Job Description


Position Overview

Seeking an experienced Senior Embedded Systems & Software Engineer to lead the design, development, and integration of advanced elevator control and monitoring systems. This role blends hands-on engineering with team leadership, spanning embedded firmware, industrial communication protocols, hardware integration, and safety-critical compliance. The ideal candidate combines deep technical expertise with the ability to guide multidisciplinary teams from concept through deployment.


Key Responsibilities

System Architecture & Design

  • Lead the design and implementation of elevator motion control algorithms.
  • Architect embedded systems for high-reliability, real-time control applications.
  • Develop and maintain communication interfaces using industrial fieldbus and Ethernet-based protocols.

Firmware Development

  • Write, optimize, and maintain embedded C/C++ firmware for real-time systems such as FreeRTOS.
  • Implement low-level drivers for peripherals such as I²C, SPI, Ethernet, and encoder interfaces.
  • Debug and optimize interrupt-driven state machines and timing-sensitive processes.

Hardware Integration

  • Collaborate on PCB design, ensuring compliance with electrical safety, signal integrity, and manufacturability requirements.
  • Design circuits for sensor integration, power regulation, and ESD/overvoltage protection.
  • Integrate and configure variable frequency drives (VFDs) in velocity and position control modes.

Required Skills & Experience

  • Extensive experience in embedded systems design and software development, including leadership roles.
  • Strong proficiency in C and C++ for embedded applications.
  • Hands-on experience with real-time embedded operating systems and architectures.
  • Expertise in industrial communication protocols (e.g., CANopen, Modbus TCP/IP, BACnet/IP).
  • Experience with safety-critical system design and compliance processes.
  • Familiarity with PCB design tools and electronic circuit best practices.
  • Knowledge of elevator control principles, VFD drive configuration, and motion profiling.
