Mechanical Engineer Salary in Engineering Services Consulting

The largest ME employer sector, often overlooked

The Bureau of Labor Statistics Occupational Employment and Wage Statistics tables for SOC 17-2141 within NAICS 541300 (Architectural, Engineering, and Related Services), May 2025 release, report 60,610 mechanical engineers employed at engineering consulting firms, with a sector median of $103,440 and a mean of $113,970. The mean sits well above the median here, which is the signature of a sector with a long senior tail: licensed PEs and principals pull the average up without moving the midpoint.

Engineering services consulting is the single largest employer of MEs in the US. On the same May 2025 OEWS release it employs more mechanical engineers than aerospace product and parts manufacturing (12,060), motor vehicle manufacturing (4,330) and scientific research and development services (21,390) added together. The sector is dominated by global multi-discipline firms (AECOM, Jacobs, Stantec, WSP) and large employee-owned firms (Burns and McDonnell, Black and Veatch, HDR), plus a long tail of regional and specialty consultancies. The work is project-based: 6-month feasibility studies, 18-month design-build engagements, multi-year program management for federal clients. Pay is structured around chargeability (the percentage of hours billed to clients) and project margin, not headcount-only models.

The major employers, and what shapes pay at each

No consultancy publishes a mechanical-engineer median, and no survey publishes one per firm, so this table does not carry one. What it carries is the thing that actually decides your offer: what the firm builds, and how it structures compensation. At the employee-owned firms the ESOP contribution sits outside base pay entirely, so comparing two offers on base alone will mislead you.

AECOM

Global top-five engineering and construction. Broad multi-discipline project base, so MEs move between building systems and heavy civil programmes.

Jacobs Engineering

The most federal-weighted of the majors. Clearance-eligible work is a distinct pay track.

Stantec

Canada-headquartered with a large US presence. The buildings practice is where most MEs sit.

WSP USA

Strong NYC and Bay Area MEP practices. Multi-discipline integration on large commercial towers.

Burns and McDonnell

Employee-owned (ESOP). The annual ESOP contribution is a material part of total compensation on top of base.

Black and Veatch

Employee-owned. Utility-programme work on long engagements.

HDR Inc

Employee-owned. Healthcare facility design is a strong and durable niche for MEs.

ARUP

UK-headquartered. High-end commercial buildings, where MEP design content per project is unusually high.

The PE-license career curve

Engineering services consulting is the sector where PE licensure pays the largest absolute premium. The license is the gatekeeper for sign-off authority, which is the billable product the firm sells to clients. The curve below is this site's model of a career through licensure at a large consultancy, built by spreading the BLS OEWS May 2025 sector median and mean across the stages: it is not a published salary schedule, and no firm publishes one. Use it for the shape of the progression, and the sector figures above for the anchor.

The jump from EIT (Engineer in Training) to newly licensed PE is the single largest discrete pay event in a consulting ME career, typically $15,000 to $22,000 in the year of licensure. After that, base grows roughly $5,000 to $8,000 per year through senior levels, with bonus and ESOP contributions adding meaningful variance. The path to principal or partner is roughly 15 to 18 years from BS, with business-development capacity (rainmaker reputation) as the main qualifying criterion above the technical bar.
