REP Fitness•Westminster, CO

10d•$175,000 - $200,000•Hybrid

About The Position

Purist Nutrition, a REP brand, is building a modern performance and wellness business for people who care about staying strong, healthy, and active for the long haul. We make premium, science-backed nutrition products using clean ingredients, clinically relevant doses, and rigorous third-party testing. Our goal is simple: create products people can trust and build a brand that helps them keep progressing. Purist is a growing business with big ambitions, backed by the resources and foundation of REP. This is an opportunity to join at an exciting stage and help shape where the brand goes next. This role is based in our state-of-the-art headquarters with a bright, spacious, shared workspace; scenic views of the Rocky Mountains; and a kitchen always stocked with healthy snacks, protein powder, and coffee. We offer a hybrid work environment with a minimum of three days in the office, but there’s flexibility about which days and hours. We’re looking for a Head of Growth to join Purist at the Senior Director level, owning the digital engine behind our next stage of growth. Purist is at a stage where what we build now can materially shape where the company goes next. The Head of Growth will have significant ownership, working closely with leadership across marketing, product, finance, and operations to own the strategy and performance of Purist’s digital business across DTC, Amazon, TikTok Shop, paid media, website conversion, retention, and customer economics. This isn’t simply a paid media role or an e-commerce merchandising role. We’re looking for someone who knows how to build a growth machine. That means a highly analytical, commercially minded digital operator who understands the entire customer journey—from the first ad impression through conversion, repeat purchase, and long-term customer value—and knows how to connect all of those pieces to drive sustainable growth.
