Experimental Physicist

• Full-time

You will work with the entropy sources on the bench in our Palo Alto lab and with the superconducting hardware in our Chicago lab. You own attribution: tracing what these systems produce to their physical origin.

You would be part of the core team, with a seat in every decision that touches the program. Every member shapes what we build, and we expect you to drive the ideas that change our direction.

• A Master's degree (or an equivalent experimental record) in experimental physics, quantum optics, or precision measurement;
  PhD preferred.
• A record of tracing noise in a measurement chain to its physical origins — in quantum hardware, precision metrology, gravitational-wave detection, or optical systems.
• Time-series and spectral analysis: periodicities, non-stationarity, correlations.
• Analog front-end and data-acquisition artifacts: photodetector and amplifier noise, ADC and clock behavior, grounding and EMI.
• Experience characterizing or validating entropy sources or randomness generation.
• You have tested a hypothesis your field considered closed, and can show the result.

• ML on measurement streams.
• Optical bench experience: lasers, photodetectors, fiber, and their noise physics.
• Hands-on superconducting qubit measurement: coherence measurements, dispersive readout, microwave control.
• Microwave signal-chain fluency (IQ mixing, heterodyne readout, pulse shaping).
• Depth in TLS physics, flux noise, readout crosstalk, or amplifier-chain characterization.

• Attribute observed output structure to its physical origin, and state the disposition.
• Analyze output streams for periodicities, drift, correlations, and statistical significance.
• Characterization of the acquisition chain from detector to bits.

• Characterize and assess the entropy of the sources we are developing.
• Figures of merit for the ML-driven characterization pipelines our engineering team builds.
• Attribution reports that engineering acts on.
• Compensation: $240,000–$300,000 base plus equity, commensurate with experience.
• Relocation support if needed.
