About the Role

Tata Consultancy Services (TCS), a global IT and consulting leader with over 616,000 professionals worldwide, is seeking a dedicated VSAT L2 Engineer / Satellite Communication Specialist based in Doha, Qatar. This full-time position involves working remotely to support and enhance satellite communication systems integral to TCS’s technological services.

Key Responsibilities

Conduct in-depth troubleshooting and fault isolation for issues such as VSAT link failures, low SNR or high BER conditions, hub-to-remote communication disruptions, and network congestion affecting satellite link performance.
Diagnose root causes including alignment discrepancies, radio frequency interference, hardware malfunctions involving modems, antennas, and RF components, as well as weather-induced impairments.
Manage and resolve priority incidents (P1/P2) escalated from Level 1 support, ensuring service restoration within defined mean time to repair (MTTR) objectives.
Collaborate with field technicians for antenna realignment, coordinate with Network Operations Center teams for configuration updates, and engage vendors or original equipment manufacturers to facilitate issue resolution.
Analyze RF and satellite parameters such as link budgets, carrier performance metrics, uplink/downlink integrity, and troubleshoot environmental influences like rain fade and atmospheric effects as well as technical variables such as power imbalances and frequency interference.
Perform thorough root cause analysis for persistent link failures and recurring VSAT downtime; recommend corrective actions and preventative measures following CAPA practices.
Support change management activities including VSAT installation, system migration, hub upgrades, configuration adjustments, and conduct pre-implementation checks plus post-deployment validations assessing risks and impacts.
Coordinate with OEMs (including Hughes, Gilat, iDirect), field service teams, and satellite service providers; manage technical assistance center and vendor escalations effectively.
Monitor link stability, maximize throughput, maintain uptime, and address congestion and RF inefficiencies to optimize satellite network performance.
Provide technical mentorship and guidance to Level 1 support personnel, review escalated issues to improve troubleshooting effectiveness, and enhance operational procedures and knowledge repositories.
Prepare detailed reports encompassing root cause analyses, performance metrics, and incident reviews; actively participate in problem management and service improvement initiatives.

Required Skills and Knowledge

Extensive expertise with VSAT systems including hub, remote terminals, and satellite links.
Strong understanding of RF principles such as signal-to-noise ratio (SNR), bit error rate (BER), energy per bit to noise power spectral density ratio (Eb/N0), and power level management.
Comprehensive knowledge of satellite communication theory and practical applications.
Basic familiarity with IP networking fundamentals and routing concepts.
Hands-on experience operating VSAT platforms from major vendors like Hughes, iDirect, and Gilat as well as using monitoring and diagnostic tools specific to satellite communications.
