Electrical Engineer

Hexium•Austin, TX

18d•Onsite

About The Position

Hexium is modernizing Atomic Vapor Laser Isotope Separation (AVLIS) into a scalable industrial technology for domestic isotope production. The company designs and builds systems combining high-power lasers, electro-optics, precision controls, instrumentation, and custom electronics. Engineers work directly with hardware from initial design and prototyping through integration and testing. The Electrical Engineer will design, build, and test power electronics, power supplies, and control hardware for laser and separation technology, including high-temperature and induction-heating hardware. This hands-on, iterative design role is part of the Technology Development group and focuses on reliable, multi-kilowatt power systems for complex experimental environments. The engineer will also contribute to instrumentation, diagnostics, and lab controls across the company. This is an on-site role based in Austin, Texas, primarily in laboratory settings that include electronics benches, high-power test areas, and a controlled laser lab. Remote flexibility is limited because of equipment and hardware dependencies. Work in laser-controlled areas requires lab safety training, and high-power work follows Hexium’s electrical safety procedures. The role is exposed to export-controlled information and requires compliance with applicable export control laws and regulations. Candidates must be eligible to obtain and maintain a DOE Q-level security clearance.

Requirements

Bachelor’s degree in Electrical Engineering or a closely related field, such as Engineering Physics or Computer Engineering.
At least 3 years of hands-on electrical hardware design experience.
Hands-on design and test experience in power electronics, such as inverters, motor drives, power supplies, or induction heating.
Experience with schematic capture and PCB design using Altium, KiCad, Allegro, or similar tools, and circuit simulation using SPICE, PLECS, or similar tools.
Confidence using laboratory test equipment, including oscilloscopes, differential and current probes, and power analyzers, and experience with iterative, trial-and-error hardware development.
Ability to work safely with high-voltage equipment.
Ability to work on-site in Austin, Texas.
Eligibility to obtain and maintain a DOE Q-level security clearance.
Ability to comply with applicable export control laws and regulations.

Nice To Haves

At least 5 years of hands-on electrical hardware design experience.
Experience with induction heating or resonant power converters, including series/parallel resonant, LLC, or soft-switching designs.
Experience with IGBT or SiC MOSFET power stages, gate drivers, magnetics design such as Litz wire or matching transformers, and water-cooled power hardware.
Experience with electromagnetic or thermal simulation using COMSOL, ANSYS Maxwell, or similar tools for coil and load design.
Experience with low-noise analog design, such as transimpedance or charge amplifiers, lock-in amplifiers, or ion detection and spectrometry electronics.
Experience with high-temperature measurement and control, including thermocouples, pyrometers, and closed-loop temperature control.
Embedded or laboratory control experience with microcontrollers, PLCs, LabVIEW, or Python for DAQ.
Background in a national laboratory, university research group, or hardware startup.
Currently holds an active DOE Q or DoD TS clearance.

Responsibilities

Design, build, and test power electronics and power supplies, including inverters and their control and protection circuitry.
Iterate hardware from bench-scale prototypes to robust, multi-kilowatt laboratory systems.
Develop control, feedback, and safety interlock systems for power and thermal processes.
Evaluate, specify, and integrate commercial power equipment alongside in-house designs.
Contribute to instrumentation and diagnostics projects, including sensor signal conditioning and data acquisition (DAQ).
Own the hardware development cycle, including schematic capture, PCB layout, prototyping, bench testing, and iteration.
Work directly with scientists and mechanical engineers to turn requirements into working hardware.
Support installation, commissioning, and troubleshooting of electrical and control hardware.
