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.
About the role:
- Own and ship high-impact experiments and features end-to-end – from hypothesis to production – that directly move activation, conversion, and revenue metrics.
- Design for measurable outcomes, not just output, and iterate quickly based on data.
- Work full-stack across the Growth surface: activation flows and onboarding, self-serve and freemium infrastructure, pricing and packaging mechanics, PQL-to-enterprise funnels, viral and sharing loops.
- Build and extend the team's experimentation platform.
- Partner closely with product managers and data analysts to prioritise the highest-leverage work, make clear trade-offs between experimentation velocity and long-term scalability, and translate ambiguous business problems into clean technical solutions.
- Operate with a high degree of autonomy and be expected to define what gets built, not just how.
Team you would be joining – Growth:
- The Growth team is dedicated to driving high NDR and sustainable revenue growth through self‑service and freemium offerings, improving user experience, and optimising conversion pathways while aligning with enterprise goals.
- This team operates at the intersection of product, engineering, and data, shipping experiments rapidly and iterating based on measurable outcomes.
- You'll work on core surfaces that directly impact user journeys and business performance, in a PLG environment where engineering decisions have a direct and visible link to revenue.
What we’re looking for:
- Experience in activation, conversion, monetisation, or PLG systems – not growth marketing or CMS/content engineering.
- Experience building or significantly extending experimentation infrastructure – A/B systems across cached and non‑cached pages, metrics pipelines, experiment orchestration – at the builder bar, not just the user bar.
- A habit of quantifying your own impact: you default to metrics (conversion %, activation rate, ARR lift, INP/TTI) when describing what you shipped.
- Strong product sense and ownership mindset – comfortable owning the problem definition, trade‑offs, and technical approach, not just the implementation tickets.
- Experience with viral mechanics, sharing loops, or team‑expansion features is a strong plus.
