What Companies Use AWS?

What companies use AWS? No public register answers that, but job postings come close: an employer advertising for AWS skills is running it, migrating to it or building on it for clients. Below is the current list read from active postings, the industry and size mix behind it, and the query that rebuilds the list whenever you need it.

The employers with the most active postings naming AWS, as of 2026-09-09:

• Amazon.com
• Amazon Web Services
• JPMorganChase
• EPAM Systems
• Capgemini
• Deloitte
• HCLTech
• EY
• Accenture
• NTT DATA

Vendors sit on their own list, because a provider’s postings name its products constantly, and consultancies and staffing firms rank high because they hire for client stacks rather than their own. The full list, with company domains and the country split, is on the companies using AWS page.

How to find out what companies use AWS yourself

1. Search postings by skill. Call POST /v1/jobs/search with skills_or set to ["aws"]. Every row carries company and a technology_slugs array, so grouping the results by company and sorting by open roles produces the list above.
2. Read the roles, not just the count. A platform engineer posting means the company runs AWS. A solutions architect posting at a consultancy means it sells AWS work. A single mention in a nice-to-have line means little. Filter with job_title_or to keep the roles that prove adoption.
3. Cut by industry and size. Add isic_division_or for an industry and min_employee_count or max_employee_count for a size band. The chart below shows where postings naming AWS concentrate.
4. Confirm on the website. POST /v1/stack/scan reads a domain’s public site for hostnames, headers and scripts. AWS shows up when the site itself is served from it, so a scan and the hiring record confirm each other. A company can run AWS behind the scenes while its marketing site sits on a different host, which is why the posting signal matters.
5. Keep the list live. Rerun the query with discovered_at_gte set to your last check, or save it as a Signal. A first AWS posting at a company that never named it before is the earliest public sign of a migration.

How many companies use AWS? Posting data cannot count companies, only postings, and it puts the answer in perspective: 3.1% of active postings on the ten collected boards name AWS. That is a minority of postings, because most roles at an AWS shop never mention the cloud provider. The figure measures hiring that names AWS, not the share of companies that run it.

Where JobsPipe fits

JobsPipe is a jobs data API that collects live postings from LinkedIn, Indeed, Y Combinator, Naukri, Workday, Greenhouse, Workable, SmartRecruiters, Ashby, Lever and Paylocity, returns them as one schema with closure tracking and a ghost score, and includes a free tier of 1,000 jobs a month. The list above is one request against jobspipe.dev:

curl -X POST https://api.jobspipe.dev/v1/jobs/search \
  -H "Authorization: Bearer $JOBSPIPE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "skills_or": ["aws"], "status": "active", "limit": 100 }'

Group the rows by company and you have the list; read technology_slugs and you have the rest of each employer’s stack. The website side is the stack scan, and how the two signals combine is explained on the technographics page.
