Nuclear Engineer - Diagnostics at Helion in Everett, WA | USD102,000-130,000 | Kablio

Role

Description

neural nets

plasma diagnostics

multivariate optimization

algorithm development

simulation codes

data extraction

Develop neural nets to predict plasma simulation outputs from inputs. Adapt such neural nets to be training tools for new operators to develop intuition on FRC formation and translation
Operate and analyze nuclear and plasma diagnostics on test beds and Helion's fusion systems: Polaris and Orion
Perform multivariate optimizations as part of design processes and data analysis. E.g., optimize machine operating settings, machine architecture trades, or shield designs parameters
Write algorithms to extract information from noisy diagnostic data. E.g., recover individual pulse information from piled-up signals
Run and analyze MHD or PIC plasma simulation codes

Requirements

master’s

python

linux

optimization

neural networks

diagnostic data

Master's degree in nuclear engineering, plasma physics, or equivalent experience documented by a presentation at a technical conference
Hands-on experience analyzing diagnostic data or running plasma simulation codes
3+ years of experience writing scripts to analyze data using Python, MATLAB, C++, or a similar language. Techniques include vectorization, reading/writing data files in loops, and version control using tools such as SVN or git repositories
Plasma code experience including: running MHD or PIC codes, modifying input files, operating in Linux environments, and analyzing raw outputs to extract plasma parameters
Experience solving multivariate optimization problems using methods such as gradient descent or genetic algorithms
Diagnostic data experience includes: processing signals from digitizers/oscilloscopes, performing data cleaning (e.g., pile-up rejection), and deriving physical insights
Experience building neural networks to predict outputs from simulation inputs or to process noisy diagnostic data

Company

Overview

100M °C

Plasma Temperature

Achieved a plasma temperature of 100 million degrees Celsius, a critical milestone in fusion energy.

$1B

VC Funding

Received over $1 billion in venture capital funding to support their fusion energy research and development.

$5B

Valuation

Valued at over $5 billion in their Series F funding round, reflecting strong investor confidence in their fusion technology.

50 MW

Power Plant

Aiming to deliver a 50 MW fusion-generated electricity plant by 2028, marking a significant step toward commercial fusion energy.

Pursues a bold vision: taming the power of stars on Earth through fusion energy.
Develops magneto-inertial fusion technology, merging plasma at extreme speeds and capturing energy directly.
Pioneers in aneutronic fusion, recycling byproducts to generate helium-3, a sustainable fuel source.
Shifts from lab-scale to industrial-scale fusion with the Polaris device, supported by legal agreements.
Aims for rapid iteration with reactor designs capable of one pulse per second, enabling modular fusion systems.

Culture + Values

Build with urgency
Take ownership
Execute rigorously
Deliver hard truths

Environment + Sustainability

$500M in 2021

Investment Figure

Raised $500 million in 2021 to accelerate the development of their net-electricity target device, Polaris.

100M°C

Plasma Temperature Achievement

Achieved a milestone by heating plasma to 100 million degrees Celsius in June 2021.

500 MWe
