Key Responsibilities
• Lead the architecture and development of the EBC backend/runtime platform, including APIs, session management, identity context, and integrations.
• Design and develop scalable backend services using advanced Python, asynchronous processing, REST APIs, and streaming APIs.
• Implement robust workflow and session-state management, including retries, timeouts, caching, schema validation, and structured error handling.
• Establish API-first architecture using Apigee, versioned contracts, authentication, authorization, rate limiting, and user-context propagation.
• Integrate backend services with UI applications, AI gateways, agents, BigQuery, Stardog, and other enterprise platforms.
• Design efficient data-access patterns using advanced SQL and BigQuery, including curated/authorized views, query optimization, filtering, pagination, transformation, masking, and role-aware data delivery.
• Integrate conversational AI and agent capabilities while supporting structured AI responses, citations, and graceful handling of unavailable downstream services.
• Integrate backend applications with semantic and knowledge-graph interfaces.
• Design and support cloud infrastructure using GCP, GKE, Docker, Kubernetes, and Terraform.
• Implement service accounts, secrets management, workload identity, networking, DNS, load balancing, and private connectivity.
• Establish automated CI/CD pipelines covering build, testing, deployment, promotion, rollback, credential rotation, and environment management.
• Drive unit, integration, contract, regression, performance, load, and resilience testing.
• Implement production observability through logging, metrics, distributed tracing, dashboards, alerting, and SLIs.
• Lead incident response, root-cause analysis, recovery procedures, and production support practices.
• Ensure secure coding, least-privilege access, identity propagation, secrets management, masking, audit logging, and protection of sensitive information.
• Conduct architecture, design, and code reviews while mentoring engineers and establishing reusable engineering standards.
