At Argos, our Marketplace is a growing part of how we show up for customers, bringing together more choice, more sellers and more ways to shop. Behind that is a Marketplace team focused on getting sellers set up for success from day one.

The Seller Onboarding Assistant sits right at the centre of that journey, shaping how new sellers join, launch and start trading on the platform.

Working across Marketplace, technical and commercial teams, the role brings together data, systems and seller engagement. From managing integrations and supporting catalogue setup to tracking onboarding progress, the focus is on delivering a smooth, well managed experience that works for both sellers and customers.

It’s a fast-moving role with real variety, ideal for someone with experience in eCommerce or marketplace operations who understands the importance of data quality, seller management and getting the detail right.

What You’ll Do The role owns the end-to-end onboarding journey for new Marketplace sellers, ensuring everything is in place for a smooth and successful go live. This includes supporting sellers through account setup, from configuring their store and policies to ensuring VAT and operational details are aligned with business standards.

Working closely with technical teams, the role coordinates integrations such as APIs and feed uploads, as well as supporting order management testing. There is also a strong focus on product catalogue setup, ensuring listings meet data quality, taxonomy and content standards from the outset.

A big part of the role is keeping things moving. That means spotting onboarding challenges early, resolving issues where possible and escalating where needed. Alongside this, there is regular communication with internal teams to keep everyone aligned on seller readiness, timelines and any key risks.

The role also plays a part in improving how onboarding works day to day, identifying opportunities to make the process simpler, faster and more consistent. Throughout it all, building strong relationships with sellers is key, ensuring they feel supported and confident as they launch on the platform.

Who We’re Looking For This role would suit someone who has experience working in eCommerce or marketplace operations and understands what good looks like when it comes to onboarding sellers and managing product data.

A strong level of organisation is important, along with the ability to manage multiple onboarding journeys at once in a fast-paced environment. Confidence working with systems, integrations and data is key, as is a naturally detail focused approach.

Clear communication also plays a big role, working with a range of external sellers as well as internal stakeholders across technical and commercial teams. A proactive, solutions focused mindset will help in navigating challenges and keeping onboarding on track.
