About the Role

We are looking for a Senior Software Engineer / Technical Lead to design and develop a software gateway that performs protocol translation between Modbus, MQTT, and ZMQ. This gateway will act as a critical bridge between industrial field devices and higher-level IIoT/edge systems, enabling reliable, real-time data exchange in industrial environments.

The ideal candidate is a hands-on systems-level engineer with deep expertise in C/C++, strong understanding of industrial communication protocols, and proven experience building robust, production-grade software for edge computing / IIoT deployments. This role requires both strong individual technical contribution and the ability to lead design decisions for a mission-critical component of our industrial automation stack.

Key Responsibilities
- Design, develop, and maintain a software gateway for protocol translation between Modbus (RTU/TCP), MQTT, and ZMQ.
- Implement and optimize Modbus master/slave communication with field devices (PLCs, sensors, controllers), ensuring reliability and low latency.




- Architect the gateway for performance, fault tolerance, and maintainability in resource-constrained edge environments.
- Develop and maintain the codebase primarily in C/C++, following industry best practices for embedded/systems-level software.
- Containerize the gateway application using Docker for deployment on Linux/Ubuntu-based edge devices.
- Collaborate with cross-functional teams (firmware, cloud, DevOps, QA) to define integration points and data flow across the IIoT stack.
- Establish coding standards, review processes, and technical documentation for the gateway component.
- Troubleshoot and resolve issues related to protocol compatibility, network communication, and device connectivity in field deployments.

Required Skills & Experience
- 10+ years of professional software development experience, with strong command over C and C++ (contemporary C++ preferred).
- Proven experience i
