• Develop Lambda-based fulfillment workflows integrated with REST APIs, event buses (EventBridge), and Step Functions

• Collaborate with conversation designers and UX teams to craft natural and context-aware dialogues

• Implement DevOps pipelines using AWS CodePipeline, GitHub Actions, or similar CI/CD tools

• Establish and maintain observability and monitoring for bot health, latency, and NLP performance

• Drive best practices around testing, deployment, and bot lifecycle management

• Ensure scalability, security, and compliance (e.g., SSO integration, audit logging, data masking)

Minimum Qualifications

• 5+ years of software development experience with at least 2+ years focused on Conversational AI

• Proven delivery of production-grade bots on Amazon Lex v2

• Strong AWS serverless background: Lambda, API Gateway, DynamoDB, Step Functions, EventBridge

• Demonstrated experience migrating from Microsoft Bot Framework or Azure Bot Services

• Proficient in Python or Node.js for Lambda development

• Experience designing enterprise-grade conversational flows

• Familiarity with Infrastructure-as-Code (CDK, Terraform, or CloudFormation)

• Strong understanding of NLP concepts, error handling, fallback design, and session state logic

• Experience working in agile delivery environments with design, QA, and platform engineers

Preferred Qualifications

• Experience with AWS AI/ML services like Comprehend, Transcribe, or Polly

• Understanding of data governance and compliance standards (GDPR, HIPAA)

• Background in deploying bots into regulated industries (finance, insurance, healthcare)

• Exposure to chatbot analytics tools and NLU performance tuning

• Familiarity with conversational analytics platforms (e.g., Amazon Lex analytics, Dashbot, Voiceflow)
