Electrical Engineer

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. As an Electrical Engineer youll build systems that are central to Hexiums technology and to critical U.S. energy and national-security supply chains.

Role

Were looking for an Electrical Engineer to design build and test the power electronics power supplies and control hardware behind our laser and separation technology including high-temperature and induction heating hardware. This is a hands-on iterative design role within our Technology Development group with a focus on developing reliable multi-kilowatt power systems for complex experimental environments. Beyond power systems youll contribute to instrumentation diagnostics and lab controls work across the company.

The ideal candidate has practical experience designing and testing power electronics. Theyre comfortable around high-voltage hardware and enjoy solving hard problems through hands-on experimentation and close collaboration with scientists and mechanical engineers.

Key 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 lab 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: 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

Required Qualifications

• Bachelors Degree in Electrical Engineering or a closely related field (e.g. Engineering Physics Computer Engineering)
• 3 years of hands-on electrical hardware design experience
• Hands-on design and test experience in power electronics (inverters motor drives power supplies induction heating)
• Experience with schematic capture and PCB design (Altium KiCad Allegro or similar) and circuit simulation (SPICE PLECS or similar)
• Confident with lab test equipment (oscilloscopes differential and current probes power analyzers) and with iterative trial-and-error hardware development
• Able to work safely with high-voltage equipment
• Able to work on-site in Austin TX
• Candidates must be eligible to obtain and maintain a DOE Q-level security clearance
• This role will be exposed to export-controlled information and requires compliance with applicable export control laws and regulations

Preferred Qualifications

• 5 years of hands-on electrical hardware design experience
• Experience with induction heating or resonant power converters (series/parallel resonant LLC soft switching)
• Experience with IGBT or SiC MOSFET power stages gate drivers magnetics design (Litz wire matching transformers) and water-cooled power hardware
• Electromagnetic or thermal simulation (COMSOL ANSYS Maxwell or similar) for coil and load design
• Low-noise analog design: transimpedance or charge amplifiers lock-in amplifiers or ion detection and spectrometry electronics
• High-temperature measurement and control (thermocouples pyrometers closed-loop temperature control)
• Embedded or lab control experience (microcontrollers PLCs LabVIEW or Python for DAQ)
• Background in a national lab university research group or hardware startup
• Currently holds an active DOE Q or DoD TS clearance

Physical Requirements

• Extended periods at a lab bench performing fine-motor tasks (soldering board assembly probing) requiring sustained hand-eye coordination and dexterity
• Ability to work near energized high-power and high-temperature equipment and in laser-controlled areas under lab safety protocols (may require laser safety training/certification and PPE use)
• Occasional lifting/carrying of test equipment up to 30 lbs
• Frequent close-vision work (component-level inspection microscope/magnification use)

Work Environment

On-site role based in Austin TX. Primarily lab-based split between electronics benches high-power test areas and a controlled laser lab. This is an on-site hands-on role with limited remote flexibility given the equipment and hardware dependencies. Work in laser-controlled areas requires lab safety training (LSO-administered) and high-power work follows Hexiums electrical safety procedures.

Benefits

• Stock Options
• Paid Time Off
• 401(k) Matching
• Medical Dental Vision insurance
• HSA & FSAs
