About the Role GlossGenius is expanding into larger, multi-location service businesses and the go-to-market strategy for this segment is still being built. As Senior Product Marketing Manager for Upmarket, you'll own that build, from customer discovery and ICP definition through positioning, launch, and ongoing iteration. You'll be the connective tissue across Marketing, Creative, Product, Sales, Growth, and Strat Ops, and the internal voice of the upmarket customer on everything from roadmap decisions to sales collateral. This isn't a role where the playbook exists and you execute it. The segment is emerging, the motion is evolving, and the person who succeeds here will have written the approach from scratch. You will report to the Senior Director of Product Marketing. You must be commutable to our NYC headquarters and will operate in an in-person environment. We default to being in-office 3–4 days per week with required attendance on Tuesdays and Thursdays.
