Top pay: highest pay, longest training
Atomic Clock Scientist: Builds the atomic clocks that keep official time and make GPS work. Typical pay $150k.
Measurement Standards Scientist: Defines and protects the official meaning of a kilogram, a volt, and a meter. Typical pay $145k.
Synchrotron Beamline Scientist: Runs one 'station' at a giant ring that makes X-rays a billion times brighter than a hospital's. Typical pay $135k.
Cryogenic Engineer: Designs systems that keep things colder than anywhere in nature, for rockets, MRI magnets, and quantum computers. Typical pay $120k.
Mid pay: solid pay, degree or apprenticeship
Metrologist: Makes sure measurements are accurate, which is essential for everything from airplane parts to medicines. Typical pay $92k.
Calibration Technician: Tests and adjusts measuring instruments so they read exactly right. Typical pay $64k.
Instrumentation & Control Technician: Maintains the sensors and control systems that run power plants, refineries, and water plants. Typical pay $75k.
Research Electronics Technician: Designs and fixes the custom electronics that scientists need for their experiments. Typical pay $72k.
