Job description

Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US.

As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations.

Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, Nvidia’s VC arm, Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow.

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.

Location

London (~3 days per week in office)

Imagine joining Airbnb, Stripe, or Figma — when they had product‑market fit, but the world hadn’t completely realized it yet. That’s how early we are.

Requirements

• 5+ years of experience in SEO, with strong on‑page and technical foundations.
• Strong UX + CRO instincts, with experience improving website journeys (copy, interaction patterns, information architecture) to increase conversion.
• AI‑native operator. You do the work in Claude or your AI tool of choice. You’re able to automate workflows to ship faster and scale output without sacrificing quality.
• Track record of shipping high‑quality landing pages that combine SEO best practices with product marketing and clear conversion paths into product.
• Comfortable partnering cross‑functionally with Product, Design, and Engineering to scope, ship, and iterate on website improvements.
• Skilled in auditing and optimizing localized websites, improving performance and visibility across multi‑language and geo‑specific markets.
• 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.
• Bonus: experience with off‑site SEO and driving performance in AI search
• Curious, adaptable, and deeply interested in how AI is transforming search — eager to experiment with new discovery channels, test what drives results, and push the boundaries of what SEO can achieve.
