What will you be doing?

Working remotely is also possible!

Within this position you fall under a partner organization of Coosto. This partner organization is a data supplier that is active worldwide in collecting millions of public vacancy data. Within this position you will work in a team that focuses on an efficient way of collecting this data through web crawling / spidering.

As a result, you come into contact with all layers of our architecture, consisting of various distributed applications, databases, queues and file systems. We work with Python, Bash / Shell, GlusterFS, MySQL, Redis, Kafka and RabbitMQ and we run all of this in Docker and / or Kubernetes.

As a Senior Backend Developer you will work in a Scrum team and you will realize the product roadmap together with the team. You will of course make an essential contribution to this product roadmap. You will work on further defining and expanding our software landscape and the associated architecture, based on a microservices architecture.
