Senior Growth Marketing Manager

Senior Growth Marketing Manager

Remote (U.S.) | Full-Time

Build the Future of Biotech Beauty

At SickScience, we're not another skincare brand.

We're a biotechnology skincare company transforming beauty through our proprietary plant-derived exosome platform. Backed by years of regenerative medicine research, our clinically validated products are now available nationwide at Ulta Beauty, growing rapidly on Amazon, and sold directly through our Shopify store.

We're building one of the most science-driven brands in beauty—and we're looking for an exceptional marketer to help shape what comes next.

This isn't a traditional corporate marketing role. It's an opportunity to own growth, move fast, experiment often, and work directly with the founders to scale one of the industry's most innovative beauty brands.

About the Role

We're looking for a highly analytical, hands-on Senior Growth Marketing Manager who understands how modern consumer brands scale.

You'll own the digital growth engine across paid media, ecommerce, CRM, analytics, marketplaces, and conversion optimization.

This is not a role for someone who simply manages agencies or reports on performance. We're looking for a builder—someone who enjoys testing ideas, solving problems, making data-driven decisions, and driving measurable business growth.

You'll have the autonomy to experiment, optimize, and build scalable systems that directly impact revenue.

Why Join SickScience?

You'll work directly with the founders and play a key role in shaping the future of the company.

At SickScience, we move fast. We're looking for someone who enjoys taking ownership, making decisions, and turning ideas into action without layers of bureaucracy.

You'll have the opportunity to make meaningful decisions, test bold ideas, and see the direct impact of your work.

We're building more than a skincare brand—we're building a science-driven company that's redefining what beauty can be.

One More Thing..

We care far more about what you've built than where you've worked.

If you've helped grow a brand through smart execution, relentless testing, and data-driven decision-making, we encourage you to apply. We value curiosity, ownership, and a builder's mindset above big-company titles.
