Gulfstream Strategic Placements connects candidates with commercial mechanical contractors nationwide. Explore HVAC, plumbing, piping, sheet metal, building automation and VDC/BIM roles, from field service to project leadership.
Open positions, commercial mechanical contractors
Commercial HVAC, plumbing, piping and controls openings. Every listing shows its posted work location; direct-hire recruiting is separate from union dispatch.
Gulfstream Strategic Placements has recruited for commercial mechanical, electrical and plumbing contractors since 2014 from our office in Corona, California. These are the working habits candidates can expect.
A conversation before any submission
Your recruiter talks with you about your experience, goals and availability before your background is shared with an employer. Nothing is submitted without that discussion.
Confidential by default
Client names stay private on public listings. Your recruiter shares employer details once there is a real fit to discuss, and your search stays between you and us.
Union and merit shop
We fill union-covered and salaried roles for union and merit shop contractors. Gulfstream is independent of any union, and hall dispatch rules stay with the hall.
Trade people, trade language
We recruit service techs, chiller and controls techs, BIM/VDC designers, estimators and project managers, so conversations start with equipment, scope and schedule, not buzzwords.
For employers, our candidate-slate window is 14 business days. This is not a promised interview date, offer date or start date for an applicant.
Apply and review
Apply to a listed opening or share your experience and preferred work location. Your recruiter reviews your background against the role requirements.
Discuss the fit
Your recruiter confirms your experience, availability and goals, and discusses the opportunity before a submission.
Interview and next steps
Interviews, employer decisions and start dates depend on the role, fit and availability. Your recruiter explains the next step for the opportunity you discuss.
Our staffed office is in Corona. We support commercial mechanical contractor searches in the Inland Empire, Orange County, Los Angeles and San Diego, as well as nationwide. Coverage does not imply another office, an available candidate or a current opening.
Illustrative connections, not guaranteed moves or current openings. Qualifications and responsibilities differ by employer. This guide covers the wider industry; Gulfstream recruits for commercial mechanical contractors, not every setting shown.
