US H-1B: cap-subject employers enter a lottery weighted by wage level — Level I gets 1 entry, Level IV gets 4 (DHS projected selection odds ≈15% at Level I to ≈61% at Level IV). Universities and non-profit research employers are cap-exempt. The $100,000 fee for new petitions from abroad is currently blocked by a court order (appeal pending).

About the role
About the Team Our Robotics team is focused on unlocking general-purpose robotics and pushing towards AGI-level intelligence in dynamic, real-world settings. Working across the entire model stack, we integrate cutting-edge hardware and software to explore a broad range of robotic form factors. We strive to seamlessly blend high-level AI capabilities with the constraints of physical systems to improve peoples’ lives. About the Role We are seeking an Electrical Engineer to build and own the electrical backbone of our robotic actuator dynamometer and test infrastructure. You will design, integrate, and operate the load motor drives, power distribution, instrumentation wiring, DAQ interfaces, and safety systems that make high-performance robotic actuator testing repeatable, safe, and scalable. This role spans hands-on lab execution and system architecture: selecting and commissioning power electronics, designing robust test-cell electrical systems, bringing up sensors and DAQ, and partnering with mechanical and software engineers to turn robotic actuator hardware into trustworthy data. In this role, you will - Own the electrical architecture of dynamometer and actuator test cells, from mains distribution and protection through load motor drives, braking, and auxiliary power. - Specify, integrate, commission, and tune motor drives and load machines for robotic actuator torque, speed, efficiency, thermal, and durability testing. - Design power distribution, grounding, shielding, cable routing, and connectorization for high-current, high-voltage, and low-level measurement systems. - Integrate torque, position, speed, temperature, voltage, current, vibration, and other instrumentation from robotic actuators into DAQ and control systems. - Develop electrical schematics, wiring diagrams, panel layouts, harness documentation, and test-cell interface definitions. - Build, debug, and maintain test-cell electrical hardware, rapidly diagnosing noise, EMI, grounding, drive, sensor, and power-quality issues. - Design and validate safety circuits including E-stops, interlocks, contactors, safe torque off, guarding interfaces, and fault detection. - Partner with mechanical engineers on packaging, cooling, fixturing interfaces, and serviceability of test infrastructure. - Partner with software and controls engineers on I/O maps, real-time signals, calibration, automated sequences, and reliable data capture. - Establish commissioning, calibration, inspection, and preventive-maintenance procedures for lab electrical systems. - Evaluate vendors and components for drives, motors, sensors, DAQ hardware, protection devices, and electrical enclosures. - Analyze test and diagnostic data to improve measurement quality, cell uptime, and hardware reliability. - Set practical electrical standards that enable a growing dyno lab to operate safely and consistently. You might thrive in this role if you Have strong intuition for power electronics, motor drives, electrical safety, and precision measurement in noisy electromechanical environments. - Enjoy being hands-on in the lab: wiring, probing, commissioning, debugging, and improving real hardware. - Can move comfortably between system-level architecture and detailed electrical implementation. - Care about clean grounding, shielding, calibration, and signal integrity because trustworthy data depends on them. - Are comfortable working with evolving hardware and creating structure in a fast-moving environment. - Take ownership of safety and operational reliability, not just a schematic or subsystem. - Communicate clearly across electrical, mechanical, controls, software, facilities, and operations teams. - Balance engineering rigor with rapid iteration and pragmatic lab
