Marketplace Seller (E-commerce)

Job Description

About this role

Are you a commercially minded relationship builder who thrives in the fast-paced world of e-commerce? This role offers fantastic exposure and represents an excellent step up from a junior position.

As our Marketplace Seller, you will own the end-to-end performance lifecycle of Yimbly’s diverse seller base. Your mission is to bridge the gap between seller potential and retail reality, driving incremental revenue while ensuring our marketplace remains a gold standard for quality and compliance.

Reporting directly to the Head of Trading & Products, you will be the central commercial point of contact for our sellers. You’ll act as a strategic partner, translating high-level trading priorities into SKU-level action plans that benefit our customers, our sellers, and the Yimbly brand.

What you’ll do

You’ll be at the heart of our trading operations, balancing strategic growth with operational excellence. Your key responsibilities include:

• Strategic Seller Development: Oversee post-onboarding development by maintaining and reviewing structured Joint Business Plans (JBPs) to drive sustainable growth and tier progression on a monthly basis.
• Retail Media & Commercial Revenue: Drive incremental revenue by identifying, packaging, and monetising seller-facing opportunities across retail media, data, and other commercial initiatives.
• Portfolio & Success Playbook: Develop strategies for channel optimisation and seller retention while continuously refining the seller playbook and training materials to streamline operations.
• Trading Coordination: To ensure high-potential deals are integrated into the master trading calendar, you will supply the Trading team with weekly and monthly seller offers at the SKU level. You will lead seller negotiations to enhance pricing, margin, funding, or exclusivity to ensure deals are commercially viable and competitive.
• B2B Communications: Own and Lead all seller communications regarding seasonal campaigns promotions as well as including service messaging to ensure high engagement and participation in site-wide events.
• Performance & Compliance: Monitor performance to ensure strict compliance with marketplace policies, SLAs, and regulatory standards, including tax and safety.
• Listing Excellence: Collaborate with sellers to optimise product listings for "Retail Readiness," ensuring high-quality images and descriptions in sellership with the Marketplace Admin team.
• Audit & Intervention: Conduct regular reviews to identify underperforming sellers for either structured recovery plans or offboarding.
• Data & Dispute Resolution: Use performance analytics to identify growth opportunities or gaps and mediate seller-related inquiries and disputes to protect brand reputation.

Qualifications

What you need to succeed

• Marketplace Savvy: You already know your way around platforms like Mirakl or Shopify, and you understand the fundamentals of marketplace compliance (SLA, tax, and safety).

• Data-Driven Commercial Acumen: You can manipulate data in Google Sheets to spot trends, diagnose performance gaps, and unlock revenue-driving opportunities (like Retail Media).

• Top-Tier Communication: You love building B2B relationships, confidently pitching ideas using Google Slides/PowerPoint, and bring a professional, "camera-on" presence to every meeting.

• The Growth Mindset: You thrive in a fast-paced environment, possess the creative imagination to spot new retail opportunities, and have the drive to hit growth targets.
