Full Job Description
Apptronik is a human-centered robotics company developing AI-powered robots to support humanity in every facet of life. Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond. We operate at the cutting edge of embodied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better. The Role Apptronik is seeking a Staff Mechanical Engineer – Thermal Simulation Analysis to lead the thermal architecture of our humanoid robot, Apollo. In a humanoid system, high-power actuators, high-performance compute clusters, and dense battery packs are packed into tight, mobile volumes—creating one of the most challenging thermal environments in robotics. As a Staff Engineer, you are the technical authority for the entire "thermal stack". You will move beyond simple steady-state analysis to model complex, transient thermal events during high-intensity robot maneuvers. You will influence the robot's physical architecture from the concept phase, ensuring that we maximize performance and duty cycle without compromising safety or hardware longevity. Key Responsibilities ● Thermal Architecture Leadership: Own the thermal roadmap for the humanoid platform. Define the cooling strategies (passive, active, or phase-change) for high-torque actuators and high-density compute enclosures. ● High-Fidelity Simulation: Develop complex CFD (Computational Fluid Dynamics) and heat transfer models using industry-standard tools (e.g., Ansys Icepak/Fluent, Simscale, or). ● Transient Duty Cycle Modeling: Predict thermal behavior during dynamic robot activities (walking, lifting..) where power consumption varies r
