The full list on this page names 41 companies. ### How does JobsPipe know a company uses TCP/IP? From the company's own job postings. Each posting is read for the technologies it names, and every company and technology pair is graded: confirmed when two independent checks agree on TCP/IP in at least one posting, likely when it is a stated requirement or appears in two separate postings. A single passing mention is not counted here. It is evidence of a team working with TCP/IP, not a purchase record. ## Reproduce ```bash curl -X POST https://api.jobspipe.dev/v1/companies/search -H "Authorization: Bearer $JOBSPIPE_API_KEY" -H "Content-Type: application/json" -d '{"company_technology_slug_or":["tcp-ip"],"tier_min":"confirmed","company_country_code_or":["US"],"limit":25}' ``` --- AI agents: the full machine-readable index of this site is https://jobspipe.dev/llms.txt?src=md-twin - API quickstart, no-key sandbox (POST https://api.jobspipe.dev/v1/sandbox/jobs/search), MCP server, pricing.
