About The Position

As a Senior Designer on the Growth Creative team, you’ll lead the execution of high-performing design across static ads, landing pages, and print assets. You’ll collaborate closely with the Creative Director, strategists, and channel managers to develop work that drives business results across platforms and channels. As a senior member of the team, you’ll contribute to creative development by helping ideate and brief new concepts across channels. You’ll partner with creative collaborators (like video editors and content creators) to bring those ideas to life — including supporting content capture when necessary, from filming assets to sampling products. You’ll collaborate with channel managers to understand how your creative is performing, and support creative team members and freelancers to maintain quality and consistency across deliverables.

You’re confident in formatting for different platforms (1:1, 4:5, 9:16) and understanding visual needs across funnel stages
You bring expertise in AI workflow integration and are excited to innovate with emerging tools — using AI to enhance strategy, storytelling, and efficiency while maintaining human creative quality
You’re skilled at optimizing landing pages for conversion and enjoy translating briefs and data into clean, conversion-minded design work
You’re a collaborative teammate who communicates clearly and works well across functions
You’re adaptable and curious, eager to explore new tools and trends in a rapidly evolving digital and AI landscape
You’re proactive, reliable, and detail-oriented, able to deliver high-quality creative across multiple workstreams

Nice To Haves

Ability to design for motion (video or GIF) assets is nice to have, but not required

Integrate AI workflows into the design process, using tools like Figma, Photoshop, and emerging MarTech platforms to streamline concepting, production, and iteration
