Please send an informal email to Eero - feel free to send it in Finnish if you wish - to learn more and to start a conversation.
From your end, you can tell, for example, how do you see your fit to our culture and values, what things you already have experience on, what you'd like to learn, what you are interested in, what have you done before, what things you are interested in, a CV or a link to your LinkedIn profile, desired salary, etc. If you have a portfolio or a github account or similar, please provide a link.
Ps. If you think you have nothing new to learn and/or you feel you won't have any need what so ever to prove yourself to your new colleagues, we might not be a best fit for you.
