Mechanical Engineer Jobs in Philadelphia: Frequently Asked Questions
How do I get a mechanical engineer job in Philadelphia?
Focus your search on Philadelphia's defense contractors at the Navy Yard, life sciences manufacturers in University City, and industrial firms in Northeast Philadelphia and the surrounding Delaware Valley. Candidates with experience in systems integration, thermal management, or GD&T modeling stand out in this market. Networking through local chapters of ASME and connections at Drexel or Penn Engineering also opens doors that online applications alone do not.
Which companies hire mechanical engineers in Philadelphia?
Companies currently hiring mechanical engineers in Philadelphia include Jacobs, dbHMS, and HDR, per current listings on Migrate Mate as of November 2026. Philadelphia's employer mix leans heavily toward defense primes, pharmaceutical equipment manufacturers, and mid-size industrial and energy firms clustered in the Navy Yard and the broader Delaware Valley region.
Are there remote mechanical engineer jobs in Philadelphia?
Yes, though with limits, since mechanical engineering work is often hands-on and tied to physical equipment, labs, or manufacturing floors. About 80% of mechanical engineer openings tied to Philadelphia are remote or hybrid as of November 2026, and those tend to be design, simulation, or project management roles rather than test, manufacturing, or facilities positions.
How can I get a mechanical engineer job in Philadelphia with little or no experience?
The most realistic entry path in Philadelphia is through co-op or internship programs at life sciences manufacturers and defense contractors, many of which recruit directly from Drexel, Temple, and Penn Engineering. Entry-level roles in quality assurance, facilities maintenance engineering, or CAD drafting at mid-size industrial firms in Northeast Philadelphia and the Delaware Valley often require only a degree and willingness to learn on-site systems and equipment.
