That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND‑01 Alpha - our rapidly developed humanoid platform now running in real industrial pilots - and we’re growing the team to take it even further. ### About the Role We are looking for a Senior **Low-level Control Engineer** to join our **Control Team** in London, focusing on control development and integration for our **end-effectors**. You will design, implement and validate **actuator- and joint-level controllers** and **grasp-level behaviours** across a family of end-effector variants - parallel and multi-finger grippers, vacuum and suction tooling, and purpose-built tooling for specific customer tasks. Each variant brings different actuation, different sensing and, critically, **different transmission mechanisms**: geared direct drives, cable- and tendon-driven routings, differential and coupled linkages, and underactuated designs where few actuators must produce adaptive, compliant grasping across many degrees of freedom. The ideal candidate has a **solid background in control theory**, strong **software engineering skills in C++**, and comfort working from real-time embedded control up through kinematics/dynamics and hardware debugging. You will work closely with mechanical and hardware engineers - early enough in the design cycle that your input shapes actuation and transmission choices rather than merely inheriting them. ### What You'll Do **Low-Level Control Development:** - Tune and validate actuator- and joint-space control loops (PID, feedforward, impedance/admittance, observers, state feedback) for multi-DoF end-effectors in ROS2. - Develop grasp-level behaviours: grasp force control, compliant closing, slip detection and correction, and adaptive grasping on underactuated grippers. - Implement safety and fault-handling mechanisms — thermal and over-current protection, stall and jam detection, grip-loss detection, safe behaviour on fault.**Transmission Mechanisms, Modeling & System Identification:** - Build and identify models of actuators, transmissions and mechanisms - geared, cable/tendon-driven, differential, coupled and underactuated - including compliance, friction, backlash, hysteresis, cable stretch and pretension effects. - Own the joint-to-actuator abstraction for these mechanisms and the correct exposure of joint versus actuator state through the control stack. - Contribute directly to transmission mechanism design: work with mechanical engineers on routing, reduction ratios, DoF coupling and underactuation strategy, bringing the controllability and observability consequences of each option into the conversation early.**Sensor & Hardware Integration:** - Integrate and calibrate end-effector sensing (F/T, tactile, encoders, temperature/current, vacuum feedback) with real-time acquisition across the control stack. - Hands-on bring-up and debugging of new end-effectors, including test-stand work and vendor-supplied units.**Cross-Disciplinary Collaboration:** - Close the loop with mechanical/electronics engineers across sites on actuation, transmission and sensing requirements. - Work with data collection, applications and deployment teams so end-effectors work reliably in real use. ### What We're Looking For - Shipped real-time-safe, object-oriented C++ control software running on real hardware. - Tuned and validated controllers on physical actuators, including sensor calibration and bring-up. - Modelled, identified and controlled through real mechanical transmissions - gearing, cables/tendons, differentials, coupled linkages or underactuated mechanisms - and dealt with the compliance, friction and backlash they introduce. - Worked on end-effectors or comparable multi-DoF mechanisms, including grasp control and supporting sensing. - Debugged at the fieldbus and OS layer: e.g. EtherCAT or CAN, on an RTOS or real-time Linux. - Strong control theory foundation (linear/nonlinear control, stability, observers, state estimation, feedback/feedforward, filtering, frequency-domain analysis) applied to multi-DoF mechanisms via Jacobians, numerical IK/FK, and URDF/Xacro.*Nice to have:* - BLDC motor control (commutation, current control, torque optimization). - ros2_control internals (hardware interfaces, controllers, controller_manager, plugins, lifecycle nodes). - Tendon- or cable-driven mechanisms specifically, including pretension management, routing friction and wear behaviour. - Tactile sensing integration; vacuum and suction tooling, including multi-cup arrays and grip-loss handling. - System identification toolchains and simulation environments (MATLAB/Simulink, MuJoCo, Isaac Sim). ### What We Offer - Competitive equity: stock options with meaningful upside as we scale. - 30+ paid days off, including 23 days of annual leave, all UK bank holidays, and additional company closure days (including Christmas–New Year shutdown). - Private healthcare, including virtual and in-person care. - Pension scheme with 8% total contribution (5% employee, 3% employer) on full earnings. - Free daily breakfast, catered lunch, and snacks in-office. - Work at the frontier - collaborate daily with world-class engineers, researchers, and product experts building the next generation of AI and humanoid robotics. - Real ownership - direct access to founding leadership, meaningful input on product direction, and the ability to drive key initiatives from day one. --- Source: Humanoid's own career page, read by RemJobs.
