• Photography & Videography: Organize and produce visual content, including professional photography, drone footage, team photos, and project shoots at greenhouse locations.
• Social Media Management: Develop and maintain a content calendar, manage our LinkedIn presence, and identify opportunities to increase our reach and engagement.
• Website & Communication: Contribute to improving our website and ensure our messaging is clear, consistent, and aligned with our brand identity.
• Marketing Strategy: Identify creative ways to increase brand awareness, communicate our impact, and position Thermeleon within the sustainable energy and greenhouse horticulture sectors.

• You have excellent communication skills in English. Dutch is a plus.
• You're creative, proactive, and enjoy taking ownership of projects from idea to execution.
• You're comfortable working in a dynamic startup environment where priorities can evolve and there's room to experiment. Affinity with sustainability, technology, and innovation is a plus.

Benefits

• The opportunity to shape and develop the brand identity of a growing sustainable technology company.

DIVERSITY

We strive for diversity within our team, including education, background, specialization, and gender balance. Research shows that men often feel confident enough to apply when they meet 60% of the requirements, while women tend to apply only when they meet every criterion. So, if this role sounds like a good fit but you're not entirely sure you meet all the requirements, we'd still love to hear from you!
