Precision Force Metrology Scientist

The scientific responsibility

Resolve nanonewton-scale forces without mistaking sensitivity for accuracy. Own traceability from angular readout through torque calibration and lever-arm geometry to reported force.

Technical depth we are looking for

Torsion mechanics; electrostatic or other independent torque standards; transfer functions; hysteresis; creep; calibration covariance.

We expect research-level command of the relevant physics and methods, plus the ability to explain assumptions to adjacent specialists. A doctorate or equivalent demonstrated achievement is appropriate; the evidence of your work matters more than a particular institution.

Evidence to bring

A force or torque measurement with an explicit uncertainty budget, calibration records and an account of drift or nonlinearity. State the frequency range and conditions.

Provide public or authorized links and distinguish your individual contribution from the team’s work. Include a failure, correction or negative result that improved your judgment. Do not send confidential material.

Your first design assignment

Compare independent calibration options and estimate their uncertainty across the proposed measurement bandwidth and torque range.

This is a proposed priority after appointment, not an unpaid application assignment. The exact scope follows funding, access to appropriate facilities and an agreed work plan.

The failure mode you must be able to expose

Using the photon-force prediction to calibrate the instrument and then claiming the same prediction has been independently verified.

A concrete first deliverable

A calibration architecture with reversal tests, traceability chain, range limits and recalibration triggers.

Acceptance should be based on inspectable records, stated limitations and independent technical review. A positive propulsion result is not a prerequisite for useful scientific work.

A question for our technical conversation

How would you separate scale-factor drift from a change in the applied force?
