Diamond Antenna and Microwave • Brockton, MA

4d • $90,000

About The Position

The Mechanical Engineer III is a fully proficient engineer responsible for designing, analyzing, and supporting mechanical components and systems used in Diamond’s RF and electromechanical products. This role independently executes engineering tasks, leads moderate-complexity design efforts, collaborates cross-functionally, and ensures that designs meet performance, reliability, and manufacturability requirements.

Requirements

• Experience supporting high-reliability RF, microwave, and electromechanical product design.
• Ability to design components related to RF rotary joints, slip rings, FORJs, and precision rotating assemblies.
• Proficiency with tolerance analysis, GD&T, and precision machining considerations.
• Familiarity with ISO 9001/AS9100 engineering processes, configuration control, and ECO discipline.
• Understanding of ITAR/CUI requirements and working within controlled engineering environments.
• Experience working cross-functionally with machining, manufacturing, quality, and supply chain.
• Ability to support prototype builds, test evaluations, and root-cause investigations.
• Comfort generating detailed documentation, BOM structures, and manufacturing-ready drawings.
• Strong ability to balance design performance, manufacturability, and cost for Diamond product lines.
• Commitment to continuous improvement and standardization of engineering practices.
• Bachelor’s degree in Mechanical Engineering or related field.
• 4–7 years of engineering experience in product development or manufacturing.
• Strong proficiency with CAD (SolidWorks preferred), GD&T, and mechanical design fundamentals.
• Experience with precision assemblies, machined components, and complex electromechanical systems.
• Ability to interpret specifications, requirements, and quality standards.
• Strong analytical, communication, and collaboration skills.

Responsibilities

• Develop 3D CAD models, detailed drawings, and engineering documentation.
• Perform tolerance stack-ups, GD&T, analysis, and modeling of rotating/mechanical interfaces.
• Support NPI activities, prototype builds, and qualification testing.
• Collaborate with manufacturing to ensure designs meet production capability and cost objectives.
• Conduct root-cause analysis and corrective actions for product or build issues.
• Participate in customer or program technical reviews as required.
• Support configuration control, ECO processing, and revision discipline.
• Mentor junior engineers and contribute to engineering process improvements.
