Senior Seller Acquisition Manager (Inbound)

About The Role

The Senior Inbound Seller Acquisition Manager is accountable for building and scaling a global inbound seller acquisition engine, covering the full journey from awareness to lead to sign-up to first activation across 21 international markets. You will own both B2B demand generation and inbound seller sign-up, ensuring we attract the right sellers through localised, high-converting experiences, while accelerating speed to first sale.

This includes leading AI-powered digital marketing, trade PR, CRM, content, and funnel optimisation to deliver efficient, scalable growth. This is a tech-savvy, data-driven role, operating across 19+ languages and leveraging AI-powered automation across LinkedIn, email, social, and PR to scale seller acquisition.

You will design and run a repeatable system that delivers predictable lead and sign-up growth, balancing Cost per Lead (CPL) and Cost per Acquisition (CPA) while driving seller quality (lead scoring). This is a critical role that owns the front door of the OnBuy Flywheel, driving continuous storytelling of our growth story and converting that into high-quality inbound seller demand.

You will work closely across Onbuy to accelerate speed to first sale, ensuring outbound acquisition translates into real GMV and contribution. Sellers are the fuel of our Flywheel. You will be the driving force that brings high-quality sellers onto the platform and enables them to start trading at pace.

Through best-in-class demand generation, seamless sign-up experiences, and insight-led optimisation, you will shape how sellers discover, join, and succeed on OnBuy.
