Senior Full Stack Software Engineer (various levels) - Production Team @ Celtra d.o.o.

Opis delovnega mesta

1. What is our team responsible for?
- The Production team is responsible for our industry-leading web-based WYSIWYG editor, loved by thousands of designers who use it daily to build image, video, and social ads.
- Unlike tools like Photoshop which require you to build one asset at a time, global advertisers like Adidas, Spotify, and Unilever use Celtra to automatically generate tens of thousands of ad variations for different languages, countries, products and platforms.

2. Who are we searching for?
We are looking for Fullstack and Frontend software engineers with appreciation for Frontend technologies to join the journey of building Creative Automation team (CA). We are looking for a motivated, constantly-learning engineer who understands how browsers and their APIs work.

3. In the past we built
- We have built an industry-leading web-based WYSIWYG editor that allows designers to produce Creative templates with a great variety of design elements, smooth animations, video editing timelines and smart image functionalities.
- Together with our specialised spreadsheet-like content editor, marketers and designers are able to scale these templates into thousands of ads variations, faster and easier than ever before.
- Our Photoshop plugin brings existing design tools closer to Celtra.
- For our content scaling to work, we implemented video transcoding and transforming services for cross-platform and cross-product support.
- Along the way, we also created our own DesignSystem UI components library, for developers to use.

4. What are the challenges ahead?
- We believe that software should be easy to use and enable users to collaborate efficiently. We want to bring multiplayer functionality in our Authoring tools, allowing editors collaborating on design and content simultaneous. For that, we'll need to rework our current architecture, along with introducing a novel concept of an integrated WYSIWYG editor with multiple content spreadsheets.
- To bridge the gap between existing design tools and our content scaling solution, we will invest our effort in Figma & Photoshop integrations, while also providing our users with time-saving features like AI-based automatic focus and cropping service. Additionally, we are also planning to release the next generation of our headless Chromium-based rendering pipeline.

5. What kind of tech stack do we use?
Our CA product is using NodeJs, PHP, MySQL, Redis and Python. For both products, on the front-end, we use Vue.js, NPM, Webpack and vanilla JavaScript when needed. Everything runs on the AWS cloud, and the Kubernetes cluster orchestrates it.
