Web Developer, Opera Fintech

On our team you will work surrounded by supportive, experienced team members that have a curiosity for both technology and the product domain we work in. Our team enjoys a lot of independence building products that address the real needs of millions of people.
The Gothenburg office has a relaxed, casual and fun atmosphere with Friday beers, board game evenings, great comradery and above all, a lot of laughs.
