Marketplace Manager (Amazon)
Brand: Bettervits

Type: Full-Time
Start Date: ASAP
About Us
Bettervits is one of the fastest-growing nutrition brands in the UK, having served over 1 million customers in just a few years. We combine premium products with strong expertise in e-commerce and performance marketing, and we’re growing across DTC, Amazon and retail.
We’re looking for an experienced Marketplace Manager to lead Amazon growth at Bettervits. You’ll own the channel’s trading plan, revenue and contribution margin, and work with the wider team to grow our existing range and launch new products.
This is a hands-on role for someone who has already scaled a sizeable Amazon business. You’ll be comfortable setting the quarterly plan, getting into Seller Central to diagnose why a listing has stopped converting, and making the call on how much to spend on ads or promotions.
What You’ll Be Responsible For
Own Amazon’s growth plan, sales forecast and channel P&L. Track contribution margin after advertising, Amazon fees, fulfilment, promotions and returns.
Manage day-to-day trading across the range, including pricing, promotions, deal planning and stock availability. Build the calendar for Prime Day, Black Friday and key seasonal periods.
Improve organic visibility and conversion through keyword research, listing copy, imagery, A+ Content, Brand Stores and structured testing. Monitor ratings, reviews and returns for issues that need action.
Own Amazon Ads strategy and performance across Sponsored Products, Sponsored Brands and Sponsored Display. Set budgets and targets by SKU, and use TACoS, organic sales and contribution margin to judge when to scale spend.
Lead new product launches from listing setup and stock planning through to advertising and post-launch trading. Set clear targets for sales, conversion and profitability.
Work with supply chain and finance to forecast demand, manage FBA inventory and prevent stockouts, excess stock and avoidable fees.
Own account health and resolve listing suppressions, catalogue issues and compliance requests. Work with the product and regulatory teams to keep supplement listings and claims compliant.
Report weekly on what moved sales and margin, where the biggest opportunities are, and what you’re doing about them.
What We’re Looking For
Senior-level experience owning and scaling an Amazon channel for a consumer brand, with clear examples of growing revenue while maintaining or improving profitability.
Deep, hands-on knowledge of Amazon Seller Central, FBA, Brand Registry, Amazon Ads and catalogue management.
Strong commercial judgement. You understand how pricing, promotions, ad spend, Amazon fees and stock availability affect SKU-level profitability.
A track record of improving organic ranking and conversion, turning around underperforming listings and launching new products on Amazon.
Confidence using Amazon Brand Analytics, Search Query Performance and advertising reports to identify what’s driving performance and decide where to invest.
Experience setting priorities across creative, paid media, finance and supply chain, with the ability to execute independently.
Bonus
Experience in supplements, nutrition, wellness or other repeat-purchase categories.
Experience scaling on Amazon US or expanding into additional Amazon marketplaces.
Familiarity with Vendor Central, Amazon DSP or Amazon Marketing Cloud.
Experience with Subscribe & Save and using repeat-purchase data to inform acquisition and promotions.
Why Join Us?
Competitive compensation package with performance-based incentives.
Ownership of a major growth channel at one of the UK’s fastest-growing nutrition brands.
The budget and cross-functional support to improve the existing range and launch new products.
Autonomy to set the Amazon plan, with direct access to founders and decision-makers.
A fully remote role with scope to take on more responsibility as the marketplace business grows.
