What are the key skills and qualifications needed to thrive as a Radiation Shielding Engineer, and why are they important?

To thrive as a Radiation Shielding Engineer, you need a solid background in physics, mathematics, and engineering principles, usually supported by a degree in nuclear, mechanical, or health physics engineering. Familiarity with Monte Carlo simulation software, radiation transport codes (such as MCNP or FLUKA), and relevant safety regulations is typically required. Strong analytical thinking, attention to detail, and effective communication are standout soft skills in this role. These competencies are vital for designing safe environments, ensuring regulatory compliance, and effectively conveying complex technical information.

What is a Radiation Shielding Engineer?

A Radiation Shielding Engineer is a specialized professional who designs and implements protective barriers to shield people, equipment, and the environment from harmful ionizing radiation. They work in industries such as nuclear power, medical imaging, and research laboratories to ensure that radiation exposure stays within safe limits. Their responsibilities include analyzing radiation levels, selecting appropriate materials for shielding, and ensuring compliance with safety regulations. Radiation Shielding Engineers play a vital role in protecting public health and safety where radiation is present.

What are some common challenges faced by Radiation Shielding Engineers when designing protective barriers for new facilities?

Radiation Shielding Engineers often encounter challenges such as balancing strict regulatory requirements with practical construction limitations and budget constraints. They must accurately model radiation sources and interactions with various materials, which requires a strong understanding of both physics and engineering software. Collaboration with architects, health physicists, and construction teams is crucial to ensure that shielding designs are both effective and feasible. Staying updated with evolving safety standards and integrating new technologies can also present ongoing professional challenges.

What is the difference between Radiation Shielding Engineer vs Nuclear Safety Engineer?

AspectRadiation Shielding EngineerNuclear Safety Engineer
CredentialsEngineering degree, certifications in radiation safetyEngineering or science degree, nuclear safety certifications
Work EnvironmentResearch labs, nuclear power plants, medical facilitiesNuclear plants, regulatory agencies, safety analysis environments
Industry UsageDesigning shielding for radiation protectionEnsuring nuclear plant safety and compliance

Radiation Shielding Engineers focus on designing and implementing shielding solutions to protect against radiation exposure, often working in medical, research, or nuclear power settings. Nuclear Safety Engineers concentrate on maintaining safety standards, risk assessments, and regulatory compliance within nuclear facilities. While both roles require knowledge of radiation and safety protocols, their primary responsibilities and work environments differ.

Job description

About Us
At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We're fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we're building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space.
Formed in 2023, the Antares team hails from SpaceX, The White House, MIT, Rigetti Computing, The Air Force, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Los Alamos, Idaho, and Oak Ridge. Antares has raised over $130M in venture capital from top-tier investors and has over $13M in government funding.
About the Role
As a member of the Licensing and Safety Analysis team, you will be the responsible engineer for the characterization of radiation sources as well as the design and analysis of radiation shielding for reactor operation, shutdown conditions, as well as post operation transportation, storage, and disposition. You will apply best available analysis tools to characterize radiation sources from fission, activation, and decay. You will work as an integral member of the reactor and site design team to design and analyze the best available shielding configuration to meet customer requirements for a variety of deployment scenarios.
The ideal candidate has a mix of industry and academic experience and has worked in a team-oriented environment to develop nuclear technologies for real-world applications. While you may have an area of expertise, you're not afraid to operate as a generalist in a growing organization.
Roles and Responsibilities:
You will develop and provide expertise in a subset of the following:
  • Ownership of radiation shielding design and analysis
  • Development of trade studies of materials choices
  • Development of neutronics simulations to characterize radiation sources during operation and in post-operation configurations
  • Optimization of radiation shielding for deployment and post-operation transportation.
  • Engagement in regulatory requirement compliance strategies and application to licensing pathways.
  • Ensuring utilized tools and analyses are established and maintained in comliance with Antares quality assurance program.

Basic Qualifications:
  • Bachelor's degree in nuclear or mechanical engineering, physics, material science, or related field
  • 3+ experience with radiation shielding analysis and design
  • Proficiency in modern radiation shielding analysis tools, such as MCNP/ADVANTG, SCALE/MAVRIC, or similar Monte Carlo variance reduction tools
  • Ability to navigate regulatory requirements, shielding design features, analysis tools and manufacturing methods.

Preferred Skills & Experience:
  • Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to modernize nuclear design and operation
  • Master's degree or PhD in nuclear engineering
  • Demonstrated track record of high impact in the achievement of team goals
  • Strong project management skills and effective communication of technical concepts across multi-disciplinary teams
  • Broad knowledge of nuclear interactions with material selections, especially for radiation shielding applications
  • Working knowledge of a programming language, preferably Python

Additional Requirements:
  • Ability to work long hours and weekends as necessary to support critical milestones
  • Ability to travel to regulatory locations as needed

Location
  • We are located in Torrance, CA in a 322,000 square foot, brand new facility featuring large open spaces for team collaboration, R&D, and production, as well as easy access to the 405, 105, and 110 freeways. Our facility is in the heart of Los Angeles' vibrant emerging tech ecosystem alongside many other high growth startups and enterprises.

Culture
At Antares, we like to specifically tie each role to our founding document's set of values-here are the top five cultural values we think you should believe at your core to be successful:
  • Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and emergent and path-dependent properties. First principles thinking alone is insufficient. Think probabilistically and then take action. "If you want to be certain, then you are apt to be obsolete." Over-optimizing the components often degrades the system
  • Obsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycle
  • Be Unconstrained by Convention - Our only limits are the laws of physics. Many, even experts, will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies, by definition, must accomplish the seemingly impossible. If it were easy, it would have already been done. Never shy away from a solution because it has never been tried before, and never choose to do something because that's "how it's always been done"
  • Go Where the Work Is - Never miss a chance to meet a customer, user, or stakeholder face to face, even if that means hopping on a plane. If you can't make it, find a teammate who can channel your intentions and go in your place. Deep work can be done from anywhere, but we believe teams are built in person, and aim to maximize our time together
  • Operate in the Grey - Embrace nuance in pursuit of truth. Question every fundamental assumption
