- Define system architecture for SatCom IoT solutions, including payload interfaces, network topology, and device connectivity
- Perform link budget analysis and optimize communication performance for low-power, low-data-rate IoT devices
- Evaluate and select suitable communication protocols (e.g., LoRa, NB-IoT, proprietary waveforms) for satellite integration
- Liaise with frequency licensing and coordination bodies (e.g., ITU, IN-SPACe, WPC) for spectrum allocation, interference mitigation, and regulatory approvals.
- Actively support base terminal design and engineering teams by providing payload specs, simulation models (e.g., STK), and integration guidance.
- Analyse performance metrics like BER, throughput, and latency; optimize for operational resilience.
- Design and optimize waveforms, modulation schemes, and coding techniques for satellite IoT applications
- Collaborate with RF teams on frequency planning, antenna design, and spectrum utilization
- Work with hardware and embedded teams to define IoT terminal/device requirements and interfaces
- Develop and validate network architecture, including gateways, ground stations, and cloud integration
- Conduct trade studies for system performance, scalability, latency, and cost optimization
- Define and manage system-level budgets (link, power, data throughput, latency)
- Support development of protocols for reliable communication, including error correction and retransmission strategies
- Ensure interoperability between satellite systems and terrestrial IoT networks
- Develop concepts of operations (ConOps) for IoT services, including deployment and scaling strategies
- Perform simulations and modeling using tools such as MATLAB/Python and network simulators
- Support system integration, testing, and validation across hardware, RF, and software domains
- Analyze system performance and troubleshoot communication issues during development and testing
- Ensure compliance with regulatory requirements for spectrum, licensing, and satellite communications
- Collaborate with cross-functional teams including systems, RF, software, and mission design
- Prepare and maintain technical documentation, including architecture definitions, design reports, and test results
- Support proposal development, customer interactions, and technical presentations
- Mentor junior engineers and contribute to technical leadership within the team
