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, this is the perfect career upgrade for you.

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:
