Our humble expectations

Building a brand new support chat tool is an exciting and challenging problem. We are looking for someone eager to create a scalable, highly available real-time messaging service for our 9M+ users. Challenges include real-time messaging, ensuring that messages are reliably stored and delivered, designing and building a conversations inbox with prioritization, attachment, and push notification systems. That’s just to start with.

The potential tech stack that we are considering is MongoDB for storing general metadata, distributed KKV databases like Cassandra for storing messaging archives, Node.js for iterating quickly and building a REST API, and Elixir for building a scalable real-time messaging system.

Experience with high traffic and high-performance projects and good knowledge of NoSQL databases like MongoDB, Cassandra, or similar would be highly valuable. Great if you consider yourself flexible enough to work both with Node.js and Elixir as well as other technologies depending on the problem we face.

It is also a bonus if you have experience working with real-time projects like chats, multiplayer games, signaling servers for voice/video communications, or breaking news providers so you can demonstrate how to build reliable clients and backends to serve our customers needs.

We value an attitude of constant improvements and also the ability to create new things from scratch. An entrepreneurial mindset of taking ownership of what you've built is a must. Join the team with a huge opportunity to make an impact. 

Next steps

The compensation will be a negotiable combination of monthly pay and Wolt stock options. The latter makes it exceptionally easy to be excited about our company growing and doing well, as you'll own a piece of the pie.
