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.

The Antares team hails from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, Rigetti Computing, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Idaho, Oak Ridge, Los Alamos, and Savannah River. Antares has raised over $600M in venture capital from top-tier investors and has hundreds of million-dollars on contract with the military services, NASA, and the Department of Energy.

About the Role

As an analyst at Antares your primary responsibility will be building and running thermal-structural models of components and subsystems throughout the reactor core and power conversion system to ensure our designs will meet thermal, mechanical, operational, and performance requirements within the extreme environments of our R1 micro-reactor. Design engineers will rely on your modeling and technical expertise for iterative design feedback and optimization, while adhering to best practices for DFM (design for manufacturing) and maintaining a rapid pace of development.

Antares aims to maintain close collaboration between testing and analysis teams, and to this end you may often be asked to provide technical support before, during, and after test campaigns. This may take the form of cooperative planning of testing goals, instrumentation requests, root cause analysis in the event of failures, post-test data review, and model validation/anchoring.

Roles and Responsibilities

Build, run, and maintain FEA (Finite Element Analysis) models of reactor components and subsystem assemblies

Provide thermal-mechanical assessments of designs and ensure they meet the static, dynamic, thermal, fatigue, and creep requirements set out by Antares and our regulatory agencies

Collaborate with designers and responsible engineers to provide guidance on initial sizing, material selection, and design feedback based on analytical results

Compile detailed documentation of analytical results and communicate key results, assumptions, and limitations to key stakeholders throughout the company

Provide support to test engineers in the form of collaborative test design, instrumentation selection, and data review to ensure test campaigns provide the necessary data to validate our models

Develop internal tools and calculators to enable other engineers to quickly and independently perform analytical assessments of their designs without the need for detailed finite element models

Provide technical mentorship and guidance to other engineers and across teams
