Job description

About this role

Cyngn is seeking a Sr Mechanical Engineer who can own the mechanical design, integration, and release of major vehicle systems. This is a high-impact, technically demanding position where you will drive the development of core mechanical subsystems 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.

Responsibilities

• 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 product development cycles from concept to production, ensuring manufacturability and reliability
• Troubleshoot issues, identify root causes, and design corrective/preventative solutions
• Build, assemble, and operate 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 Electronics enclosures, harnesses, and sheet metal assemblies
• Own subsystem Bills of Materials (BOM), assembly structures, and documentation within PLM systems (Arena)
• Collaborate with program management to plan development schedules, builds, and resolve supply chain challenges

Qualifications

• 4~8 years of experience in mechanical engineering, ideally in robotics, automotive, or other complex electromechanical systems
• Proven record of taking products from concept through mass production
• Strong proficiency with SolidWorks and 3D CAD modeling best practices
• Understanding of GD&T and tolerance stack-ups for precision assemblies
• Experience with PLM systems (Arena or similar)
• Hands‑on prototyping and test experience — comfortable assembling and debugging systems in a lab
• Analysis skills for simple FMEA & Thermal simulations
• Ability to collaborate across disciplines
• Excellent problem‑solving skills, with a data‑driven approach to design decisions

Benefits & Perks

• Health benefits (Medical, Dental, Vision, HSA and FSA (Health & Dependent Daycare), Employee Assistance Program, 1:1 Health Concierge)
