Why we read it this way (8)
The posting explicitly targets 'junior and mid-level engineers' and states React experience is the primary gate, with at least 1 year of backend experience in any language. The 3+ years figure is tied specifically to React, not overall experience — the overall years minimum is set to 3 to reflect that React-specific gate as the dominant experience floor.
Seniority is assessed as Mid: the posting explicitly invites junior and mid-level candidates, but the 3+ years React requirement and end-to-end ownership expectations push the realistic pool toward Mid rather than Junior.
Backend languages (Ruby on Rails, Java) are explicitly stated as not required — willingness to learn is sufficient. They are captured as preferred, with Ruby on Rails and Java listed as alternatives of each other since either satisfies the same backend familiarity signal.
Jest and Cypress appear in the requirements section but are qualified as 'familiarity with common testing tools such as Jest and Cypress' — the 'such as' framing makes these illustrative examples of a testing-familiarity requirement rather than hard gates on those specific tools, so they are marked preferred.
All backend stack technologies (Kafka, Kubernetes, GCP, PostgreSQL, Redis, Snowflake, BigQuery, Apache Airflow, gRPC, Storybook, SCSS) appear only in the 'Tech stack' narrative section, not in the requirements block, and are marked preferred accordingly.
No compensation figures are disclosed in the posting.
A CS degree or equivalent experience is accepted, so the degree requirement is set to None.
