Robotics Engineer III - Motion Planning ArcBest - 3.6 Fort Smith, AR Job Details Full-time 1 day ago Qualifications Software engineering Reinforcement learning Control system design Programming languages Math Technical research projects Navigation systems System development Robot vision Full Job Description Job Description The Robotics Engineer III - Motion Planning leads the development, optimization, and large-scale deployment of motion planning architectures for fleet-wide AMR navigation. This position focuses on high-performance optimization, AI-driven behavioral planning, fail-safe recovery strategies, and large-scale robotic coordination. The Robotics Engineer III - Motion Planning designs and refines graph search, optimization-based planners, and reinforcement learning-based motion strategies while ensuring seamless integration with perception and real-time control. Responsibilities Architect scalable motion planning frameworks for fleet-level AMR deployments. Develop and refine AI-driven motion planning (reinforcement learning, imitation learning, deep MPC). Implement real-time model predictive planners using CasADi, ACADOS, and convex/non-convex solvers. Design and implement advanced fail-safe motion planning strategies, including autonomous re-routing, recovery-based motion primitives, and redundant planning checks. Enhance multi-agent coordination strategies for large-scale robotic path planning and collision avoidance. Decompose complex behaviors into modular, reusable tree structures. Integrate graph-based, hierarchical, and predictive planning models for decision-making. Deploy AI-based planning models (e.g., learning-based cost functions, uncertainty-aware planners). Conduct large-scale simulation and on-robot validation to assess real-time system performance. Optimize cost-aware, energy-efficient, and high-speed trajectory planning for AMRs. Ensure robust software development, CI/CD implementation, and fault-tolerant motion control strategies. Lead cross-functional collaborations and mentor junior engineers in robotics motion planning. Other duties and projects, as assigned.
