LaunchWave is looking for a hands-on Marketplace Growth Manager to drive growth across our key marketplaces - primarily Amazon, Walmart Marketplace and TikTok Shop.

We already have Product/R&D, Brand/Creative and marketplace operations expertise.
We now need someone who can turn strong products and customer/brand insights into profitable marketplace growth.

What You'll Do

• develop growth strategies for existing and new marketplace products;
• analyze categories, competitors, search behaviour, reviews, customer behaviour and marketplace data;
• work with the Brand team to identify priority customer segments, use cases and commercial angles;
• develop and test growth hypotheses;
• test pricing, bundles, promotions, offers and messaging angles;
• prioritize marketplaces and growth levers by product;
• diagnose bottlenecks across traffic, CTR, ranking, listing conversion, reviews, pricing and advertising;
• work with Brand/Creative on marketplace creatives, UGC, video and listing assets;
• launch controlled growth experiments and define KPIs/economics for each hypothesis;

• pricing, coupons, deals, promotions and product launches;

• ACOS / TACOS / ROAS;
• inventory impact on growth, marketplace fees and contribution economics

You should be able to look at a specific ASIN and explain why it is selling at its current level, where the bottleneck is, and what should be tested next.

The goal is not simply to list products on Walmart, but to build a profitable growth model through category/competitor analysis, listing/search optimization, Walmart Connect, paid traffic, pricing/promotions, reviews, conversion and marketplace economics.
