Sr. Embedded Engineer

About the role

As a senior embedded systems engineer, you will bring automotive-grade embedded engineering discipline to a greenfield product environment, owning firmware from architecture through production deployment across condition monitoring systems, power electronics, and grid-edge devices. Our integrated model of combining advanced engineering, tight supply-chain control, and exceptional service empowers you to build resilient solutions that restore reliability and control to the operators who keep the world energized.

What you'll do

Design and develop production-grade firmware for asset condition monitoring systems and high-power electronics platforms.

Own schematic review and hardware bring-up i.e. bridging hardware and software from early prototype through field deployment

Drive end-to-end product development cycles including requirements, architecture, implementation, validation, and deployment

Implement and maintain CAN, LIN, Modbus, IEC61850 etc communication stacks as required by system architecture

Apply automotive embedded architecture principles (ISO 26262, AUTOSAR) to power electronics and monitoring applications

Develop FPGA-based control and signal processing pipelines; write low-level peripheral drivers and RTOS application layers

Collaborate with hardware, power electronics, and product teams on system requirements and interface definitions

Participate in design reviews, FMEA, and qualification testing across product lines

Qualifications First Principles Thinking

4+ years of embedded systems engineering experience with at least one complete end-to-end product development cycle

Bachelor's degree in electrical engineering, Computer Engineering, or a related field

Strong proficiency in C/C++; experience with bare-metal, RTOS-based (FreeRTOS, Zephyr), and embedded Linux environments

Hands-on automotive embedded experience: ISO 26262 functional safety, AUTOSAR architecture, or ECU development

Experience with automotive/industrial communication protocols: CAN, LIN, SPI, I2C, UART, Modbus, IEC61850

Proficiency with debugging tools: JTAG, oscilloscopes, logic analysers, and hardware bring-up workflows

Experience with version control (Git), build systems (Make/CMake), and Agile development practices

Strong debugging and problem-solving skills across hardware-software interactions

Excellent written and verbal communications in English
