• Develops firmware in C, C++, and assembly with a focus on efficiency, maintainability, and adherence to coding standards.
• Collaborates with Power Electronics, Hardware, Systems, and Validation teams to define control architectures, hardware/firmware interfaces, and system‑level requirements.
• Integrates internal and third‑party software modules and performs system‑level integration testing.
• Debugs embedded software on target hardware using debuggers, emulators, and lab instrumentation.
• Analyzes and interprets test results to verify performance and ensure product reliability.
• Produces clear and comprehensive technical documentation including requirements, design specifications, and technical reports.
• Supports engineering processes including version control, defect tracking, change control, and compliance with development workflows.
• Provides progress updates, identifies risks, and delivers effort and feasibility assessments for assigned work packages.
• Mentors and coaches other firmware engineers, contributing to technical capability development within the team.
• Performs other duties supporting engineering and organizational objectives as required.

• Degree in Computer Engineering, Electrical/Electronic Engineering, Computer Science, Mechatronics, or a related discipline.
• At least 10+ years of professional embedded software development experience, with expert proficiency in C and proven experience in digital control and DSP‑based embedded systems.
• Hands‑on experience developing and tuning digital control algorithms for power electronics applications.
• Strong understanding of power converter topologies (AC/DC, PFC, DC/DC, DC/AC, resonant converters) and control principles.
• Knowledge and practical experience with RTOS‑based embedded systems (e.g., FreeRTOS, Zephyr).
• Ability to read and interpret schematics, datasheets, and hardware documentation.
• Proficient in using lab equipment such as oscilloscopes, logic analyzers, DMMs, and data acquisition tools.
• Experience with software testing methodologies and the use of automation or third‑party test tools.
• Experience with configuration management, defect tracking, and change control systems.
• Strong analytical, debugging, and problem‑solving skills.
• Consistently exhibit and model Delta‑Q values (Collaboration, Perseverance, Innovation, Driving Results).

• Experience with scripting languages (e.g., Python, Bash) for automation, testing, and tooling.
• Strong understanding of communication protocols such as UART, SPI, I2C, CAN, J1939, Modbus, and Ethernet.
• Knowledge of AC/DC power systems or power electronics.
• Exposure to CI/CD pipelines, build automation, and automated test frameworks.
• Familiarity with tools such as JIRA, Confluence, and Microsoft Office Suite.
• Understanding of low‑power design strategies and energy‑efficient firmware techniques.
• Experience with safety‑critical or regulatory‑compliant firmware development (e.g., ISO 26262, IEC 61508).
