About the role
  • You will focus on friction points around primarily backend issues for all teams in Engineering (90 Engineers). How should we do inter-service testing? Some teams are using monorepo, others aren't. How can we bring overall stability up? Generally steering BE in the right direction. In the near future, standardising things across all of Engineering and bringing R&D teams (another 40 Engineers and Researchers) closer.
  • You will have ownership of projects that span quarters, requiring you to have the ability to break a problem down into small steps that can be delivered and validated iteratively.
  • You will evaluate your own work, leveraging our data pipeline and frameworks that we have established to understand the impact your features have on our commercial objectives and pivoting where necessary.
  • You will consider the long-term direction of Engineering, making sure that we are developing the engineering capabilities that will allow us to stay ahead of the challenges we are likely to encounter in 12-18 months' time.
  • You will work end-to-end, from our client application written in React to our monolithic backend written in Python, and lead projects that span across multiple teams.
What we're looking for:
  • At least ten (10) years of experience as a software engineer, at least 2 at the Senior Staff/Principal level (L7+).
  • Previous leadership experience in driving projects across multiple teams (50+ Engineers).
  • Experience in a high-performing engineering Org that is operating at scale. This could come from a scale-up environment or a more established organization recognised for building and shipping with a great engineering culture.
  • An ability to work across the stack, with deep knowledge on server side and all things back end related.
  • Relevant engineering experience for a team building an enterprise-grade SaaS product. Extra points for delivering AI-powered video generation product, billing systems, experimentation platforms, video delivery systems, online editors, real-time collaboration and so on.
  • Strong alignment with commercial success.

  • This is a remote role from an EU country, UK or Switzerland.
  • The salary starts at EUR/GBP/CHF 200.000 base + stock option plan.
  • This is full-time employment only - no contractors possible - usually through OysterHR.
  • Everyone at Synthesia gets 25 days of leave + local holidays (no extra paid or unpaid leave possible).
