Job Description

About us

We are a building the manufacturing backbone of the quantum economy. We specialize in chip-scale quantum devices-starting with clocks and sensors-that unlock resilient Position, Navigation, and Timing (PNT) systems. Our team blends cutting-edge quantum physics with precision manufacturing and systems engineering to create scalable hardware that works beyond the lab. Backed by leading deep-tech investors and the U.S. Department of Defense, we're growing fast-and looking for exceptional engineers to join us.

Role Overview

We're seeking an RF & Analog Electronics Engineer to lead the design and development of precision, low-noise, mixed-signal electronics for our quantum devices. You'll work across disciplines to integrate electronics with optics, vacuum, and quantum systems-contributing to the heart of a new class of quantum sensors.

This is a hands-on, deeply technical role that will shape the future of our products and platform.

Key Responsibilities

• Design and characterize low-noise, low-tempco analog circuits , including amplifiers, filters, voltage regulators, and PID controllers
• Build and optimize precision signal chains for atom-based quantum systems
• Develop RF and microwave circuits including low SWaP synthesizers, PLLs, modulators, and impedance-matched front-ends (3 4 GHz)
• Perform PCB layout for high-frequency, low-noise, and mixed-signal circuits, including multilayer compact boards
• Collaborate closely with AMO and systems teams to co-design electronics with lasers, photodiodes, and MEMS packaging
• Prototype, test, and iterate using tools like oscilloscopes, spectrum analyzers, lock-in amps, VNAs, and Allan deviation analyzers
• Develop and automate test setups for performance validation and data logging
• Support EMI/EMC mitigation and qualification for defense/aerospace standards (MIL-STD)

Core Skill Areas

Analog & Mixed-Signal Electronics

• Low-noise analog design & signal conditioning
• PID loop design, control theory, and circuit implementation
• ADC/DAC integration
• Precision power regulation and current drivers (e.g., for laser diodes)
• Low-distortion analog front ends

RF & Microwave Systems

• Oscillator and synthesizer design (3 5 GHz range)
• Impedance matching and signal integrity
• Compact, low-power RF circuit design

System Integration

• PCB design with Altium or KiCad
• Co-design with photonics/optical systems
• SPICE and RF simulation tools (LTspice, ADS, HFSS)
• Git/Gitlab for version control
• Python for automation and data processing

Bonus Skills

• Experience with atomic physics principles (e.g., rubidium or cesium transitions)
• Familiarity with MEMS integration, vacuum systems, and optoelectronic packaging
• Prior work on qualification for aerospace or defense applications
• DSP circuit or firmware development
• Design for high-volume manufacturability (DFM)

Who You Are

• You care about building real hardware that ships.
• You are detail-obsessed, hands-on, and love solving hard technical problems.
• You thrive in interdisciplinary environments and want to work closely with physicists, engineers, and product teams.
• You want your work to matter-to defense, to infrastructure, to the future of quantum.
