Job description

Skynetics Pvt. Ltd. is looking for a skilled and passionate RF Design Engineer to join our R&D team and contribute to the design and development of advanced Electronic Warfare (EW), RF, and defence and aerospace systems. The role offers hands-on experience in developing high-performance RF hardware, from circuit design and PCB development to prototyping, testing, and system integration.

Key Responsibilities

• RF Circuit and Subsystem Design: Design, develop, simulate, and validate RF circuits and subsystems, including schematics, component selection, and PCB implementation.
• Electronic Warfare (EW) Systems: Contribute to RF hardware development for electronic warfare, signal intelligence, jamming, anti-jamming, and other defence applications.
• RF Data Converters: Work with high-speed RF ADCs and DACs, including interface integration, clocking, sampling considerations, and signal-chain design.
• RFSoC-Based Systems: Support the development and integration of Xilinx/AMD UltraScale+ RFSoC-based platforms for advanced RF signal processing and software-defined radio applications.
• Software-Defined Radios (SDRs): Develop and integrate RF front ends and hardware for SDR platforms, including transmit and receive chains.
• Frequency Synthesis and Conversion: Design and integrate frequency synthesizers, PLLs, local oscillators, frequency upconverters, and downconverters.
• Power Amplifiers: Design, evaluate, and integrate RF power amplifiers, including impedance matching, gain, output power, linearity, and thermal considerations.
• RF PCB Design: Support RF PCB layout, impedance-controlled routing, grounding, shielding, stack-up selection, and high-frequency layout best practices.
• Testing and Debugging: Perform RF bring-up, troubleshooting, characterization, and system-level integration using laboratory instruments.
• Documentation: Prepare test reports, performance analyses, design documentation, and validation reports.

Required Skills

• Strong understanding of RF and microwave engineering fundamentals, including impedance matching, S-parameters, transmission lines, filters, amplifiers, and oscillators.
• Hands-on experience with RF testing, measurement, debugging, and troubleshooting.
• Familiarity with RF laboratory equipment such as Vector Network Analyzers (VNAs), spectrum analyzers, signal generators, oscilloscopes, and power meters.
• Understanding of RF transmit/receive chains, frequency conversion, and RF front-end architectures.
• Knowledge of PCB design principles, including grounding, impedance control, and RF signal integrity.
• Ability to analyse circuit performance, interpret measurement results, and troubleshoot hardware independently.
• EMI/EMC: Electromagnetic compatibility, interference mitigation, shielding, and compliance testing.
• Defence, Aerospace, and Satellite Communications: Experience with high-reliability RF hardware, satellite communication systems, or mission-critical electronics.

Preferred / Additional Skills

Experience or exposure in one or more of the following areas will be an advantage:

• Electronic Warfare (EW): RF jammers, anti-jamming systems, wideband receivers, signal intelligence, and RF threat simulation.
• High-Speed Data Converters: RF ADCs, DACs, JESD204B/JESD204C interfaces, sampling clocks, and data-converter evaluation platforms.
• RFSoCs and FPGA-Based Systems: AMD/Xilinx UltraScale+ RFSoCs, FPGA-based digital signal processing, and RF data acquisition and generation.
• Software-Defined Radio (SDR): SDR architectures, digital upconversion/downconversion, and RF signal processing.
• Frequency Synthesis: PLLs, VCOs, synthesizers, phase noise, spurious performance, and frequency-hopping architectures.
• RF Conversion Chains: Mixers, upconverters, downconverters, local oscillators, and intermediate-frequency (IF) stages.
• RF Power Amplifiers: Solid-state power amplifiers, driver amplifiers, gain stages, output matching, and linearity optimisation.
• RF Simulation Tools: Keysight ADS, Cadence AWR, Ansys HFSS, CST Studio Suite, or equivalent tools.
• Antenna Engineering: Antenna design, simulation, matching, and measurement.
