Engineering Recruiting Comparison
Trueline engineering recruiting recruits permanent engineering professionals and leaders at mid-market firms across construction, manufacturing, and industrial sectors. If you need a permanent VP of Engineering who understands your industry, Trueline is the better choice. Kelly Engineering Resources places contract engineers on temporary assignments at Fortune 500 companies. If you need contract engineers on 6-month projects, Kelly can deliver.
Trueline by the Numbers
Why People Compare Kelly Services and Trueline
This comparison matters because the word "engineering recruiting" covers two very different services. One is filling contract seats with technical skills. The other is finding leaders who build engineering teams and drive long-term strategy. Knowing which one you need determines which firm fits.
Kelly Services has been in staffing for 80 years. That brand recognition puts them on a lot of shortlists by default. Trueline enters the conversation when companies want something more specific.
This comparison typically comes from one of these situations:
- An engineering-heavy company knows Kelly's name and wants to explore whether a more specialized firm would produce better candidates for permanent roles.
- A VP of Engineering used Kelly for contract staff augmentation and now needs a permanent Director of Engineering hire.
- A mid-market company finds Kelly's enterprise-oriented model too large and impersonal for their leadership search.
- A hiring manager in construction or manufacturing engineering wants a recruiter who understands their specific industry context.
Why Teams Choose Trueline
Trueline supports direct hire, temp staffing, and contract-to-hire across eight core industries.
Trueline is the right fit when the engineering hire is permanent, senior, and requires industry-specific knowledge.
- You need a permanent VP of Engineering, Director of Engineering, or Senior Project Engineer.
- The role requires understanding your specific industry: civil engineering for construction, manufacturing engineering for plant operations, or MEP engineering for building systems.
- You want access to engineering leaders who are employed and not actively looking.
- You need a dedicated account manager leading the search, not a transactional staffing handoff.
- You want one partner who understands the full engineering org chart, from individual contributors through executive leadership.
- Culture fit and retention matter. Trueline's 96% past-one-year retention rate reflects a focus on long-term placement. 60-day replacement guarantee.
Trueline's construction and engineering recruiting practice built relationships with engineering leaders across construction, manufacturing, and industrial sectors through its Terrafirma magazine heritage. Those editorial connections now power a recruiting network that reaches passive candidates, the professionals who are running projects and leading teams and would never show up in a staffing database.
When Kelly Services Might Be Enough
Kelly Engineering Resources has their lane in specific areas of the market.
- You need contract or temporary engineers for 3-12 month project assignments.
- You are a Fortune 500 company with an MSP or VMS program that Kelly can plug into.
- You need engineers on staff augmentation at an hourly bill rate, not permanent hires.
- Science or clinical staffing is part of the need alongside engineering.
- You want an enterprise vendor with global reach across 40 countries.
For anything beyond contract engineering fill, Trueline is the stronger path.

The Trueline Advantage
The 6-Step Trueline Talent Process
Trueline starts with market research and a focused intake, then moves immediately into outbound outreach across its network. Every candidate is evaluated for industry knowledge, culture fit, and long-term potential. After placement, Trueline creates a tailored evergreen article about your company.
1. Permanent Engineering Leadership Placement
Kelly's core business is temporary staffing. Their engineering division places contract engineers on project assignments. Trueline focuses on permanent engineering professionals and leaders: VPs, Directors, Senior Engineers who join your team and build strategy for years. These are fundamentally different searches that require different sourcing approaches and candidate evaluation.
2. Industry-Specific Engineering Evaluation
A civil engineer for a construction firm has different needs than a civil engineer for an environmental consultancy. A manufacturing engineer at an automotive plant operates in a different world than one at a food processing facility. Trueline's recruiters, informed by Terrafirma magazine and years of industry presence, evaluate engineering candidates on industry context and business fit, not just technical credentials.
3. Off-Market Access to Engineering Leaders
The best engineering leaders are managing projects, leading teams, and solving problems. They are not browsing temp staffing databases or responding to mass recruiter outreach. Trueline's publication network creates a warm, trusted path into conversations with these professionals. Kelly's staffing database reaches engineers who are available and looking, which is a materially different candidate pool.
4. Full Engineering Org Chart Coverage
An engineering-heavy company does not just need project engineers. It needs engineering managers, Directors of Engineering, and VPs of Engineering. Trueline covers the full engineering org chart from individual contributors through executive leadership, with the industrial context that makes each level of hire work. Kelly's engineering division places contract individual contributors, not engineering leaders.

Where Kelly Services Fits
1. Contract Engineering Staff Augmentation
If you need 10 engineers on 6-month contracts to support a major project, Kelly Engineering Resources is built for that. They have the infrastructure, payroll systems, and candidate pipeline to place contract engineers at scale. Trueline does not operate in the contract staffing model.
2. Enterprise Scale and Global Reach
Kelly operates in 40 countries with thousands of internal staff. For a multinational company needing engineering staffing across regions, Kelly's global infrastructure is a a lane. Trueline's reach is US-focused and relationship-driven.
3. Science and Clinical Staffing
Kelly has dedicated science and clinical divisions that Trueline does not serve. If your organization needs lab technicians, clinical researchers, or scientific staff alongside engineers, Kelly can cover both from one vendor.
What Makes Trueline Different In This Matchup
The core difference is what each firm was built to do. Kelly was built to staff temporary workers at large companies. Trueline was built to place permanent leaders at mid-market industrial firms.
That structural difference shows up everywhere. Kelly's engineering candidates are typically available for their next contract assignment. Trueline's engineering candidates are typically employed, performing well, and reachable only through trusted industry relationships. Kelly evaluates on technical skills and availability. Trueline evaluates on technical skills, industry context, leadership capability, and cultural fit.
Trueline's engineering recruiting heritage through Terrafirma magazine is the sourcing advantage that makes this possible. Years of engineering-focused industry publishing created relationships with thousands of engineering leaders. Those relationships now fuel a recruiting network that surfaces candidates who would never respond to a staffing inquiry. For the VP of Engineering or Director of Engineering search, that access is the difference between a strong shortlist and a mediocre one.
The Roles and Situations Where the Difference Is Clearest
- Use Kelly for contract engineers on 3-12 month project assignments.
- Use Trueline for permanent VP of Engineering, Director of Engineering, and Senior Engineer hires.
- Use Kelly for enterprise-scale staff augmentation programs.
- Use Trueline when industry-specific engineering knowledge matters (construction, manufacturing, industrial).
- Use Kelly for science or clinical staffing alongside engineering.
- Use Trueline when you need engineering talent at every level, from project engineers through VPs, through one partner.
- Use Trueline for confidential engineering leadership replacements.
