E-commerce Account Manager (Marketplaces)

About the Role

Numan is on a mission to transform health. To do that, we need to meet our customers where they are. We’ve built a powerful direct-to-consumer brand, and now we are ready to massively scale our footprint across online marketplaces—specifically dominating Amazon (UK & Europe) and TikTok Shop.

We aren't looking for a passive backend operator who just pushes buttons and tweaks keyword bids in isolation. We are looking for a commercial business owner.

As our Marketplace Manager, you will hold the keys to a vital growth engine for Numan. You will be the bridge between complex marketplace algorithms and our internal leadership team, translating data into clear growth strategies, collaborating cross-functionally, and leading our expansion into European markets.

If you are currently juggling 5–10 demanding e-commerce clients and want to move in-house to focus deeply on scaling a single, high-growth brand with a healthy budget.

You'll be:

• Owning the Commercial Strategy: Take complete end-to-end accountability for Numan's P&L across Amazon (Seller & Vendor Central) and TikTok Shop, driving revenue while maintaining strict efficiency metrics (ROAS/ACOS).
• Driving European Expansion: Act as the project lead for our upcoming launch into Europe (e.g., Germany, France), navigating international compliance, localization, and supply chain logistics.
• Translating Data Into Action: You won't just look at spreadsheets; you will regularly present performance updates, channel insights, and strategic forecasts to non-technical stakeholders and company leadership.
• Collaborating Cross-Functionally: Partner daily with our Supply Chain, Product, Creative, and Growth Marketing teams to ensure inventory alignment, seamless product launches, and cohesive brand messaging.
• Optimising Technical Execution: Oversee the technical health of our stores, managing listing optimization, A+ content, catalog troubleshooting, and deep-dive PPC campaign architecture.

We're looking for someone who has:

• Proven Marketplace Expertise: 3+ years of hands-on experience managing and scaling Amazon accounts (Seller Central is non-negotiable; Vendor Central is a strong plus).
• TikTok Shop Experience: Practical experience launching, managing, or optimizing TikTok Shop operations and creator-led commerce.
• Exceptional Communication Skills: You have a proven ability to break down complex digital marketing or marketplace metrics into clear, structured, and persuasive arguments for internal stakeholders or clients.
• An Agency or High-Growth Background: Experience working in a client-facing digital agency or a fast-paced DTC scale-up where proactive communication and managing competing priorities was daily protocol.
• Analytical Polish: Advanced Excel skills and an ability to look past the "vanity metrics" to diagnose the root cause of an underperforming campaign or catalog issue.
• International Footprint: Prior experience launching or managing brands across European marketplaces (Pan-EU framework) is highly desirable.

It's a bonus if you have:

Experience with international marketplace entry, including navigating regional operational or regulatory differences.

Familiarity with alternative emerging marketplaces like TikTok Shop.

Experience working with specialized external eCommerce analytics or marketplace management software.
