Technical Lead

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++ (modern C++ preferred).
• Proven experience in edge computing or Industrial IoT (IIoT) application development.
• Hands-on experience implementing or integrating Modbus (RTU and/or TCP) communication — this is a critical requirement.
• Working knowledge of MQTT and ZMQ (ZeroMQ) messaging protocols and their use in distributed/edge architectures.
• Strong experience developing and deploying applications on Linux/Ubuntu environments.
• Practical experience with containerization technologies (Docker) for building and deploying edge applications.
• Solid understanding of networking fundamentals, multi-threading, and real-time/low-latency system design.
• Strong debugging, performance tuning, and problem-solving skills in production environments.
