RF & Plasma Research Engineer
About The Position
Stellios Technologies is building advanced high power microwave and energy systems for defense, aerospace, and energy. We are hiring an exceptional RF & Plasma Research Engineer to build the computational models behind next generation high power microwave sources, RF systems, plasma interactions, and advanced energy systems. This is a computational research role with direct connection to hardware. Your job is not to generate beautiful simulations. Your job is to build models that predict reality, identify the physics that controls performance, and help the engineering team make better hardware decisions faster.
Requirements
- A PhD in electrical engineering, plasma physics, applied physics, computational physics, accelerator science, or a directly relevant field, OR a BS or MS in a relevant technical field plus at least 5 years of directly relevant professional experience
- Strong fundamentals in electromagnetics and at least one of the following: plasma physics, beam physics, vacuum electronics, computational electromagnetics, particle in cell methods, RF systems, or accelerator physics.
- Ability to write code, interrogate a numerical model, recognize when a solver is lying, and reduce a complicated simulation result back to first principles.
- Experience validating models against real experiments.
- Comfortable working around high voltage, vacuum systems, RF diagnostics, precision microwave hardware, and multidisciplinary engineering teams.
- Must qualify as a U.S. person under applicable export control laws (U.S. citizens, U.S. nationals, lawful permanent residents, refugees, and asylees).
- Willingness to work on site in New Mexico, Southern California, or Austin.
Nice To Haves
- Purely academic experience can be excellent if the work involved serious simulation development, experimental comparison, or difficult computational physics.
Responsibilities
- Electromagnetic modeling of cavities, waveguides, resonators, mode converters, launchers, antennas, and high power RF structures
- Particle in cell and beam wave interaction modeling for klystrons, gyrotrons, electron beam systems, and related devices
- Plasma modeling relevant to high power microwave propagation, plasma interaction, breakdown, and advanced energy systems
- Reduced order models and first principles calculations used to sanity check large simulations
- Numerical optimization, parameter sweeps, uncertainty analysis, and design space exploration
- Model validation against analytic limits, published benchmarks, component tests, and full system experimental data
- Development of internal Python, C++, Julia, MATLAB, or equivalent tools that accelerate engineering analysis
- Integration of commercial solvers and open source codes into repeatable computational workflows
- Close collaboration with RF, HPM, power systems, magnet, thermal, mechanical, and experimental engineers
- Technical research that can translate into new products, patents, and publications where appropriate
Benefits
- 100% Employer-Paid Health Insurance Premiums
- Competitive PTO and paid company holidays
- Equity Package with meaningful ownership potential
- Competitive base salary commensurate with experience and expertise
