About our client

Zero Longevity Science is the world's leading fasting app, with over 10 million users on a journey toward better metabolic health. The company is now building a powerful new AI-forward product that lives alongside Zero—and is looking for a seasoned Product Marketing Manager to help bring it to life.

Zero has a massive audience and a trusted brand. With this new product, the company is entering an exciting next chapter—where AI, coaching, and metabolic health intersect. Candidates who love creating launch moments, scaling up from early traction, and storytelling with impact are encouraged to apply.

This is a high-impact, part-time contract role (40 hrs/week) that places the selected candidate at the intersection of product, marketing, and growth. The role will involve partnering directly with the CEO and a small but mighty team to shape and lead go-to-market efforts for the upcoming launch—while also supporting core marketing activities across the existing Zero product.
