Scala Engineer - Remote (North/South America)

Constellation Network is looking for full time Scala engineers to join our remote protocol team (North/South Americas). Protocol developers contribute to the core software services that power our live decentralized blockchain network of 300+ nodes. They also contribute to Constellation’s Metagraph Framework which is a development framework that allows community developers to create their own layer 1 subnets on the network, called Metagraphs, in addition to working on other important network infrastructure.

About Constellation Network:
Constellation is a decentralized network, written in Scala, with a focus on allowing developers to build highly scalable application-specific blockchains. Developers can build metagraphs, or subnetworks, with the ability to customize their applications based on their own business logic for data validation, consensus, and include token-based incentives or fees. The unique microservice-inspired architecture of metagraphs allows them to scale to meet the needs of big data and high throughput workloads. In addition to our open source public network, Constellation has worked with the US Department of Defense since 2019 to develop military-grade cross-chain messaging capabilities for the US Air Force and other federal agencies.

Our team is 100% remote and international, with most of our work being open-source.
