Job summary

Hexium is modernizing AVLIS into scalable industrial technology for domestic isotope production. We are seeking a Senior Electrical Engineer to own and build diagnostics, precision instrumentation, and custom controllers used with laser and separation systems.

You will take designs from concept through prototyping, testing, and integration with larger systems, focusing on reliable sensor data capture and hardware bench work.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering with a strong analog/instrumentation focus.
• 5+ years of hands‑on experience designing low-noise analog instrumentation for sensitive or low-level signal measurement.
• Demonstrated experience measuring fast transient, low-current, or low-voltage pulses (photodiode, particle/ion detector, or similar signal chains).
• Schematic capture and PCB design experience.
• Comfortable with iterative, trial-and-error hardware development in an R&D lab setting.

Responsibilities

• Design low-noise analog front-ends (transimpedance amplifiers, charge amplifiers, precision signal conditioning).
• Develop custom signal-amplification and detection electronics for applications like mass spectrometers.
• Design and build controller assemblies for test diagnostics and signal processing.
• Own the full instrument development cycle: schematic capture, PCB layout, prototyping, bench characterization, hardware iteration.
• Integrate diagnostic electronics with DAQ and control systems for real-time operation.
• Work with scientists to translate measurement requirements into working hardware.
• Support installation, commissioning, and troubleshooting of new control and electrical hardware.
