Why we read it this way (8)
The title is 'Principal Backend Engineer' and the JD explicitly frames this as a Principal-level individual contributor role with org-wide technical influence — seniority is assessed as Principal, not merely Senior.
The degree requirement states 'Bachelor's degree … or equivalent practical experience,' so no formal degree is hard-gated.
The Required Tech Stack section lists Go, Rust, Python, Java (or similar) as a group; Go is named first and is the company's primary backend language based on context, so it is used as the canonical skill name with the others as alternatives.
REST/API design is inferred as a hard gate from the Required Tech Stack's 'Designing and operating APIs, services, and asynchronous or event-driven systems' — no single named protocol is called out, but REST is the canonical form for this type of backend API work.
PostgreSQL, Neo4j, GraphQL, Airflow, and observability tools (Datadog/Prometheus/Grafana) all appear exclusively under 'Preferred Education/Experience' and are marked accordingly.
Equity (stock options) is offered in addition to the stated base salary range but is not quantified; it is noted here for the hiring manager's awareness.
Up to 10% travel is required despite the fully-remote designation — primarily for team kickoffs and annual company gatherings.
Caller marked this a fully-remote role — scored against the national candidate pool.
