We are building something never done before.
Helion is a fusion power company based in Everett, WA, with the mission to build the world’s first fusion power plant, enabling a future with unlimited clean electricity.
We are a team of engineers, scientists, and makers that believe fusion energy can solve climate change on a global scale and ensure energy independence while making electricity more affordable than ever before.
Now is a great time to join Helion! Bring your skills, experiences, and determination to make a difference in the world. Together, we can make a future with unlimited clean electricity from fusion a reality!
What You Will Be Doing:
We are looking for a Nuclear Engineer to perform neutronics analysis on our detailed CAD models of our fusion generators. As part of our Radiation Safety and Nuclear Science team, you will work closely with our Design Engineers to create a workflow that creates Monte Carlo input from CAD models. You will report to our Director of Radiation Safety and Nuclear Science at our Everett, WA office.
You Will:
-
Learn how to use commercially available software (e.g., Attila/Attila4MC) to create unstructured meshes and perform variance reduction
-
Parse bills of materials generated by the engineering team to populate materials into the unstructured mesh. This workflow is meant to estimate important metrics such as shutdown dose rate and decay heat. Other codes may be used
-
Create workflow to estimate dose and part-by-part decay heat during operation and shutdown conditions for our fusion generators
-
Analyze complex CAD geometries in Monte Carlo (e.g., MCNP) and deterministic codes, using software like Attila/Attila4MC
-
Perform neutron activation calculations on detailed geometries
-
Use variance reduction and other methods to reduce computation run time, e.g., Attila/Attila4MC and CADIS/FW-CADIS to create weight windows
Required Skills:
-
An understanding of nuclear physics, including neutron interactions, photon interactions, cross sections, attenuation, radioactive decay, and other types of radiation
-
2+ years of experience beyond coursework using a Monte Carlo radiation transport code (e.g., MCNP, OpenMC, Geant4, FLUKA, FISPACT, SERPENT, or TRIPOLI)
-
2+ years of experience beyond coursework using a common coding language (Python, MATLAB, C++) to read/write files, analyze data, and run other software, and experience maintaining a small-scale code repository/version control
-
Experience submitting jobs to a high-performance computing group
-
Demonstrated experience verifying/validating simulated data by comparing it to physical measurements
-
Can obtain a license for MCNP6
The pay range for this position is $110k-175k. This pay range may be inclusive of several career levels and will be narrowed based on several factors, including the candidate’s experience and qualifications.
