Why we read it this way (8)
The role title carries no seniority level word, so advertised seniority is Unspecified; however, the 8+ years requirement and full product ownership scope firmly support a Senior classification.
React, NextJS, and TypeScript are listed together under 'technologies like … or similar' in the requirements section — they are treated as a hard gate on the capability (high-performance web application development), with the named tools being interchangeable alternatives of each other. Each is also emitted separately because the posting names all three explicitly.
Web Workers and OPFS-backed caching are called out explicitly in the requirements narrative as techniques the role must employ; they are treated as hard gates on browser performance knowledge.
All 'Bonus Points' items (LLMs, Tailwind, Radix UI, WebGL, D3.js, Apache ECharts, WebAssembly, scientific computing background) are explicitly under a secondary 'Bonus Points' heading and are marked preferred.
Stack technologies listed under 'Relevant technologies include' (Redux, Go, Kafka, DuckDB, Docker, Kubernetes, Terraform, GitHub Actions, AWS, Azure, GCP, etc.) appear only in the team-stack narrative section and are marked preferred.
The posting requires U.S. person status (ITAR/EAR compliance) but does not gate on a US government security clearance — clearance is set to None.
The role is hybrid (in-person twice a week in Marina Del Rey, CA, with an SF office option), not fully remote.
A San Francisco office option is mentioned for the right candidate, but the primary/headquarters location is Marina Del Rey (Los Angeles metro), so the CBSA reflects Los Angeles.
