Telecom infrastructure: wireless, optical, and packet networks for carriers and ISPs

Telecommunications Bangalore, Karnataka 1,001–5,000 employees Founded 2000 Public Company

Tejas Networks manufactures end-to-end broadband and optical networking products for telecom operators across 75+ countries, with 900,000+ systems deployed at 99.999% uptime. The stack spans 4G/5G (3GPP, O-RAN), DWDM, GPON, IP/MPLS, and satellite-IoT, backed by a C/C++, Python, and Kubernetes foundation. Over 60% of headcount is R&D-focused, and current hiring (57 engineering roles in 30 days) skews heavily toward wireless and cloud-native work—5G drivers, NFV/SDN integration, and test automation—signaling a pivot toward software-defined and virtualized network architecture.
