Starting with the Cosmic-1a system that installs solar panels 10x faster than today’s methods, our goal is to help transition the world to a clean energy future and laying the groundwork for the future of autonomous construction.\nThe Role\nWe are seeking a Senior Software Engineer in Calibration, Localization, and Mapping to lead the design, development, and implementation of performant and scalable state estimation algorithms that enhance the capabilities of our mobile manipulation robot.\nIn this role, you will take technical ownership of software that fuses data from lidar, inertial sensors, vision, and proprioception to estimate the robot’s ego-motion in its operating environment. You will work across the stack, balancing algorithmic performance, system constraints, and real-world reliability to deliver production-ready perception capabilities.\nResponsibilities\nDesign, develop, and integrate robust high-throughput low-latency state estimation, pose estimation, mapping, and reconstruction algorithms for real-world robotic systems\n\nBuild simulation-based and on-robot evaluation\n\nBuild and maintain algorithms and workflows for intrinsics and extrinsics sensor calibration as well as hand-eye calibration\n\nTranslate business and operational requirements into well-scoped technical work packages and execution plans\n\nCollaborate cross-functionally with controls, platform, and hardware engineers to ensure system-level success\n\nMaintain and elevate code quality through code reviews, automated testing, and documentation\n\nContribute to technical direction and engineering standards through strong leadership and adherence to best practices\n\nTravel to customer projects for on-site testing and deployment of robotic equipment in the field\n\nRequirements\nPhD or Master’s degree and 4+ years of applied research experience in Robotics, Electrical Engineering, Mechanical Engineering, Computer Science, or other related field\n\n5+ years of professional engineering experience\n\nExperience leading technical projects or small teams, including setting technical direction, coordinating execution, and mentoring other engineers\n\nFluency in modern C++ (C++17 or later), Python, and CUDA\n\nStrong mathematical skills, including deep understanding of 3D geometry, probability, and linear algebra\n\nDeep expertise in state estimation as on-manifold nonlinear least-squares, including SO(3)/SE(3) parameterizations, marginalization, and filter- and optimization-based techniques\n\nExcellent written and verbal communication skills\n\nThrives in ambiguity and incomplete information\n\nBonus\n8+ years of professional software engineering experience\n\nHands-on experience delivering production-grade ML models in latency-sensitive, edge-deployed systems\n\nUsing foundation models and simulation tools like Isaac Sim to accelerate data collection and model iteration\n\nOptimizing or compressing models using tools such as TensorRT\n\nManaging model lifecycles, including versioning, evaluation, and deployment\n\nExperience with 3D scene representations such as TRIPS, Gaussian Splatting, TSDF, or vector maps","description_format":"text","description_chars":3378,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Construction
