About the role

Hands-on robotics role focused on setting technical direction for Reactor's robotics work, getting customer models running with strict latency budgets on real robots, and integrating robot stacks with Reactor's inference platform.

Responsibilities

  • Serve robot policies (VLAs, IL/RL models) on GPUs under robot-grade latency budgets, and profile the full path from input tensor to output action
  • Build the integration layer between Reactor and robot stacks: ROS/ROS2 nodes and bridges, transport, and low-latency channels carrying observations up and actions down
  • Use world models for policy evaluation, and tune how we serve rollouts for throughput, fidelity and turnaround time
  • Bring teleoperation and human-in-the-loop experience to our real-time transport: synchronization, jitter and failover for a live control loop
  • Debug with customer robotics teams across the whole loop: sensor capture, network, inference, action output, robot execution
  • Help shape the technical roadmap and set the engineering bar for the team around you

Qualifications

  • You've run learned policies or ML models on real robots or autonomous systems, and debugged failures from perception through policy, control and hardware
  • Strong ML understanding. You know how modern robot policies (VLAs, imitation learning, RL) and world models are built (transformer backbones, action tokenization or diffusion heads, observation encoders) and how they behave at inference time. You won't be training them.
  • Depth on inference systems: batching and scheduling, GPU utilization, p99 latency vs. throughput, and running models in real time against physical systems
  • Strong C++ and Python in production, and comfortable changing performance-critical code
  • Working experience with ROS/ROS2, DDS and robot middleware, from message definitions to transport QoS settings
  • Range across ML, systems, cloud infra, networking and robotics. You'd rather fix whatever's blocking the robot than stay in one layer.
  • The judgment to lead: setting direction, making tradeoffs explicit and representing Reactor in front of customer engineering teams
