Are you interested in Blockchain technologies? Are you good at clouds? If yes, then keep reading!  

Sigma Software is looking for an experienced Performance Engineer. Grab the chance to become a part of the team building a blockchain platform that will be used by millions of Europeans in the future.

Feeling thrilled? You are welcome to join! 


Our Client is striving to become a part of European Blockchain Services Infrastructure with their product Relational Blockchain Nebula (RBN). RBN has the potential to address two important use cases: Digital Product Passports and Intellectual Property Rights.


Currently, the project team is working on finalizing the use cases and testing the blockchain to prove that RBN can meet technical requirements, such as high scalability and velocity, robustness, interoperability, and more.

Requirements for a blockchain network are very different compared to a traditional server cluster. In the blockchain world, each node in the network will be unique, so standard Kubernetes setup (with multiple identical servers) is not feasible. Therefore, traditional tools might not work. In the project, the team has several custom-made network management tools that are specifically created for their network needs.
