About the Role

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:

  2. Architecture as Design: this pillar includes the solution and technical design for transformation programs and business critical projects which need architectural guidance and support.
  3. Governance: this pillar is responsible for defining technical standards, and developing innovative tools that automate controls to ensure compliance.
  4. Colleague Enablement: this pillar is focused on colleague development, recognition, training, and enterprise outreach.

  • Design systems for scalability, resilience, and observability, including monitoring, logging, and alerting strategies
  • Contribute to cloud-native adoption, including containerization, infrastructure-as-code, and auto-scaling architectures
  • Influence technical direction and challenge the status quo by proposing innovative, pragmatic solutions
  • Take ownership and accountability for delivering high-impact outcomes aligned with team and organizational goals

  • Solid understanding of distributed systems, concurrency, scalability, and performance optimization
  • Hands-on experience with relational databases (PostgreSQL, MySQL, Oracle) and/or NoSQL databases (Cassandra, DynamoDB, MongoDB)
  • Experience with containerization and orchestration (Docker, Kubernetes)
  • Familiarity with infrastructure-as-code tools (Terraform, CloudFormation, etc.)
  • Experience with messaging and streaming platforms such as Kafka, RabbitMQ, or JMS
  • Practical experience with cloud platforms (AWS, Azure, or GCP) and cloud-native development patterns
  • Hands-on experience in test data generation and unit test development and execution
  • Preferred: Basic understanding of AI/ML concepts and Generative AI technologies, including LLMs, prompt engineering, and Retrieval-Augmented Generation (RAG)
  • Experience with API design standards, OpenAPI/Swagger, versioning, and contract-driven development
