LTTS vs DornerWorks: overview
LTTS
L&T Technology Services was incorporated in 2012 as a subsidiary of the Larsen & Toubro Group (with engineering heritage tracing back to 2006 as L&T Integrated Engineering Services) and went public via IPO in 2016. Headquartered in Vadodara, India, LTTS reports roughly 23,800 engineers and technologists across 22 global design centers, with embedded systems and semiconductor engineering as one of several business lines alongside automotive engineering, industrial IoT, manufacturing plant engineering, and medical engineering. The scale and public-company governance make LTTS a fit for large enterprise programs, though embedded work competes for attention against several other major practice areas.
DornerWorks
DornerWorks is an embedded systems engineering firm founded in 2000 and headquartered in Grand Rapids, Michigan, serving aerospace, defense, medical, and industrial markets that require high-reliability software, electronics, and FPGA development. Over more than two decades the firm has grown into one of the larger embedded engineering design services firms in the US by team size, without disclosing exact current headcount. DornerWorks' focus on safety- and reliability-critical domains (aerospace, defense, medical) sets it apart from generalist embedded shops, and its FPGA and hypervisor (Xen-based) work is a recognized specialty in the embedded community.
