This role will own the Seller Success and Seller Experience roadmap, helping make it faster and easier for merchants to join, integrate with and grow on the marketplace.

You will inherit a clear roadmap and work closely with Product, Engineering, Design and commercial stakeholders to refine priorities and deliver meaningful improvements for sellers.

This is a hands-on Product role for someone who can quickly understand an established platform, build strong stakeholder relationships and turn known opportunities into well-defined, valuable outcomes.

• Product requirements for seller integrations, APIs and connected platform capabilities.
• Prioritisation and delivery across Product, Engineering, Design, Operations and commercial teams.
• Measurement of seller outcomes, including onboarding speed, activation, adoption and seller performance.

What You’ll Be Working On

The marketplace is focused on attracting more high-quality sellers, getting them successfully onboarded and helping them perform once they are live.

You may work on opportunities such as:

• Simplifying merchant onboarding and reducing the time it takes a seller to go live.
• Improving seller registration, verification, catalogue setup and activation journeys.
• Strengthening the Seller Portal and merchant self-service experience.
• Making seller integrations and APIs easier to implement and support.
• Improving the tools and workflows used to manage seller performance.
• Helping sellers understand how to improve their range, availability and sales.
• Identifying friction across the end-to-end seller journey and prioritising the highest-value improvements.

You will be an experienced Product Manager who is comfortable joining an established team, inheriting an existing roadmap and creating momentum quickly.

Ideally, you will bring:

• Product Management experience within a marketplace, eCommerce, retail, SaaS or platform environment.
• Experience owning merchant, seller, supplier or B2B customer journeys.
• Strong knowledge of onboarding, activation, self-service and customer experience.
• The ability to work with Engineering teams on APIs, integrations and technically complex platform capabilities.
• Strong discovery, prioritisation, roadmap management and delivery skills.
• Confidence working with senior stakeholders across commercial, operational and technology teams.
• A practical, outcomes-focused approach and the ability to operate effectively within an existing strategy.
• Strong communication skills and the ability to bring clarity across multiple teams and competing priorities.

Experience in marketplace seller tooling, merchant portals, catalogue management, payments, fulfilment or seller performance would be highly regarded.

What Success Looks Like

You will help the team deliver an established roadmap while continuously refining it through seller insight, data and stakeholder input.

Success will mean reducing friction for merchants, accelerating seller onboarding and activation, improving the seller experience and enabling more sellers to perform successfully on the platform.

Why Join?

• Own a meaningful Seller Success roadmap within a large-scale marketplace.
• Work on complex Product challenges across seller experience, integrations and platform capabilities.
• Join an experienced, collaborative Product team with a clear roadmap and strong business support.
• Make a measurable impact on how quickly sellers can join, activate and grow.
