Position Summary & Responsibilities

Hexium is modernizing Atomic Vapor Laser Isotope Separation (AVLIS) into a scalable industrial technology for domestic isotope production. We are designing and building complex systems combining high-power lasers, electro-optics, precision controls, instrumentation, and custom electronics.

Our engineers work directly on the hardware, from initial design and prototyping through integration and testing. For a Senior Electrical Engineer, that means technical ownership of systems that are central to Hexium’s technology and to critical U.S. energy and national-security supply chains.

Role

We’re looking for a Senior Electrical Engineer to design and build the sensitive diagnostics, precision instrumentation, and custom controllers our laser and separation technology depends on. This is a hands-on, iterative design role within our Technology Development group, focused on developing electronics that can reliably capture and process sensor and signal data in complex experimental environments.

You’ll take designs from a blank schematic through component selection, prototyping, bench testing, debugging, and integration with larger systems. The ideal candidate has deep experience with precision analog design and is equally comfortable designing circuits and working directly with hardware on the bench.

Key Responsibilities

Design low-noise analog front-ends (transimpedance amplifiers, charge amplifiers, precision signal conditioning) for sensitive, fast-transient measurements
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 directly with scientists to translate measurement requirements into working hardware
Support installation, commissioning, and troubleshooting of new control and electrical hardware

Required 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 instr

Key Role Competencies & Evaluation Highlights

Key Role Focus:

Evaluating raw technical execution speed paired with zero ego and high autonomy in distributed systems.

📋 Preparation Priorities (Key Areas to Clarify):

1. Over-engineering simple features or delaying shipping for perfection
2. Blaming teammates or past management for project failures
3. Inability to explain complex technical concepts simply to non-technical stakeholders

✨ Recommended Role Alignment Hook:

I build hyper-scalable systems with an uncompromising focus on shipping velocity, and I want to help Hexium cut deployment times in half.
