Senior Software Engineer

You will be working on developing, maintaining, and scaling the data & software powering our Delta platform. The Delta mobile application is written in React Native and the desktop app is written in React, using Next.js. Our tech stack mostly consists of Typescript (on node.js). We also have some specialized microservices in Golang and Rust, but having experience with JS is a must. Data is persisted in MySQL and DynamoDB, we also leverage Redis and ElasticSearch for performance reasons, where needed. Using Github Actions as CI/CD, our code gets tested, linted and scanned for security issues before it gets deployed to production (which can happen multiple times per day). All this lives in the AWS cloud, leveraging infrastructure as code. In short, you'll be responsible for our backend platform powering the Delta apps, serving massive amounts of users. The full requirements are listed in full below.

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 communicating in English. Not looking for remote positions though.

You'll be part of a scale-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!

What else? Delta is aiming to be one of the household names in fintech, so you'll be growing an app that is already used today by millions 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. Recently we’ve launched a full-fledged investment tracker that allows investors to keep tabs on their stocks, indices and even funds. Our main goal is to become one of the best and most-used platforms and a household name 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.
