Why we read it this way (5)
The posting contains two conflicting salary ranges: '$180,000–$200,000' is stated in the Pay Transparency section, while '$140,000–$170,000 a year' appears at the very end of the posting. The higher range ($180,000–$200,000) is presented as the official, named compensation figure and is used here; the lower figure may be a remnant from a prior draft or a different role level.
The role is titled 'Staff Fullstack Engineer' but the requirements section does not describe org-wide technical authority or cross-team direction-setting typical of a Staff band — it reads more like a strong Senior IC with some mentoring responsibilities. Seniority is assessed as Senior accordingly.
Cloud infrastructure and containerized environments (Docker/Kubernetes) appear only under 'Nice to Have' and are marked preferred.
React and other modern frontend frameworks appear only under 'Nice to Have' and are marked preferred.
Experience working alongside ML/AI teams and building developer platforms or enterprise products also appear under 'Nice to Have' but name no specific technology, so they are omitted from the skills list per extraction rules.
