Materials Engineer II

About Us

At Antares our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. Were fueled by the belief that advanced nuclear energy can strengthen our military solve the climate crisis elevate global living standards and expand humanitys presence in outer space. To achieve our mission were 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 Team

As a Materials Engineer you will aid in the development and qualification of all
materials in Antares reactor systems. This will consist of developing experiments
processes and quality control as well as working with vendors and collaborators to
identify and rectify critical gaps in material behavior at our operating conditions.
This position requires the ability to learn quickly and develop a deep understanding
of a wide range of materials including ceramics and metallic alloys such that you
become the go-to subject matter expert at the company. The ideal candidate will
apply fundamental knowledge of materials science to the practical applications of
manufacturing in a fast-paced environment while also pushing innovation for the
next generation of materials driving Antares to be a recognized leader in nuclear
materials

Roles and Responsibilities:

• Partake in the development and qualification for all materials in the reactor
  including lifetime testing cross-institutional collaboration and property
  evaluation

• Design and conduct physical thermal and mechanical testing of materials
  that replicates the reactor environment

• Employ statistical methods to systematically evaluate effects of process
  variables and environmental effects on materials properties

• Conduct materials characterization including root cause investigations of failure
  modes

• Interface with manufacturing neutronics mechanical testing and quality
  engineers to integrate materials into the overall system define limits to
  operating conditions based on material properties and optimize processes

Basic Qualifications:

• Bachelors degree in Mechanical Engineering Materials Engineering or a
  related field

• 3 years of experience in materials engineering

• Proficiency in optical or electron microscopy as well as mechanical property
  evaluation

• Experience with Materials characterization including root cause investigations of failure
  modes

Preferred Skills & Experience:

• 5 years demonstrated experience as part of integrated team in a production
  setting

• Knowledge of radiation effects in materials

• Knowledge of stainless steel Ni based superalloys and ceramics

• Knowledge of Graphite or other nuclear materials

• Coatings experience

• Exceptional communication skills to work effectively across teams and convey
  technical information to non-specialists

Additional Requirements:

• Ability to work long hours and weekends as necessary to support critical milestones

Location

• We are located in Torrance CA in a 145000 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 documents set of valueshere 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 thats how its 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 cant 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
