Junior Physicist

FIELDLINE INDUSTRIES•Boulder, CO

9d•$80,000 - $110,000•Onsite

About The Position

FieldLine Industries is a Colorado-based quantum sensing company developing and manufacturing high-sensitivity quantum magnetometers and advanced multi-sensor systems. Our technology is being applied in a wide variety of application areas including navigation in GNSS-denied environments, unexploded ordnance detection, maritime sensing, and space systems. Our technology sits at the intersection of quantum physics, precision engineering, and real-world deployment—transforming applications in navigation, space and geographical mapping, geophysics, defense applications, and fundamental research. We’re a small, highly technical team that values solving problems together, with curiosity, rigor, reliability and humor. We are taking on several exciting projects this year, and are seeking a Junior Physicist to join the team. The Role: Work with the team in the development, characterization, and operation of quantum magnetometers, from laboratory experiments through integration and deployment in real-world Platforms.

Requirements

BS or MS in physics, applied physics, electrical engineering, or a related field.
Hands-on laboratory experience with optics and lasers.
Experience with Python for data analysis and automation.
Working knowledge of electronics and electrical measurements, including oscilloscopes, lock-in amplifiers, and basic noise concepts.
Willingness to perform field work, including travel and working in outdoor conditions.

Nice To Haves

Experience with optical, atomic, or quantum sensors.
Experience with low-noise measurements and instrumentation.
Basic mechanical design skills, including CAD and/or 3D printing for payload mounts.
Experience with embedded systems or instrument control, such as Arduino, Raspberry Pi, or DAQ hardware.

Responsibilities

Test and characterize quantum magnetometers, benchmarking their performance against component specifications and identifying sources of noise and performance limitations.
Support sensor development by designing and implementing tabletop experimental setups, collecting and analyzing data.
Work with the team to automate measurement procedures and control laboratory instrumentation.
Support sensor integration into platforms and their deployment in the field.
Document experimental procedures and results and present findings at internal and external meetings.
