• Prompt engineering - zero-shot, few-shot, chain-of-thought, structured output (JSON mode), multi-turnVector databases - working knowledge of OpenSearch, Pinecone, or Faiss; understands vector vs. graph DB difference
• LLM guardrails - input/output filtering, hallucination mitigation strategies Fine-tuning vs. RAG - ability to reason through which approach fits a given problem
• LLM orchestration - LangChain, LangGraph, or Llama Index Embeddings - understands semantic similarity; experience with Amazon Titan Embed or equivalent Python - for Lambda functions, AI pipeline scripting, and data processing
• Java - 3+ years of hands-on test automation development Appium / Ui Automator2 - mobile/Android UI automationAndroid / ADB - device management, test execution ReportPortal or equivalent test reporting tool
• REST API - concepts and hands-on usage Jenkins / CI-CD - pipeline debugging and integration AWS - S3, Lambda, API Gateway, IAM, Ope nSearch Server less Docker - containerized test execution environments

Project Description

• We are building and maintaining one of the largest OTT platform test automation frameworks, serving millions of customers across streaming TV platforms. The team develops a Java/Appium-based automation framework for Android TV devices and is actively expanding it with AI-powered tooling
• We are looking for a Senior AI Developer. This is a hybrid role combining the design and development of AI-powered internal tools with hands-on test automation engineering skills. The ideal candidate is a software engineer who understands both QA automation and modern LLM/RAG systems - and can translate test engineering problems into practical AI solutions

Responsibilities

• Design and implement AI-powered solutions focused on: Automated test failure triage
• LLM + RAG pipeline classifying ReportPortal failures (logs, stack traces, screenshots) into structured categories (PRODUCT_BUG, AUTOMATION_BUG, SYSTEM_ISSUE) using AWS Bedrock +ClaudeAI-based Change-Based Testing (CBT)
• LLM-driven test case selection using semantic similarity between code changes and test coverage AI test case generation from feature specs, Jira tickets, and Confluence documentation
• Develop AWS Lambda functions (Python 3.12) and API Gateway REST endpoints to integrate AI capabilities into CI/CD pipelines
• Apply prompt engineering best practices (system prompts, structured JSON output, guardrails) and drive continuous evaluation of LLM solution accuracy
• Use Cursor IDE with MCP integrations, agentic workflows, and context/rules files to accelerate test code generation and maintenance
• Write, maintain, and expand automated test suites in Java (Appium / UiAutomator2) for Android TV platformsDevelop and maintain functional, regression, NFR, and CBT testsuites
• Triage and resolve test failures in ReportPortal; integrate AI triage results with QMetry (QTM4J)Support CI/CD pipeline health - participate in Nightly Build, RC, and release automation runs via Jenkins
• Contribute to framework codebase improvements - bug fixes, refactoring, enhancements Participate in Kanban ceremonies and PI planning under the ART teamPresent
• AI solution demos to stakeholders and engineering leadershipDocument AI system architecture, RAG pipelines, and tools in Confluence
