Senior Engineer Space Electronics

IonQ•Pleasanton, CA

2d•Onsite

About The Position

IonQ, Inc. is a leading quantum platform and merchant supplier, delivering integrated quantum solutions. Vector Atomic, an IonQ company, is building quantum technology to transform navigation, timing, geophysical exploration, and telecommunications. This role is based onsite in Pleasanton, CA, with up to 5% travel. We are seeking experienced electronic engineers to join a multidisciplinary team of physicists and engineers. In this role, you will lead the design of advanced electronics for next-generation quantum sensors, focusing on specifying, designing, characterizing, and testing PCB assemblies with complex FPGA, MCU, mixed-signal, and RF architectures. Designs must meet stringent reliability and environmental requirements for Low Earth Orbit (LEO) missions. You will drive the full lifecycle of electronic subsystem development and develop innovative solutions for novel quantum instruments.

Requirements

Bachelor’s degree in Electrical Engineering (or related field) with 6+ years of experience, or a Master’s degree with 3+ years.
Minimum 3 years of experience designing electronics for space applications, particularly LEO missions.
Experience designing power, analog, and mixed-signal circuits for satellite systems.
Familiarity with radiation testing (TID, SEE) and mitigation techniques.
Background in selecting and qualifying components for radiation performance, including COTS parts requiring verification testing.
Proficiency with circuit simulation tools such as LTSpice.
Expertise in high-speed PCB design techniques: microstrip, controlled impedance, length matching, grounding, decoupling, and shielding.
Skilled with lab equipment such as oscilloscopes, VNAs, spectrum analyzers, power supplies, function generators, and DVMs.
Comfortable working in a laboratory environment.
Strong written and verbal communication skills for cross-functional collaboration.
Must be a U.S. citizen (born or naturalized), lawful U.S. permanent resident (i.e. green card holder), or certain categories of refugees, and asylees to comply with US export control laws.

Nice To Haves

Experience with space-qualified microprocessors or FPGA families.
Background developing FPGA RTL or algorithms, including TMR and SEU mitigation.
Understanding of digital signal processing techniques and FPGA implementation constraints.
Experience with AS9100-compliant processes is a plus.

Responsibilities

Lead the high-level electrical architecture for next-generation quantum sensors, balancing size, weight, power, and performance (SWaPC).
Collaborate across disciplines to translate system requirements into detailed electronic designs.
Own end-to-end PCB development, including requirements definition, schematic design, layout, fabrication coordination, and performance verification.
Support system integration and testing to ensure instrument-level requirements are met.
Develop new circuits and adapt existing designs for reliable operation in LEO.
Partner with firmware and RTL engineers to implement radiation-tolerant techniques such as error detection/correction, bit scrubbing, and recovery methods.
Create environmental test plans simulating LEO conditions; estimate FIT rates and electronics lifetimes based on mission parameters.
Oversee testing at external facilities and refine test protocols to optimize outcomes.
Use electronic test and measurement equipment to characterize and validate design performance.
