Welcome to the video first world

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. This is true 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.

Meet Synthesia

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 everyone, 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 February 2024, G2 named us as the fastest growing company in the world. Today, we're at a $2.1bn valuation and we recently raised our Series D. This brings our total funding to over $330M from top-tier investors, including Accel, Nvidia, Kleiner Perkins, Google and top founders and operators including Stripe, Datadog, Miro, Webflow, and Facebook.

The Role

We’re hiring a Technical Associate to support our Chief Technology Officer (CTO) in scaling our technical organization. This is a high-impact generalist role, modeled after the Technical Assistant position Amazon uses to accelerate senior leadership.

You’ll operate as a Chief of Staff for all things technical, partnering with the CTO and working across Product, Engineering, R&D, Design, Data, and Growth. You’ll be responsible for driving key initiatives, managing high-priority projects, and serving as a strategic connector across teams.

This is not an admin role. You’ll be in the room where big decisions get made and expected to influence them. You’ll help the CTO (https://www.linkedin.com/in/powder8/) stay focused, informed, and effective and you’ll multiply the output of the org.

What You’ll Do

• Drive Strategic Projects: Take ownership of ambiguous, high-leverage projects that span product, tech, and operations.
• Support CTO Decision-Making: Bring clarity, context, and structure to technical and strategic conversations.
• Orchestrate Cross-Functional Execution: Keep the trains running across product, engineering, data, and research initiatives.
• Communicate Clearly: Write internal strategy docs, synthesize technical inputs, and help prep comms for leadership and board-level discussions.
• Influence Without Authority: Work with senior ICs and leaders to keep momentum high, unblock progress, and align priorities.
• Be a Force Multiplier: Identify friction, fill gaps, and ensure the CTO is operating at their highest leverage.

What You’ll Need

• 4–8+ years in product, engineering, strategy, operations, or consulting (startups or high-growth tech preferred).
• A strong technical understanding - enough to engage productively with engineers, researchers, and product leaders.
• Proven experience managing complex projects with multiple stakeholders.
• Clear, structured communication skills - both verbal and written.
• Bias toward action. You get things done, even when the path is murky.
• High trust, low ego. You know when to lead and when to listen.
• Exceptional prioritization and time management. You’re comfortable juggling a lot.

Bonus Points

• Experience in a Chief of Staff, TA, product strategy, or hybrid product/ops role.
• Previous work with CTOs, technical founders, or exec teams.
• Background in AI, dev tools, or deep tech.

What Success Looks Like

• 30 days: You’ve built trust with the CTO, identified priority workstreams, and started owning small initiatives.
• 90 days: You’re running multiple high-velocity projects and helping keep the org aligned across product + tech.
• 6–12 months: You’re a trusted right-hand to the CTO and a visible operator across the technical leadership team.

Location

This role is based in our London office, with 4+ days/week in person expected. You’ll work closely with our technical and executive teams in a fast-paced, high-context environment.

Why You’ll Love It Here

At Synthesia, you’ll move fast, learn fast, and help build a category-defining company. We value ownership, clarity, and momentum - and you’ll be empowered to drive all three. You’ll be surrounded by thoughtful, ambitious teammates working at the cutting edge of AI and video.
