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. You'll 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. At Synthesia, Engineers are builders of the experimentation system, not just users of it – constructing A/B infrastructure, instrumentation, and metrics pipelines that power how the whole product grows.
Partner closely with product managers and data analysts to prioritize the highest-leverage work, make clear trade‑offs between experimentation velocity and long-term scalability, and translate ambiguous business problems into clean technical solutions. You'll 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 optimizing 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 line to revenue.
What We're Looking For
Experience in activation, conversion, monetization, 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
Benefits
The salary starts at EUR/GBP/CHF 100,000 base + stock option plan.
This is full‑time employment only – no contractors.
Everyone at Synthesia gets 25 days of leave + local holidays (no extra paid or unpaid leave possible).
Visa sponsorship available only for UK/EU residents who need support.
Potential remote work in UK, Germany, Switzerland, Ireland, or other EU locations subject to compliance.
