We are seeking a Solution Architect to design and lead a central email gateway. It will sit between the client's commerce platform, its middleware (enterprise service bus) and a recent email service provider, and will carry all business-critical transactional email, such as order, shipping, refund and account notifications. The gateway offers two integration models:
a pass-through API for systems that are ready to use the current provider directly
a backward-compatible API that mimics the legacy provider, so existing systems only need to change an endpoint
The Architect will own the AWS target architecture, the versioned API contracts, a configuration-driven mapping model, and the resilience design needed to make sure no email is lost or sent twice. The role leads a small cross-functional team on a short build window, drives technical decisions with the client's architects, and owns cutover readiness and early-life support.
