Mechanical Design Engineer Jobs in Missouri: Frequently Asked Questions
How do you become a mechanical design engineer in Missouri?
Start with a bachelor's degree in mechanical engineering from an ABET-accredited program, which is the baseline requirement for nearly every Missouri employer. Missouri does not require a state license to work as a mechanical design engineer in most private-sector roles, but engineers who sign and seal drawings or work on public projects must hold a Professional Engineer license issued by the Missouri Board for Architects, Professional Engineers, Professional Land Surveyors and Professional Geologists, obtained by passing the Fundamentals of Engineering and Principles and Practice of Engineering exams.
How much do mechanical design engineers make in Missouri?
Mechanical design engineers in Missouri earn a median of about $99,330 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $64,750 for the lowest 10% to over $142,100 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire mechanical design engineers in Missouri?
Companies currently hiring mechanical design engineers in Missouri include Boeing, The Waldinger, and MiTek, per current listings on Migrate Mate as of August 2026. Missouri's aerospace and defense sector, anchored in St. Louis, and its broad industrial manufacturing base in Kansas City generate especially steady demand for mechanical design talent.
Which Missouri cities have the most mechanical design engineer jobs?
Berkeley, Hazelwood, and St. Louis are the Missouri cities with the most mechanical design engineer openings. St. Louis leads because of its large aerospace and defense contractors and diversified manufacturing base, while Kansas City's strength in industrial equipment, agriculture machinery, and engineering services firms drives demand there, and Springfield's growing manufacturing sector accounts for openings outside the two major metros.
Are there remote mechanical design engineer jobs in Missouri?
Yes, but they're rare. Mechanical design engineering is a hands-on discipline that typically requires access to physical prototypes, lab equipment, and manufacturing floors, which limits full remote work. About 33% of mechanical design engineer openings tied to Missouri are remote or hybrid as of August 2026, and those roles tend to concentrate the remote portion on CAD modeling, documentation, and design review rather than testing or fabrication work.
How can I get hired as a mechanical design engineer in Missouri with little or no experience?
The most realistic entry path is an internship or co-op through an ABET-accredited Missouri engineering program, since Boeing, Emerson Electric, and many St. Louis and Kansas City manufacturers recruit directly from University of Missouri, Missouri S&T, and Washington University pipelines. New graduates can also target junior design or design support roles, as well as lateral entry from drafting or manufacturing engineering technician positions. Building a CAD portfolio in SolidWorks or CATIA and passing the Fundamentals of Engineering exam strengthens any early-career application considerably.
Where can I find and apply to mechanical design engineer jobs in Missouri?
You can find and apply to mechanical design engineer jobs in Missouri on Migrate Mate, which lists current Missouri openings updated regularly. Find roles that fit your experience and location, then apply directly to the employer through the listing.
