About this role

We’re looking for a hands-on SEO Manager to join our Marketing team and help us strengthen Synthesia’s organic growth engine. This is a role for someone who loves experimentation, automation, and creativity as much as analytics — and who gets excited about building high-quality, high-converting website experiences (UX + CRO) that drive users into product.

What's exciting about this job?

You’ll play a critical role in building the future of Synthesia’s organic growth engine, collaborating with smart, highly motivated peers. You’ll have the freedom to experiment, test bold ideas, and explore how AI and automation are reshaping search optimization. We move fast, value experimentation over theory, and encourage you to break the “SEO rulebook” when it leads to better outcomes.

How will your day-to-day look?

Managing end-to-end SEO initiatives across on-page, technical, and content — with a particular focus on creating outstanding landing pages and journeys that drive users into product. You’ll partner closely with Product, Brand/Design, and Engineering to improve UX, conversion, and performance, while using data and experimentation to continuously iterate. We move very fast and prefer doing > talking.

Strong attention to detail with a solid understanding of UX/UI across both mobile and desktop.
Experience with measurement and reporting tools (Looker, GA4, HubSpot, or other BI tools) and the ability to turn complex data into clear insights.
Self-starter with a strong bias for action, thriving in fast-moving environments where doing > talking.
