Join our team
This is an exciting opportunity to join the CSD AI Innovation Hub within Customer Solutions Delivery (CSD). We are a dynamic and agile team revolutionizing field operations by designing data-driven AI solutions that optimize OpEx, CX, sales, billing, and other key metrics across our national technician workforce. Our AI Hub is the go-to destination for autonomous, creative professionals passionate about developing their talents while solving some of TELUS's most significant challenges.
As part of our team, you'll contribute to high-visibility programs that are transforming the telecommunications business model.
What you’ll do
As a Senior Data Scientist focused on delivering generative AI solutions, you will work cross-functionally to discover high-impact opportunities, tapping into diverse data sources to drive innovation across the business. Drawing on your expertise as a data scientist and a strong foundation in data engineering and software development, you’ll architect and implement scalable, end-to-end AI systems that support faster, smarter decision-making and accelerate enterprise AI adoption.
Your responsibilities will include:
- Design and deploy GenAI solutions (RAG, summarization, classification, intelligent agents) tailored to internal business needs
- Fine-tune open-source and proprietary foundation models (OpenAI, Claude, Mistral, LLaMA) on TELUS-specific data
- Integrate LLMs and multimodal models into production systems in collaboration with data engineers and developers
- Apply prompt optimization techniques (e.g., compression, chain-of-thought, few-shot, tool use) to balance cost, latency, and performance
- Evaluate model outputs using qualitative and quantitative methods (BLEU, human-in-the-loop feedback)
- Translate complex business problems into scalable, responsible GenAI and ML-driven solutions
- Contribute to internal tooling, standards, and reusable components for accelerating GenAI adoption at TELUS
- Maintain working knowledge of classical ML techniques (regression, clustering, tree-based models) for hybrid solution development
Qualifications
What you bring
- Master’s degree in CS, Machine Learning, Data Science — or a PhD in a relevant discipline
- 3+ years of experience applying ML/AI in business or production environments
- Proven expertise in working with modern LLMs (e.g., GPT-4, Claude, LLaMA, Falcon, etc.)
- Hands-on experience with vector search and RAG architectures
- Familiarity with fine-tuning tools and techniques (e.g., LoRA, PEFT, DeepSpeed, etc.)
- Strong development experience with Python and proficiency with data science libraries (Scikit-learn, Pandas, Numpy) and frameworks like TensorFlow, PyTorch, and Keras
- Solid understanding of MLOps best practices and model deployment via GCP (Vertex AI, Cloud Functions, Pub/Sub, etc.)
- Comfort working with unstructured data (text, PDFs, transcripts, emails) and embedding techniques (OpenAI)
- You are agile and have a bias for action, removing roadblocks to get results fast
- Excellent communication and documentation skills for both technical and non-technical audiences
