Internship: Market Research & Business Development

Sassenheim, The Netherlands
Full or part-time
Intern / Student

Your (space) mission

How do you identify new markets for technology that is normally used in space missions?

At cosine, we develop advanced technology for international space exploration projects. The same technology may also offer opportunities much closer to home. During this internship, you will investigate which markets, companies, and organizations could benefit from our innovations.

You will explore new application areas, analyze attractive markets, and identify potential customers and business partners. In doing so, you will provide valuable input for cosine's commercial strategy and future growth.

Why choose this internship?
  • You will work on a real commercial challenge with clear business impact
  • You will learn how market research contributes to business development and commercial growth
  • You will be given a high degree of freedom and responsibility
  • You will gain experience in an innovative company developing technology for both space and terrestrial applications
  • You will collaborate with experts from a variety of disciplines
The internship is available for one semester. The start date is flexible and can be agreed upon together.

Tasks & responsibilities

During your internship, you will:
  • Research new markets and industries where cosine's technology could potentially be applied
  • Identify companies and organizations that could be interesting as customers or strategic partners
  • Analyze market developments, trends, and business opportunities
  • Collect, organize, and present commercial insights and potential leads for our sales team
  • Collaborate with colleagues from engineering, marketing, and sales
  • Have the opportunity to attend networking and business events

Your profile

  • You are currently pursuing a Bachelor's degree in Commercial Economics, Marketing, Business Administration, or a related field
  • You are in the third or fourth year of your studies
  • You are curious and enjoy researching markets, companies, and commercial opportunities
  • You work in a structured manner and can clearly organize and present information
  • You communicate easily, both verbally and in writing
  • You have a good command of both Dutch and English
  • You live in or near the Leiden/Sassenheim area
  • An interest in innovation, technology, or space is a plus, but certainly not a requirement
