Retention Manager
London, England, United Kingdom Full-time Posted 2 hours ago
📱 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. That’s why we’re building the go-to brand for products that genuinely deliver.
For over 10 years, we’ve pushed product performance to its limits, designing from first principles, validating through real-world testing, and investing millions in R&D. In parallel, we’ve 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.
👨💻 About the Role
We’re looking for a Retention Manager to own and accelerate one of the biggest growth opportunities at Mous.
This is a high-impact role where you’ll take ownership of retention end-to-end by shaping the strategy, building the roadmap, and maximising the value of our growing customer base. You’ll be joining an established, fast-growing DTC brand with a loyal global community, a strong creative identity, and huge potential to deepen customer relationships.
Retention at Mous is a key growth lever. We already have a large and engaged customer base, but there is a significant opportunity to increase repeat purchases, strengthen loyalty, and unlock more lifetime value. From CRM and loyalty through to the full customer journey, you’ll own initiatives that directly influence commercial results.
With a passionate customer base and multiple product categories, the opportunity is huge. You’ll have the autonomy, visibility, and support to become the retention expert in the business and build a best-in-class approach from the ground up.
👋 About You
You’re a commercially minded, data-driven marketer who is excited by the opportunity to turn insights into growth. Being commercial and analytical is essential, but just as important is your ability to generate ideas for testing, whether that’s copy, imagery, or cohorts. With an entrepreneurial and impact-driven mindset, you would actively shape performance through experimentation and iteration, analysing the data to inform the ongoing strategy and plans.
You’ll ideally have experience within DTC or consumer-based brands and understand how retention fits into the wider commercial engine. You know how to define what good looks like through building clear reporting structures, setting meaningful success, and ensuring the team has visibility on performance.
You bring a structured, hypothesis-led approach to improvement. You’re confident building testing frameworks that turn ideas into experiments, and experiments into scalable learnings that improve customer engagement and long-term value.
As the owner of retention at Mous, you’ll be hungry to evolve what already exists, bringing fresh thinking, analytical rigour, and a strong commercial mindset to help unlock the next phase of customer growth.
