Job Description:

You will be exposed to a wide spectrum of technologies such as Kubernetes clusters, connectivity, databases, kafka clusters, as well as numerous opportunities to create automations to eliminate toil and improve developer experience.

We're looking for people who have a curious mindset, thrive in collaborative squads, and are passionate about new technology. By their nature, our people are also solution-oriented, commercially savvy and have a head for fintech. We work in tribes and squads that focus on specific products and projects – and depending on your strengths and interests, you'll have the opportunity to move among squads within the tribe.
