• Design the reusable workflow foundation for role permissions, stage gates, approval routing, scenario/version management, change ledger, validation, reporting, exports, and reconciliation.
• Define data-isolation and access-control patterns so multiple Business Transformation products can reuse shared technical components while maintaining separate security rules, data models, workflows, user groups, and operating processes.
• Establish nonfunctional requirements for scale, availability, recoverability, observability, performance, maintainability, disaster recovery, and support.
• Lead technical design reviews, architectural decisions, risk management, engineering standards, and solution documentation.

• Strong knowledge of domain-driven design, API architecture, relational and event-driven data models, identity and access management, and enterprise integration.
• Experience designing systems that handle sensitive employee, financial, legal, or regulated data.
• Deep understanding of role-based access control and preferably attribute-based or field-level authorization.
• Technical fluency across modern full-stack technologies such as React/TypeScript and enterprise backend services using Python/FastAPI, Java/Spring, Node.js, .NET, or comparable stacks, with ability to go hands-on when needed.

• Familiarity with AI-assisted workflow patterns, with a strong understanding of where deterministic rules and human approval must remain authoritative.
• Background building solutions for regulated global environments with strict audit and governance requirements.
