LAYIQ - Principal Hardware Engineer, Analog & RF at Mesa Quantum Systems

10+ years of board-level analog and RF hardware design, including at least one product taken from prototype through volume production
A track record of multi-layer boards you personally designed and laid out, mixing sensitive analog, RF, and digital circuits: stack-up definition, controlled impedance, grounding and return-path control, shielding, and thermal management. Be ready to walk us through one in the interview.
Current, hands-on proficiency in a professional PCB design tool such as Altium Designer, Cadence Allegro/OrCAD, or KiCad
Deep expertise in low-noise precision analog: signal conditioning, low-noise amplifiers, ADC and DAC interfacing, and rigorous noise budgeting
RF circuit design through GHz frequencies, with hands-on experience in low phase noise frequency synthesis, PLLs, and VCOs
Strong SPICE simulation and circuit analysis skills, including noise, stability, and tolerance analysis
Hands-on bench proficiency with oscilloscopes, spectrum and phase noise analyzers, network analyzers, source measure units, and signal generators
Scripting experience for instrument control, characterization, and data analysis
Version control (Git or similar) for hardware design files
Strongly Preferred
Chip-scale atomic clocks, rubidium or cesium oscillators, OCXOs, or other precision frequency references
Optoelectronics: VCSEL or laser diode drive, photodetector readout, laser frequency locking
Embedded firmware in C/C++ on ARM Cortex-M class microcontrollers
FPGA development in Verilog or SystemVerilog, including real-time DSP (lock-in detection, PID, digital filtering)
Hardware design under hard size, weight, and power budgets
Board-level integration of custom mixed-signal silicon, including block specification or characterization
Hands-on management of PCB fabricators, assembly houses, and contract manufacturers
Defense, aerospace, or space-qualified hardware experience
Familiarity with atomic physics or other quantum sensing modalities
Experience leading or mentoring a small hardware team
Eligibility
Due to U.S. Department of Defense funding requirements, applicants must be U.S. persons (U.S. citizens or lawful permanent residents). The ability to obtain and maintain a U.S. security clearance may be required for certain projects.
