based internship in our Harpenden Office, UK. You will join our Vaisala Xweather team specialised in Finance and Insurance to enhance our Weather Data Cleaning Systems. This position is central to our operations, focusing on the creation and maintenance of high‑quality datasets used by the weather risk management trading community.

As a Junior Data Scientist trainee or a Meteorologist with significant Data Scientist experience trainee, you will help in advancing our applied machine learning capabilities to clean Historical Weather Data. You will focus on exploring and developing new features, testing a variety of modeling approaches, and supporting innovation in how we use supervised learning for complex time‑series and structured data challenges.

Responsibilities:

  • Develop, improve and automate Data Cleaning Techniques, ensuring high accuracy and reliability.
  • Experiment with a range of modeling techniques for the various weather variables: temperature, rain, wind, etc.
  • Collaborate with software developers to integrate promising approaches into larger workflows.
  • Automate clients’ data cleaning techniques used as an input to ML models.

The role will be predominantly office based.

Qualifications:

  • Knowledge of meteorological datasets.
  • Hands‑on experience with machine learning libraries (scikit‑learn, XGBoost, PyTorch, TensorFlow, or similar).
  • Familiarity with statistical methods.
  • Proficiency in Python, with strong analytical and data manipulation skills.
  • Familiarity with software development, ideally in C#.
  • Excellent communication skills for liaising with internal teams and external stakeholders.
  • While the core modelling is in Python, you will need to integrate your Python models/APIs with existing C#/.Net applications.

Giant Leap is a unique opportunity for you to be the project manager of your own project, with the support of your teammates and project supervisor. Every year, these projects are carefully selected by our leadership teams, meaning that you get to work on real‑life questions that are important for us as a company. We invest in your growth with training sessions throughout the summer. Along with lessons from your own field and work life in general, you have a chance to learn, for instance, presentation skills, project management and problem solving. Connections built with fellow Giant Leapers, Vaisala’s brilliant experts and our leadership form an invaluable network for your career. Many of our former Giant Leapers have also gone on to build impressive careers at Vaisala after the program.
