Job description

At CI, we see a great place to work as one that is a safe place for everyone to have a voice, where people are empowered to take ownership over meaningful work, where there is an opportunity to grow through stretching themselves, where they can work on innovative products and projects, and where employees are supported and engaged in doing so.

CI Financial isseekingan experienced and technically strongSenior AI Engineerto join our Data, AI & Analytics (DNA) team. This role focuses on theapplied use of Generative AI and Agentic AI,leveragingexisting large language models (LLMs) and platforms-not building models from scratch. As a senior member of the team, you'll take technical ownership of intelligent applications and automation tools that use LLMs to solve business problems, set best practices for the team, and mentor junior engineers, while partnering closely with business, engineering, and governance stakeholders to bring production-grade AI solutions to life.

KEY RESPONSIBILITIES:

Applied Generative & Agentic AI:

You'llbe building the agents and GenAI systems that CI's advisors, analysts, and operations teamsactually relyon day to day - not prototypes that stall out after the demo.

  • Architect and build production-grade intelligent systems and applications using existing LLMs (e.g., OpenAI, Claude, Gemini, etc.) through API integration, prompt engineering, fine-tuning, or Retrieval-Augmented Generation (RAG).

  • Design, prototype, and lead development of agentic AI systems capable of multi-step reasoning, task decomposition, and tooluseto automate and support complex business workflows.

  • Contribute to the design of a reusable, scalable AI platform (shared tooling, agent frameworks, and infrastructure) rather than one-off point solutions, so capabilities can be reused across use cases.

  • Building web app AI solutions using frameworks such as React orStreamlit.

Monitoring & Improvement:

  • Set technical direction and best practices for GenAI and agentic solution design, including evaluationmethodology, guardrails, and reliability of LLM-powered systems.

  • Drive continuous iteration and improvement of models and LLM-powered tools based on performance metrics, cost, and user feedback.

Technical Leadership & Best Practices:

  • Lead design and code reviews, championing best practices around experimentation, reproducibility, and responsible AI.

QUALIFICATIONS:

Education:

  • Bachelor's orMaster's degree in Computer Science, Data Science, AI, Machine Learning, Statistics, or a related field.

Experience:

  • 4-8+ years of experience in a data science, machine learning, or AI engineering role, including hands-on experience delivering production systems.

  • Demonstrated experience designing, building, and shipping agentic AI systems involving multi-step reasoning, task decomposition, and tool use.

  • Experience designing around real-world infrastructure limitations-such as rate limits, quota management, retries/backoff, and cost-per-call-when architecting LLM-powered systems at scale.

Skills:

  • Deep understanding of prompt engineering, RAG, fine-tuning, and evaluation of generative output, includingtradeoffsacross approaches.

  • Proficiencyin Python and ML/AI libraries (e.g., Scikit-learn,PyTorch, TensorFlow).

  • Hands-on skills in designing and orchestrating agentic workflows (multi-step reasoning, task decomposition, tool/function calling).

  • Excellent communication skills; able to present complex technical concepts clearly to both technical and non-technical stakeholders, including senior leadership.

  • Experience with cloud-based environments (AWS, Azure, or GCP).
