About The Position

Help design reliable mechanical systems for radar and multi-sensor products, taking them from concept development through detailed design, prototyping, testing, and production. MatrixSpace develops AI-enabled radar and sensing systems that help people understand what's happening in the world around them. By combining advanced radar, edge computing, and AI, we deliver situational awareness in environments where traditional sensing solutions struggle. We are seeking a Mechanical Engineer II to design and develop mechanical components and electro-mechanical assemblies for radar and multi-sensor hardware. You’ll work closely with mechanical, electrical, firmware, and systems engineers to develop concepts, create detailed designs, validate prototypes, and support the transition into production. This is a hands-on individual contributor role for an engineer with professional product-development experience who can take ownership of assigned design work, apply sound engineering judgment, and execute with guidance from senior engineers.

Requirements

• Bachelor’s degree in Mechanical Engineering or a related field, or equivalent practical experience/background.
• 4–6 years of relevant professional experience in mechanical design and hardware development.
• Experience using 3D CAD tools, with SolidWorks preferred, to create parts, assemblies, and mechanical drawings.
• Experience contributing to mechanical designs from concept development through prototype fabrication and testing.
• Working knowledge of mechanical tolerances, materials, fasteners, manufacturing processes, and assembly practices.
• Experience building, testing, and troubleshooting physical hardware in a product-development environment.
• Familiarity with designing components for machining, sheet metal fabrication, or other common manufacturing methods.
• Ability to document design decisions, communicate technical issues, and collaborate with engineers and manufacturing partners.
• Experience applying Geometric Dimensioning & Tolerancing (GD&T) and performing tolerance stackups. Per ASME Y14.5

Nice To Haves

• Experience supporting production builds or resolving manufacturing issues with suppliers or contract manufacturers.
• Experience with ruggedized electronics, radar, sensing systems, or other integrated electro-mechanical products.
• Experience with thermal, structural, shock, or vibration analysis and testing.
• Familiarity with 3D printing and other rapid-prototyping methods.
• Basic electro-mechanical assembly and troubleshooting skills, including wiring, soldering, and use of diagnostic tools.

Responsibilities

• Design and develop mechanical components and electro-mechanical assemblies using SolidWorks or similar CAD tools.
• Contribute throughout the product lifecycle, from concept development and detailed design through fabrication, integration, testing, and production.
• Create and maintain 3D models, assemblies, and manufacturing drawings for machined parts, sheet metal, and other mechanical components.
• Apply appropriate materials, tolerances, fasteners, and manufacturing methods to develop practical, reliable designs.
• Participate in design reviews and incorporate feedback on performance, manufacturability, assembly, and serviceability.
• Build and test prototypes, evaluate results, and refine designs to resolve mechanical and system-integration issues.
• Collaborate with suppliers and manufacturing partners to address fabrication and assembly questions and support the transition from prototype builds into production.
• Develop and maintain engineering documentation, including bills of materials, assembly procedures, build instructions, and design revisions.
• Support lab and field testing, customer demonstrations, and field deployments, including limited travel to our Hoffman Estates, Illinois site.
