Hyderabad, India Dhruva Space Full time

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 RFSo C 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: Bachelor’s/Master’s 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 So C-based designs and Xilinx RFSo C 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, Or CAD). Knowledge of high-speed digital design (DDR3/DDR4, SERDES, JESD204 B/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).
