About You

You're an engineer who thrives at the intersection of embedded systems and advanced

algorithms. You're equally comfortable optimizing interrupt latency in firmware, implementing a

phase-locked loop in an FPGA, and deriving Kalman filter equations on a whiteboard. You have

a deep appreciation for the physics and mathematics underlying precision timing and navigation

systems, but you're also a pragmatic engineer who knows how to ship production-ready code.

You've probably worked on challenging problems in GPS-denied navigation, timing systems, or

sensor fusion—and you're excited to apply that expertise to cutting-edge quantum devices.

You're comfortable working across the full stack from HDL/bare-metal firmware to high-level

algorithms, and you enjoy collaborating with physicists, hardware engineers, and customers to

translate requirements into robust implementations. Most importantly, you're passionate about

building technology that enhances resilience and security in critical infrastructure and defense

applications.
