Job description

RADWIN is looking for a hands-on Senior Mechanical Engineer to drive the mechanical development of our next-generation products, from concept through mass production.

Reporting to the Platform Group Manager, you will take technical ownership of mechanical design across multiple projects. You will work closely with RF and antenna, digital and power, compliance, and manufacturing teams, as well as external suppliers and contract manufacturers.

Responsibilities

• Drive mechanical development from initial concepts and detailed design through validation, tooling approval, and production ramp-up.
• Design outdoor enclosures, radomes, antenna structures, heat sinks, mounting kits, and brackets for pole, wall, and tower installations.
• Perform thermal, structural, and dynamic analyses, including vibration, wind load, and drop, and validate simulation results against lab measurements.
• Define and execute mechanical qualification tests, including IP sealing, impact (IK), UV exposure, salt fog, vibration, shock, and temperature cycling. Investigate failures and implement corrective actions.
• Select materials and manufacturing processes suitable for outdoor environments, including glass-reinforced plastics, die-cast aluminum, and RF-transparent radome materials.
• Apply design for manufacturing and assembly (DFM/DFA), working directly with suppliers on injection molding, die-casting, machining, sheet metal, and gasketing.
• Collaborate with RF and antenna engineers on radome performance, antenna integration, and EMI shielding, and with PCB designers on board outlines, connectors, and thermal paths.
• Create and maintain mechanical documentation, including 3D models, GD&T drawings, tolerance analyses, BOMs, ECOs, and PLM releases.
• Support production and resolve mechanical issues identified in manufacturing or in the field.
• Contribute to design reviews, share technical expertise, and mentor less experienced engineers.

Requirements

• BSc in Mechanical Engineering.
• At least 8 years of mechanical design experience in electronics packaging, including at least 3 years designing outdoor equipment.
• Proven ability to independently own complex mechanical development projects from concept through production.
• Advanced proficiency in SolidWorks and hands-on experience with thermal and structural simulation tools, such as SolidWorks Simulation, Flow Simulation, ANSYS, or FloTHERM.
• Proven DFM/DFA experience with injection molding, die-casting, machining, and sheet metal, including direct collaboration with toolmakers and suppliers.
• Strong knowledge of GD&T, technical drawings, and tolerance analysis.
• Experience with environmental and safety standards, such as IEC 60529 (IP), IEC 62262 (IK), IEC 62368-1, and relevant ETSI/IEC environmental classifications.
• Experience with PLM systems, engineering change processes, and BOM management.
• Strong practical skills in prototype assembly, lab testing, and troubleshooting.
• Strong communication and collaboration skills.
• Excellent written and spoken English.

Advantages

• MSc in Mechanical Engineering.
• Experience designing telecom or RF equipment, particularly antenna structures, radomes, and EMI shielding.
• Experience with railway or transportation equipment and standards, including EN 50125 and EN 50155.
• Experience working with contract manufacturers in Asia.
• Experience mentoring engineers or providing technical leadership.
