Radio Frequency Design Engineer

Role Overview and Responsibilities

Dhruva Space is looking for an experienced RF Design Engineer SDR Hardware to join our engineering team. This role is ideal for a professional with strong expertise in SDR hardware design, including schematics, PCB layout, RF front-end circuitry, and board bring-up/debugging. The candidate will play a critical role in developing baseband and RF front-end modules to enable reliable, high-performance SDR systems for advanced communication applications.

Key responsibilities include, but are not limited to:

• Design schematics and multi-layer PCB layouts for SDR baseband and RF boards.
• Develop baseband hardware using Xilinx RFSoC platforms with high-speed ADCs/DACs or other advanced RF transceivers.
• Design and integrate RF front-end circuits, including LNAs, PAs, filters, baluns, duplexers, and matching networks.
• Apply best practices in signal integrity, power integrity, and EMI/EMC compliance for board design and conduct EMI/EMC testing.
• Conduct board bring-up, debugging, and validation using advanced test equipment (oscilloscopes, spectrum analyzers, VNAs, power meters).
• Collaborate with FPGA/DSP teams for end-to-end system integration of baseband and RF modules.
• Perform component selection, simulations, and design verification.
• Interface with fabrication vendors to ensure manufacturability and DFM compliance.

Candidate Requirements:

• Bachelors/Masters degree in Electronics, Electrical Engineering, or related field.
• 3+ years of experience in schematic capture and PCB layout for SDR and RF hardware.
• Strong background in Zynq SoC-based designs and Xilinx RFSoC platforms with integrated high-speed ADC/DACs.
• Proficiency in working with high-speed RF transceivers for SDR applications.
• Solid expertise in RF front-end design (LNAs, PAs, filters, switches, duplexers, impedance matching).
• Hands-on experience with PCB design tools (Altium Designer, Cadence Allegro, OrCAD).
• Knowledge of high-speed digital design (DDR3/DDR4, SERDES, JESD204B/C, LVDS, Gigabit Ethernet).
• Proven experience in board bring-up, debugging, and hardware-level testing using advanced RF/mixed-signal equipment.
• Familiarity with SDR concepts, modulation techniques, and tools such as GNU Radio, MATLAB/Simulink, and Vivado.
• Additional experience in satellite communication SDRs, thermal/low-power design, ruggedized electronics, and DFx practices (DFM/DFT).
