Decision guides
Straight comparisons of engineering hiring models and disciplines
Each page defines both options precisely, compares them on the criteria engineering leaders actually weigh, and states which one we would recommend - including when the answer earns us less.

Choose the decision you are making
Model decisions sit at the top; discipline definitions sit below, for the requisitions that are really two different roles.

Contract Staffing vs. Direct Hire
Contract staffing adds engineering capacity for a defined term without adding permanent headcount. Direct hire builds your own team for work that isn't going away. The right call depends on whether the need is a project or a position.

Project Staffing vs. Permanent Hiring
Project staffing assembles a full team, sometimes several engineers across disciplines, for the duration of a defined initiative. Permanent hiring builds standing engineering capacity. The decision usually comes down to whether the work repeats.

RPO vs. Managed Staffing
RPO takes over your recruiting function for direct hires, using your process and employer brand. Managed staffing runs and governs a contingent workforce program, often across multiple vendors. Companies with high-volume direct hiring need RPO; companies with a large or fragmented contract workforce need managed staffing.

Engineering Recruiters vs. General Staffing Agencies
General staffing agencies recruit across industries and job families with broad reach and speed. Specialist engineering recruiters focus on technical disciplines, screening for depth a generalist process typically can't evaluate. The stakes of the role usually decide which one you need.

Commissioning Engineer vs. Project Engineer
A commissioning engineer verifies that installed systems function as designed, working through defined test levels up to integrated startup. A project engineer coordinates design, schedule, and cross-discipline execution across the life of the project. On a capital project, you typically need both, not one instead of the other.

Controls Engineer vs. PLC Engineer
A PLC engineer focuses on programming the logic that runs a controller: ladder logic, structured text, function block diagrams. A controls engineer owns the broader system architecture, instrumentation, HMI/SCADA integration, and network topology that the PLC sits inside. One is a specialist skill; the other is a systems role that often includes it.
