Our team is passionate about up-to-date technologies and is striving to build a world-class product. We’re looking for a motivated developer who will own the architecture and development of an end-to-end solution to one of our technical projects.

Examples of projects you could work on:

  • Engineering KPIs – Fully automate all eng KPIs collection, calculation and visualization
  • Wysiwyg editor for the marketing – We do not have a cms yet, but in summer we plan to have one. However it would be more convenient to edit the content on HP using wysiwyg editor, eg:, An intern could get hands on implementing the yet experimental tools (not v1 yet) to our infrastructure
  • Slido analytics – to be specified
  • Ultimate presentation experience – Help us build the ultimate presentation experience. You will learn about .NET, C++, Microsoft Office internals and some low level code
  • Meeting fun indicator – Indicate how many participants are currently interacting with Slido and how much fun they are having by making use of our new live data streams and displaying them as gauges
  • Same emojis on all devices – Last year we added support for emojis in polls, but in the current implementation we use emojis provided by the operating system. Help us make participant experience more consistent by having the same emojis across all devices
  • New poll results visualization – Play around with various data visualizations of our polls. Some types of data representation are more suitable for different data analysis than others. Currently we can show the data in a form of bars, but there are other options. What about showing inputs from participants in a form of pie chart or histogram?
  • Better wordcloud – Wordcloud is one of our most used poll types and we have a lot of wordcloud related feedback from customers to process. For example make the visuals of wordcloud consistent across all apps, improve styles, add animations, colors, etc. Be part of the process of figuring out what we should implement and do it!
