Full time
At Mentee Robotics, we are redefining humanoid automation with an AI-first approach - combining perception, reasoning, and dexterous manipulation into fully autonomous systems that continuously learn and adapt. 在 Mentee Robotics，我们以 AI 优先的理念重新定义人形机器人自动化——将感知、推理与灵巧操作融合为能够持续学习与自适应的全自主系统。 We are now expanding with a new robotics Engineering Center in China, working hand-in-hand with our engineering teams in headquarters. Its mission: to rapidly develop our next-generation full-size humanoid and bring it to life - a walking, working platform that becomes the foundation of our next generation of products. This is a small, senior, hands-on team where speed of iteration is the core value. 我们正在中国设立全新的机器人工程中心，与总部的工程团队紧密协作。其使命是：快速研发我们下一代全尺寸人形机器人并使其落地——一个能行走、能工作的平台，成为我们下一代产品的基础。这是一支精干、资深、亲力亲为的团队，迭代速度是其核心价值。 We are looking for two hands-on Embedded Engineers to own everything that runs on the Motor Controller PCB - jointly with our Motion Control Engineer, who designs the control algorithms you will implement. This is close-to-the-metal, critical-path firmware: bare-metal real-time code where a missed deadline is a fallen robot. 我们正在寻找两位擅长实操的嵌入式工程师，负责运行在电机控制器 PCBA 上的一切——与我们的运动控制工程师共同协作，由其设计你将实现的控制算法。这是贴近底层、位于关键路径的固件：裸机实时代码，一次错过截止时限就意味着机器人摔倒。
