Why we read it this way (5)
The title reads 'Sr. Staff Software Engineer', which is treated as Staff-level — the role carries genuine cross-team technical direction, platform-level ownership, and mentorship responsibilities consistent with that band.
Recoil is listed alongside 'state management libraries like Recoil', implying it as the primary example; marked required as it appears under Minimum Qualifications.
D3.js and Next.js are listed together as 'visualization tools like D3.js or Next.js' under Preferred Qualifications — they serve different purposes (charting vs. framework), but the posting groups them as interchangeable preferred extras, so they are captured together with D3.js as primary.
No compensation range is stated in the posting.
The role is hybrid (San Jose, CA office required), not fully remote.
