固件工程师

Responsibilities

• Diagnose faults in electrical, electronic, communication, control and embedded systems of prototype, test, production and field equipment using a systematic, evidence-based approach.
• Design, develop and deliver high- and low-voltage power distribution and control systems, including contactors, relays, sensors, actuators and related harnesses.
• Create and update electrical schematics, wiring tables, harness drawings, panel designs, connector specifications and bills of materials for integrated system and subsystem architectures.
• Define, guide and release firmware versions for prototypes and series production; program, load, verify and test firmware on embedded microcontrollers and electronics.
• Manage software and hardware configuration changes (parameter tuning, calibration updates, network settings, controller configuration) with full traceability and documentation.
• Capture and analyze data logs (fault codes, waveforms, network traffic) via CAN, Ethernet and serial interfaces to perform root cause analysis of major diagnostics.
• Develop and maintain PLC software and HMIs for equipment control, test benches and infrastructure support.
• Troubleshoot electrical issues and verify system safety and performance using oscilloscopes, multimeters, logic analyzers, power analyzers and insulation testers.
• Plan and conduct bench, subsystem, machine and commissioning tests, documenting results to demonstrate compliance with design requirements and acceptance criteria.
• Lead investigations of complex software-hardware interactions to identify, implement and release effective corrective and preventive actions.
• Provide hands-on support for wiring, harness modification, firmware updates and diagnostic methods in manufacturing, production and field environments, ensuring compliance with safety standards.
• Collaborate with firmware developers, systems engineers, manufacturing staff, suppliers and service personnel to resolve technical issues, enhance diagnostics and improve product design.

Must Have

• Bachelor's degree in Electrical Engineering, Electronics Engineering, Mechatronics Engineering, Control Engineering or a related engineering field.
• At least three years of experience with electrical equipment, embedded controllers, industrial automation, mobile machinery or electromechanical systems.
• Solid grasp of DC/AC circuit theory, power distribution, protection systems, grounding practices, isolation techniques and electrical safety standards.
• Hands-on experience with PLC programming (ladder logic, structured text, function blocks) and embedded controllers (I/O systems, sensors, actuators, state-based control methods).
• Familiarity with communication protocols for commands, diagnostics and data exchange, including CAN, Ethernet and serial interfaces.
• Ability to read and write technical documentation, including electrical schematics, wiring tables, harness drawings, panel layouts and component datasheets.
• Hands-on skills in electrical/electronic lab work, including live testing, wiring, instrumentation and prototype evaluation.
• Familiarity with engineering configuration control, version management, development documentation and test evidence traceability.
• Analytical mindset to identify complex interactions between hardware and software and critically evaluate field conditions.
• Excellent English and Chinese communication skills for collaboration with multidisciplinary teams.

Preferred

• Experience with battery-electric mining equipment, off-road heavy machinery, battery infrastructure and industrial power systems.
• Knowledge of high-voltage technology, battery management systems, inverters, motors, power converters, chargers, insulation monitoring and interlock systems.
• Familiarity with embedded programming languages such as C, C++ and Python for diagnostics, testing and prototyping.
• Familiarity with embedded Linux, real-time operating systems, debugging tools, build systems and firmware release management.
• Hands-on experience with CAN analysis and calibration tools, diagnostic databases, message decoding and parameter management.
• Experience with PCB design/inspection, including schematic review, board debugging, component selection, soldering, rework and failure analysis.
• Knowledge of hardware-in-the-loop testing, automated test systems, embedded Linux, model-based development and functional safety standards.
• Understanding of electromagnetic compatibility (EMC), machinery safety regulations and electrical standards relevant to industrial/mobile equipment.
• Familiarity with infrastructure electrical equipment such as switchgear, transformers, rectifiers, energy storage devices and industrial distribution panels.
