L&T Technology Services (LTTS)

L&T Technology Services (LTTS) was carved out of Larsen & Toubro’s engineering-services operations and listed separately in 2016, building on decades of L&T’s engineering, procurement and construction (EPC) and product-engineering heritage. LTTS specialises in engineering research and development (ER&D) services, a category distinct from traditional IT outsourcing that focuses on designing and engineering physical products, embedded software and industrial systems for global clients across automotive, aerospace, industrial products, medical devices, telecom and process industries. Its IoT and Industry 4.0 practice helps manufacturers embed connectivity and sensing into physical products, build industrial IoT platforms for factory monitoring, and modernise legacy plant equipment with retrofit sensor and connectivity kits. LTTS has established dedicated Industry 4.0 and smart-manufacturing innovation centres to showcase end-to-end capability, from PLC programming and edge-device firmware through to cloud analytics dashboards, reflecting the full stack an industrial IoT retrofit project typically requires. Because ER&D work tends to be deeply technical and product-specific, LTTS’s client relationships often run for years across a single product line’s lifecycle. For an India-focused IoT news audience, LTTS is a key example of how India’s engineering-services sector has moved beyond IT outsourcing into higher-value embedded and industrial IoT engineering work for global manufacturers.
