Gen AI Engineer

We are looking for an enthusiastic Senior GenAI Engineer to drive our generative AI initiatives, with a strong focus on building GenAI utilities that elevate Quality Assurance practices and accelerate developer productivity across the engineering organisation.

You will design, build, and operationalise LLM-powered tools, agents, and platforms on AWS that are secure, scalable, and production-ready in a regulated environment.

Key Responsibilities

• You will be #LI-hybrid based in Hyderabad and reporting to Director Engineering
• Work as a senior GenAI engineer in an agile team to deliver high-quality, production-grade GenAI solutions within agreed timelines, aligned with business requirements and agile principles.
• Design and build GenAI-powered utilities for QA - including intelligent test case generation, test data synthesis, automated defect triage, log/anomaly summarization, and assistive code/test review tooling - to measurably improve quality and engineering velocity.
• Develop reusable GenAI accelerators, libraries, and internal copilots that increase productivity across software engineering, QA, and operations teams.
• Translate business and engineering requirements into clean, scalable Python code, applying design patterns, secure coding practices, and modern LLM application architectures (RAG, tool-use, agents).
• Build and operate LLM applications on AWS using services such as Amazon Bedrock, SageMaker, Lambda, ECS/EKS, API Gateway, S3, DynamoDB, and OpenSearch.
• Establish patterns and frameworks for prompt engineering, retrieval-augmented generation, evaluation, observability, and continuous improvement of GenAI systems.
• Champion responsible AI - guardrails, PII protection, model governance, hallucination mitigation, and compliance with security and regulatory requirements.
• Collaborate closely with cross-functional team members - QA engineers, software engineers, architects, product, and security - to design, develop, test, and release GenAI-powered software.
• Contribute to development processes and practices, fostering a culture of continuous integration, delivery, evaluation, and improvement for GenAI systems.
• Provide clear and concise documentation for prompts, models, datasets, code, processes, and system architecture to support knowledge sharing and maintainability.

• Bachelor's degree in engineering or a related discipline.
• 3+ years of hands-on experience in software development, with at least 1+ years working on production GenAI / LLM-based applications.
• Proven experience building secure, high-volume, mission-critical systems in regulated industries (finance / insurance / healthcare).
• Expertise in translating business requirements into clean, scalable code using design patterns and security best practices.
• Strong individual contributor and effective team collaborator, comfortable working with QA, engineering, and product stakeholders.

Technical Skills

• Strong Python development skills - building production services with frameworks such as FastAPI / Flask, Pydantic, asyncio, and modern packaging/testing tooling.
• Hands-on expertise with AWS for designing, deploying, and operating applications - Bedrock, SageMaker, Lambda, ECS/EKS, API Gateway, S3, DynamoDB, OpenSearch, IAM, CloudWatch, Step Functions.
• Strong working knowledge of GenAI fundamentals - LLMs (Claude, GPT, Llama, Mistral and similar), embeddings, tokenisation, context windows, model selection, and cost/performance trade-offs.
• Experience designing and shipping Retrieval-Augmented Generation (RAG) solutions using vector stores (OpenSearch, pgvector, Pinecone, FAISS) and hybrid retrieval patterns.
• Practical experience with prompt engineering, structured outputs, function/tool calling, and agentic patterns; familiarity with frameworks such as LangChain, LlamaIndex, Bedrock Agents, or similar.
• Experience defining and running LLM evaluation frameworks - golden datasets, automated evals, regression testing, and online metrics for quality, safety, and cost.
• Building and consuming REST / gRPC APIs using microservices / SOA, with strong API design, versioning, and security practices.
• Experience writing unit and integration tests (pytest), applying TDD, and building eval harnesses for LLM-based components.
• Expertise in creating, maintaining, and reusing frameworks / libraries for GenAI utilities and shared platform capabilities.
• Experience with model fine-tuning and parameter-efficient techniques (LoRA, QLoRA), distillation, and small-language-model deployment.
• Experience with agentic frameworks, multi-agent orchestration, and emerging standards such as Model Context Protocol (MCP).
• Clean code, clean architecture, SOLID principles, and design patterns applied to data- and ML-intensive systems.
• Expertise with SQL / NoSQL databases (PostgreSQL, DynamoDB, MongoDB) for application and feature/metadata storage.
• Proficient with Docker, Kubernetes, and Git (Bitbucket, GitHub, GitLab) and CI/CD practices.
• Experience working in Agile teams (Scrum or Kanban).
• Familiar with static code analysis, dependency scanning, and vulnerability management for AI/ML applications.

Desirable Skills

• Demonstrable experience building GenAI utilities or copilots for QA and/or developer productivity (test generation, defect triage, code/test review assistants, documentation generation).
• AWS certifications - especially AWS Certified Machine Learning - Specialty, AI Practitioner, Solutions Architect, or Developer Associate.
• Experience deploying and scaling services on Amazon ECS / EKS and serverless GenAI architectures.
• Working knowledge of GenAI tools for coding (e.g., GitHub Copilot, Amazon Q Developer, Claude Code).
• Familiarity with Domain-Driven Design (DDD) and Event-Driven Architecture (EDA).
• Event streaming / messaging tools (Kafka, EventBridge, Kinesis, RabbitMQ, ActiveMQ).
• Proficient in Infrastructure as Code (IaC) using Terraform, CloudFormation, or AWS CDK.
• CI/CD tools such as GitHub Actions, GitLab CI, or Jenkins, with experience building MLOps / LLMOps pipelines.
• Experience with LLM observability and evaluation tooling (LangSmith, LangFuse, RAGAS, Helicone, Arize) and responsible-AI guardrails.
