- Design asynchronous processing, queues, background workers, caching, and other supporting backend services where required.
- Build application services supporting AI chatbots, AI agents, document processing, customer portals, and SaaS products.
- Ensure backend services are reliable, maintainable, observable, and production-ready.

AI Application Architecture

- Work closely with the Applied AI Engineer to integrate AI capabilities into production software.
- Define service boundaries between the core application backend and AI services.
- Design architectures for RAG, model gateways, AI agents, document processing, and AI-powered workflows.
- Support integration with OpenAI, Google Gemini, OCI Generative AI, open-source models, and other providers.
- Ensure AI services are securely integrated with business systems and customer data.

Security & Reliability

- Establish secure software architecture and development practices.
- Work with the DevOps Engineer to implement appropriate authentication, authorization, encryption, secrets management, logging, auditability, and tenant isolation.
- Participate in threat modeling and security reviews for customer solutions.
- Ensure systems are designed with appropriate availability, backup, disaster recovery, and failure-handling mechanisms.

Testing & Quality

- Establish engineering testing standards.
- Ensure developers write appropriate unit, integration,



and API tests for the components they own.
- Review test coverage for critical backend functionality.
- Work with the DevOps/QA owner on end-to-end and release testing.
- Participate in production incident analysis and root-cause investigations.

- new products follow consistent architectural patterns;
- backend systems are reusable across multiple clients;
- customer data is properly isolated;
- deployments are repeatable;
- engineers can work independently;
- AI capabilities integrate cleanly with application systems;
- technical debt is controlled rather than accumulating rapidly.
