Senior Mechanical Engineer

About Cyngn, Inc.

Based in Mountain View, CA, Cyngn is a publicly-traded autonomous technology company. We deploy self-driving industrial vehicles -specifically autonomous tuggers -  to factories, warehouses, and other facilities throughout North America. To build this emergent technology, we are looking for innovative, motivated, and experienced leaders to join us and move this field forward. If you like to build, tinker, and create with a team of trusted and passionate colleagues, then Cyngn is the place for you.

Key reasons to join Cyngn:

We are small and big.

With under 100 employees, Cyngn operates with the energy of a startup. On the other hand, we’re publicly traded. This means our employees not only work in close-knit teams with mentorship from company leaders—they also get access to the liquidity of our publicly-traded equity.

We build today and deploy tomorrow.

Our autonomous vehicles aren’t just test concepts—they’re deployed to real clients right now. That means your work will have a tangible, visible impact.

We aren’t robots. We just develop them.

We’re a welcoming, diverse team of sharp thinkers and kind humans. Collaboration and trust drive our creative environment. At Cyngn, everyone’s perspective matters—and that’s what powers our innovation.

About the role

• We are searching for a Senior Mechanical Engineer to join our team. You will own mechanical design and release for our autonomous industrial vehicles and the equipment they tow — structures, drivetrain and drive-unit integration, mechanisms, enclosures and sheet metal — from concept through engineering, design and production validation builds to production release. The vehicle engineering team is small and growing, and this hire adds a second mechanical design stream so that we can develop new vehicle programs in parallel with the ones we are launching.
• You are a generalist who has shipped a vehicle or a large electromechanical machine. You have sized motors, gearboxes and brakes against real load cases, designed the weldment they bolt to, released the drawings, argued with the fab shop about tolerances, and then built and broken the first prototype yourself. Robotics, automotive, off-highway or material handling — the domain matters less than the habit of owning the whole mechanical problem, from the first sketch to the production change order.
• You are drawn to a small team where the design you release in one quarter is driving on a test lot the next. You treat the environment the machine lives in — sealing, drainage, thermal, dust and rain — as design inputs, not afterthoughts. You are comfortable making trade-offs with incomplete information, writing them down, and revisiting them when the test data comes back. You treat electrical, firmware and autonomy engineers as peers, and you think about harness routing, sensor sight-lines and service access while the frame is still a sketch.
• You move fast but release cleanly: GD&T, tolerance stacks and DFM feedback are part of how you design, not a step afterwards. You are hands-on in the lab, direct in design reviews, and you mentor by review and by example.

What you'll do

• Own the mechanical technical specification, design, integration and release of vehicle systems: frame and structure, mounting and integration of supplier drive units and axles, wheel ends, braking, hitching and tire packaging, with structural analysis for industrial tow loads and duty cycles.
• Lead drive-system and long-lead component trade studies with electrical and firmware (supplier drive units, torque / grade / brake performance, battery packaging) and drive those decisions to purchase orders on the program schedule.
• Design product variants as one platform — common structures and a single bill of materials with configuration-specific options — so that variants are released, built and certified from one design.
• Own environmental readiness of the mechanical design: enclosure and compartment sealing, drainage, thermal paths, cable entries and connector selection, and the design-for-test needed to pass ingress, vibration, shock and temperature testing.
• Co-design operator-interface hardware and service-access features with electrical: hand-held control hardware (grip, controls, sealing, cable management and docking) and the features technicians will use every day.
• Own mechanical design for towed equipment and attachments — frames, steering geometry and tracking, powered conveyance, couplers and guarding — from first prototype through production release.
• Release drawings, GD&T, tolerance stacks and fabrication packages; partner with weldment, sheet-metal, machining and molded-part suppliers on quotes, DFM and first articles, and with our contract manufacturer on work instructions and engineering changes.
• Lead the mechanical side of prototype builds and redesign loops across engineering, design and production validation; own the change list and design freezes; build the test fixtures your mechanisms need; support system test and root-cause field issues from customer deployments.
• Serve as design release engineer for electronics enclosures, harness mechanicals and sheet-metal assemblies; own the subsystem bills of materials, assembly structures and documentation in PLM (Arena), and plan builds, long-lead parts and supply-chain risks with program management and operations.

Qualifications

• BS or MS in Mechanical Engineering (or equivalent experience) and 5+ years designing electromechanical systems in robotics, automotive, off-highway, material handling or a similar field.
• Has taken at least one vehicle-level or large electromechanical product through engineering, design and production validation phases to production.
• Expert in 3D CAD (SolidWorks or equivalent), FEA fundamentals, drawings, GD&T and tolerance analysis.
• Motor / gearbox / brake sizing, load-case and duty-cycle analysis; steering and suspension geometry fundamentals; experience integrating supplier drive units or transaxles.
• Weldment, sheet-metal, machined and molded-part design with hands-on supplier and DFM experience; experience designing for ingress protection, vibration and harsh environments.
• Hands-on: builds and debugs own prototypes; comfortable in a vehicle lab, on a test lot and at a supplier.
• Analysis skills for DFMEA and first-order thermal and structural simulation; data-driven design decisions.
• Experience with PLM systems (Arena or similar) and release discipline: BOMs, assembly structures, ECOs.
• Clear communicator who documents trade-offs and decisions; works well with electrical, firmware and software peers.

Bonus Qualifications

• Tow tractors, AGVs/AMRs, forklifts or outdoor industrial vehicles.
• Traction-drive and transaxle suppliers and 48 V electric powertrains; brake and parking-brake systems.
• Thermoformed, rotomolded or RIM enclosure design; sealed electronics enclosures (IP65–IP67).
• Functional-safety and industrial-truck standards exposure (ISO 3691-4, UL 583 / UL 3100, ANSI/ITSDF B56.5).
• Contract-manufacturer hand-off and production ramp support.
• Characterizing sensing systems (encoders, sensors) for closed-loop motor control.

Benefits & Perks

• Health benefits (Medical, Dental, Vision) through Aetna, Kaiser Permanente, and Guardian, with multiple plan tiers to choose from
• Ancillary benefits including accident, critical illness, and hospital indemnity plans (Voya)
• Company-paid basic life insurance, plus voluntary (supplemental) life for you and your dependents
• Short-term and long-term disability insurance
• HSA and FSA (Health & Dependent Daycare)
• Employee Assistance Program
• 1:1 Health Concierge
• Company 401(k)
• Commuter Benefits
• Flexible PTO policy
• Paid Parental Leave
• Daily lunches for in-office employees and fully-stocked kitchen with snacks and beverages
