Why we read it this way (5)

The title 'Backend Engineer' carries no explicit seniority level, so advertised seniority is Unspecified; however, the requirements gate on 5+ years of industry experience and deep domain expertise, supporting a Senior classification.

The backend language requirement names Java and Python as examples ('e.g. Java, Python'), indicating these are interchangeable options for the same requirement — captured as one skill with alternatives.

Financial systems / reconciliation workflows / data integrity is listed under 'Nice to have' but names no specific technology or tool, so it was omitted from the skills list per extraction rules.

ML pipelines and feature stores appear under 'Nice to have'; 'feature stores' is a concept rather than a named tool, so only 'ML pipelines' is captured as a preferred skill.

This role is 5 days a week in-office in San Francisco — not remote.
