Hiring _Tech Lead SW Dev / Architect (C++/Linux)_Chennai Location_ Attractive CTC
Key Responsibilities
In this role, you will design, implement, and maintain a high-performance, multi-threaded C++ application running on Linux (NixOS), ensuring the code is clean, testable, and maintainable for long-term scalability. You will be responsible for integrating the application with Siemens PLC systems, optimizing communication protocols like PROFINET or Modbus to enable seamless system operations. A key aspect of your work will involve contributing to cloud integration features for data offloading and centralized management. You will also focus on addressing performance bottlenecks in real-time applications while ensuring the software aligns with the broader system-of-systems architecture. Collaboration is critical in this role; you will work closely with cross-functional teams, including hardware engineers and operations specialists, to deliver robust, well-integrated solutions. Taking ownership of backlog tasks, you will drive them to completion independently, maintaining high-quality standards and meeting deadlines. Your ability to approach complex challenges with a system-level perspective and a collaborative mindset will be central to your success in this position. Must-Have Skills
