Software Engineer

The interview process typically starts with a timed online aptitude test focusing on logical reasoning, quantitative aptitude, and basic English. Successful candidates move to a technical interview where they are assessed on C/C++ coding, real‑time operating system concepts, and embedded communication protocols. The final HR round evaluates cultural fit, communication skills, and career aspirations. Candidates report a moderate difficulty level with a strong emphasis on problem‑solving and practical knowledge.

D&DC Land Systems promotes a collaborative environment where engineers are encouraged to innovate and take ownership of their projects.

Round 1: Online aptitude test (logical reasoning, quantitative, verbal) → Round 2: Technical interview (programming, OS concepts, embedded systems) → Round 3: HR interview (fitment, communication, career goals)

L&T Group, one of India’s largest engineering conglomerates, operates across infrastructure, technology, and defense sectors. Within this ecosystem, D&DC Land Systems focuses on designing and delivering advanced land‑based platforms for defense and aerospace customers. The division leverages cutting‑edge embedded software, real‑time operating systems, and robust communication protocols to build mission‑critical solutions that operate in harsh environments. Working at D&DC Land Systems means being part of a high‑impact team that contributes to national security projects while enjoying the stability and growth opportunities of a multinational corporation. As a Software Engineer in the D&DC Land Systems team, you will be responsible for developing, testing, and maintaining embedded software for distributed architecture systems. You will work closely with hardware engineers, system architects, and senior developers to translate complex requirements into reliable code that runs on real‑time operating systems such as VxWorks, QNX, and Linux. The role offers exposure to a wide range of communication interfaces—Serial, Ethernet, CAN, ModBus, and MIL‑STD‑1553—making it an ideal launchpad for fresh engineers eager to master embedded and systems programming. Key responsibilities include: 1. Write clean, efficient C/C++ code for real‑time applications. 2. Develop multi‑threaded and multi‑process modules adhering to OS principles. 3. Implement inter‑process communication mechanisms and IPC debugging tools. 4. Design and integrate diagnostics and test code to improve system reliability. 5. Participate in root‑cause analysis of field issues and provide timely fixes. 6. Collaborate with cross‑functional teams to define software architecture and communication protocols. 7. Create and maintain documentation, test plans, and release notes. 8. Contribute to continuous improvement of development workflows using tools like Jira. 9. Optimize software for scalability and performance across distributed nodes. 10. Support customers during integration and post‑deployment phases. The tech stack revolves around C, C++, Linux, VxWorks, QNX, Qt, and a suite of communication standards (Ethernet, VLANs, IP, CAN, ModBus). You will also gain hands‑on experience with version control, CI/CD pipelines, and debugging environments. Growth path: Starting as an Associate Engineer, you can progress to Senior Engineer, Lead Engineer, and eventually Architecture or Project Management roles, depending on performance and interest. The organization encourages continuous learning through internal training, certifications, and exposure to cutting‑edge defense projects. Why join? You will work on mission‑critical systems that have a direct impact on national defense, receive mentorship from seasoned engineers, and enjoy a competitive compensation package with clear career progression. The collaborative culture, emphasis on technical excellence, and access to state‑of‑the‑art tools make D&DC Land Systems an attractive destination for ambitious fresh graduates.
