Digital Growth Manager - Sea Magik
About Sea Magik
Sea Magik is a British mineral-based skin and haircare challenger brand on a mission to become the authority in mineral treatments for skin and scalp health.
For over 40 years, we have pioneered the use of sea minerals to help people manage dry, sensitive, and problem skin and scalp, restoring comfort, confidence, and control. Our products are trusted by leading retailers including Holland & Barrett, as well as spas and professionals across the UK.
Backed by recent investment, we are now entering an exciting new phase of growth. We are scaling our ecommerce and Amazon channels, launching new products, and expanding our global reach.
We are small enough for every person on the team to make a real impact, but established enough to have proven products, loyal customers, and significant untapped potential.
This is a rare opportunity to join a purpose-driven challenger brand with genuine heritage and strong growth momentum.
