Senior Embedded Software Engineer

Senior Embedded Systems & Software Engineer – Elevator Control Systems

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.

HMI & Monitoring Systems

• Oversee development of elevator HMIs using commercial HMI software platforms and custom solutions.
• Maintain and modernize legacy monitoring clients, transitioning from desktop-based to modern web-based interfaces.
• Optimize data visualization and reporting features for maintenance and traffic analysis.

Compliance & Safety

• Ensure designs meet applicable elevator safety standards and regulatory requirements.
• Implement redundant safety monitoring and fault handling
• Work with absolute positioning systems (APS) and safety-rated devices for compliance.

Leadership & Collaboration

• Supervise and mentor a small team of software engineers.
• Coordinate with mechanical, electrical, and manufacturing teams to ensure design compatibility.
• Interface with vendors, contractors, and certification agencies to validate product readiness.

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.

Work Environment

• Combination of office, lab, and field work in elevator equipment rooms and test facilities.
• Collaborative, hands-on, and iterative design process with emphasis on reliability, maintainability, and safety.
