10 Best Engineering Staffing Agencies for 2026 (Ranked)

Key takeaway: The 10 best engineering staffing agencies for 2026 are: Actalent, Kelly Engineering, Belcan, Akkodis, Yoh, System One, Randstad Engineering, Experis, PEAK Technical Staffing, and Brunel. Actalent, Belcan, and Akkodis lead for large engineering programs and outsourced project teams; Kelly, Randstad, and Experis bring global staffing scale; Yoh, System One, PEAK, and Brunel are strong mid-size specialists for contract engineers and designers.

Engineering staffing agencies place mechanical, electrical, civil, industrial, aerospace, controls, and quality engineers, plus designers and drafters, on contract, contract-to-hire, and project-based assignments. Unlike retained engineering search firms that recruit permanent leaders, these agencies employ the engineer, bill the client hourly, and can supply whole project teams or embedded engineering services.

Demand is steady and the pipeline is thin. The Bureau of Labor Statistics projects about 195,000 openings a year in architecture and engineering occupations from 2023 to 2033, and the Deloitte and Manufacturing Institute 2024 study estimated that US manufacturers will need 3.8 million new workers by 2033, with as many as 1.9 million roles going unfilled if the skills gap persists. Semiconductor fabs, EV and battery plants, defense programs, and grid modernization all compete for the same engineers, which has pushed contract rates and time to fill up.

This list ranks agencies by engineering specialization, contract and project capability, geographic reach, and pricing clarity. For permanent engineering leadership and retained search, see our engineering and manufacturing recruiting firms list; for software roles, see IT staffing agencies.

How to choose an engineering staffing agency

Decide first whether you need individual contractors, a managed project team, or outsourced engineering deliverables. Actalent, Belcan, Akkodis, and System One can run entire workstreams under a statement of work; Kelly, Randstad, Experis, Yoh, PEAK, and Brunel are strongest at placing individual engineers and designers. For defense and aerospace programs, confirm the agency's experience with ITAR, export control, and clearance-eligible candidates before signing.

Compare bill rates against total program cost. Contract engineer markups typically run 40 to 70 percent over the engineer's hourly rate depending on discipline and benefits, and contract-to-hire conversion fees fall after six to twelve months. Ask for recruiter tenure and discipline specialization, because the difference between a recruiter who can read a drawing and one who keyword-matches résumés shows up in submittal quality within the first week.

FAQ

What does an engineering staffing agency do? An engineering staffing agency recruits and employs engineers, designers, and technicians and assigns them to clients on contract, contract-to-hire, or project basis, billing an hourly rate that covers pay, benefits, taxes, and margin. Many also offer direct hire placement and outsourced engineering services.

How much do engineering staffing agencies charge? Contract engineer markups typically run 40 to 70 percent over the engineer's hourly pay rate, so a $60 per hour mechanical engineer might bill at $85 to $100 per hour. Direct hire fees usually run 20 to 25 percent of first-year salary.

What is the largest engineering staffing agency? Actalent, the engineering and sciences business separated from Aerotek by Allegis Group in 2021, is generally considered the largest engineering staffing and services firm in North America, followed by Belcan, Akkodis, and Kelly Engineering.

What is the difference between an engineering staffing agency and an engineering recruiting firm? Staffing agencies employ engineers and place them on contract or contract-to-hire assignments, billing hourly. Recruiting or search firms place permanent employees for a one-time fee and typically focus on senior and leadership roles. Many agencies on this list do both.

How long does it take to fill a contract engineering role? Common disciplines such as mechanical or electrical design engineers typically fill in one to three weeks. Specialized roles such as controls engineers, stress analysts, or cleared aerospace engineers can take four to eight weeks.
