About the Company
Our client is pioneering next-generation chip-scale quantum devices, with a focus on advancing Position, Navigation, and Timing (PNT) systems. These systems are built to operate with resilience and precision, even in GPS-denied environments. At the intersection of quantum physics, high-precision manufacturing, and systems engineering, their work supports national security, infrastructure, and the future of quantum-enabled technologies. With strong backing from top-tier deep-tech investors and U.S. government agencies, the company is entering a phase of rapid growth and is seeking exceptional talent to support its mission.
Position Overview
We're looking for an experienced RF & Analog Electronics Engineer to lead the development of ultra-low-noise, high-precision, mixed-signal electronics at the core of compact quantum devices. This is a deeply technical and hands-on role, contributing directly to the architecture and performance of novel sensing platforms. The engineer will collaborate across optics, vacuum, and quantum teams to co-develop integrated systems ready for real-world deployment.
Key Responsibilities
- Design and characterize low-noise analog circuits: amplifiers, filters, PID controllers, voltage/current regulators
- Develop and optimize precision signal chains for quantum sensor platforms
- Design RF/microwave systems: synthesizers, PLLs, modulators, impedance-matched front-ends (3-4 GHz)
- Execute high-frequency, low-noise PCB layout and multilayer board design
- Collaborate with optical and systems engineers to co-design electronics with lasers, detectors, and MEMS packaging
- Build, test, and iterate using lab tools (oscilloscopes, spectrum analyzers, lock-in amps, VNAs, Allan deviation analyzers)
- Develop automated test systems for performance validation and long-term data capture
- Support compliance and mitigation for EMI/EMC under aerospace and defense standards
Core Technical Focus Areas
Analog & Mixed-Signal Design
- Low-noise analog signal conditioning
- PID control loop design and implementation
- Integration of ADCs/DACs into high-precision systems
- Power regulation and current driving circuits for sensitive components
RF & Microwave Systems
- Design of compact, low-power synthesizers (3-5 GHz)
- Signal integrity, impedance matching, and board-level RF performance
System-Level Integration
- PCB layout experience with Altium or KiCad
- Co-development with photonic systems and vacuum-integrated hardware
- Simulation tools: LTspice, ADS, HFSS, etc.
- Familiarity with version control (Git/GitLab)
- Python Scripting for automation and test infrastructure
Preferred Experience (Nice to Have)
- Background in atomic physics (eg, rubidium/cesium transitions)
- Exposure to MEMS, vacuum systems, or optoelectronic packaging
- Prior work in defense, aerospace, or other high-reliability applications
- Experience with Digital Signal Processing or Embedded firmware
- Knowledge of DFM for scaling into production
Ideal Candidate Profile
- Passionate about building high-performance hardware that works in the field
- Precision- and detail-oriented, with strong hands-on debugging and prototyping skills
- Enjoys working across disciplines and learning from adjacent technical areas
- Motivated by impactful work at the forefront of emerging technology
