Science Summer Trainee, Methodology Development

We are looking for a Science Summer Trainee, Methodology Development to join our Weather Research and Technology at Vaisala headquarters in Vantaa, Finland. This challenging project offers the opportunity to contribute to the early-phase development of innovative technology, mentored by our world-class experts.

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. Vaisala is recognized in TIME Magazine's World's Best Companies in Sustainable Growth 2025 study. Our team of over 2,400 experts and 59 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.

What will your summer look like?

• Gaining a fundamental theoretical understanding of the applied measurement weather sensing technique and the physical phenomena of interest
• Experimenting and innovating new frontline methodologies for multiple weather parameters using novel technologies.
• Tasks could include:

• Methodology and algorithm developments.
• Experiments and measurement campaigns carried out in Vaisala research facilities (indoor labs as well as outdoor test sites), operating novel research prototype(s) together with reference sensors and other supportive infrastructure,
• Analyses, interpretations of recorded data, validations and comparisons with system models and with reference sensors.
• Optimizations of sensor/method settings and configurations.
• Further developments in modeling the sensor and the phenomena.

• Learning data analysis skills and drawing conclusions from the results.
• Being mentored by highly experienced Senior Scientists and working with Scientist colleagues as part of the multi-disciplinary Vaisala Weather and Environment Science team.
• Working at Vaisala headquarters in Vantaa. A major part of the work requires presence in the office and labs, while minor parts of data analysis can be carried out remotely.

What will you bring?

• 3+ year physics, math, engineering student in the fields of electrical, radio-frequency, acoustics. 
• Skills in algorithm development and data analysis, methodology development 
• Advantage if experience with advanced physics models (fields, wave mechanics)
• Interest in laboratory measurements
• Curiosity and research-mindset
