Senior Perception Software Engineer

About this role: Pickle is on the hunt for a dynamic and driven Senior Perception Software Engineer to revolutionize the future of warehouse automation. This role will focus on working heavily with 3D LiDAR and other multi-sensor arrays to tackle complex challenges in state estimation, scene perception, mapping, and localization. You will play a crucial part in writing robust, production-grade software that translates raw sensor data into actionable intelligence for our robots operating in dynamic, real-world unloading docks. What You’ll Accomplish: Drive the accuracy and precision of our localization and state estimation pipelines. You will ensure reliable pose estimation of the robot's mobile base and scene components. Develop advanced obstacle mapping for collision avoidance that thrives in messy environments. Implement and optimize point cloud processing algorithms tailored for real-time edge compute. Architect a robust software stack that efficiently parses and interfaces with the outputs of our machine learning models, integrating novel perception pipelines seamlessly into the core production codebase. Improve and automate multi-sensor calibration routines. You will manage tolerance stacks and ensure high-fidelity spatial alignment across our sensor suites to guarantee a single source of truth for the robot. Who You Are: 5+ years of experience in robotics software engineering (or an MS with 3+ years of highly relevant industry experience). Exceptional software engineering fundamentals, highly proficient in Python and C++ for production systems. Strong mathematical foundation in linear algebra, geometry, and probabilistic robotics. Hands-on experience building perception stacks using industry-standard tools and frameworks, including ROS/ROS2, OpenCV, Open3D, Eigen, and Git. Hands-on experience with sensor stacks including 3D LiDARs, IMUs, and cameras. You are a "full-stack" robotics engineer who cares about accuracy, precision, and edge cases in the physical world and can articulate architectural trade-offs to drive the best system level decisions. Experience with optimization libraries (Ceres Solver, GTSAM), parallel computing (CUDA), Docker, and PCL preferred. Willing and able to work from our HQ in Charlestown, MA, at least 3 days a week.
