About KURK

KURK is a mission-driven health brand tackling one of the world’s biggest health challenges: inflammation, chronic pain, and longevity.

Founded by two best friends after their own battles with cancer, we are developing the world’s best natural solutions for common health challenges in our own lab. Today we have:

• Vertical integrated product pipeline with industry leading repeat purchase rate and a Science Advisory Board with 2 medical doctors and 3 health Ph.D.’s
• Fast DTC growth across the UK, US, and Australia
• A clear plan to triple revenue over the next 18/24 months

We’re building the defining natural health brand of the next decade — and now we need a Head of Digital Marketing to own and scale our online growth engine.

• Own reporting dashboards to provide real-time growth and performance insights.
• Build and manage a lean team (growth marketer, CRM exec, paid media buyers).
• Collaborate with our science, creative, and operations teams to launch products and campaigns.
• Work with CEO and board to align digital strategy with overall company growth.

About You

• 3+ years in digital marketing / e-commerce growth, ideally in DTC wellness, supplements, or CPG.
