Software Engineer

This role sits at the intersection of backend engineering and real-world hardware integration. We are seeking a highly skilled Software Developer with strong expertise in .NET development, multi-threaded systems, and socket programming, along with hands-on experience interfacing with hardware devices and industrial communication protocols.

This role involves developing real-time control and monitoring applications that interface with sensors, controllers, and industrial equipment using protocols such as SAE J1939, NMEA 2000, and Modbus.

The ideal candidate is comfortable working close to hardware, debugging low-level communication issues, and building robust, high-performance software for mission-critical systems.

This is not purely web development - it involves systems thinking, reliability, and performance in safety-critical environments.
