Work closely with the Director of AI on the development of AI agents, copilots, and intelligent automation tools
Assist in building, testing, and fine-tuning large language models and retrieval-augmented generation (RAG) pipelines
Contribute to prompt engineering and integration of LLMs into web-based or API-driven applications
Support data preprocessing, embedding, and vector database structuring (e.g., Pinecone, Weaviate)
Write clean, testable Python code and support REST API integrations
Participate in QA testing, performance benchmarking, and debugging AI system behavior
Stay updated on emerging tools, frameworks, and trends in the AI ecosystem
Collaborate with cross-functional teams including DevOps, cloud engineers, and UI/UX designers

Foundational knowledge in machine learning and NLP principles
Proficiency in Python and familiarity with ML libraries like scikit-learn, PyTorch, or TensorFlow
Understanding of APIs, JSON, Git-based version control, and cloud fundamentals
Excellent problem-solving skills and attention to detail
Willingness to work on-site full-time in our Ottawa office (this is not a hybrid or remote role)

Bonus Skills (Assets)

Exposure to LLMs such as OpenAI, Claude, Mistral, or LLaMA
Experience with LangChain, Hugging Face Transformers, or similar frameworks
Basic experience with vector databases or embedding models
Familiarity with Azure, AWS, or GCP
Interest in chatbot development or knowledge-based search applications

An innovative and supportive team environment inside one of Ottawa’s leading IT firms
