Should a product marketing team have a growth product marketer? If so, when, and what should we think about their focus and scope of work?

If there’s a Growth Product & Engineering team that has enough work to support a growth product marketer, then I’d say it makes sense. Their work and scope should be closely mapped to the roadmap of the Growth Product team. Typically will be focused on experiments to improve core user metrics through product adoption, rather than big GTMs / product launches.
