WHAT TO LOOK FOR

What to look for in a principal engineer

These four areas show whether a candidate can lead your work, win more of it and develop your people.

Technical standing

Ask about the projects where the candidate was principal-in-charge or engineer of record: scale, complexity and what went wrong. Strong principals explain their judgment and how they protected quality and the firm.

Licensure in the right states

Most principals need a Professional Engineer (PE) license in the states where they seal work (see NCEES), and structural principals may need an SE license in some states. We verify licenses before shortlisting.

A real book of relationships

Look for principals who lead pursuits and win repeat work. Then check with references whether clients choose them personally, rather than just the firm they work for.

Ownership mindset

In many firms, principals are owners or future owners. Ask how they think about utilization, margin and growth, and whether their ambitions fit your ownership and succession plans.

WHY HIRES FAIL

Why principal engineer hires fail

Most failed principal hires trace back to one of three avoidable mistakes.

Buying a book that does not move

Clients and agency relationships do not always follow a principal to a new firm. Assess relationships and win history realistically instead of paying for a promised book of business.

A technical star who will not sell

Some outstanding engineers do not want business development responsibility. If the role needs it, test it with evidence before the offer.

Unclear path to ownership

When a principal joins expecting equity that never comes, or the terms are vague, they often leave. Agree what the title means, including any ownership path, before the search.

Principals are rarely looking, so we approach them directly and confidentially from day one. To understand how fees work and what affects them, see what engineering executive search costs.

OUR PROCESS

How our principal engineer executive search works

Because the search is retained, your appointment gets a dedicated team, clear milestones and a process built on evidence.

Define success

First, we agree what the leader must achieve. Then we build a behavioral blueprint with the McQuaig Job Survey.

Map the market

Next, we map principals, associate principals and senior project managers ready for the step up, by discipline, region, licensure and client base.

Approach confidentially

We approach candidates directly and discreetly rather than advertising the role.

Assess in depth

Every shortlisted candidate goes through RoleDNA™ Mapping, which covers eight levels, and is scored against your success profile.

Shortlist and close

Finally, you review two to four scored candidates. Then we manage references, offer and onboarding.

You can also see our executive search process step by step or read how we work with clients.

RoleDNA™ Mapping: evidence before the first interview

Every shortlisted principal goes through RoleDNA™ Mapping, which covers eight levels, so you can compare senior engineers fairly before you meet them:

1. Job Location Mapping
2. Executive Summary
3. Professional Photo
4. Candidate Introduction
5. Key Competency Responses
6. Behavioral Assessment
7. Verified References
8. Detailed Resume

For example, the Key Competency Responses ask each candidate to describe a pursuit they led and a project where they made a difficult technical call. In addition, the Behavioral Assessment uses the McQuaig Word Survey, matched to the role profile from the McQuaig Job Survey.

Results are then scored against the success profile for your role and shared in a 24/7 online client dashboard. Learn more about RoleDNA™ Mapping.

License and reference checks

We confirm each candidate’s PE license, and any SE license, the states it covers and its status before shortlisting. We also take references from firm leaders, clients and engineers who worked for them, so we can check technical quality, client relationships and how they developed staff.

A free replacement guarantee on every placement

Every placement comes with a 12-month free replacement guarantee as standard, extended to 2 years for senior roles. If the person leaves within the guarantee period, we find a replacement free of charge, subject to the agreed terms of engagement. How our guarantee works.

Our work does not stop at the signed offer, either. We support negotiation and the notice period, and we stay involved through onboarding and the first critical months.

Firms of every size

We work with consultancies of every size, from regional practices to multi-office firms. In a growing firm, one principal can open a new market or office, so we also run a dedicated executive search process for growing engineering firms.
