Why we read it this way (8)
The job title is 'Principal Technical Support Engineer' and the role sits in the Customer Service & Support org, but the actual responsibilities described — causal inference, ML framework architecture, LLM evaluation, executive advisory on measurement strategy, and mentoring data scientists — are squarely data science work, not technical support. The title appears to be an internal Microsoft leveling label (IC6) rather than a description of the work.
The SOC classification reflects the actual day-to-day work (data science / causal inference / ML) rather than the job title. 15-1211 Computer Systems Analysts is listed as an alternative given the technical support framing of the title and minimum qualifications.
The minimum qualification requires a Bachelor's degree; however, the JD also accepts 'equivalent experience' in lieu of the degree. Degree requirement is set to Bachelors because the JD does not clearly make equivalent experience a full substitute — it uses 'AND … OR equivalent experience' phrasing that is ambiguous, but the degree is the primary stated gate.
U.S. citizenship verification is required (via valid passport) due to the role supporting U.S. federal/state/local government customers. This is a citizenship verification requirement, not a security clearance gate, so clearance is set to None.
The base pay range of $165,600–$303,600/year applies specifically to the San Francisco Bay Area and New York City metro areas; the general U.S. range of $130,900–$277,200/year is used here.
The location is not explicitly stated in the posting beyond 'across the U.S.' Microsoft's CSS/CE&S headquarters is in Redmond, WA; the CBSA is set to Seattle-Tacoma-Bellevue as the most likely primary location, but this is an inference.
Seniority is assessed as Senior despite the 'Principal' title: the 10+ year minimum requirement and the scope described (org-level vision, executive advisory) are consistent with a Senior/Staff IC role at most companies. Microsoft's IC6 level internally maps to Principal, but by external labor-market standards the candidate pool is Senior-level.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): large-scale experimentation platforms.
