Senior Mixed Signals Engineer

The role

The Senior Mixed Signals Engineer will lead the design and implementation of advanced electronics for satellite and space-based systems. This involves the placement, layout, and high-speed routing of RFSoC-based boards.

What you will do

• Lead the design and implementation of advanced electronics for satellite and space-based systems.
• Perform placement, layout, and high-speed routing of RFSoC-based boards.
• Integrate RF, analog, digital, clocking, power, and high-speed data interfaces into a space-qualified hardware platform.
• Work with RF, electrical, FPGA, and mechanical teams to take hardware from concept through design, prototyping, test, and production.
• Ensure RFSoC layout meets performance, manufacturability, thermal, mechanical, reliability, and space-environment requirements.

Required qualifications

• Bachelor’s degree in Electrical Engineering, Electronics Engineering, or a related discipline.
• 8+ years of experience in mixed-signal, RF, high-speed digital, or advanced PCB design.
• Understanding of electromagnetic principles behind radio frequency communications.
• Ability to interpret PCBA schematics and layout drawings.
• Familiarity with PCB ECAD tools such as Altium for both schematic and layout.
• Demonstrated experience laying out complex RFSoC, FPGA, ADC/DAC, RF, or high-speed mixed-signal boards.
• Strong understanding of mixed-signal PCB design, including controlled impedance, differential signaling, high-speed serial interfaces, clock and synchronization design, power distribution, grounding a
• Hands-on experience using electrical/RF test equipment, including multimeters, oscilloscopes, signal generators, and spectrum analyzers.
• Knowledge of typical performance metrics for RF communications systems.
• Experience using or interpreting results from tools for signal-integrity, power-integrity, electromagnetic, or thermal analysis.
• Experience with RFSoC or comparable devices from AMD/Xilinx, including device pin planning, power requirements, clocking, transceiver interfaces, and high-speed data-converter connectivity.
• Familiarity with interfaces such as JESD204, DDR, PCIe, Ethernet, Aurora, high-speed ADC/DAC interfaces, and RF clocking systems.

Nice to have

• Experience designing electronics for satellites, spacecraft, launch vehicles, avionics, or other mission-critical systems.
• Experience with space-qualified or radiation-tolerant components and PCB materials.
• Familiarity with ECSS, NASA, MIL-STD, IPC, or other relevant aerospace and electronics standards.
• Experience with thermal-vacuum, vibration, shock, radiation, EMC/EMI, and environmental qualification testing.
• Experience designing RF payload, software-defined radio, communications, radar, remote-sensing, or satellite-navigation hardware.
• Knowledge of RFSoC development workflows, including Vivado, PetaLinux, Vitis, RF Data Converter tools, RFDC configuration, and FPGA/embedded integration.
• Experience with RF front-end design, antenna interfaces, frequency conversion, filtering, amplification, and low-noise signal chains.
• Familiarity with radiation analysis, derating, reliability prediction, failure-mode analysis, and fault-tolerant design.
• Experience with Python, MATLAB, or similar tools for design automation, analysis, and test.
• Experience leading technical reviews.
