We’re also a community that believes fitness is a flip-the-switch trigger for becoming the woman you want to be. Leggings and sports bras won’t change the world on their own. But with a grab-my-hand, let’s-go-for-it-now spirit, the women who wear them can.
If you want to join us on the next chapter of our adventure, you’re in the right place. This is an exciting opportunity to join us as a Media Effectiveness Manager.
Our Values
WE REALLY CARE ∙ FIRST, BEST, BRAVEST ∙ OUR STRENGTH IS IN EACH OTHER ∙ STAND UP, SPEAK UP, SHOUT OUT
About the Role

You will partner closely with channel specialists, analytics, our attribution partner, and CRO to optimise spend, shape our measurement roadmap, and rigorously evaluate incrementality across channels.
This is an exciting opportunity for someone who thrives at the intersection of data, strategy, experimentation, and cross‑functional collaboration.

- Rapidly iterate on creative, messaging, and audience strategies to continually improve performance.
- Explore high-impact offline media opportunities to diversify the acquisition mix and drive incremental reach.
- Establish KPIs for new channels and ensure reporting clarity across stakeholders.

Our DEI Commitment
We are working to create a culture and team that represents our mission of empowerment. We want to celebrate our diversity, embody inclusion and create an equitable business. This means doing more and working harder to make the long-lasting changes necessary. We care about our people, our community and world.
We want to stand up for what we believe in and give our people a platform to use their voice. To actively listen and learn from what they have to say. This involves focusing on learning, development, and progression across the business. Being clear on the responsibilities we hold each other and to our community. It also means being committed to equal employment opportunities. Ensuring we consider ALL applicants for jobs and working harder to make our job advertising more inclusive.
Our DEI mission is "to embed diversity, equity and inclusion at the heart of our business. To create a culture of belonging that empowers everyone to be their best authentic self. We commit to celebrating different perspectives and to continuously learning, developing and challenging ourselves and our partners."
We know we're on a journey. And far from perfect. But we want to be a part of the solution to the problem. It might not be comfortable or straightforward. But if we weren't up for doing the hard work and breaking the mould, we wouldn't be Sweaty Betty. We are committed to working across our business and with our DEI committee & DEI Collective to be champions, allies and inclusive, always. Because when we say all, we mean it.
