Senior Chassis EngineerLocation:Riverside, CASalary Range: $110,000.00 - $140,000.00 Position SummaryThe Senior Chassis Engineer will own the mechanical integration and validation of axles, suspension interfaces, pneumatic and air brake systems, steering systems, and related vehicle systems for ENC's battery-electric (BEB), hybrid, diesel, CNG, and other transit bus platforms. This role requires broad vehicle systems knowledge and the ability to independently lead design, supplier coordination, prototype troubleshooting, and production release. The position will support battery-electric programs and transition across other ENC vehicle development programs and powertrain types as business priorities evolve. Primary responsibility for chassis frame and structural design remains with the Vehicle Structure Engineer; this position defines suspension, axle, brake, and steering loads, interfaces, and integration requirements.
Key ResponsibilitiesThis list of essential duties is not all-inclusive and may be expanded to include other duties, as management may deem necessary from time to time. The team member must be able to perform each essential job duty identified below satisfactorily. Reasonable accommodations may be made to enable qualified individuals with disabilities to perform the essential duties of this position unless doing so would create an undue hardship.
- Lead front/rear axle integration, mounting interfaces, load ratings, tire and wheel clearances, and weight-distribution considerations.
- Design and integrate suspension interfaces, air springs, shock absorbers, ride-height components, and related brackets and hardware, coordinating structural mounting design with the Vehicle Structure Engineer.
- Own pneumatic/air brake packaging, including reservoirs, lines, valves, brake chambers, compressor, dryer, and service access.
- Integrate steering gear, column, linkages, mounting structures, and related clearances; evaluate turning and articulation envelopes.
- Coordinate parking brake, hill-hold, and regenerative-braking interfaces with brake suppliers and electrical/controls engineers.
- Support system calculations, applicable FMVSS brake requirements, prototype installation, inspection, and validation.
- Develop and maintain 3D SolidWorks assemblies, manufacturing drawings, specifications, and system BOMs for assigned transit bus systems across BEB and other powertrain platforms.
- Own assigned systems from requirements and concept selection through packaging, design reviews, prototype build, validation, and production release.
- Coordinate technical interfaces with electrical, controls, structural, manufacturing, procurement, quality, and validation teams.
- Prepare engineering calculations, DFMEA inputs, DVP&R requirements, design changes, and technical documentation.
- Work directly with component suppliers to review technical data, CAD models, installation requirements, lead times, and design issues.
- Support hands-on prototype assembly, commissioning, troubleshooting, root-cause analysis, and production improvements.
Position Requirements - Bachelor's degree in Mechanical Engineering or a closely related engineering discipline is required; a master's degree in Mechanical Engineering or a closely related engineering discipline is preferred.
- Minimum 8 years of directly relevant chassis engineering, mechanical design, or vehicle systems integration experience in the medium- or heavy-duty vehicle industry, with demonstrated ability to independently lead technical design, supplier coordination, validation, and production release.
- Understanding of heavy-vehicle axles, steering geometry, suspension, air brakes, and pneumatic systems.Ability to evaluate mounting loads, packaging, clearances, installation and service requirements.
- Working proficiency in SolidWorks, mechanical drawings, GD&T, and assembly documentation.
- Experience coordinating with suppliers, manufacturing, validation, and vehicle controls teams.
- Strong system ownership, technical communication, troubleshooting, and project execution skills.
Preferred Qualification - Transit bus or medium- or heavy-duty commercial vehicle suspension and running-gear engineering experience.
- FMVSS 121 familiarity, brake validation, pneumatic schematics, and regenerative brake interfaces.
- Experience in vehicle dynamics, axle loading, ride-height, or steering performance is strongly desired.
Work EnvironmentThis is an onsite position based in Riverside, CA and requires being onsite.
