Sr. Full Stack Developer (Senior AI Agent Developer)

Sr. Full Stack Developer (Senior AI Agent Developer) Job Location - NY, NY JOB DESCRIPTION Position Overview We are seeking a seasoned, hands-on Senior AI Agent Developer on a contract basis to lead the design, development, testing, and deployment of enterprise-grade conversational AI agents and intelligent workflow automations. In this role, you will be instrumental in architecting Conversational AI solutions natively within Google Cloud Platform (specifically leveraging GECX / Dialogflow CX), orchestrating multi-cloud integrations across Azure and ServiceNow, establishing automated CI/CD deployment pipelines in Azure DevOps, and validating systems through automated test frameworks. The ideal candidate brings strong polyglot development capability across .NET, Python (must have), TypeScript, and JavaScript, deep multi-cloud experience, and a proven track record delivering within a Scaled Agile Framework (SAFe) environment. Key Responsibilities Agent Architecture & Implementation: Design, build, train, and test conversational flows, intents, custom route groups, and LLM-powered tools within Google Cloud Platform using GECX / Dialogflow CX. Full-Stack & Backend Integration: Develop robust RESTful APIs, webhooks, and microservices in .NET, Python, or Node.js to integrate conversational agents with ServiceNow and Azure enterprise systems. DevOps & Pipeline Automation: Build, maintain, and enhance automated CI/CD pipelines in Azure DevOps for environment provisioning, validation, and continuous deployment of agent configurations and fulfillment services. Automated Quality Engineering: Implement automated test suites covering unit logic, webhook APIs, dialog flow regressions, and end-to-end conversational journeys. Data Querying & Performance Tuning: Write and optimize complex SQL queries for conversational analytics, reporting, and backend data operations. Agile Execution: Actively participate in SAFe Agile ceremonies, including Program Increment (PI) planning, sprint execution, backlog refinement, and cross-team dependency mapping. Required Skills & Qualifications 1. Deep Conversational AI Expertise (GECX / Dialogflow CX): Proven track record of designing, building, and deploying enterprise-scale virtual agents using Google Cloud Platform conversational frameworks, specifically GECX / Dialogflow CX, including state handlers, route groups, webhook fulfillment, condition rules, and generative agent capabilities. 2. Core Polyglot Development (.NET, Python, TypeScript, JavaScript): Extensive hands-on experience building backend services, API fulfillment webhooks, and asynchronous workflows using .NET (C#) alongside Python, TypeScript, and JavaScript. 3. Automated Testing & Quality Engineering: Strong hands-on experience implementing automated testing strategies for conversational systems and APIs-including unit testing, mock services, integration testing, and regression test suites for dialog flows using modern test frameworks (e.g., NUnit/xUnit, PyTest, Jest, or Postman/Newman). 4. Automated CI/CD Implementation in Azure DevOps: Demonstrated mastery in designing and configuring production-ready CI/CD pipelines in Azure DevOps (YAML pipelines, release gates, automated linting, test execution, and deployment artifacts). 5. Enterprise Multi-Cloud Integration (Azure & ServiceNow): In-depth experience integrating distributed cloud services across multi-cloud environments, specifically connecting conversational agents with ServiceNow APIs (Incident, Change, Service Catalog, Flow Designer) and Azure services. 6. Advanced SQL & Enterprise Data Operations: Strong proficiency in writing complex SQL queries, relational database modeling, and data manipulation to support dynamic agent lookups, reporting, and transactional verification. 7. SAFe Agile Methodology Experience: Solid experience operating within a Scaled Agile Framework (SAFe) enterprise environment, actively engaging in Program Increment (PI) planning, sprint iterations, user story sizing, and coordinating cross-functional ART (Agile Release Train) dependencies. 8. Modern Development Workflow & Tooling (VS Code / Antigravity): Fluency with professional developer toolchains, Git-based version control, and proficiency coding, debugging, and running local emulations inside modern IDE environments like VS Code or Antigravity. 9. AI Agent Architecture & Fallback Orchestration: Demonstrated capability to architect fault-tolerant conversational agent interactions, context and session variable management, prompt engineering, intent classification, and seamless human escalation / fallback workflows. 10. Enterprise Security & Cloud Fundamentals: Practical knowledge of securing multi-cloud integrations, including OAuth2, API key management, role-based access control (RBAC), and secrets handling across GCP, Azure, and ServiceNow. Preferred / Nice-to-Have Qualifications Familiarity with Contact Center AI (CCAI) architectures and telephony/voice gateway integrations. Experience with Site Reliability Engineering (SRE) principles, telemetry/observability, and AIOps event correlation. Experience with containerization (Docker, Kubernetes) and serverless deployment models (Cloud Run, Google Cloud Functions, Azure Functions). Tooling & Environment Conversational AI & Cloud: Google Cloud Platform (GECX / Dialogflow CX, Vertex AI), Microsoft Azure Languages & Runtimes: .NET (C#), Python 3.x, Node.js / TypeScript / JavaScript, SQL DevOps & Testing: Azure DevOps (Pipelines, Repos), Git, Automated API/Unit Testing Frameworks Enterprise Platforms: ServiceNow (REST APIs, Flow Designer) Agile Framework: SAFe (Scaled Agile Framework), Jira / Azure Boards Development Environments: Visual Studio Code (VS Code), Antigravity
