Responsibilities
You will be responsible for:
- Enhancing Helion’s analysis workflow for critical structures (electromagnets)
- Running transient multiphysics finite-element models to generate margins for critical designs
- Collaborating with a multidisciplinary engineering team to improve critical hardware designs
- Learning from in-house experts to expand your skillset into electrical and thermal analysis
- Building software tools to automate the analysis workflow and allow Helion engineers and scientists to run their own analysis
Requirements
- Bachelor’s degree in electrical engineering, applied mathematics, physics, or related field with a minimum of 3 years of hands-on engineering experience.
- Strong background in analytical, computational, and numerical simulation methods.
- Expert level understanding of electromagnetic and thermal finite element modeling.
- Experience in taking on complex analysis problems from formulation through hardware testing and model correlation.
- Proficiency with multiphysics finite-element analysis tools such as COSMOL, ANSYS, or equivalent.
- Experience with programming environments (Matlab, Python, etc.) for scripting, tooling, or data analysis.
- Familiarity with semiconductor physics, solid mechanics, and structural dynamics (modal, transient).
- Familiarity with Slurm or other high-performance computer cluster (HPC) batch schedulers.
- Desire to positively impact complex structural designs, rather than just execute on analysis.
We Offer
Our total compensation package includes benefits, including but not limited to:
