Founding Growth Marketer
About the jobWe’re looking for our first Growth Marketer to help define how Magentic goes to market. This is a zero-to-one role: you’ll work directly with the founders to determine who our ideal customers are, what messaging resonates with them, and which acquisition channels actually work.
You’ll be hands-on, running experiments across the full marketing stack — customer research, messaging, campaigns, and distribution — and turn early signals into repeatable growth playbooks. The goal is to build the foundations of a scalable growth engine that we can later expand with a team around you.
We’re pushing the boundaries of AI with next-generation agentic systems that can manage entire procurement workflows. Our mission is to make global manufacturing supply chains robust to an ever-changing world - that’s a $3tn market opportunity.
If that’s not exciting enough - we’re backed by world-class investors including Sequoia Capital, and you’d be working along a super talented team which brings together expertise from OpenAI, Meta, Revolut, NASA and McKinsey (and that’s just the first 11 people!).
