• Implement and maintain communication protocols, including:
• Modbus/TCP
• Serial communications (RS232 / RS422 / RS485)
• Ethernet (UDP/TCP)
• Integrate firmware with industrial sensors and actuators using ADCs/DACs.
• Develop and maintain test frameworks, including:
• Unit testing
• Static analysis
• Code coverage
• Hardware-in-the-loop (HIL) and Software-in-the-loop (SIL) testing
• Participate in code reviews and quality assurance processes to maintain safety and reliability.
• Produce and maintain technical documentation, including specifications, design diagrams, test plans, and release notes.
• Contribute to trunk-based development workflows, using Git and Semantic Versioning.
• Support manufacturing, commissioning, testing, and service teams in diagnosing and resolving software issues.
• Contribute to the continuous improvement of development processes, tools, and engineering standards.
