About the job
Requirements
- A bachelor's degree or above in computer science, automation, electronics, robotics, vehicle engineering, mathematics, or a related major.
- At least 3 years of autonomous-driving perception or point-cloud algorithm development experience.
- Proficiency in C++ and Python, and familiarity with Linux and ROS/ROS2.
- Familiarity with deep-learning frameworks such as PyTorch, with a solid foundation in computer vision and deep learning.
- Practical implementation experience with mainstream 3D detection models such as PointPillars, SECOND, CenterPoint, and PV-RCNN.
- Familiarity with point-cloud semantic segmentation, instance segmentation, and occupancy methods, including models such as RangeNet++ and Cylinder3D.
- Familiarity with traditional point-cloud processing methods such as ground segmentation, Euclidean clustering, DBSCAN, and voxel filtering.
- Experience with model quantization, pruning, TensorRT/CUDA acceleration, and in-vehicle deployment.
- Familiarity with point-cloud and perception libraries including PCL, Open3D, OpenPCDet, and MMDetection3D.
- Ability to analyze large-scale test data and identify issues.
Responsibilities
- Develop and maintain 3D lidar object-detection models for mining trucks, light vehicles, construction equipment, people, and road obstacles.
- Develop point-cloud clustering, ground segmentation, semantic segmentation, and drivable-area detection algorithms for unstructured roads and irregular obstacles.
- Design and deploy multitask perception models, including detection, segmentation, and occupancy, to improve utilization of in-vehicle computing resources.
- Improve model robustness in mining environments with dust, rain, fog, vibration, and strong light, reducing false positives and false negatives.
- Support issue analysis, data feedback, and continuous model iteration and optimization during large-scale road testing.
- Quantize, accelerate with TensorRT, and deploy perception models on in-vehicle platforms such as NVIDIA Orin to meet real-time requirements.
Desired Qualifications
- Experience with autonomous driving in closed environments such as mines, ports, or industrial parks.
- Experience with multisensor fusion perception involving lidar, cameras, and millimeter-wave radar.
- Experience with point-cloud denoising or perception robustness optimization in adverse weather such as dust, rain, or fog.
- Experience with auto-labeling, active learning, or building data engines.
- Research or application experience in BEV perception, occupancy networks, or end-to-end perception.
About the company
Caterpillar makes construction and mining machines, diesel and natural gas engines, industrial gas turbines and locomotives for contractors, mines, energy companies and data center builders. It is the world's largest maker of construction and mining equipment, and its yellow Cat bulldozers and excavators work in nearly every country. Customers buy or rent machines through independent Cat dealers, while its engines and turbines generate electricity and push natural gas through pipelines. Caterpillar earns money from equipment sales and from the parts and repairs that dealers supply over a machine's working life. It was formed in 1925 when California's Holt and Best tractor companies merged, and it is based in Irving, Texas.

Simplify's Take
What believers are saying
- Data centers drive growth: power generation sales jumped 72% in the June 2026 quarter on demand for generators and turbines.
- Factory hiring is growing: a $1 billion North Carolina plant, announced September 2026, is expected to create 1,950 jobs.
- Recurring service work adds stability: parts and service brought in $24 billion in 2025, over a third of sales.
What critics are saying
- Tariffs keep getting costlier: in August 2026, Caterpillar forecast $2.2 billion of 2026 tariff costs, up from 2025's $1.8 billion.
- Patent fight threatens imports: in December 2025, rival Bobcat asked US trade regulators to ban some Cat loaders and excavators.
- Expect five office days a week: since June 2025, US office staff must come in daily, and attendance affects reviews.
What makes Caterpillar unique
- Power, not bulldozers, is its biggest business: engines and turbines brought in $28.6 billion in 2025, topping construction's $25.1 billion.
- It runs its own lender: Cat Financial's overdue loans fell to 1.31% in June 2026, the lowest since 1998.
- It also makes gas turbines: San Diego-based Solar Turbines builds 1 to 39 megawatt units for pipelines and power.
