Why we read it this way (7)
The role is titled 'Senior Staff (P5)' — Mozilla's internal P5 level maps to Staff on the standard career ladder, and the JD describes org-wide analytical leadership, executive partnership, and cross-team mentorship, which supports a Staff classification.
Compensation is tiered by US geography: Tier 1 $163,000–$218,000, Tier 2 $150,000–$200,000, Tier 3 $139,000–$185,000. The Tier 1 range is reported in the comp fields as it represents the highest band; hiring managers should note the lower tiers apply to most US locations.
The posting is fully remote (#LI-REMOTE) with no primary metro; no CBSA is assigned.
Python and R are listed as interchangeable ('Python or R') in the requirements section; Python is captured as the primary with R as an alternative.
'Modern data science tooling' is mentioned in the requirements but names no specific tools beyond Python/R and SQL, so no additional tool skills are emitted.
No minimum total years of experience is stated anywhere in the posting.
This posting reads as a fully-remote role, so it was scored against the national candidate pool rather than a single metro.
