Senior Python / Conversational AI Engineer

Core Responsibilities

• Build and modify conversational flows across dialog, orchestration and knowledge layers.
• Design and optimize stateful, multi-step workflows, including session and context management.
• Perform RAG and knowledge-retrieval tuning to improve response quality and relevance.
• Design and maintain escalation logic, including transfer conditions, routing destinations, context payloads and reason-code registration.
• Work with LLM-driven conversational systems, including prompt behavior, guardrails and model-generated content.
• Integrate backend systems through established handler/API layers.
• Develop secure REST API integrations using appropriate authentication and certificate-management mechanisms.
• Author and maintain automated unit tests, mocks and platform-level conversational test cases.
• Maintain comprehensive regression test suites.
• Build and own CI/CD pipelines covering validation, automated testing and gated promotion across environments.
• Follow Git-based branching, release and environment-promotion strategies.
• Own application deployment and rollback procedures.
• Act as a first responder for production incidents.
• Diagnose production issues independently using logs, traces and metrics.
• Identify root cause and implement permanent fixes with corresponding regression tests.
• Manage configuration and feature-flag governance.
• Maintain design, state, test and implementation documentation aligned with actual system behavior.
• Analyze and reconcile platform changes originating outside version control and determine whether the impact is behavioral or cosmetic.
• Collaborate with engineering, product, QA, security and infrastructure teams.
