You will spend the majority of your time in code and in the AWS console: building contact flows and AI agents, writing Lambda functions and CDK stacks, developing React-based agent and admin tooling, and debugging production issues on systems that serve tens of thousands of agents and millions of customer interactions. You work within architectures set by practice leads, and you’re expected to pressure-test them, propose better patterns, and own the implementation quality of your workstream from first commit through production cutover. This role blends deep Amazon Connect platform engineering, generative AI development on Bedrock and Claude, and full-stack serverless work, with regular direct interaction with customer engineering teams.</p> <p> </p> <p><strong>Your Assignment</strong></p> <p><em>AI Agent & Conversational AI Development</em></p> <ul> <li>Learning and building with AI both for productivity and for enhancing client solutions.</li> <li>Experience with: UX/UI, LLMs, AgentCore, GenAI, automated testing, CI/CD, IaC</li> <li>Implement barge-in handling, fallback, and error-recovery behavior for voice AI, and validate it with turn-by-turn trace analysis</li> <li>Optimize inference cost and latency hands-on: model tier selection (Haiku vs. Sonnet vs. Opus), prompt caching, and token budgeting against containment- rate targets</li> <li>Diagnose AI agent performance using observability tooling (agent spans, and CloudWatch) that correlates contact flow logs, conversation transcripts, AI agent spans, tool executions, and token usage to isolate latency, cost, and quality issues</li> <li>Build conversational experiences where intent-based NLU is the right fit, including multilingual support and SSML-tuned voice interactions</li> </ul> <p><em>Full-Stack & Portal Engineering</em></p> <ul> <li>Build custom Agent Workspace experiences with third-party app embedding, and CRM screen-pop integrations (Salesforce, ServiceNow, Oracle, custom systems)</li> <li>Build serverless, event-driven backends with Lambda, EventBridge, Step Functions, SQS/SNS, DynamoDB, and Kinesis for real-time event processing and customer journey orchestration</li> <li>Treat accessibility as a first-class requirement: WCAG 2.1 AA compliant components, automated axe-core/Playwright accessibility scanning, and support for VPAT/Section 508 documentation on government and enterprise engagements</li> </ul> <p><em>Infrastructure
