   • Incorporate security by design — covering threat modelling, secret management, KMS/HSM usage, PII handling, and auditability across all solution designs.
   • Produce and maintain mandatory Design Documents per requirement, including system context diagrams, sequence diagrams, ERDs with tenancy annotations, OpenAPI/GraphQL specs, and non-functional requirements.
   • Provide hands-on delivery enablement through design and PR reviews, ensuring implementation fidelity to architecture across build, test, and rollout phases.
   • Define performance budgets, capacity models, and test strategies including contract tests, chaos/resiliency tests, and load tests; ensure golden paths and runbooks are in place for operations.
   • Mentor engineering teams on SDK architecture, integration patterns, and multitenant best practices; curate reusable reference architectures, frameworks, and documentation templates.
