Set testing standards using Sitecore-focused tools

Bring in current Sitecore and web development practices

Mentor and train junior developers

Mandatory requirements (all must be met)

Hands-on C# and/or .NET development as your sole responsibility in the last 3 years (not a predominantly managerial or architectural role)

At least 5 years of hands-on Sitecore development, backed by a portfolio of web platforms

At least 2 years of hands-on experience with Sitecore 10 XP, including containers, analytics and marketing forms

At least 2 Sitecore migration or version-upgrade projects
