10 hours ago

Kungsbron Stockholm Sweden Sweden CatalystOne Full time 250,000 - 500,000 per year


Hi students

Do you want to spend the summer working in a dynamic environment where your ideas can make a real difference? As a Business Summer Intern with us at CatalystOne Engage, you'll spend 10 weeks being part of projects that directly impact our customers and our business.

What does the role involve?

You will work on business-oriented projects in areas such as strategy, marketing, customer experience, and internal development. Projects may range from analyzing customer data and developing new ways of working to creating marketing plans that strengthen our position in new markets.

Your responsibilities

You'll take ownership of one or more projects, driving analysis, developing solutions, and presenting the final results to the team. Your work won't just be a theoretical exercise – the results will directly contribute to our development and be put into practice.

The team you'll be part of

As an intern, you'll collaborate closely with different departments – from Tech to Customer Success, HR, and Business Development. You'll be part of an engaged and down-to-earth team where previous interns have grown into permanent roles.

CatalystOne Engage 

What will you gain from the summer?


• Discuss future opportunities within the company.

• Hands-on experience with projects that directly impact customers.

• The chance to develop your skills in an inspiring environment and learn from experienced colleagues.

"During my internship, I had a fantastic opportunity to influence and contribute to CatalystOne Engage's operations through challenging and inspiring projects spanning different areas. I constantly felt encouraged to bring new ideas in a fast-paced and flexible work environment."

- Hugo Eriksson. Business Analyst & previous intern at CatalystOne Engage.

We're looking for someone who is curious, analytical, and eager to challenge both themselves and us.

 Application deadline: December 31, 2025. Please send us your CV along with a copy of your most recent academic transcript. Instead of a traditional cover letter, we'd like you to provide a short pitch explaining why you're interested in this internship. 

The recruitment process will start at the beginning of 2026, but positions may be filled on a rolling basis – so don't wait to apply
