Blockchain developers

Blockchain developers.

Developers will likely have the greatest career opportunities in the nascent blockchain field; financial services, governments and tech companies are all seeking to find ways blockchain can better serve their clients.

Technology skills needed as a developer include: Microsoft SQL Server, Visual Studio, .NET, MVC, AJAX, SQL, C, C++, C#, Javascript, Node.js, JQuery, SOAP, REST, FTP, HTML, XML, XSLT, XCOD, Neural-networks, Regression, Agile Scrum, MYSQL.

Blockchain engineer

This job envisions understanding a company's tech needs and create the blockchain apps that address those needs.

"You may work on implementing assets and accelerators; set up company infrastructure to use Ethereum and bitcoin, and may analyze code and organizer blockchain programming training for new employees" Steele wrote.

Blockchain engineers should have a high level of skill in: Java, Hyperledger Fabric, Ripple, Solidity, Python, bitcoin, Oracle Identity, as well as access management solutions.
