Hiring rubric for a role you've never hired

I'm about to hire a [ROLE]. I've never hired this role before, and I don't have the deep expertise to evaluate candidates well.

Help me build a hiring rubric. Output:

1. **The actual job in one sentence** — strip away the job title and describe what this person needs to do for me to consider the hire a success at 6 months.
2. **Five skill dimensions that matter for #1**, ranked. For each: one sentence on why it matters MORE than the others.
3. **For each skill dimension**, one specific interview question that would surface whether the candidate has it. Avoid "tell me about a time" — give me questions that force a real demonstration.
4. **What "great" looks like for each answer.** Three bullet points per question. Be specific enough that I could grade two candidates and reach the same conclusion as a domain expert would.
5. **One bias I'm likely to make** in evaluating this role given that I'm not a domain expert, and how to counter it.
