Working Pattern: Monday-Friday, 08:45-17:30

Our client is a highly successful and rapidly growing UK retail business with an established nationwide presence and an exciting e-commerce operation. As their Marketplace continues to expand, they are looking for a New Business Onboarding Executive to join their team in London. This is an excellent opportunity for someone at the beginning of their career who is passionate about e-commerce, online marketplaces and delivering an exceptional seller experience.

You'll play a key role in bringing new sellers onto the Marketplace, supporting them through the onboarding journey and helping them establish a strong foundation for long-term success. Working closely with the New Business Lead, Seller Account Management team and wider internal departments, you'll become an important point of contact for new sellers, guiding them through systems, product listings, compliance, processes and marketplace best practice.

What You'll Be Doing

• Guide new sellers through the Marketplace onboarding process, including systems, tools, policies and operational requirements.
• Work alongside the New Business Lead to conduct seller vetting and in-house compliance checks.
• Ensure new sellers meet relevant legal, regulatory and company requirements throughout the onboarding process.
• Help identify, prioritise and progress high-value new seller opportunities in line with wider business objectives.
• Provide dedicated support to sellers throughout their sign-up and introductory period.
• Assist sellers with product listings, optimisation and ensuring logistical requirements are successfully met.
• Troubleshoot and resolve seller queries relating to account setup, product listings, operational processes and Marketplace integration.
• Work collaboratively with internal technical and operational teams to resolve and escalate issues where required.
• Support new sellers throughout their first 4-6 months, monitoring progress and KPIs and helping them build towards long-term success.
• Work with external partners to support accurate and timely product onboarding.
• Deliver training and onboarding sessions to new sellers, ensuring they understand the systems and processes required to operate successfully.
• Manage seller enquiries through Zendesk, providing timely, professional and customer-focused communication.
• Work closely with Seller Account Management, Finance, Marketing, Compliance and other teams to resolve issues and improve the overall seller and customer experience.
• Produce and analyse regular reports to monitor performance and support decision-making.
• Support the successful handover of sellers from the onboarding phase to the wider Seller Account Management team, ensuring key information and performance indicators are clearly communicated.

What We're Looking For

This role would suit someone who is early in their career and keen to build a career within e-commerce, marketplaces or account management. You may have 0-2 years' experience, or have developed relevant skills through university, internships, placements, customer service or similar experience.

• A genuine interest in e-commerce and online marketplaces.
• Excellent communication and interpersonal skills.
• A strong customer-service mindset and a proactive approach to problem solving.
• Excellent attention to detail and the ability to work accurately.
• The ability to manage multiple priorities and work effectively to deadlines.
• Confidence using Microsoft Excel, including formulas and graphs.
• An organised, professional and collaborative approach.
• The ability to work effectively with technical, operational and commercial teams.
• Familiarity with product listings, seller platforms or marketplace tools would be advantageous, but isn't essential.
• A willingness to learn, take ownership and build strong relationships with sellers.

Why Join?

This is a fantastic opportunity to join a high-growth e-commerce and marketplace environment where you'll have genuine responsibility from day one. You'll gain exposure to a broad range of commercial, operational and technical areas while working directly with new businesses and helping them successfully establish themselves on a growing Marketplace. If you're organised, commercially curious, confident working with people and looking to develop your career in e-commerce and marketplace operations, this could be an excellent next step.
