Senior Software Engineer, Distribution

OVERVIEW You will work closely with a geographically diverse engineering organization and will be embedded within our Distribution domain team, owning the engineering surface for the 4U Engage platform — the product through which investment companies publish, wealth management firms distribute, and financial advisors consume compliant content. Beyond contributing code, this role is expected to actively shape architectural direction through hands-on guidance, clear technical judgment, and pragmatic systems thinking. Your initial focus will be learning the existing architecture, domain models, and full-stack delivery patterns across the platform's PHP API layer, Angular frontend, and surrounding .NET microservices. A core element of this work is the ongoing extraction of bounded domains from the PHP monolith into purpose-built C# / .NET microservices — a deliberate, platform-wide modernization already underway — and this role will be an active participant in advancing that transition within the Engage domain. Over time, you will take ownership of that architectural direction, influence cross-team decomposition patterns, and help guide the long-term evolution of the platform toward a fully service-oriented model. In this role, success is measured not only by features delivered, but by improved system clarity, stronger service boundaries, reduced architectural friction, and the team's ability to move faster and more safely over time. Lead by example through thoughtful design, high-quality code, clear documentation, and constructive technical discourse. RESPONSIBILITIES - Apply systems thinking to full-stack design across C# / .NET microservices, an Angular SPA (4u-ui), and a PHP 8 / Slim 4 monolithic API (4u-api) — accounting for feedback loops, blast-radius constraints, and second-order effects on downstream event consumers. - Contribute to team-owned C# / .NET microservices, particularly search-service (OpenSearch-backed full-text search) and notifications-service (em
