Summer 2026 Engineering Internship

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 Ultra Safe Nuclear and Los Alamos National Laboratory. Antares has raised over $39M in venture capital from top-tier investors and has over $4M in government funding.

Internships Available

The Summer 2026 class has slots available for the following roles:

• Mechanical R&D / Test Engineering

• Manufacturing Engineering

• Mechanical Design Engineering

• Electrical Engineering

• Software Engineering

• Nuclear Engineering / Physics

Interns will be tasked with small starter projects and then quickly tasked with a long-duration project that will culminate in a technical deliverable and presentation. You will be integrated and evaluated as if you are a first-year junior engineer not just an intern. The bar for success here is high and the expectation is that youre able to smartly use your mentor and the resources around you to execute on your project and identify more issues and opportunities for improvement.

Basic Qualifications:

• Enrolled in at least a bachelors degree program and going into your Junior or Senior year of studies

• Must have prior internship experience or significant (>1yr) project team laboratory or research experience

Preferred Skills & Experience:

• GPA of 3.5 or above

• Experience in a University club or organization leadership role preferred

• Strong interpersonal and technical communication skills (examples: leading a student project team presenting research at conferences etc.)

• Strong analytical and problem-solving skills with attention to detail

• Ability to work cross-departmentally with different groups and teams

• Ability to work effectively in a dynamic environment with changing needs and requirements

• Ability to work independently and in a team take initiative and communicate effectively

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

• Craftsmen - We also focus on the inputs. We aspire to high-quality engineering for its own sake. As such we invest in personal growth learning and developing a long-term career path for exceptional individual contributors. We embrace a beginners mindset share knowledge and never condescend the curious

• Loyally Collaborative - Team > Self. We win together. There is nothing more precious than a high-performing team
