What Cloud Builders does

Cloud Builders (クラウドビルダーズ) is a Japan-based online recruitment and job-matching platform focused exclusively on AWS engineering talent, operated by CloudBuilders Inc. (クラウドビルダーズ株式会社) and headquartered in Marunouchi, Chiyoda-ku, Tokyo. The company holds the designation of "AWS Certified Talent Provider Partner" (AWS認定人材提供パートナー) from Amazon Web Services and is described as the only such partner operating a nationwide AWS-specialized job matching platform in Japan. Its core product is the cloudbuilders.jp platform, which connects freelance and full-time AWS engineers — ranging from entry-level IaaS/EC2 practitioners to advanced serverless (Lambda), container (ECS/EKS), and AI-adjacent roles — with hiring companies, supported by AWS-specialist career advisors offering free consultation to candidates.

The platform's product surface includes the main job listing portal categorized by AWS services (60+ services including Lambda, ECS, EKS, S3, RDS, CloudFormation, Terraform), job position types (16 categories from IaaS to CCoE to pre-sales), and keywords (17 tags including full-remote, ¥10M+ salary, AWS novice), plus an AWS technical Q&A community platform, an AWS Engineer Blog for content marketing and SEO, a free consultation signup flow, and enterprise-facing recruitment landing pages. Named employer partners include Classmethod, Classmethod Operations, Cloud Centric, Zeal, and Deloitte Tohmatsu Web Services, with dedicated featured-employer pages surfacing their hiring programs.

The business model is recruitment agency economics: the company acts as an intermediary earning placement commissions from hiring companies, while AWS engineer candidates access consultation and listings for free. Pricing for placement services is not publicly disclosed and is negotiated per engagement. The company is privately held with no disclosed institutional investors, no disclosed revenue or headcount figures, and no disclosed funding history. Geographic scope is limited to Japan.

Direct peers

• Lever Japan: Cloud-focused technical recruitment platform with presence in Japan. Lever (and its Japanese operations) provides engineering talent matching, competing for the same AWS-skilled engineer pool though typically with a broader technical mandate beyond AWS-only specialization.
• Lévtech (レバテック): Lévtech is one of Japan's largest freelance engineer matching platforms operated by Leverages. It directly competes with Cloud Builders for AWS and cloud-skilled engineers in the freelance/contract market segment and is a clear substitute for Cloud Builders' core offering.
• Wantedly: Wantedly is a leading Japanese recruitment platform emphasizing company culture and engineering talent. While broader than AWS-only, it competes for the same engineer audience and offers hiring companies an alternative channel for technical recruiting in Japan.
• Forkwell: Forkwell is a Japanese engineer-focused career and recruitment platform. It overlaps with Cloud Builders on technical talent matching and serves similar engineering personas, though it is broader in technology scope than AWS-specific.
• Green (求人ジャーナル): Green is a Japan-based IT/Web engineer recruitment platform by At Home. It is comparable to Cloud Builders in serving engineer-job-seeker matching but operates as a generalist rather than AWS-specialized competitor.
• クラウドテック (CloudTech) by CrowdWorks: CloudTech is CrowdWorks' engineer-focused freelance matching platform. It competes directly with Cloud Builders in the freelance cloud engineer segment in Japan, though it is not AWS-specialized.

Emerging players

• Classmethod: Classmethod is a Japan-based AWS Premier Consulting Partner that operates its own AWS-focused recruitment and technical blog. It is a featured customer of Cloud Builders but also a potential ecosystem competitor in AWS talent content and community engagement.

Broad incumbents

• BizReach: BizReach is a Japanese incumbent in high-tier direct-hire and executive recruitment. While broader and more focused on senior/experienced hires, it competes for the same high-salary engineering talent segment that Cloud Builders addresses.
