Summary
We’re an industrial product technology company based in Washington State seeking an experienced mechanical engineer (or engineer working with/directing a machine shop) to design and prototype sensor-integrated polymeric components used in fluid-handling equipment. This is a hands-on mechanical design and fabrication project — not a simulation-only or theoretical engineering role. You’ll be responsible for figuring out how to physically mount, embed, or integrate small sensors into polymeric/composite parts, designing the necessary machining and assembly processes, and delivering working prototype units.
Design must address all four of the following:
Mechanics — structural retention, mounting method, mechanical robustness under operating stress
Placement — sensor positioning/orientation strategy within or on the component, considering accessibility and function
Wiring — signal/power routing and strain relief from sensor to exit point, connector selection and integration
Waterproofing — sealing strategy to fully protect sensor and wiring from fluid ingress under operating conditions
Scope of Work:
Review sensor specifications (size, connector type, environmental requirements) and the host polymeric component geometry provided by us
Design mounting/placement strategy for embedding or affixing sensors within or onto the polymeric component, addressing mechanics, placement, wiring, and waterproofing as above
Produce CAD models and machining drawings for any required modifications to the host component (bores, pockets, channels, fittings, etc.)
Either perform machining/fabrication yourself or specify and oversee machining at a third-party shop
Build and deliver prototype units (estimated 2–6 units total across design iterations)
Validate fit, seal integrity, and mechanical robustness of prototypes (pressure/leak testing support welcome but not required unless you have in-house capability)
Document design decisions, drawings, and as-built configurations for internal engineering records
Iterate based on test feedback from our engineering team
Deliverables:
Mounting/placement design concept(s) with rationale (1–2 options minimum), addressing mechanics, placement, wiring, and waterproofing
CAD files and machining drawings (native + STEP/PDF)
Machining process plan or shop instructions, if outsourcing fabrication
Physical prototype units (2–6 total, per above)
Build documentation / as-built notes
Brief final report summarizing design, lessons learned, and recommendations for production scale-up
Ideal Candidate:
Mechanical engineering background with hands-on machining/prototyping experience (not purely CAD/desk work)
Experience working with polymers, composites, or plastic machining (preferred)
Experience integrating electronics/sensors into mechanical housings, including wiring routing and waterproofing/sealing design
Comfortable working from spec sheets and component drawings we provide, under an NDA
Able to either machine parts directly or manage a machine shop relationship
Must be based in the United States or Canada
NDA Required: This project involves proprietary component designs. You’ll be asked to sign an NDA before receiving detailed specifications.
Project Structure & Budget:
This is proposed as Time & Materials with a not-to-exceed cap. In your proposal, please include:
Your hourly rate:
An estimated total hours/cost to complete the scope above (this will become the cap)
Any separate estimate for machining/material costs if you’ll be subcontracting fabrication
Your relevant experience with polymer machining and/or sensor integration (mechanics, wiring, waterproofing)
Availability and estimated timeline to first prototype
Duration: Project-based, estimated several weeks depending on iteration needs.
Work Location: In person

Mechanical Design Engineer Jobs in Washington: Frequently Asked Questions
How do you become a mechanical design engineer in Washington?
Most mechanical design engineer roles in Washington require a bachelor's degree in mechanical engineering or a related engineering field. Washington does not require a state-issued license for most industry engineering positions, though engineers who stamp public-facing documents must be licensed through the Washington State Board of Registration for Professional Engineers and Land Surveyors. Many Washington employers, particularly in aerospace and defense, expect proficiency in CAD tools and familiarity with industry standards before hiring.
How much do mechanical design engineers make in Washington?
Mechanical design engineers in Washington earn a median of about $110,430 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $79,400 for the lowest 10% to over $167,680 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire mechanical design engineers in Washington?
Employers hiring mechanical design engineers in Washington right now include Blue Origin, Amazon, and Meta, based on current listings on Migrate Mate as of November 2026. Washington's aerospace and defense sector, anchored in the greater Seattle and Everett area, consistently produces some of the highest mechanical design engineer hiring volume of any state.
Which Washington cities have the most mechanical design engineer jobs?
Seattle, Redmond, and Kirkland have the most mechanical design engineer openings in Washington. Seattle and Everett lead due to the concentration of aerospace and advanced manufacturing employers along the Puget Sound, while Redmond and Bellevue draw significant hiring from defense electronics and technology-adjacent engineering firms with mechanical hardware development needs.
Are there remote mechanical design engineer jobs in Washington?
Yes, but they're rare. Mechanical design engineering is a hands-on discipline that typically requires access to labs, prototypes, and manufacturing floors, so most roles are on-site or hybrid at best. About 71% of mechanical design engineer openings tied to Washington are remote or hybrid as of November 2026. The portions of the role most amenable to remote work include CAD modeling, design reviews, and documentation tasks that don't require physical presence.
How can I get hired as a mechanical design engineer in Washington with little or no experience?
The most realistic entry path is an internship or co-op while completing an engineering degree, as Boeing, Blue Origin, and Paccar all run structured programs that regularly convert participants to full-time roles. New graduates can also target associate mechanical engineer or design technician postings, which serve as direct stepping stones into full design roles. Building a portfolio of CAD projects and pursuing the Engineer-in-Training designation through the Washington State Board of Registration strengthens applications considerably for candidates without commercial experience.
Where can I find and apply to mechanical design engineer jobs in Washington?
