Sr. Mechanical Engineer, Hybrid Powertrain Seattle, WA

Job Description

Job Description

The Carbon Robotics Laser Weeder™ leverages advanced robotics, computer vision, AI/deep learning, and lasers to eliminate weeds with sub-millimeter accuracy—all without herbicides. This innovative solution reduces environmental impact, promotes soil health, and helps farmers address labor shortages and rising costs. Designed in Seattle and built at our cutting‑edge manufacturing facility in Richland, Washington, the Laser Weeder is setting a new standard for automated weed control.

With $157 million in funding from prominent investors such as BOND, NVentures (NVIDIA's venture arm), Anthos Capital, Fuse Venture Capital, Ignition Partners, Revolution, Sozo Ventures, and Voyager Capital
, Carbon Robotics is driving innovation.

As a no‑nonsense team with a bias for action, we take pride in executing our ideas. Whether it's designing transformative technology or visiting farms to ensure our products are reliable and safe, we do whatever it takes to deliver for our customers.

Working here means tackling big problems with big impact. You'll find opportunities to grow professionally, solve complex challenges, and make meaningful contributions to a mission that matters. At Carbon Robotics, we trust our team to act independently and make practical, real‑world decisions.

Join us as we innovate, execute, and build the future of farming together.

As a Sr. Mechanical Engineer, Hybrid Powertrain at Carbon Robotics
, you will play a key role in developing the mechanical systems that enable our diesel‑electric platform. You will immediately bring your significant experience integrating powertrain systems into vehicles and developing supporting systems such as gearboxes, generators, cooling systems, fuel management systems, and drivetrain components to revolutionize agricultural traction systems.

What you'll do:

• Define and select core off the shelf and semi‑custom components of the diesel electric powertrain including diesel engine, generator, ECUs, start/standby batteries, and more.
• Design/integrate complete diesel electric drivetrain systems including motor housings, gearboxes, and axle assemblies for high‑torque agricultural applications
• Architect thermal management solutions for motors, inverters, and battery systems operating in extreme agricultural environments
• Develop mounting structures and vibration isolation systems for diesel and electric motors ranging including traction drives to auxiliary pumps.
• Design/integrate power transmission components including couplings, driveshafts, and reduction gearboxes for 100+ kW electric motors
• Analyze and optimize powertrain efficiency through gear ratio selection, bearing design, and lubrication systems
• Lead durability testing including shock/vibration, thermal cycling, and accelerated life testing of drivetrain components
• Collaborate with electrical engineers on motor integration, cable routing, and high‑voltage safety enclosures

Knowledge, Skills, and Abilities for Success:

• 8‑15 years experience designing automotive or heavy equipment powertrains, preferably with electric or hybrid systems
• High proficiency in CAD (Solid Works) and FEA (ANSYS) tools for structural, thermal, and vibration analysis
• Extensive experience with rotating machinery design including shaft dynamics, bearing selection, and gear design
• Solid background in thermal management including liquid cooling systems, heat exchangers, and thermal interface materials
• Experience designing and integrating cast, machined, and fabricated housings for high‑precision rotating equipment
• Knowledge of automotive/agricultural durability requirements and validation testing procedures
• Familiarity with electric motor characteristics, efficiency maps, and integration requirements
• Experience with sealing systems for high‑speed shafts and contamination prevention in agricultural environments
• Highly desired to have past experience as a Responsible Engineer or IPT lead.
• Willingness to travel ~10% of the time to support products in the production & field environments with a demonstrated ability to work directly with internal and external stakeholders/customers
• BS+ in…
