About The Position

The Principal Architect – Applications Engineering is responsible for the end-to-end technical architecture, design, and integration strategy for enterprise applications across the BEUSA family of companies. This includes line of business applications integration with ERP and enterprise platforms, and the technical delivery of application features that support business operations, field service, manufacturing, and customer-facing workflows, including an in-house industrial operations platform. This role serves as the technical authority for application architecture, defining standards, patterns, and integration designs that ensure scalability, security, maintainability, and alignment with the broader data and AI platform strategy. The Principal Architect – Applications Engineering will collaborate closely with the Principal Architect – Data Platforms to establish clear data contracts and integration patterns, and will partner with Product Management, the AI/ML Engineering Manager, and business stakeholders to translate requirements into robust, production-ready technical solutions. The Principal Architect – Applications Engineering will lead the design and implementation of multi-tenant SaaS products (where applicable), API and integration orchestration, DevOps and CI/CD practices, and operational excellence for production application environments. This role is hands-on enough to produce reference implementations and conduct technical reviews, but is primarily focused on system-level architecture, cross-system integration, and raising the technical bar across application development teams. The ideal candidate is an experienced applications architect with deep expertise in cloud native application design (particularly on Microsoft Azure), enterprise system integration, industrial operations platform development, modern development practices, and a track record of delivering scalable, resilient applications in complex operational environments.
