Your Mission

As Senior Product Manager - Seller Excellence, you will shape how sellers succeed on Catawiki by improving the end-to-end seller experience, from submission to ongoing performance on the platform. Your mission is to make it easier for sellers to operate effectively, unlock more value from Catawiki, and contribute to a stronger, healthier marketplace. This role sits at the intersection of seller experience, commercial impact, and operational excellence, with a clear focus on outcomes that matter for both sellers and the business.

A key part of your scope will be identifying how AI can meaningfully improve the seller journey and the way internal teams support sellers. You will help define and deliver AI-powered experiences for sellers and internal experts, while also building product mechanisms that encourage better seller behaviour in areas such as shipping performance, responsiveness, and cost efficiency. Through strong product judgment, cross-functional collaboration, and a sharp focus on measurable impact, you will turn complex marketplace challenges into clear product priorities and scalable solutions.

What You’ll Do

In this role, you will own a strategic product area focused on helping sellers perform better on Catawiki and enabling the business to scale seller excellence more effectively. You will work across discovery, strategy, execution, and optimisation, partnering closely with engineering, design, data, and commercial stakeholders to identify the right problems to solve and deliver meaningful results.

Define and drive the product strategy for seller excellence, focusing on improving how sellers submit, manage, and optimise their performance on the platform.
Build AI-powered co-pilot experiences that help sellers identify opportunities, improve submissions, and increase their success on Catawiki.
Develop AI-enabled tools for internal experts to improve efficiency, consistency, and effectiveness in seller-related workflows.
Design and implement product mechanisms that influence seller behaviour, including incentives and feedback loops related to shipping time, shipping cost, cancellations, and responsiveness.

What You’ll Bring

You bring strong product fundamentals, sound judgment, and the ability to operate effectively in a complex marketplace environment. You know how to work across multiple stakeholders, connect business needs to product decisions, and focus teams on the work that will create the most impact. You are comfortable balancing strategic thinking with hands-on execution, and you communicate clearly across technical and non-technical audiences.

5 to 10 years of product management experience, with senior-level ownership of product direction, prioritisation, and delivery.
Experience in marketplaces or platform businesses involving sellers, vendors, or service providers, with a strong B2B mindset.
