Jesse, Geographical information system development

"Vaisala has great company values, which are easy to agree with. Vaisala also takes good care of their employees. I would suggest Vaisala as an employer for everyone who is curious enough and interested in challenging and important work!”


Jesse Hietanen, student of University of Helsinki, joined Vaisala in 2015 as a Giant Leap intern. Jesse is now working as Software Engineer at Vaisala.

"I was looking for an internship and Giant Leap program got my attention. Vaisala has great reputation and I felt that Vaisala is doing important work and making our lives better. Stories and descriptions from previous year’s Giant Leapers gave also very good impression of the program. Projects felt also challenging enough, not forgetting the fun activities.

During my internship I worked in the Software Development unit of Vaisala. My project was about planning and developing an application for reading and modification of geographical data, using open source tools and industry standards. If I ever got stuck with my project or needed help with something, I could easily ask help from anyone, which was really important! I had also chance to visit our Birmingham office, which was useful and fun.

I am currently studying in the University of Helsinki, majoring in Geographical Information Systems (GIS). As minors, I have studied for example computer science and different environmental studies. I feel that skills and knowledge learned in the university was really useful for my project. I could apply the knowledge I had and actually give new ideas to the company.

I personally feel that I learned a lot from the internship. I learned new things regarding my studies and also a lot of about project and time management. Also working with international team, consisting of brilliant people, was really unique and instructive opportunity. I was really surprised how well people welcomed me and how interested they were in my project. In general, my time as a Giant Leap intern was really instructive and fun.

Vaisala has great company values, which are easy to agree with. Vaisala also takes good care of their employees. I would suggest Vaisala as an employer for everyone who is curious enough and interested in challenging and important work!”
