Mid-Size US Tech Hiring List

I need reliable, up-to-date research on U.S.–based, medium-sized technology companies that are actively hiring so I can target them for my own job applications. The focus is exclusively on tech firms with roughly 100–1,000 employees; startups that are still very small or giants like Google or Microsoft can be skipped.

Please research across LinkedIn, Indeed, company career pages, and comparable sources, then compile a clean spreadsheet that includes for each company:
• company name and headquarters city/state
• estimated employee count (or range)
• open technical roles posted within the last 30 days with job titles and links
• date the role was first listed
• direct URL to the firm’s careers page
• a brief note if the company is remote-friendly or hybrid

I will consider the work complete when the spreadsheet contains at least 50 unique companies meeting all of the above points, with every link working and every posting verified as currently open.
