About the role
Senior Mixed-Signal Engineer responsible for the placement, layout, and high-speed routing of RFSoC-based boards for satellite/space systems, coordinating with RF, FPGA, mechanical teams from concept to production.
Responsibilities
- Lead the design and implementation of advanced electronics for satellite and space-based systems.
- Placement, layout, and high-speed routing of RFSoC-based boards with integration of RF, analog, digital, clocking, power, and high-speed data interfaces into a space-qualified hardware platform.
- Collaborate with RF, electrical, FPGA, and mechanical teams to take RFSoC hardware from concept through design, prototyping, test, and production.
- Ensure RFSoC layout meets performance, manufacturability, thermal, mechanical, reliability, and space-environment requirements.
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 (controlled impedance, differential signaling, high-speed serial interfaces, clock and synchronization design, power distribution, grounding/shielding, RF transmission lines, signal/power integrity).
- Hands-on experience with electrical/RF test equipment (multimeters, oscilloscopes, signal generators, spectrum analyzers).
- Knowledge of performance metrics for RF communications systems.
- Experience with signal-integrity, power-integrity, electromagnetic, or thermal analysis tools.
- 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, RF clocking systems.
- Willingness to travel for off-site testing as needed.
- Self-starter with proactive design-to-implementation mindset.
- Strong problem-solving, attention to detail, and ability to thrive in fast-paced, cross-team environments.
- Effective communication and interpersonal skills for collaboration with multidisciplinary teams and external partners.
- Understanding of manufacturing constraints, PCB fabrication, assembly, inspection, and design-for-manufacturing.
