WE ARE LOOKING FOR THE BEST ABOUT US 42dot is a mobility AI company committed to solving mobility challenges with software and AI. As the Global Software Center of Hyundai Motor Group, 42dot pioneers the future of mobility by advancing the development of software-defined vehicles.  We develop safety-first, user-centric software-defined vehicle technologies that deliver the latest performance through continuous updates like smartphones. By advancing software and AI technology, 42dot envisions a world where everything is connected and moves autonomously through a self-managing urban transportation operating system. ABOUT THE ROLE At 42dot, we are building the high-performance hardware that powers the next generation of autonomous mobility. As the Principal Mechanical Engineer, you will be the technical lead for all mechanical aspects of our compute platforms. Your scope ranges from the precision engineering of ECU enclosures and advanced thermal solutions to the design of the physical infrastructure—fixtures and test benches—that enables our firmware and hardware validation. Beyond design, you are a process architect. You will own the mechanical product development lifecycle, define engineering workflows, and manage the PLM (Product Lifecycle Management) for all mechanical components, ensuring a seamless transition from prototype to volume manufacturing. Responsibilities - Lead Mechanical Design: Drive the design and development of ECU enclosures, fixtures, prototypes, and test benches, and their integration to manufacturing and test infrastructure - Thermal & Environmental: Own the thermal design strategy for high-compute electronics, ensuring reliability under extreme automotive environmental conditions. - Process & PLM: Define and manage the mechanical engineering workflow. Direct the implementation and maintenance of PLM systems to ensure robust version control and documentation for all mechanical assemblies. - Cross-Functional Orchestration: Interface with EE, Fi
