• Standardize API gateway and north-south access patterns to ensure secure and consistent service exposure.

• Produce and maintain reference architectures, design documentation, and architectural guardrails.

• Review and validate platform design proposals to ensure alignment with long-term strategy.

• Stay hands-on through proof of concepts and technical deep dives to validate architectural decisions.

• Partner with engineering, security, and product stakeholders to ensure standards are practical and widely adopted.

Requirements
