Why we read it this way (4)
No location is specified in the posting; CBSA and state are left blank. The role may be remote or in-person at an unstated office — remote is conservatively set to false given no explicit remote claim.
No experience level or years of experience are stated anywhere in the posting; seniority is inferred as Mid based on the scope of responsibilities (full-stack contribution, working closely with CTO/engineering leadership at a startup) without explicit senior-level ownership signals.
All named technologies appear in the Responsibilities section as part of the described stack ('TypeScript + React, NestJS + Postgres + Prisma, AWS', 'SQS/SNS/Lambda', 'Docker'). They are treated as hard gates given their placement in the primary responsibilities block. Vercel is mentioned parenthetically alongside the AWS services and Docker, with less emphasis, so it is marked preferred.
No compensation, degree requirement, or employment type is stated in the posting.
