Senior Mechanical Designer

JLRD, Inc. is a Florida-based MEP (mechanical, electrical, plumbing) and fire protection consulting engineering firm founded in 1991. Headquartered in West Palm Beach with offices in Merritt Island, Jacksonville, and Tampa, JLRD delivers all four engineering disciplines in-house across healthcare, education, government, federal, aviation, utilities and infrastructure, commercial and mixed-use, hospitality, residential, and mission-critical facilities.

We are privately owned and engineering-led. We compete on technical depth, not scale, and we build teams accordingly.

The Senior Mechanical Designer is a senior producer on JLRD's firm-wide Mechanical discipline. This role owns entire mechanical design scopes end-to-end, coordinates across disciplines proactively, mentors junior team members, and supports QA/QC on team output.

You will work across projects and clients regardless of which office originates them, collaborating with Designers, Engineers, and Project Managers across all JLRD offices. This position reports to our Mechanical, Plumbing, and Fire Protection Department Lead.

Position is based in Merritt Island, Florida or West Palm Beach, Florida. On-site.
