Job Description

As a Lead Engineer at Tejas Networks, you will drive the validation and automation strategy for our high-performance routing portfolio. You will serve as the technical lead for modern transport technologies, specifically focusing on the transition from legacy MPLS to Segment Routing (SR-MPLS) and SRv6. This role requires a leader who can design complex network topologies, automate them using Python, and perform deep-dive analysis into protocol-level failures.

Responsibilities

Protocol Leadership: Lead the test strategy for next-generation routing features, with a primary focus on Segment Routing (SR) and SRv6 (Segment Routing over IPv6).
Automation Architecture: Design and optimize Python-based automation frameworks to validate SR/SRv6 policies, TI-LFA (Topology-Independent Loop-Free Alternate), and network slicing.
Test Lifecycle Management: Create, execute, and manage high-scale test plans for L2/L3 protocols including BGP, OSPF, IS-IS, and MPLS.
Failure Analysis & Debugging: Take ownership of analyzing complex failures. Use your expertise to perform root-cause analysis (RCA) by investigating system logs, FIB/LFIB tables, and packet captures.
Performance & Scale: Conduct high-scale stress testing using IXIA/Spirent to validate the control plane and data plane performance of SRv6 endpoints.
Mentorship: Guide junior engineers in developing robust test cases and high-quality Python code.

Qualifications

7+ years of experience in Networking Domain testing with a focus on L2/L3 Routing.

Protocol Mastery:

Advanced L3: Deep knowledge of OSPF, IS-IS, and BGP (specifically extensions for Segment Routing).
Segment Routing: In-depth understanding of SR-MPLS and SRv6 architectures, including SIDs (uSID), LFA/TI-LFA, and Traffic Engineering (SR-TE).
L2 Mastery: Strong experience with VLANs, xSTP, and L2VPN/EVPN.

Expert Python Automation: 7+ years of experience writing production-grade Python scripts for network automation (e.g., PyTest, Netmiko, or Scapy).
Hardware Tools: Expert-level proficiency with IXIA (IxNetwork) or Spirent for simulating SRv6 traffic and validating scale.
Analysis Tools: Mastery of Wireshark for decoding SRH (Segment Routing Header) and other protocol extensions.

About The Team

Tejas Networks is driving cutting-edge research to revolutionize content delivery and wireless communication technologies. One major area of focus is the development of advanced solutions that integrate broadcast and cellular networks to enable seamless content distribution. These innovations aim to alleviate network congestion, reduce infrastructure costs, and enhance the overall user experience. A key outcome of this work is a next-generation Content Delivery Network (CDN) architecture that supports Direct-to-Mobile (D2M) delivery, developed in collaboration with leading CDN and content providers. This initiative is backed by a robust portfolio of patented technologies in broadcast and content delivery systems.

In parallel, significant efforts are being made to enhance the flexibility and efficiency of wireless network operations. Research in this domain includes the creation of a domain-specific language (DSL) that enables platform-independent expression of Radio Access Network (RAN) functions, helping reduce dependency on proprietary hardware. Additionally, advanced AI/ML techniques are being employed to automate network management, streamline operations, and optimize resource utilization—resulting in substantial cost savings and improved performance. These contributions have led to multiple patents and active participation in international standardization efforts.
