Senior Software Engineer - Fullstack

Rasa TechnologiesRemote - United Kingdom OR Germany17 days ago


We're looking for a driven Senior Fullstack Engineer with professional experience building large-scale web applications. This is an opportunity to own interesting technical and product challenges. You will be working with other Rasas to craft products from the ground up and solve complex problems that support our mission.

As a Remote first company, we believe that the internet is where the work happens, an office is just somewhere you can connect to the internet. We believe that everyone can make a difference at Rasa no matter where they are based. If you would like to work in an office then we have R&D offices in Berlin, Germany, and in Edinburgh, UK. But our focus is to continue to build our team remotely across the UK and Germany.


Software Development at Rasa is not only about writing code. You'll have to come up with good architectural designs, quality code, and break an ambitious long-term vision down into milestones and issues.

We don’t draw a hard line between our engineering and research teams, we all work on the same stack and share work, knowledge, and tools. A lot of the code we create is open source and used by a large community of developers. The driver for our development efforts is this: what would help developers build great conversational software? What can we enable them to build that they couldn't do currently?

We do fundamental machine learning research, and we ship commercial quality software that puts it to use. We mostly work in Python and TypeScript, but dip into other languages when it makes sense to. Because engineering is so close to research, you’ll quickly learn a lot about machine learning, model management, data analysis workflows, and what it takes to ship machine learning applications into production.

We are looking for a Fullstack Engineer who combines technical, communication, and analytical capabilities and who will have the opportunity to design and develop creative, compelling, and cutting-edge systems.
