Sr Software Engineer I - Enterprise Architecture

About Enterprise Architecture:
Enterprise Architecture is an organization within the Chief Technology Office at American Express and it is a key enabler of the company’s technology strategy. The four pillars of Enterprise Architecture include:
Architecture as Code: this pillar owns and operates foundational technologies that are leveraged by engineering teams across the enterprise.
Architecture as Design: this pillar includes the solution and technical design for transformation programs and business critical projects which need architectural guidance and support.
Governance: this pillar is responsible for defining technical standards, and developing innovative tools that automate controls to ensure compliance.
Colleague Enablement: this pillar is focused on colleague development, recognition, training, and enterprise outreach.
