Senior Mechanical Engineer – Thermal Simulation & Analysis
About The Position
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.
Requirements
- Strong proficiency in CFD tools (e.g., Ansys Icepak, Fluent, or similar)
- Solid understanding of heat transfer principles: conduction, convection, and radiation
- Experience with transient thermal modeling and real-world duty cycles
- Ability to perform first-order thermal calculations to guide design decisions
- Strong cross-functional collaboration and communication skills
- Experience working with physical hardware and test environments
- Bachelor’s or Master’s degree (or equivalent) in Mechanical Engineering or related field
- At least 5–8 years of experience in thermal design and simulation for electromechanical systems
Responsibilities
- Design and develop thermal management solutions (passive and active) for actuators, compute systems, and battery packs
- Build and execute CFD and heat transfer simulations to guide design decisions
- Perform transient thermal analysis for dynamic robot operation and varying duty cycles
- Collaborate cross-functionally with mechanical, electrical, and controls teams to integrate thermal solutions
- Supports test plan creation by identifying critical thermal scenarios from CFD and transient models and defining corresponding instrumentation and test procedures.
- Mentor junior level engineers and act as the technical escalation point for hardest problems.
- Correlate simulation results with physical test data and refine models accordingly
- Contribute to material selection (TIMs, heat spreaders, alloys) balancing performance, weight, and cost
- Develop and document thermal design guidelines and best practices
