Who are we

On a mission to make video easy for anyone …

Synthesia is the world’s #1 AI video generation platform. Well, it’s actually a video production studio β€” in a browser. As in, no cameras or film crews at all. You simply choose an avatar, enter your script in one of 60 languages, and your video is ready in minutes. In Synthesia, you can build personalised on-the-fly videos, give your chatbot a human face or run 24/7 weather channels in different languages, to name just a few of the possibilities. 🎬

We believe the future of media is synthetic, and we are on a mission to turn cameras into code and make everyone a creator. Not sure what we’re talking about? Check out our brand video that explains what we’re doing at Synthesia in a way that even our grandparents *kind of* understand what this AI video stuff is all about.

About the position

In this position, you'll join our extremely talented Platform team. You'll have a chance to work on scaling our current, fast-growing product and shape some of the next products in our pipeline.

You would be working on features like billing, user provisioning, workspaces/collaboration, asset management, the way we deliver videos and in the future, we will also need to build a custom internal tool for our moderation team.


  • You ideally have a minimum of 5+ years of experience working in software development (in any high level language)
  • You have experience working on SaaS applications
  • You have the experience that ranges from early-stage start-ups to bigger, well-established organizations
  • You can work cross-stack
  • You like to take ownership of features and execute from planning to production
  • You are very pragmatic in your approach and you don't over-engineer
  • You have strong CS fundamentals
  • Experience with developing enterprise features as described above is a huge plus
  • A good level of spoken and written English is required

How we work

We have a fast yet non-hacky development style. We work strictly with product managers who have a technical background. As a result, we do not overwhelm engineers with unrealistic expectations/requirements, and we can therefore move forward much faster. Well, we don’t have unrealistic expectations/requirements in the first place, since we see our roadmap as a set of high-level goals and we have no fixed timelines on deploying features - we want to get things to production as fast as possible. We do that by pushing features behind a feature flag - so not all users see all features, but our production is always updated. This brings zero-downtime deployments, backward compatible features, and similar challenges since our users should never be impacted. Our engineers have one sync meeting per week, async text Slack dailies, we have no dedicated QA people, we work in super small & independent teams, we have no Jira and in our team, we only have engineers, no code monkeys.

For us, it's simple: give people time to do deep work. And help specify features that are limited in scope while discouraging hacky workarounds.

It's early for us and we don't know how right we are yet. But after two years of building our product team and core engineering principles, we can see that we are on the right track. Progress over perfection.

Our stack & some context

We started to work on our main product - Synthesia STUDIO - almost two years ago with a very small team of engineers (BE and FS). We now have a functional product, that we develop, push forward and improve constantly. While we know, we have a long way to go, to bring our product to where we want it to be, we also have to be mindful of our existing userbase, which is also really involved with us and provides great feedback for each update and new feature we roll out. We have a lot of custom components and multiple layers of complexity, our product is constantly changing but if we try to sum up our stack:

  • Frontend is TypeScript/HTML/CSS using React.js + Redux
  • Backend is a mix of Python, Flask, Node.js (for real-time cooperation), and C++ components (we have our own Chromium fork for headless video rendering) that are mostly containerized with Docker, and hosted on a number of AWS services (Lambda, Fargate, EC2, EKS)
  • We have a dedicated DevOps Engineer
