Full stack developer

West Hampstead, London

A bit about us

Callaly is on a mission to reinvent femcare and be the most forward-thinking company for people with periods. We believe that nobody should have to put up with products that don’t work or haven’t improved in decades. Nor should they have to buy tampons and pads in one absorbency or in bulk from supermarkets just because that’s what they’ve always done. That’s why we launched a delivery service selling a much better option: Tampliners, the first real design innovation to tampons in 80 years. Since our soft launch in 2018 we’ve sold tens of thousands of Tampliners, and have won and been nominated for prestigious innovation awards. The Independent named us one of the “period-positive startups revolutionising the multi-billion pound feminine care industry” and we made it into Dezeen’s top 10 most forward-thinking designs for women.

What you’ll do

We’d like you to:

Have a 360˚ holistic view of web development, with a rich understanding of everything from DevOps to UX to SEO.

With our new product launch, the responsibilities of the full stack developer will likely see a shift as the company moves from pre-launch into post-launch and beyond, providing a unique view into the exciting and challenging realities of an early-stage startup.
