Develop High-Reliability Embedded Software and Real-Time Systems for Advanced Land Systems and Precision Defense Engineering

Join L&T Precision Engineering & Systems as a Software Engineer within the Design & Development Center (D&DC Land Systems) in Mumbai. In this role, you will design, develop, and integrate mission-critical embedded software, real-time operating system applications, and inter-process communication protocols for complex defense hardware platforms. You will write high-performance C/C++ code, implement built-in diagnostic systems, and perform root-cause analysis on multi-threaded distributed architectures across various serial and fieldbus interfaces.

Key Responsibilities:

  • Design and develop low-level embedded software, drivers, and user interfaces using C, C++, and Qt for Land Systems applications.
  • Develop and debug multi-threaded and multi-process software in real-time operating systems (VxWorks, Linux, QNX).
  • Implement communication protocols over physical layer interfaces including Serial, Ethernet, MIL-STD-1553, CAN, NMEA, and ModBus.
  • Perform system analysis, root-cause diagnostics, and bug fixes for complex distributed systems and on-site operational issues.
  • Design built-in diagnostics and test frameworks to optimize software reliability, system supportability, and scalability.

Tools/Technologies Used:

  • Programming Languages: C, C++, Qt
  • Operating Systems: Linux, VxWorks, QNX (RTOS)
  • Protocols & Fieldbuses: Ethernet, MIL-STD-1553, CAN Bus, Serial (RS-232/485), NMEA, ModBus, IP Protocols, VLANs
  • Architecture & Concepts: Multi-Threading, Multi-Processing, Inter-Process Communication (IPC), Distributed Architectures
  • Development & Debugging Tools: Jira, Hardware-in-the-Loop (HIL) Debuggers, System Diagnostic Tools
