Senior Developer – Sitecore XM Cloud (Replatform Initiative)
Our client is undertaking a major replatforming initiative from Sitecore XP to Sitecore XM Cloud and is seeking a Senior Developer to play a key technical role in designing, building, and optimizing a modern, headless digital experience platform.

· Address security scan findings and ensure compliance with security and quality standards.
