Why we read it this way (5)
The title 'Frontend Engineer' carries no seniority level, so advertised seniority is Unspecified; however, the 5+ years requirement in a Kubernetes infrastructure environment and the breadth of hard-required skills support a Senior classification.
SOC confidence is Medium: the role is titled Frontend Engineer and ships a UI application (pointing to 15-1252 Software Developers), but the unusually deep Kubernetes/infrastructure requirements and Go proficiency make it a genuine hybrid. 15-1254 Web Developers is listed as the runner-up only because of the frontend framing, though the application complexity clearly favors 15-1252.
The '5+ years of production experience in a Kubernetes-based infrastructure environment' is stated as a role-level requirement, not tied to a single named technology, so it is captured as the overall years minimum rather than as a per-skill years demanded — though Kubernetes is the primary named technology in that sentence.
gRPC is mentioned in the 'What You'll Do' narrative (integrating with gRPC/cRPC backends) rather than in the explicit Required section; however, given the role's deep infrastructure integration mandate and the firm language around backend API work, it is treated as a contextual hard requirement. Hiring managers should note this is a judgment call.
The posting explicitly states this is on-site in San Francisco, CA with no visa sponsorship available.
