Growth Copywriter

Sans is on a mission to build the next great consumer hardware brand, with a laser focus on products that help people live healthier lives at home. We started with a category-leading air purifier before expanding to a best-in-class countertop water purifier that actually works to eliminate harmful contaminants – and our product roadmap is just getting started.

We’re a small, ambitious team that believes deeply in our ability to create a meaningful consumer brand. We move fast, learn quickly, and consistently outperform much larger competitors.

The Growth team plays a critical role in driving customer acquisition, revenue, and scalable growth across channels. This team is accountable for developing and optimizing performance marketing strategies, creative, and experimentation frameworks to efficiently reach new customers and expand our impact as we grow.

The Growth Copywriter will support the execution layer of our creative operation across paid ads and other channels, with a strong emphasis on writing high-performing copy. They will contribute to concepts, hooks, and scripts while helping coordinate their execution. The role reports directly to the Creative Strategist and will work closely with our Video Editor, Digital Designer, agency partners, and freelance creators. They will also collaborate with the broader Sans team to help write and refine copy across direct-response channels like email & lifecycle, web & landing pages, and more.

The ideal candidate brings strong instincts for direct-response copy and ads and is hands-on with writing across formats. They should be comfortable analyzing performance to understand what’s working and what’s not, and bring a scrappy, proactive mindset.
