- Strong communication and stakeholder engagement skills.
- A Master’s degree in Computer Science, ML, or AI is preferred but not required.
The Opportunity
- Be part of an ambitious AI journey - already 70% built, with big plans for the next 5 years.
- Contribute to short-term LLM “quick wins” and longer-term agentic AI development.
- Work in a collaborative, supportive environment with senior data leaders.
- Help shape how AI transforms both customer experience and business efficiency.
