What this job asks for AI summary
A senior individual-contributor data science role embedded in a CoreAI organization, focused on delivering executive-level analyses that inform major investment decisions. The position spans the full data-science lifecycle — experiment design, causal inference, large-scale modeling, pipeline contribution, and operationalization of reports and models — while also mentoring data scientists, engineers, and PMs and helping scale the team's data infrastructure and culture.
Senior level · 7+ years

Why we read it this way (6)
The posting lists SQL, Python, and R as interchangeable options for the large-scale data analysis requirement ('SQL, Python, or R') — all three are captured as a single mutual-alternative group rather than separate hard gates.
The degree requirement is effectively None: the posting accepts a Doctorate + 3 yrs, a Master's + 5 yrs, a Bachelor's + 7 yrs, OR equivalent experience, so no specific degree is a hard gate.
The overall years minimum is set to 7, reflecting the lowest-degree pathway (Bachelor's + 7 years); candidates with advanced degrees and fewer years also qualify.
The posting contains an unusual phrase — 'These requirements include, but are not limited to the following specialized security screenings' — which appears to be boilerplate or a copy-paste artifact; no actual security clearance is described or required.
The role title is not given; 'Unspecified' is used for advertised seniority. The actual scope (executive-facing, mentoring, 5+ years leading projects) firmly supports a Senior classification.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): experiment design.
