Engineering Internship - Summer 2025
Antares
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, 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 2025 class has three slots available for the following roles:
Mechanical R&D / Test Engineering
Manufacturing Engineering
Materials and Processes Engineering
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 you’re 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 bachelor’s degree program, with first semester in-major junior-level coursework completed by start of internship
Must have prior internship experience, or significant (>1yr) project team 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
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”
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 beginner’s 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
