About the Role
We are building the next-generation Global Satellite Constellation for highly exact and secure Positioning, Navigation, and Timing (PNT) using Low Earth Orbit (LEO) satellites. We are seeking an RF & Communications Engineer to lead the development of Inter-Satellite Link (ISL). The role involves development of RF communication architectures, modem design, synchronization techniques, link performance analysis, etc. for space-based ISL.
Key Responsibilities
Design, simulate and analyse RF ISL architectures under realistic orbital conditions for LEO satellites.
Develop communication waveforms, modulation and coding schemes for satellite crosslinks.
Perform RF link budget analysis for inter-satellite communication scenarios.
Design synchronization, acquisition and tracking algorithms for ISL terminals.
Work on Doppler compensation and carrier/frequency synchronization for high-dynamics LEO environments.




Develop ranging and time-transfer techniques using RF crosslink signals.
Support design improvements and component selection for hardware realisation of ISL.
Evaluate spectrum allocation, interference and coexistence considerations for ISL operation.
Support hardware integration, laboratory testing and realtime ground and space testing.
Collaborate with other subsystems like navigation, timing, mission planning etc. during the entire ISL development.
Required Skills & Experience
Master’s or PhD in Electronics and Communications Engineering, related field.
Strong understanding of RF and digital communication systems including modulation, coding, synchronization and wireless link design.
Experience with RF system analysis, link budget calculations and communication system simulations using tools.
Knowledge of satellite communication systems, orbital dynamics effects on communication links and Doppler compensation techniques for high-dynamics environments
