Cell Labs Opportunities

We build humanoid systems: full stack, from hardware and electronics to software and manufacturing, all in-house in Berlin. At Cell Labs, we push the boundary of what robotics can achieve. Our goal is clear: to build systems that empower humans, not replace them. Our technology is already deployed with industry leading customers and partners. Now, our own product is close to launch. The quiet phase is over. We are looking for people who want to be here early, take ownership, and help us build what others only talk about. Location: Berlin (on-site) Start: Asap Employment Type: Full-time Tasks Mechanical Design & CAD: Design and develop mechanical components and assemblies for humanoid systems, from actuators and kinematic mechanisms to sensor mounts and protective enclosures and model them in CAD (e.g. Onshape). Actuator Kinematics: Design and optimize the kinematic structure of the robot's joints and limbs, including joint layouts, degrees of freedom, ranges of motion, and transmission mechanisms. Select and integrate actuators (motors, gearboxes, encoders) so that torque, speed, and load requirements are met across the full motion range. Production Readiness: Optimize designs for series production with product requirements, user experience, and target cost in mind. Prepare the handover to manufacturing, including assembly processes, jigs and fixtures, and supplier ramp-up. Prototyping & Testing: Prototype and validate mechanical systems for performance, safety, and durability. Design and build test rigs for actuators and subassemblies, including endurance and load testing. Electronics Integration & Wiring: Integrate PCBs, sensors, and batteries into mechanical assemblies, including cable routing and heat management. Build and solder cables and wiring harnesses for prototypes and test setups. Analysis & Materials: Run stress analysis and weight optimization to improve performance and longevity. Research, test, and qualify new materia
