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

What we offer

• Collaborative work environment
• Challenging problems to solve
• Competitive benefits including medical, dental, and vision
• Equity package
