Job Summary:

One of our client is looking for an AI Engineer to design, build, deploy, and maintain production-grade AI and Generative AI applications. The ideal candidate combines strong software engineering fundamentals with hands-on experience building solutions using Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), AI agents, machine learning, and cloud technologies.

You will work closely with product, engineering, data, and business teams to translate real-world problems into scalable, reliable AI solutions.

Key Responsibilities:

  • Design and develop AI/ML and Generative AI applications for business use cases.
  • Build LLM-powered applications using APIs and/or open-source models.
  • Develop RAG pipelines, embeddings, vector search, and knowledge-retrieval systems.
  • Design and implement AI agents, tool calling, workflows, and orchestration.
  • Develop prompts, structured outputs, guardrails, and fallback mechanisms.
  • Build evaluation frameworks to measure accuracy, relevance, reliability, latency, and cost.
  • Integrate AI capabilities into existing web applications, APIs, and enterprise systems.
  • Develop and deploy scalable AI services using Python and modern backend frameworks.
  • Fine-tune or adapt ML/LLM models when appropriate for the use case.
  • Implement monitoring, logging, testing, and observability for AI applications.
  • Optimize model performance, inference latency, token usage, and infrastructure costs.
  • Work with cloud platforms such as AWS, Azure, or GCP.
  • Collaborate with data scientists and software engineers on end-to-end AI solutions.
  • Stay current with developments in LLMs, GenAI, ML frameworks, and AI engineering practices.

Required Qualifications:

  • Bachelor's or Master's degree in Computer Science, AI, Machine Learning, Data Science, Engineering, or a related field.
  • 5+ years of software/AI/ML engineering experience.
  • Strong Python programming skills.
  • Experience developing and deploying AI/ML applications.
  • Hands-on experience with LLMs and Generative AI.
  • Experience with RAG, embeddings, vector databases, or semantic search.
  • Understanding of machine learning and deep learning fundamentals.
  • Experience building REST APIs and integrating third-party services.
  • Experience with Git, Docker, CI/CD, and software development best practices.
  • Experience with at least one major cloud platform: AWS, Azure, or GCP.
  • Strong problem-solving, communication, and collaboration skills.

Technical Skills:

Languages: Python, SQL, JavaScript/TypeScript

AI/ML: Machine Learning, Deep Learning, NLP, LLMs, Generative AI, RAG, Fine-tuning
