Machine Learning Engineer, Perception R&D

About this role:

Pickle is on the hunt for a dynamic and driven Machine Learning Engineer to revolutionize the future of warehouse automation. This role sits at the critical intersection of Perception and MLOps. You will focus on two key pillars: developing robust scene understanding models and building the deployment and analysis infrastructure that allows us to measure, understand, and improve our robots performance in the real world.

• Build Performance Analysis Systems:
  You will design systems that automatically analyze robot telemetry and video logs to detect anomalies, quantify perception failures, and provide deep insights into why a robot performed a certain way.
• Scale the Data Engine:
  You will take ownership of the data lifecycle. You will build automated pipelines to mine interesting events from fleet data, implement active learning strategies to curate high-value datasets, and drive the continuous improvement of our model suite.
• Develop Scene Understanding Models:
  You will train and refine 2D/3D vision models specifically designed for event detection and semantic understanding.
• Master Edge Deployment:
  You will own the optimization and deployment of these models. You will use tools like Tensor
  
  RT and ONNX to ensure our models run efficiently on edge hardware (NVIDIA Orin).
• Define Perception Metrics:
  You will move beyond simple validation loss and define real-world performance metrics that correlate with customer success, visualizing these trends for the broader engineering team.

• 3+ Years of Experience in Computer Vision and Machine Learning, with a strong focus on MLOps, deployment, or data infrastructure.
• Strong proficiency in Python and PyTorch. You are comfortable writing tooling scripts, data queries, and deployment pipelines.
• You have experience optimizing models for the edge using Tensor
  
  RT, ONNX Runtime, or CUDA. You understand how to profile model performance and manage resource constraints.
• You treat data as a product. You have experience utilizing SQL, data lakes, or vector databases to manage large-scale datasets and automate quality assurance.
• Familiarity with VLMs and 2D/3D Vision architectures sufficient to debug model failures and understand data needs.
• You can 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.
