Coating Engineering Intern

Working both inside and outside the lab, you optimize our greenhouse spray coating’s optical performance and tackle the rheological challenges facing film formation. Working with experts in the field, you support our team to deliver a functional and scalable solution to increase greenhouses’ yield by more than 7%.

Internship · Delft

Join today, shape tomorrow.

The start of our step towards greenhouse horticulture together with you.

Who we are? We are a technology company from Delft, engineering coating, solar and sensor solutions for the global energy transition. Across all these solutions, we consistently aim to change the perspective on how current materials are used and implemented, as well as challenging the system innovation behind them.

Among which is an optical coating we are developing for greenhouses. By converting UV light to photosynthetic active radiation (PAR) as well as making it diffuse, we can increase the yield of a greenhouse by as much as 7.5% annually. We adopt industrially recognized practice to spray our optical coatings on greenhouses. To optimize our coating’s rheology and film forming properties, we are looking for an addition to the team who can talk to professional sprayers and chemists to gain relevant insights and implement them in our formulation. Not being afraid of getting the hands dirty, you work both in- and outside the lab with scientific and practical works to develop a functional and scalable solution for greenhouses.  

What you’ll be doing: 

  • Perform scientific and technical studies for spray coatings 

  • Deposit and characterize optical coatings

  • Work with professionals inside and outside the lab 

  • Develop and experiment with strategies to control coating’s rheological and film forming properties

Who we’re looking for: 

  • You are approaching the end of a Bachelor’s or Master’s degree in a technical oriented education, such as (but not limited to) chemical engineering, material engineering, and mechanical engineering
  • You have experience with optical coatings
  • Experience with rheology control (e.g. shear thinning) or spray coating is a plus
  • You are fluent with English (both written and verbally)
  • Dutch speaking is a plus.
  • You understand (or are eager to learn) rheology.

What you can Expect? 

  • Be part of a growing organization, with the mission of transforming the built environment into a smart, sustainable, and healthy eco-system

  • Have variety in your daily activities through active knowledge sharing, presentations,
  • Work-life balance
  • Open environment to express your opinion and share new ideas
  • Work in an English environment, with 12 different nationalities
  • Daily lunch & fruits (when we’re in the office)
