Ideal Candidate
The ideal candidate understands SFCC beyond basic storefront customization. They should be comfortable designing and troubleshooting complex backend flows involving SFRA, platform APIs, services, jobs, payments, orders, integrations, caching, and platform configuration.
At the same time, they should approach problems as a senior backend engineer—understanding when functionality belongs inside SFCC, when it should be handled by an external service, and how the commerce platform fits into the broader enterprise architecture.
