Customer Success Engineer – Shifted Week: Tuesday - Saturday

Growth Marketing

• Own the acquisition funnel end-to-end: understand where sign-ups come from, which channels are accelerating or stalling, and why
• Amplify externally what we build internally: turn launches into extended reach without just throwing money at the problem
• Optimize free-to-paid conversion: find the features that drive upgrades, and build the campaigns (drip, in-product, lifecycle) that surface them at the right moment
• Improve our landing pages with real data: get into the weeds of traditional SEO and AI recommendations (AEO/GEO)
• Evaluate paid spend: see how sponsorships, ads, and events affect our distribution. Double down on what works, and consider dropping what doesn't
