Growth Marketing Specialist (Freelance)

At Brenger, we’re committed to transforming the bulky goods transportation landscape, from A to B, making it smarter, faster, and more sustainable. Our innovative platform enables couriers to maximize their earnings while offering consumers affordable transport solutions for large items like beds, bicycles and sofas.

• Strong analytical skills and experience with conversion funnels.
• Proven experience with growth experimentation (both product-led and communication-driven).
