Open Roles

Bring brain-based innovations to women everywhere.

At Samphire, we’re building the world’s first brain stimulation therapies designed specifically for women’s chronic pain and hormonal health. Our first product, Nettle™, is a wearable neurotechnology for PMS, PMDD, and endometriosis; and we’re just getting started. Our Samphire app unites Nettle™ users, as well as all women living with cycles and chronic conditions linked to them, and allows women to understand their wellbeing through a brain lens.

We’re looking for an exceptional Content & Growth Manager to join our fast-growing women’s health startup.
