Position Purpose: 

We are seeking a motivated AI Engineering intern to support the development and implementation of an AI-powered agent for This role offers hands-on experience with cutting-edge Small language models, cloud infrastructure, and enterprise software development.

Primary Duties/Responsibilities: 

• Small Language Models (SLMs):• Understanding and working with lightweight models such as Phi-3 (Microsoft), Llama(Meta), Mistral (Mistral), Gemma (Google), and TinyLlama (for resource-constrained environments).

• Design Phase:• Requirements Gathering: Using Figma for UI/UX design and workflow planning.
• Data Analysis: Utilizing Jupyter Notebooks and pandas for data exploration, cleaning, and analysis.
• Model Selection: Leveraging Hugging Face Model Hub to compare, select, and download pre-trained models.

• Development Framework:• Core Framework: Building SLM-powered applications using LangChain or Lanngraph for orchestration and workflow management.
• Model Serving: Deploying models locally with Ollama or at scale with vLLM for efficient inference.
• Vector Database: Implementing semantic search and retrieval-augmented generation (RAG) using ChromaDB.
• API Framework: Developing RESTful APIs with FastAPI (Python) or Express.js (Node.js) to expose model functionality

• Development Tools:• IDE: Coding in VS Code, ideally with Python and Copilot extensions for productivity.
• Model Fine-tuning: Customizing models using Hugging Face Transformers and parameter-efficient fine-tuning (PEFT) methods like LoRA/QLoRA.
• Prompt Engineering: Managing and optimizing prompts with LangSmith or PromptLayer.
• Version Control: Tracking code and data changes with Git and DVC (Data Version Control).
• Experiment Tracking: Logging experiments, metrics, and results with MLflow or Weights & Biases.

• Testing Stack:• Unit Testing: Writing and running tests using pytest or unittest to ensure code correctness.
• Model Evaluation: Assessing model performance with RAGAS (for RAG pipelines) and DeepEval.
• Load Testing: Simulating high-traffic scenarios using Locust or Apache JMeter.
• Quality Assurance: Using LangChain Evaluators and custom metrics to ensure output quality and reliability.

• Deployment Stack:• Containerization: Packaging applications with Docker or Docker Compose for portability and reproducibility.
• Orchestration: Managing and scaling containers with Kubernetes (K8s) or Docker Swarm.
• Model Optimization: Accelerating inference and reducing resource usage with ONNX Runtime, OpenVINO, or llama.cpp.
• API Gateway: Managing and securing APIs with Apigee.
• Observability: Monitoring application and model performance with LangSmith.
• CI/CD: Automating build, test, and deployment pipelines with GitHub Actions or GitLab CI.

• Infrastructure Options:• On-Premise: Deploying solutions on local servers with GPU or CPU resources.
• Cloud: Utilizing GCP (Vertex AI) for scalable, managed AI infrastructure.
• Hybrid: Integrating edge devices for local inference with cloud backup for resilience and scalability.
• An intern should be able to demonstrate familiarity with these models, tools, and workflows, as they are essential for designing, developing, testing, deploying, and monitoring efficient, production-ready small language model applications.

Work Environment:

• Environments vary by intership function from office to field to plant.
• Our aim is to provide tangible industry job experience to each intern.

Education/Experience/Background: 

• Working towards a PhD degree and you have in AI/ML/Computer Science.
• 3.8 Cumulative G.P.A required.

Knowledge/Skills/Abilities: 

• Strong communication skills, including written, verbal, listening, presentation and facilitation skills.
• Demonstrated ability to build collaborative relationships.

Pay Range: $21.00 to $25.00 per hour.
