About the Role

Design mixed-signal electronics for space applications, including high-speed ADC/DAC chains, amplifiers, driver circuits, and FPGA interfaces. Ensure optimal performance in space terminals and ground station receivers where signal integrity is critical.

Responsibilities

• Design schematic and PCB layouts for mixed-signal boards: high-speed data converters, transimpedance amplifiers, laser/modulator drivers, low-noise bias supplies, and clocking.
• Perform signal integrity and power integrity analysis for multi-GHz analog paths and high-speed serial links (JESD204, SerDes).
• Develop precision analog control loops: laser temperature/current control, photodiode bias, FSM drive electronics, and AGC chains.
• Bring up, debug, and characterize boards in the lab; own noise, linearity, and bandwidth verification against link budget allocations.
• Define and implement FPGA interfaces to data converters and control peripherals; collaborate on (or implement) RTL for data capture, calibration, and real-time control.
• Design for reliability and environment: derating, worst-case analysis, and parts selection for space applications (rad-tolerant/rad-hard component trades).
• Support EMC/EMI design and testing, and environmental qualification campaigns.

Requirements

• BS/MS in Electrical Engineering or related field.
• 4+ years of mixed-signal hardware design experience, including high-speed PCB design (Altium, Cadence Allegro, or similar).
• Strong analog fundamentals: noise analysis, op-amp and TIA design, PLLs/clocking, power supply design.
• Hands-on lab experience with oscilloscopes, spectrum/network analyzers, and automated board characterization.
• Experience interfacing data converters to FPGAs.
• Familiarity with space-grade electronics design: radiation effects (TID, SEE), redundancy, and derating standards (ECSS or NASA EEE-INST-002).
• Experience with low-jitter clock distribution and time-transfer systems.
• Must be a U.S. citizen or national, U.S. lawful permanent resident, protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain required U.S. Department of State authorizations.

About the Company

• Azora is building high-bandwidth communications infrastructure for environments where fiber can’t reach.
• This work spans LEO spacecraft constellations, lunar exploration missions, GEO satcom, deployable optical ground for defense, and data centers both on- and off-world.
• Azora is developing compact and modular optical terminals small enough to deploy from a backpack, and space terminals that support high speed optical links from LEO out to the Moon.

Equal Opportunity

• Azora is proud to be an equal opportunity employer.
• If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know by contacting info@azora.space.
