• Develop and maintain low-level software, device drivers, and middleware for hardware interfaces.
• Integrate and support communication protocols (IEC 61850, DNP3, Modbus, GOOSE messaging, Ethernet).
• Perform software integration, system testing, and validation for protection and control applications.
• Collaborate closely with hardware and power systems engineers for seamless integration of relay logic with hardware platforms.
• Prepare and maintain technical documentation, including software design specifications, test procedures, and compliance reports.
• Ensure adherence to relevant standards (IEC 60255, IEC 61850, cybersecurity guidelines).
• Participate in code reviews and continuous improvement of coding standards and processes.
• Support field issues, diagnostics, and firmware upgrades for deployed products.

Qualifications

• Education: B.E./B.Tech or M.E./M.Tech in Electrical, Electronics, Instrumentation, Computer Engineering, or related fields.
• Experience: 48 years in embedded software development for power systems, protection relays, or substation automation.
