Student Assistant in Marketing & Communications

Are you about to start your master’s degree and looking for a student job where you can gain real hands-on experience within marketing, communication, digital platforms, and international business development?

At Cotes, you will join an international Sales & Marketing team working with industries that play a key role in the green energy transition, including Wind Energy, Battery Manufacturing, and Industrial Applications.

Here, you will gain practical experience in a growing B2B company where marketing, communication, technology, and commercial development come together. You will be involved in meaningful projects from day one and take on real responsibility in a student job with varied tasks.

About the Position

As a Student Assistant in the Cotes Sales & Marketing team, you will work closely with colleagues across marketing, sales, business development, and management.

You will support a broad range of activities including:

• Content creation and storytelling
• Social media campaigns and digital marketing
• AI-supported marketing and communication workflows
• Website and CRM/CMS development (HubSpot)
• Market and competitor research
• Sales enablement and business development support
• Video, presentations, newsletters, and campaign execution
• Analytics, reporting, and marketing automation
• Internal communication and branding initiatives

You will join an international Sales & Marketing team based at our HQ in Viby J near Aarhus.

The position is office-based with flexibility around studies and working hours, but it is not a remote-only role.

We believe collaboration, creativity, and learning happen best when we work together in person. This supports both teamwork and effective execution.

Practical Information

• Working hours: 10–20 hours/week depending on studies and workload
• Salary: 169 DKK/hour
• Flexible planning around exams and studies
• Lunch arrangement available at employee price
• Start date: Flexible, but preferably August/September 2026

What We’re Looking For

We imagine that you are about to begin your master’s degree within marketing, communication, digital business, media, IT, business development, or a related field.

We imagine that you:

• Have a curious, solution-oriented and proactive mindset
• Enjoy both creative and analytical work
• Are comfortable working with digital platforms and new technologies
• Communicate clearly and work well with others
• Are structured, detail-oriented and motivated to learn
• Have an interest in marketing, communication, AI tools, or digital platforms
• Speak and write English fluently

Danish language skills are an advantage, especially for local communication and content creation, but they are not a requirement.
