Founding Growth Marketer

We’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!).

What You’ll Do

- Work closely with our CEO to refine our ideal customer profile and develop clear buyer personas and use cases

- Build the narrative for Magentic as a category-defining AI platform for procurement

- Design and run rapid experiments across acquisition channels to build our growth playbook

- Leverage modern AI and automation tools to analyse, track, report and execute

- Work closely with founders, sales, and product to turn customer insights into product and messaging improvements

- Have a strong bias for execution and ownership

- Are comfortable operating across the full marketing stack (customer research, messaging, campaigns, analytics).

- Strong mix of analytical thinking and creative storytelling.

- Have a highly experimental mindse...
