\- Exceptional depth in one area you care deeply about, shown through things like following AI developments, working with language models or open-source contributions.

\- Skill at describing technical choices in plain language to people outside engineering, and willingness to think aloud while solving problems.

\- A team-first attitude suited to a small, tightly knit group.

\- Meticulous habits and real pride in delivering polished, high-quality work.

\- A hands-on, accountable mindset with readiness to take on any task that moves the team forward.
