Cinnamon workplace culture is all about passion, friendliness and having fun! Hence the low staff turnover rate when comparing with similar companies.

Even though you’re already well compensated, we also offer bonus perks for contributing beyond your core work, such as writing blog posts, hosting presentations, participating in meetups, and celebrating birthdays and work anniversaries. 🎉

The projects

We work on projects big and small, but with one thing in common: our clients are cutting-edge companies bringing advanced and innovative solutions to the market. You will not be bored.

Remote work

Do you feel most productive working from home? Or you like to be surrounded by your colleagues and enjoy the office vibe? You can have both. Create your own perfect home/office balance.

The growth

We support continuous learning through mentorship, internal knowledge-sharing, and access to selected educational resources. Depending on the role, employees may also benefit from additional training opportunities and curated courses.

The fun

We do encourage spending time together whether it’s grabbing coffee, hanging out after work, or coming into the office to connect with the team. After your first year at the company, you’ll also get an extra 2 days of vacation.

The offices

Our office is located at Algebra University, where we work from their modern coworking space. The campus offers great amenities including a cafeteria, comfortable workspaces, and everything you need for a productive day. And when it’s time for a break, there’s an excellent bar just across the street that’s perfect for coffee or after-work drinks. ☕
