- Collaborate closely with the AI Platform team to
- leverage
- shared infrastructure, align on technical architecture, and get guidance on the AI stack.

Build from the ground up
Join us at the beginning of this journey, working closely with the team
Lead
to shape the strategy, culture, and technical foundations of our new team.
You will be the bridge between business teams and AI solutions.
That means sitting with non-technical stakeholders, asking the right questions, mapping their workflows, and translating messy real-world problems into clear requirements before a single line of code is written. You're as much a translator and trusted partner to the business as you are an engineer.
