About the role

Cyngn is seeking a S taff Mechanical Engineer who can own the mechanical design, integration, and release of major vehicle systems - while mentoring others and setting the technical bar for mechanical engineering at the company.
This is a high-impact, technically demanding position where you will drive the development of core mechanical systems from concept through mass production.
You will be responsible for specifications, CAD design, analysis, prototyping, testing, and release, while coordinating across teams and with external partners to deliver high-quality systems.

Own the mechanical technical specification, design, integration, and release for vehicle systems.
Create CAD models, detailed drawings, and specifications for parts and assemblies (SolidWorks).
Drive multiple product development cycles from concept to production, ensuring manufacturability and reliability.
Troubleshoot issues, identify root causes, and design corrective/preventative solutions.
Build, assemble, and run test fixtures for mechanisms - including necessary coding & electrical setups.
Characterize sensing systems (encoders, sensors) for bandwidth, latency, and other system parameters to support closed-loop motor control.
Develop and execute test plans, analyze results, and drive design improvements based on data.
Work closely with electrical, software, and external engineering partners to meet system-level goals for safety, performance, and cost.
Serve as design release engineer for systems such as hydraulics, sensors, and actuator assemblies.
Own Bills of Materials (BOM), assembly structures, and documentation within PLM systems (Arena).

8-12+ years of experience in mechanical engineering, ideally in robotics, automotive, or other complex electromechanical systems
Proven record of taking multiple products from concept through mass production.
Strong proficiency with SolidWorks and 3D CAD modeling best practices.
Experience with PLM systems (Arena or similar).
Hands-on prototyping and test experience - comfortable assembling and debugging systems in a lab.
Familiarity with hydraulics, actuators, sensors, and other mechatronic subsystems.
Ability to mentor junior engineers and provide technical direction to external firms.
Deep understanding of GD&T and tolerance stack-ups for precision assemblies.
Strong system-level thinking and ability to collaborate across disciplines.
Excellent problem-solving skills, with a data-driven approach to design decisions.
