A Chicago engineering staffing agency sources, screens, and places qualified engineering professionals for local employers. Frontline Source Group provides contract staffing for project-based engineering roles, contract-to-hire engagements, and direct hire placement across manufacturing, civil, industrial, mechanical, electrical, and design engineering, working from a network of qualified engineers with verified credentials and technical skills.

Frontline places Mechanical Engineer, Electrical Engineer, Civil Engineer, Industrial Engineer, Manufacturing Engineer, Design Engineer, Chemical Engineer, Environmental Engineer, Safety Engineer, Operations Engineer, Computer Engineer, Project Engineer, CAD Designer, and CAD Drafter roles.

Chicago's economy sustains engineering demand across manufacturing, industrial operations, construction and civil infrastructure, energy, and technology. The manufacturing and distribution operations along the I-55 and I-290 corridors drive demand for manufacturing, mechanical, and industrial engineers, while civil and structural demand is driven by ongoing infrastructure and construction activity. Design roles, including CAD, support architecture, engineering, and construction firms across the metro.

Frontline Source Group's Chicago office is at 321 N Clark Street, Chicago, IL 60654, in the River North business district. The office serves the Loop, River North, Fulton Market, the West Loop, and surrounding suburbs such as Schaumburg, Naperville, Oak Brook, and Rosemont. Hours are Monday through Thursday 8:00am to 6:00pm and Friday 8:00am to 5:00pm Central, with interviews by scheduled appointment.

Chicago engineering employers choose Frontline for the 5-Year Placement Warranty, 20 times longer than the 90-day industry standard guarantee; a 98.94%% placement retention rate across 5,619+ placements versus an industry average near 70%; and openly published pricing backed by Forbes recognition for 9 consecutive years and ClearlyRated Best of Staffing honors.

A 90-day guarantee leaves the employer absorbing the full cost of a new search if a hire fails after day 91. Frontline's 5-Year Placement Warranty on direct hire placements extends that protection 20 times longer. For an engineering hire, where a mis-hire can delay a project or disrupt a production line, that extended protection is a material reduction in risk.

Every Frontline Chicago engineering candidate completes a structured pre-placement process before being presented to a client, including a recruiter interview, credential verification, and skills and technical assessments. This screening supports a reliable network of qualified engineers across manufacturing, civil, industrial, mechanical, electrical, and design disciplines, and it is why Frontline stands behind every direct hire with the 5-Year Placement Warranty.

Contract engineering staffing is billed at a single transparent hourly rate that covers the candidate wage, payroll taxes, benefits, insurance, and Frontline's service fee.
