ICA is Sweden's largest retailer, headquartered in Solna, Stockholm. The company operates grocery stores, ICA Bank, ICA Insurance, Apotek Hjärtat pharmacies, and a nationwide logistics network. ICA has been part of Swedish daily life for over a century.

Zendev is a Swedish-Bosnian software company. We provide engineering services to clients across Europe, with a focus on Scandinavia. We're built on long-term partnerships, not transactional relationships.

If this sounds like something you'd enjoy, we'd like to hear from you.

Our developers already work daily with ICA's teams in Sweden. We understand the questions you might have:

• What's it like working with a Nordic partner?
• How does collaboration between Sarajevo and Sweden actually work?
• What should I expect in my first months?

That's exactly why we're here.
