Software Engineer & GenAI Trainee

LTTS interviews typically consist of an online aptitude test followed by a technical round focusing on C/C++ coding, OS concepts, and embedded system scenarios. The difficulty is moderate to high, with emphasis on problem‑solving speed and clear explanation. The HR round assesses communication skills, teamwork attitude, and cultural fit. Preparing with mock coding tests and revising core embedded concepts helps candidates perform well.

LTTS promotes a performance‑driven culture where engineers are encouraged to experiment, learn and take ownership of their projects. The organization offers structured career ladders, regular training programs, and a healthy work‑life balance with flexible timings for offshore collaborations.

Graduates of B.E/B.Tech, M.E/M.Tech, BCA, MCA or B.Sc (any branch) from the 2023, 2024, 2025 or 2026 batches. Minimum aggregate of 60% (or CGPA 6.0/10). Maximum of 2 active backlogs allowed at the time of application. Candidates must have a valid passport for potential travel to client sites. No age limit specified, but typically candidates should be under 28 years.

L&T Technology Services (LTTS) is the engineering services subsidiary of the L&T Group, a global conglomerate with a legacy of more than 80 years in infrastructure, construction, and technology. LTTS focuses on digital engineering and the Internet of Things, delivering high‑end solutions to aerospace, defence, automotive, telecom, and industrial sectors. The company operates across the globe with development centres in India, the US, Europe and Asia, and is known for its strong emphasis on research, innovation and a culture that nurtures technical excellence. The role of Software Engineer & GenAI Trainee is designed for recent graduates and early‑career professionals (0‑2 years of experience) who are passionate about embedded systems, distributed software architectures, and the emerging field of generative AI. As a part of the LTTS engineering team, you will work on cutting‑edge land systems projects that involve real‑time operating systems such as Linux, VxWorks and QNX, and communication stacks ranging from CAN and ModBus to Ethernet and NMEA. The position offers a unique blend of traditional embedded software development and exposure to AI‑driven modules, giving you a holistic view of modern defence and industrial software. Key responsibilities include: 1. Design, develop, and maintain high‑performance C/C++ code for embedded platforms. 2. Build and debug applications on Linux, VxWorks, and QNX operating systems. 3. Create and enhance diagnostic and debugging tools to improve system reliability. 4. Implement multi‑threaded and multi‑process solutions, handling synchronization and inter‑process communication. 5. Participate in root‑cause analysis and issue‑fixing for field‑reported bugs. 6. Contribute to the development of distributed architecture components and communication protocols such as CAN, Ethernet, ModBus, Serial, NMEA, and 1553. 7. Analyse system scalability and performance metrics, proposing optimisations where needed. 8. Collaborate with cross‑functional teams to integrate GenAI modules that assist in predictive maintenance and autonomous decision‑making. 9. Document code, test procedures, and system designs following industry standards. 10. Support verification and validation activities to ensure compliance with defence and safety regulations. The technical stack primarily revolves around C/C++, real‑time operating systems, POSIX threads, IPC mechanisms, and communication protocol stacks. Familiarity with Jira for task management, Git for version control, and basic networking concepts (IP, VLANs, Ethernet switching) is also valuable. Preferred candidates will have exposure to large‑scale software systems, strong analytical abilities, and good communication skills. Growth at LTTS is structured and merit‑based. Fresh engineers typically start as Software Engineers, progress to Senior Engineer, then to Lead Engineer or Technical Architect, with opportunities to move into specialised AI or systems integration roles. The company encourages continuous learning through internal MOOCs, certifications, and participation in global projects, making it an ideal place to build a long‑term career in both embedded systems and AI. Why join LTTS? Apart from competitive compensation, you get to work on mission‑critical projects for defence and industrial giants, gain hands‑on experience with a variety of operating systems and protocols, and be part of a forward‑looking AI initiative that will shape the future of autonomous systems. The collaborative environment, mentorship from senior technologists, and exposure to global clients make LTTS a compelling choice for ambitious engineers.
