  • Define data contracts, schema evolution strategies, and idempotent/eventual consistency patterns
  • Embed AppSec best practices, OWASP controls, secure API/auth (OAuth2/OIDC), and zero trust patterns
  • Ensure compliance with regulatory and audit requirements where applicable
  • Translate business needs into technical roadmaps and architecture runway
  • Communicate trade-offs and decisions to both technical and non-technical audiences

Requirements

  • 15–18 years of progressive experience building enterprise systems
