Today, recruitment agencies in the US provide services ranging from temporary staffing and permanent placement to executive search and workforce consulting. The market includes global staffing firms, specialized agencies focused on high-demand sectors, and international providers that support cross-border hiring.
Top recruitment agencies in the United States used by companies to simplify hiring include Robert Half, Korn Ferry, Adecco, ManpowerGroup, Randstad, and INS Global, but which is best will depend on the situation or specific need.
Recruitment Market Overview in the United States
A combination of economic scale, labor mobility, and sectoral diversity drives the US recruitment market, where employers in the United States frequently rely on recruitment agencies to reduce time-to-hire, access pre-screened candidates, and manage flexible workforce needs.
In a general sense, job openings continue to rise across the US, increasing competition for potential employers despite economic and international uncertainty. According to the US Bureau of Labor Statistics (BLS) Job Openings and Labor Turnover Survey (JOLTS), there were approximately 7.2 million job openings in the United States as of early 2026.
The US staffing and recruitment industry alone generated approximately $180 billion+ in annual revenue for the past few years, according to Staffing Industry Analysts (SIA), demonstrating a growing demand for specialist support and making the US the largest staffing market globally. This comes from a demand for recruitment services that’s particularly strong in technology, healthcare, finance, and logistics, where higher turnover and specialized skill requirements are common.
Temporary and contract staffing is widely used in sectors with fluctuating demand, and in fact, according to the American Staffing Association (ASA), US staffing companies employ approximately 2.5 million temporary and contract workers each week.
Recent trends shaping the market include increased use of technology to speed up the recruitment process, as well as the growth of remote and hybrid work models and the expansion of international hiring. Companies are also increasingly using Employer of Record (EOR) and Professional Employer Organization (PEO) solutions to manage compliance and payroll when hiring across state or national borders.

Recruitment Process in the United States
The recruitment process in the United States typically involves several structured stages.
- Employers or recruitment agencies begin by defining role requirements and sourcing candidates through databases, job platforms, and professional networks.
- Candidates are then screened through interviews, skills assessments, and background checks.
- Shortlisted candidates proceed to client interviews, followed by offer negotiation and onboarding.
Importantly, the timeline varies depending on the type of recruitment. Temporary staffing can be completed within days or weeks, while executive search processes may take several months due to the level of specialization and seniority involved.
Recruitment agencies play a central role in managing these steps, particularly for companies seeking to reduce hiring timelines or access specialized talent pools.
How to Choose a Recruitment Agency in the United States
Choosing a recruitment agency in the US depends on hiring needs, industry focus, and organizational structure.
Companies with established US entities typically use domestic recruitment agencies such as Robert Half, Randstad, or Adecco for local hiring. These agencies are effective for sourcing candidates and managing placement processes.
For specialized hiring, such as executive roles or technical positions, firms like Korn Ferry or TEKsystems provide targeted expertise and access to niche talent pools.
Budget and time-to-hire considerations are also important. High-volume staffing agencies offer faster placement, while executive search firms require longer timelines but provide more targeted results.
For companies without a US legal entity, international providers such as INS Global offer Employer of Record solutions. This enables compliant hiring, payroll management, and HR administration without requiring entity setup.
Looking For Your Next Recruitment Partner in the US?
The United States recruitment market includes a wide range of agencies, from global staffing firms such as Robert Half and Randstad to specialized providers, including TEKsystems for technology hiring and Korn Ferry for executive search. Each agency serves a distinct function, depending on hiring volume, industry focus, and seniority of roles.
For companies operating internationally, however, recruitment alone may not be sufficient.
If you’re hiring in the US without a local entity already set up, providers such as INS Global and others offer Employer of Record (EOR) and Professional Employer Organization (PEO) solutions that enable compliant hiring in the United States without establishing a local entity.
For organizations expanding into the US market or managing cross-border teams, working with a provider that combines recruitment with compliance and employment support can simplify the process and reduce operational risk.
Other FAQs

These agencies cover different segments of the market, including professional staffing, executive search, technology recruitment, and high-volume hiring. For international companies, INS Global is often included as it enables compliant hiring in the US without requiring a local legal entity. The best agency ultimately depends on the type of role, industry, and hiring scope.
TEKsystems is widely recognized for technology recruitment in the United States, particularly for roles in software engineering, cybersecurity, cloud infrastructure, and IT support.
Companies with ongoing or project-based technical hiring need may use other agencies, such as Robert Half and Randstad, who also offer dedicated technology recruitment divisions. These firms are often preferred when companies require a mix of technical and non-technical roles or broader workforce solutions.
Recruitment agency fees in the United States vary depending on the type of service provided. For permanent placements, agencies can typically charge between 10-30% of the candidate’s annual base salary as a one-off payment.
The exact percentage depends on factors such as role seniority, industry, and hiring difficulty, and for temporary or contract staffing, agencies usually apply an hourly markup on the employee’s wage.
Note: Executive search firms such as Korn Ferry often charge higher fees, sometimes structured in stages, due to the complexity and seniority of the roles involved.
A recruitment agency is responsible for sourcing, screening, and placing candidates into roles within a company. Once the candidate is hired, the employment relationship is typically managed directly by the employer.
A Professional Employer Organization (PEO) or Employer of Record (EOR), on the other hand, manages employment responsibilities in the US, including payroll, tax compliance, employment contracts, and benefits administration.
Under an EOR model, the provider goes one step further and acts as the client company’s ongoing legal employer in a specific jurisdiction.
Function | Recruitment Agency | EOR |
Sources candidates | Yes | Sometimes |
Legal employer | No | Yes |
Payroll management | No | Yes |
Compliance management | No | Yes |
Entity required | Usually yes | No |
Yes, foreign companies can hire employees in the United States without establishing a local legal entity by using an Employer of Record. The EOR becomes the legal employer and is responsible for payroll processing, tax withholding, employment contracts, and compliance with federal and state labor laws.
This model allows companies to enter the US market more quickly and with reduced administrative burden. It is commonly used for market testing or remote team expansion before establishing a formal presence.
Temporary staffing placements in the United States can often be completed within days, while permanent recruitment generally takes several weeks. Executive search projects handled by firms such as Korn Ferry may take several months due to seniority and candidate targeting requirements.
The time required to hire through a recruitment agency in the United States depends on the type of role and the recruitment model used.
Many recruitment agencies in the United States specialize in specific industries or job functions. For example, TEKsystems focuses on technology roles, while Robert Half has dedicated divisions for finance, accounting, and legal recruitment.
Other firms, such as Randstad and ManpowerGroup, operate across multiple sectors and provide more generalist recruitment services.
Choosing an industry-specific agency is often beneficial when hiring for specialized or technical roles, as these agencies typically have deeper candidate networks and market knowledge.
Companies typically use recruitment agencies to reduce time-to-hire, access specialized talent, or fill roles at scale. Agencies are particularly useful when internal HR teams lack the resources or networks to efficiently source candidates.
However, internal hiring may be more appropriate for companies with established talent acquisition teams and ongoing recruitment needs. However, even large organizations often rely on agencies for niche roles or urgent hiring requirements.
In cases where companies are expanding internationally or hiring across borders, using an EOR provider such as INS Global may be more appropriate than traditional recruitment alone, as it combines hiring with compliance and ongoing employment management.
Recruitment agencies in the United States place candidates for a wide range of roles, depending on their specialization. High-volume staffing firms such as Adecco and ManpowerGroup often focus on operational roles, including warehouse staff, customer service representatives, and production workers.
Professional staffing firms such as Robert Half typically place finance professionals, legal staff, and administrative staff. Technology-focused agencies such as TEKsystems specialize in IT and software-related positions.
Executive search firms such as Korn Ferry focus on senior leadership and board-level roles.
Aerotek is often considered one of the largest recruitment and staffing agencies in the United States by revenue and workforce scale, particularly in industrial, engineering, and manufacturing staffing. Other major firms include Adecco, ManpowerGroup, and Randstad.
Large staffing firms typically operate nationally and provide a combination of temporary staffing, permanent recruitment, outsourcing, and workforce management solutions across multiple industries.
Recruitment agencies can be highly valuable for small businesses that lack dedicated internal recruitment teams or need to hire quickly. Agencies help reduce sourcing time, improve candidate quality, and provide access to broader talent networks.
For small businesses entering new markets or hiring internationally, agencies and EOR providers can also reduce legal and administrative burdens. Although agency fees add cost, many companies consider the time savings and reduced hiring risk worthwhile.
The best recruitment agencies for engineering hiring in the United States include Aerotek, Actalent, Randstad Engineering, and TEKsystems for engineering and technical roles linked to IT infrastructure and systems.
The ideal provider depends on the engineering discipline involved, such as mechanical, civil, software, electrical, aerospace, or industrial engineering. Specialized engineering recruiters often maintain stronger technical screening capabilities and industry-specific candidate networks.
