Our culture

Our engineers enjoy a lot of autonomy and flexibility to do what they do best: solve problems. 

Concretely, this means that each of us takes ownership of their tasks and projects and are free to organise their time as they see fit. This also means that there is no micromanagement and that we keep meetings to a minimum to allow for focus time to code. 

We are 100% remote and have an international team, but we strive to meet regularly in offsites. The last one was in Portugal in the beginning of the month where the team got to know each other better and worked on an exciting new project that they delivered after that week. 

We love code reviews, debates and knowledge sharing. These happen freely within teams as well as cross-department through guilds and other initiatives.  

Here is our tech stack.

• Backend: Python 3.8, Django
• Frontend: ES2018, React, Redux, styled-components, Jest
• Database: PostgreSQL, Redshift, DynamoDB
• Continuous Deployment/Tools: Gitlab/GitlabCI, PyCharm, Goland
• Infrastructure: ECS, Kubernetes (EKS), Istio, Prometheus stack, AWS, Chef

How we behave.

We're human. Our diversity and unique experience make us strong. We allow ourselves to be vulnerable and treat one another with grace. We take ownership. We expect one another to take initiative and trust each person to make decisions based on the best available data. We have passion, perseverance and urgency to hit our goals and work together to create the best outcomes. We think big. We innovate and challenge the status quo to maximize the value we deliver to our users. We constantly experiment with new ways to drive excellence. We're real. We are honest with ourselves and one another. We listen, speak up, and are ready to change our minds.
