Embedded Engineer - Motor Control Firmware 嵌入式开发工程师

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., * Design and develop real-time firmware in C for the STM32-class MCU on the Motor Controller PCB - bare metal, no OS

• Implement and optimize the control algorithms defined by the Motion Control Engineer: FOC commutation and current/velocity/position loops, with guaranteed loop timing
• 实现并优化运动控制工程师定义的控制算法:FOC 换相以及电流/速度/位置环,并保证环路时序
• Own calibration routines (encoder offset, current sensing), protections, and fault handling (over-current, over-temperature, encoder loss)
• 负责标定流程(编码器偏置,电流采样),各类保护以及故障处理(过流,过温,编码器丢失)
• Implement the EtherCAT/CAN slave stack and the joint-level communication API exposed to the robot's compute platform
• 实现 EtherCAT/CAN 从站协议栈,以及向机器人计算平台开放的关节级通信 API
• Own bootloader, flashing, and fleet firmware-update flow across all joints
• 负责所有关节的Bootloader,烧录以及批量固件升级流程
• Work with high-speed peripherals: ADCs, DMA, timers/PWM, interrupts
• 使用高速外设:ADC,DMA,定时器/PWM,中断
• Bring up new board revisions with the electrical engineer; debug with logic analyzers, oscilloscopes, and HIL setups

• B.Sc. in Electrical Engineering, Computer Engineering, or a related field
• 电气工程,计算机工程或相关专业学士学位
• 8+ years of embedded firmware development in bare-metal, hard real-time systems
• 8年以上裸机,硬实时系统的嵌入式固件开发经验
• Strong proficiency in C and STM32 (or equivalent ARM Cortex-M) programming
• 精通 C 语言以及 STM32(或同类 ARM Cortex-M)编程
• Hands-on experience with motor control firmware (FOC, current/velocity/position loops, encoder interfaces) and/or industrial protocols (EtherCAT, CAN)
• 具备电机控制固件(FOC,电流/速度/位置环,编码器接口)和/或工业协议(EtherCAT,CAN)的动手经验
• Excellent debugging skills in both code and hardware environments
• 在代码与硬件环境中均具备出色的调试能力
• Comfortable with schematics, datasheets, and bench instrumentation
• 能够熟练查阅原理图,数据手册并使用测试台仪器

Advantages加分项

• Deep EtherCAT knowledge, including slave stack integration and real-time tuning
• 深入掌握 EtherCAT,包括从站协议栈集成与实时调优
• Experience with servo drives, drone ESCs, or robot joint controllers
• 具备伺服驱动器,无人机电调或机器人关节控制器方面的经验
• Exposure to Python for test automation
• 接触过用于测试自动化的 Python
• Familiarity with MISRA C or structured safety-oriented code practices
• 熟悉 MISRA C 或结构化,面向安全的代码实践
• Comfortable communicating technical topics in English with international teams
