AI Engineer – Generative AI

Details: Job Description

We are seeking an experienced AI Engineer with 3-6 years of hands-on experience designing, developing, and deploying generative AI applications in production environments. The candidate will be responsible for building intelligent, AI-powered features - including text generation, summarization, conversational AI, and agentic workflows - and integrating them securely into scalable, cloud-based backend systems.

The role requires a strong foundation in large language model (LLM) systems, including prompt engineering, retrieval-augmented generation (RAG), agent orchestration, and output evaluation, combined with solid backend development expertise. Experience with the Google AI ecosystem (Gemini API, Vertex AI, Agent Development Kit) is an advantage; candidates with equivalent experience on other major LLM platforms are encouraged to apply.

Key Responsibilities

• Design, develop, and deploy generative AI features such as text generation, summarization, conversational assistants, and multi-step agentic workflows.
• Architect and implement retrieval-augmented generation (RAG) pipelines, covering document ingestion, chunking, embeddings, vector store integration, retrieval and reranking, and grounding quality assessment.
• Develop agentic systems using tool/function calling, structured outputs, and orchestration patterns, incorporating appropriate guardrails, fallback mechanisms, and human-in-the-loop controls.
• Establish and maintain prompt engineering standards, including prompt versioning, structured output schemas, and data-driven optimization of response quality and accuracy.
• Build evaluation frameworks for LLM outputs, including curated test datasets, automated evaluations, regression testing, and monitoring for hallucination and grounding quality.
• Integrate AI services into backend applications through well-designed REST APIs and microservices, with robust handling of structured JSON responses, streaming, retries, and error states.
• Implement secure API authentication and access management for AI services, including API key management, OAuth 2.0, IAM, secrets handling, and safeguards against prompt injection and data leakage.
• Monitor and optimize production performance across response latency, token cost, throughput, and output quality, supported by appropriate observability and tracing.
• Collaborate with product managers, data engineers, and application developers to embed AI capabilities into business applications while ensuring security, reliability, and compliance.

Job Requirements

Details:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
• 3-6 years of experience in AI/software engineering, including hands-on delivery of LLM-powered applications in production.
• Strong understanding of LLM fundamentals, including transformer architecture, tokenization, context windows, embeddings, sampling parameters, and the trade-offs between prompting, RAG, and fine-tuning.
• Working knowledge of common LLM failure modes (e.g., hallucination, prompt sensitivity, context degradation) and corresponding mitigation strategies.
• Hands-on experience with one or more major LLM platforms, such as Google Gemini, OpenAI, Anthropic Claude, or open-source models (Hugging Face, vLLM).
• Practical experience building RAG systems, including chunking strategies, embedding models, vector databases (e.g., pgvector, Pinecone, Weaviate, Vertex AI Vector Search), and retrieval evaluation.
• Experience implementing tool/function calling and agentic workflows, using frameworks such as LangGraph, LangChain, Google ADK, or CrewAI, or through custom implementations.
• Proficiency in prompt engineering, supported by structured evaluation of output quality.
• Strong programming skills in Python; experience with Node.js or similar backend technologies is a plus.
• Solid backend engineering fundamentals, including REST API design, microservices architecture, and scalable, fault-tolerant system design.
• Experience integrating AI services within cloud architectures (GCP, AWS, or Azure), including secure API authentication and structured JSON response handling.

Preferred Qualifications

• Direct experience with the Google AI ecosystem, including Gemini API, Vertex AI, Google Agent Development Kit (ADK), or Google Antigravity.
• Experience with the Model Context Protocol (MCP) or building tool integratio…
