We are seeking a highly motivated Senior Mechanical Engineer to lead the design and development of mechanical solutions for advanced mmWave semiconductor systems and RF hardware platforms. This role focuses on mechanical design, product integration, packaging, and manufacturability, with supporting responsibilities in thermal management for high-performance electronic systems. The ideal candidate will have strong experience in mechanical design for electronic hardware, along with working knowledge of thermal design principles to ensure system reliability and performance. Responsibilities Design and develop mechanical enclosures, housings, brackets, and structural components for RF and high-speed electronic systems. Lead mechanical design for evaluation boards, system platforms, and production hardware. Drive mechanical integration of RF modules, connectors, antennas, and high-frequency components. Ensure designs meet requirements for structural integrity, manufacturability, and assembly efficiency. Collaborate with hardware, RF, and system engineers to optimize component placement, packaging, and system layout. Develop and implement thermal management solutions, including heat sinks, airflow strategies, and material selection. Perform or support basic thermal analysis and validation to ensure adequate cooling and reliability. Create detailed 3D models, mechanical drawings, and product documentation. Support prototype builds, testing, and design iteration through product development cycles. Interface with manufacturing partners and vendors to support fabrication, assembly, and production ramp. Conduct design reviews and enforce best practices in mechanical and product design. Requirements BS or higher in Mechanical Engineering or related field. 5+ years of experience in mechanical design for electronic or embedded systems. Strong proficiency in 3D CAD tools such as SolidWorks, Creo, or similar. Experience designing enclosures and mechanical structures for electronic hardware. Familiarity with manufacturing processes such as CNC machining, sheet metal, die casting, and injection molding. Experience with tolerance analysis, GD&T, and design for manufacturability (DFM/DFA). Strong understanding of materials selection and mechanical reliability. Hands-on experience supporting prototype builds and production transitions. Working knowledge of thermal management techniques for electronic systems. Familiarity with basic thermal analysis tools or methods (e.g., simulation or empirical testing). Excellent problem-solving, collaboration, and communication skills. Ability to manage multiple tasks in a fast-paced engineering environment. Preferred Skills Experience with RF/mmWave hardware packaging and integration. Familiarity with PCB-related mechanical constraints (stack-ups, connectors, shielding). Experience designing heat sinks, thermal interfaces, and airflow solutions. Exposure to thermal simulation tools (ANSYS, Icepak, FloTHERM, or similar). Experience designing test fixtures and mechanical support structures. Familiarity with environmental and reliability testing (vibration, shock, temperature). Experience working with contract manufacturers and suppliers. Compensation Competitive salary, great benefits and equity in a growing company
