We will help prevent a climate crisis by freeing the world from fossil fuels. Our breakthrough direct air capture technology captures CO2 from the atmosphere and produces hydrogen in parallel.

The clock is ticking. What are you waiting for?

Our goals are ambitious. We need people who are inspired and motivated to turn these aspirations into reality; to grow and develop with us.

We are looking for working students to join our CO₂ desorption team. This team focuses on scaling up an electrolyzer that releases CO₂ from its captured state, helping push our carbon removal process toward industrial scale.

Specifically, you will…

• Set up and maintain experimental systems for CO₂ desorption.
• Ideate and conduct electrochemical tests as part of the desorption research team.
• Prepare samples for chemical, mechanical, and electrochemical analysis.
• Analyze and process experimental data and summarize key findings.
• Support general laboratory operations and ensure a safe, organized workspace.

Your first 12 months in the role: expectations and deliverables
Months 0-3

• Get to know our team, culture, and the fundamentals of our technology and lab setup.

• Assist in experimental setup for electrolyzer testing and CO₂ desorption studies.

• Learn and apply lab safety standards, documentation practices, and analytical techniques.

• Begin contributing to sample preparation and running electrochemical tests under supervision.

Months 3-6

• Independently run standard electrochemical test protocols and analyze results.

• Maintain detailed experiment logs and assist in report writing for internal knowledge sharing.

• Support data processing and improve existing lab documentation.

• Begin contributing to refinement of experimental procedures and basic troubleshooting.

Months 6-12

• Take ownership of a specific technical workstream (e.g., electrolyte development, material screening).

• Contribute to hypothesis-driven experiment design and structured analysis of results.

• Collaborate with other functional teams (e.g., modeling, systems, process engineering).

• Optionally, initiate and scope a thesis project aligned with your contributions.

• Enrolled in a Bachelor’s or Master’s program in Chemistry, Chemical Engineering, or a related field (Master’s preferred).

• Experience in electrochemistry and the role it plays in climate solutions.

• Known for a structured, hands-on approach and attention to detail.

• Motivated by the opportunity to contribute to real-world experiments with measurable impact.

• Comfortable working both independently and as part of a tight-knit research team.

• 20 days vacation plus public holidays to ensure you also have the down time needed to rest and recharge.
• The possibility to grow and shape your role.
• Working with founders who understand - and invest time in - the importance of building a healthy and sustainable organization.
• Open and transparent communication on company development.

This role cannot be done fully remotely.We require someone who lives within commuting distance to Essen.

GCT wurde im September 2022 mit dem Ziel gegründet, eine kostengünstige, robuste Direct Air Capture-Technologie zu entwickeln, die CO2 mit weltweit führenden Energiewerten abscheidet und gleichzeitig Wasserstoff als Nebenprodukt liefert. Die Technologie des Unternehmens basiert auf 15 Jahren Forschung und hat sich in verschiedenen Größenordnungen bewährt. Seit seiner Gründung hat das Unternehmen mehr als 45 Millionen Euro an Finanzmitteln von führenden Risikokapitalgebern und renommierten Business Angels erhalten.
