About the Role

We are looking for a GTM Director to join our Global team. In this role, you will build, scale, and commercialise the external supply side of a global retail media ecosystem. You will bring high quality retail media inventory and ad tech capability into a single, coherent platform that agencies and clients can buy from at scale.

Sitting at the intersection of product, technology, consulting, and commercial, you’ll translate strategy into monetisable supply, unlocking scalable inventory partnerships, accelerating integrations, and driving long-term commercial growth. This is a foundational role, responsible for ensuring supply is structured, prioritised, and built for scale across markets.

If you love variety, thrive in a fast-paced environment, and embrace change with energy, this could be your right role.
