Giant Leap Trainee, GenAI Developer

Location:

Helsinki, FI

Are you ready to take a Giant Leap? We’re looking for a GenAI Developer Intern for our Giant Leap program – a project-based internship at our HQ in Vantaa. The project: AI-Assisted Test Procedure Generation Module is about the development of a pilot AI-based module to generate standardized test procedures (e.g. FAT/SAT) using templates and project input data, supporting automation within Projects, Caretech and Services (PCS). As a Giant Leaper, you will get your own project to lead for three months, starting in June.

Vaisala is a global leader in measurement instruments and intelligence helping industries, nations, people, and the planet to thrive. From predicting hurricanes to optimizing renewable energy production, our technology is used where it matters the most – from data centers, windfarms and laboratories to airports, the Arctic and even the surface of Mars. For a second year running, Vaisala got recognized in TIME Magazine's World's Best Companies in Sustainable Growth 2026 study. Our team of close to 2,500 experts and 62 nationalities around the world is committed to taking every measure for the planet. Driven by our shared purpose, curiosity, and pioneering spirit, we stay ahead and make a difference. At Vaisala, you don't have to fit in to belong.

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.

Develop an AI-assisted test procedure generation prototype

Define and apply validation checks for completeness and structure

Test and refine standardized templates using real project examples

Automate repetitive engineering documentation work
