đ± About Mous
We are Mous. (Pronounced mouse, not moose.) People deserve tech and lifestyle products that are fit for purpose, perform as promised, and empower them to be their best. Thatâs why weâre building the go-to brand for products that genuinely deliver.
For over 10 years, weâve pushed product performance to its limits, designing from first principles, validating through real-world testing, and investing millions in R&D. In parallel, weâve built world-class in-house marketing capabilities, creating highly engaging, performance-led content that proves what our products can do and resonates with a passionate, fast-growing community around the brand.
From throwing phones off dams to launching category-defining products, our ambition is simple: raise the standard of the industry and build one of the most effective consumer brands in the world.
đšâđ» About the Role
Weâre looking for a Marketplaces Growth Manager to take ownership of one of Mousâ fastest-growing commercial channels by scaling our global marketplace presence and unlocking the next phase of growth.
Amazon is already a significant growth opportunity for Mous, and this role is about building on that momentum. Youâll own the strategy, performance, and expansion of our marketplace business across 9 markets by identifying opportunities, improving how we operate, and turning insights into measurable commercial impact.
This isnât a role focused purely on marketplace execution. Youâll have the opportunity to shape the direction of the channel, whether that's launching new products, improving profitability, optimising the customer journey, expanding into new markets, or making Prime Day a huge success, you'll be at the centre of it.
Reporting directly to our Head of Commercial and managing our Marketplaces Executive, you'll have the autonomy, visibility, and ownership to make a real impact. As the channel continues to grow, you'll play a key role in shaping the future of the marketplaces function and building a team around it.
đ About YouâŻ

Youâll enjoy working cross-functionally and influencing teams around you, bringing clarity, structure, and momentum to a fast-moving environment. This role is for someone who thrives with autonomy, takes ownership of outcomes, and wants to build rather than simply maintain. Youâll be excited by the chance to help shape the future of Mousâ marketplace growth and play a key role in scaling a global consumer brand.
