Job summary

You will work directly with the CTO and Head of Product to translate complex capabilities into compelling narratives for buyers and users, then test what moves them. This role sits at the intersection of Product, Engineering, Sales, and Growth, shaping messaging, enabling the field, and driving channel experiments.

• Launches: Run product and feature launches end to end. Partner with Product and Engineering on timing and messaging, and make sure Sales and the field are enabled with the narrative, assets, and materials they need on day one.
• Growth & Distribution: Identify and test the channels that reach our audience. Work on activation, onboarding, and conversion messaging, run experiments across the funnel, and double down on what works.
• Customer & Market Insight: Talk to users and customers regularly to understand their needs, objections, and mental models. Track competitors and the broader landscape, and bring those insights back into product and marketing decisions.
