About the position:
We’re looking for a Senior Growth Content Marketing Manager to own performance messaging end-to-end, from insight and concept through execution and iteration.
This is a maternity leave replacement role for a period of six months, with an option to extend.
This role is responsible for developing Lumen’s messaging framework and delivering high-performing copy that drives lead generation and conversion across ads, emails, landing pages, and partner marketing assets. You will shape and evolve positioning for weight loss and GLP-1 audiences, translating insights, strategy, and performance data into clear, compelling messaging that can be deployed and iterated at scale.
This is a hands-on role that requires strategic thinking, strong execution, and use of AI to scale both the quality and quantity of performance content. You will have direct ownership of copy quality, consistency, and iteration, and operate as a core partner to Acquisition, Lifecycle, CRO, and Partnerships.
Responsibilities
Own messaging across paid ads, emails, landing pages, and partner marketing assets

Design and use AI-powered workflows to accelerate ideation, variation, versioning, and iteration of copy while maintaining quality

Iterate copy based on performance feedback and clearly connect changes to outcomes
Create partner-ready copy for co-branded assets, landing pages, emails, and enablement materials

Experience writing high-performing copy for ads, emails, and landing pages
Strong understanding of performance marketing funnels, hooks, and conversion psychology
Experience developing and maintaining messaging frameworks
Demonstrated experience using AI tools to materially increase copy output, speed, or testing velocity, not just for brainstorming
Proven ability to design prompt frameworks, templates, or AI workflows to support iteration and experimentation
Comfortable operating in fast-paced, high-iteration environments
Strong cross-functional collaboration and communication skills
Experience using AI tools to increase speed and scale without compromising quality
