Head of Communications, United States

From your everyday PowerPoint presentations to Hollywood movies, AI will transform the way we create and consume content. Today, people want to watch and listen, not read — both at home and at work. If you’re reading this and nodding, check out our brand video.

Despite the clear preference for video, communication and knowledge sharing in the business environment are still dominated by text, largely because high-quality video production remains complex and challenging to scale—until now…

About the role…

At Synthesia, we are building the future of video communications and collaboration at work. After eight years of research and a roller coaster ride of successes and failures, Synthesia is now the leading AI video platform, with over 65,000 customers, including 80% of the Fortune 100.

We are just getting started in laying the groundwork for a whole new kind of media, and a new company. Imagine joining Airbnb or Stripe when these companies were in their early days. 

We’re hiring a Head of Communications to own our communications strategy across the United States, the company’s largest market. You will set the narrative, build and deepen relationships with tier one media and AI creators/thought leaders, shape launch and product communications, guide executive visibility, and lead issues and crisis response. This is a rare chance to shape the media perception of a category leading AI company at a pivotal moment for the industry.

What you’ll be doing…

• Build the US comms strategy and calendar aligned to company objectives, product roadmap, and commercial milestones, positioning Synthesia as a leader in generative AI and the verticals/markets we operate in 
• Own media relations with top tier business, tech, and policy outlets; drive proactive storytelling, exclusives, briefing programs, and data-driven narratives.
• Executive communications for our CEO and other US-based leadership: speeches, op-eds, bylines, conference keynotes, and social presence; coach executives and manage our speaker and awards pipeline.
• Lead product and launch communications (positioning, messaging, press materials, embargo programs, creator influencer outreach) in close partnership with Product and Marketing.
• Thought leadership and GTM comms: craft timely POVs on the enterprise AI video category and adjacent trends; leverage milestones (e.g., funding rounds, product innovations, customer stories).
• Serve as comms lead for issues and crisis (policy, security, trust & safety), building robust playbooks, training spokespeople, and running red-teaming simulations. 
• Measurement and insight: set KPIs (share of voice, message pull-through, quality of coverage, site traffic lift), run ongoing reporting, and optimize the comms function.
• Responsible AI narrative: communicate Synthesia’s approach to responsible AI, and AI governance work with clarity and transparency. 

What you’ll bring...

• 10+ years in communications with meaningful in-house leadership experience at a high-growth tech company; B2B SaaS and/or AI strongly preferred.
• A proven track record building narratives that land across WSJ, FT, Bloomberg, CNBC, The Information, Forbes, The Verge, Wired or the New York Times, and strong relationships with tech and business reporters, editors and opinion writers at these titles. 
• Experience working with creators and thought leaders in the generative AI space such as Ethan Mollick, Lex Friedman, Tiffany Janzen, Alex Kantrowitz, Casey Newton, Cleo Abram, Lenny Rachitsky, Matt Wolfe, Catherine Goetze (CatGPT) or Jacklyn Dallas (Nothing But Tech)
• Deep experience in issues and crisis communications (policy, safety, and regulatory topics), plus clear instincts on when and how to engage. 
• Exceptional writing: crisp messaging, compelling stories, and executive-ready materials (press notes, op-eds, keynote presentations).
• Strong leadership and experience working with cross-functional teams; comfortable operating with urgency in a dynamic market.

• Put the Customer First
