Requirements
  • 5+ Years of Experience in Computer Vision and Machine Learning, with a track record of shipping ML products to the physical world (Robotics, AV, or IoT).
  • Expert-level Python and PyTorch skills. Working knowledge of C++ for deployment and system integration.
  • Experience with 2D Vision (YOLO, MaskRCNN, Transformers) and 3D Vision (PointNet, grasp generation, multi-view geometry, camera calibration).
  • Proficient with inference optimization tools such as TensorRT, ONNX Runtime, or CUDA to maximize hardware utilization.
  • Experience curating large-scale datasets, detecting statistical bias, and automating quality assurance within the ML pipeline.
  • Ability to translate high-level product requirements into specific engineering tasks and explain technical trade-offs to non-expert stakeholders.
  • Familiarity with Docker, AWS/GCP (S3, EC2), labeling platforms and experiment tracking tools.
Responsibilities
  • Architect Multi-Modal Vision Systems: You will design and train models that fuse 2D inputs with 3D geometry to solve complex grasping and scene understanding tasks.
  • Lead End-to-End Model Deployment: You will own the transition from research to reality. This includes model graph optimization, quantization (TensorRT), and runtime integration to ensure low-latency inference on our edge compute hardware (NVIDIA Orin).
  • Drive Technical Excellence: As a senior member of the team, you will conduct rigorous code reviews, mentor junior engineers, and contribute to the strategic perception roadmap.
  • Own the Data Strategy: You will take ownership of our existing labeled dataset and pipeline. You will identify bottlenecks, improve data quality, implement active learning strategies to systematically resolve edge cases and improve model robustness.
  • Ensure Production Reliability: You will write high-performance production code (Python/C++) to seamlessly integrate perception outputs into the broader robotic control stack, prioritizing safety and system stability.

Pickle Robot develops dock-side robots that help unload trucks and containers at warehouse loading docks for logistics and e-commerce operations. The robots work alongside human workers, using sensors and software to plan and execute unloading tasks, reducing physical strain and increasing throughput. They differentiate themselves by focusing specifically on dock unloading, offering options to own or lease the robots plus ongoing maintenance and software services. The goal is to improve safety and efficiency at loading docks, enabling faster unloading and less fatigue for workers.

Simplify's Take

What believers are saying

  • Secured orders for 30+ robots from six customers deploying early 2025.
  • Raised $50M Series B from Teradyne, Toyota Ventures for commercialization.
  • Yusen Logistics partnership streamlines container unloading, boosts safety.

What critics are saying

  • Amazon Robotics' 750,000 robots block 40% e-commerce market share now.
  • Osaro's systems in 50+ sites like DHL outpace Pickle's palletizing in 12 months.
  • Agility Robotics' Digit pilots with GXO obsolete single-arm design by 2027.

What makes Pickle Robot unique

  • Dill robot unloads trucks at 600+ boxes per hour using generative AI and machine vision.
  • Physical AI enables human-scale manipulation of non-palletized goods in chaotic trailers.
  • KUKA arms with proprietary grippers achieve human-or-better picking speeds alongside humans.
