Job description

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.

We’re on a mission to make video easy for everyone. Born in an AI lab, our AI video communications platform simplifies the entire video production process, making it easy for anyone, regardless of skill level, to create, collaborate, and share high-quality videos. Whether it’s for delivering essential training to employees and customers or marketing products and services, Synthesia enables large organizations to communicate and share knowledge through video quickly and efficiently. We’re trusted by leading brands such as Heineken, Zoom, Xerox, McDonald’s and more. Read stories from happy customers and what 1,200+ people say on G2.

In 2023, we were one of 7 European companies to reach unicorn status. In February 2024, G2 named us the fastest growing company in the world. In 2025 we announced our Series D funding. In total we’ve raised over $330M from top-tier investors, including NEA, Atlassian Ventures, WiL, PSP Growth, and existing investors such as Accel, Nvidia, Kleiner Perkins, GV and top founders and operators including Stripe, Datadog, Miro, Webflow, and Facebook.

About the role

You’ll join the Content and Community team at Synthesia, leading a Social Media team of one and working very closely with our Creative team to produce impactful social media assets and campaigns.

You are someone who has a deep understanding of social media, content creation, and cultural and tech/AI trends. You live on the For You Pages and come with a great track record of creating real impact on X, Instagram and LinkedIn. You love creating content that engages, entertains, drives action and are used to balancing organizational skills, creativity and excellent communication skills.

What you’ll do

• Fully own distribution across Social Media, deeply understand the latest format trends, best practices and constantly look for growth hacks across platforms to grow reach and impact
  • Manage Synthesia’s day‑to‑day Social Media presence hands‑on (X, Instagram, LinkedIn, TikTok) and lead the social media team.
• Work closely with the Creative team on SoMe assets and campaigns (e.g. hero visuals, video concepts, cross‑channel launches)
• Analyze performance, test new formats, and continuously optimize based on data and insights
• Jump on real‑time buzz opportunities, news cycles, and conversations that matter in AI, tech, and culture and insert Synthesia in meaningful and relevant trends
• Collaborate with product marketing, comms, and growth teams to ensure social supports launches and GTM plays
• Drive employee advocacy, help with Founder brands by enabling teams and individuals to share and amplify Synthesia across their networks

You have

• 4–10 years social media experience at major brand or organization, including at least 2–3 years of management experience
• Proven track record of growing social communities and making a real impact, not just posting content
• Creative portfolio showcasing work that resonates in culture and articulates clear concepts
• Ability to work in high‑level content strategy and hands‑on social media management tasks with extreme attention to detail
• Experience of leading video based social campaigns
• Strong collaboration skills and the ability to build trust, influence partners, and inspire teams

Exceptional candidates will have

• Hands on experience with crafting viral posts and campaigns on X, IG and/or LinkedIn
• Intrinsic interest and motivation to learn more about AI and AI video
