As a Fullstack Engineer in our team Kino, you will build creative tools for our customers who depend on our image and video templates, asset library and creative performance insights in automating and scaling their advertising.

Kino is at the core of our product offering

Our templating tools are a flagship feature of the Smartly.io app, including a video editor written in TypeScript/React/Redux and a Node.js rendering backend. During peak hours, our image template rendering backend renders up to 18 Gb of images per second on over 600 servers.

In the near future, we are looking to kickstart developing creative insights as a part of the tool, focusing on analysing how our customers' creatives are performing as well as giving them actionable insights.

We work with technologies like TypeScript, Node.js, Ruby on Rails, PostgreSQL, Redis, React, Redux and Styled Components.
