You'll be working in our office in Ghent, Belgium. We're located right in the city center in a gorgeous historic building, which is pretty cool. Psst... no worries if you can't speak Dutch, we're used to communicate in English. Please note we are not looking for remote hires though.

Right, the job! Well, first of all, you'll be part of a start-up which is part of a big company (eToro). Which means you'll be working within the Delta start-up mentality, surrounded by lots of experience and the empowering structure of a bigger entity. Win-win!

We're looking for engineers who want to be a part of developing, maintaining, and scaling the data & software powering our Delta platform, which is mainly built using NodeJS. Amongst others, you'll be responsible for our data ingestion & processing pipeline and our backend platform powering the Delta apps, serving massive amounts of users.

What else? Delta is one of the household names in crypto, so you'll be working on an app that used by tens of thousands of dedicated investors, every day. We get lots of feedback and even more love from our users, which is really motivating and makes everybody here even more driven to keep adding value. Our goal is to become one of the best and most-used platforms in the fintech space. If you're up for that challenge, you'll fit right in.

We don't want to sound like a broken record but right now, we're really not looking for remote positions. Even the most awesomest of awesome applicants will unfortunately be rejected for the time being.
