• In-depth knowledge of Amazon Seller Central, eBay Seller Hub, marketplace algorithms, and ad platforms

• Confident with Excel, data analysis, and feed management software (e.g. Linnworks, ChannelAdvisor, etc.)
• Commercial thinker who thrives on identifying new product gaps and turning insights into sales
• Excellent communication and problem-solving skills – hands-on, proactive, and results-driven

What will your role look like?

• Own the performance and strategy of all marketplace activity
• Lead sales growth initiatives across Amazon and eBay, including domestic and international expansion into Europe and other high-potential regions

• Identify high-potential product opportunities based on customer demand, competitor analysis, and keyword trends
• Use tools like Helium10, Amazon Ads, and eBay Promoted Listings to optimise listings and maximise visibility
• Monitor daily marketplace performance (traffic, conversion, Buy Box %, ACoS, ROI), and take data-driven actions to improve
• Proactively manage account health, feedback, and policy compliance
• Oversee inventory accuracy, fulfilment strategies, and shipping performance
• Collaborate with customer service and warehouse teams to ensure an excellent post-sale experience and avoid order issues
• Troubleshoot listing issues, handle suppressed or flagged products and maintain compliance with platform policies
• Manage the full marketplace catalogue, including new product setup, bundle creation, and seasonal range planning
• Enhance product listings with strong keyword optimisation, clear descriptions and high-converting visuals
• Work closely with the Head of Sales & Marketing, marketing team and internal stakeholders to align campaigns and drive performance
• Support wider ecommerce initiatives where marketplace insights are valuable (e.g., product demand trends, customer behaviour)

What can you expect in return?

• Join a fast-growing UK brand with strong customer loyalty and repeat sales
• Office-based role in Sheffield (Monday–Friday) with an early finish every Friday
• Real autonomy to shape marketplace growth strategy
• Be part of a friendly, supportive team that values initiative and impact
