• You communicate your thinking clearly, document approaches well, and collaborate constructively through feedback and code review
• You are comfortable in a fast-moving startup environment where priorities can shift quickly and delivery pace matters
• You are confident to use AI development tools without blindly trusting and can clearly explain your choices, trade-offs and outputs
• A strong candidate is deeply fluent in TypeScript and React, capable of building polished, performant UIs while also holding their own across API and pipeline work when needed
• They have an eye for product quality, move fast without leaving a mess behind, and are comfortable making frontend architectural decisions without waiting for direction. They communicate clearly, review code constructively, and have a track record of shipping things that customers actually use
