Description

• As a Senior Software Engineer specializing in C++ and Golang, you will play a pivotal role in developing southbound connectors for communication with PLCs and industrial control systems, enabling seamless data exchange between our Litmus Edge Products and a diverse range of IIoT devices, industrial protocols, and operational technology systems.

• Your primary responsibility will be to design, implement, and maintain robust connectors that ensure the reliability, security, and efficiency of communication between our software and the operational technology (OT) layer. Your work will be essential in enabling our products to scale and adapt to ever-evolving industrial environments.

What you will do:

1. Develop C++ and Golang-based southbound connectors that communicate directly with PLCs and industrial control systems using protocols such as OPC-UA, Modbus, EtherNet/IP, PROFINET, and DNP3.

1. Implement support for IIoT protocols such as MQTT, CoAP, and SOAP, enabling effective communication with industrial devices and sensors.

1. Build connectors for streaming protocols such as WebSockets and HTTP/2, enabling real-time data streaming and communication with external systems.

1. Implement robust error handling and fault-tolerance mechanisms to ensure connectors are resilient to failures in OT environments, delivering a seamless user experience.

1. Collaborate with cross-functional teams — including product managers, OT/controls engineers, and other developers — to understand requirements and deliver high-quality integration solutions.

1. Conduct thorough testing, including unit tests, integration tests, and hardware-in-the-loop tests, to validate the functionality and performance of southbound connectors.

1. Optimize code and apply best practices to enhance connector performance, latency, and scalability.

1. Provide clear and comprehensive technical documentation for all connectors and APIs, enabling seamless adoption by other team members and customers.

1. Monitor connector performance, track metrics, and implement logging practices to troubleshoot and resolve issues efficiently.

1. Stay current with advancements in the C++, Golang, and industrial automation ecosystems, continuously developing your skills and knowledge.

1. Contribute to the development of our open-source projects, sharing expertise with the wider developer community.

What you will bring:

1. Bachelor's or Master's degree in Computer Science, Software Engineering, Electrical Engineering, or a related field.

1. Proven experience as a Software Engineer with a minimum of 5+ years of relevant work experience.

1. Strong proficiency in C++ with Golang experience highly desirable.

1. Demonstrated experience developing southbound connectors for PLCs and industrial control systems, with hands-on knowledge of industrial protocols such as OPC-UA, Modbus, EtherNet/IP, or PROFINET.

1. Deep understanding of networking concepts, real-time communication, and industrial automation environments.

1. Experience implementing support for IIoT protocols is highly desirable.

1. Solid working knowledge of data serialization, error handling, and security principles in integration projects — 5+ years of experience preferred.

1. 5+ years of experience with version control systems (e.g., Git) and collaborative development practices.

1. Excellent problem-solving skills and the ability to analyze complex integration challenges in OT environments.

1. Strong communication skills and the ability to work collaboratively with cross-functional teams including engineers from both software and industrial automation backgrounds.

If you are a motivated, innovative, and results-oriented engineer with a passion for bridging the gap between industrial control systems and modern edge computing infrastructure, we encourage you to apply. Join our dynamic team and play a crucial role in shaping the future of Litmus Automation as a leading player in the Industrial Internet of Things space..
