- Partner with product managers and designers to clarify requirements and shape the roadmap.
- Proactively identify and resolve bugs, performance bottlenecks, and optimization opportunities.

We expect every team member to actively use AI in their day-to-day work, identify where AI can change the shape of problems in their function, and grow their fluency as the tools evolve. You should already be using AI meaningfully in your work and understand where it adds value and how it can improve the way you operate.
