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

Antares is looking for a Strategic Finance Associate to join our growing Finance organization. You will work directly with the Head of Finance and company leadership on some of the most important financial and strategic decisions facing the business.

This is not a traditional FP&A role.

You will work across corporate finance, financial modeling, manufacturing economics, capital allocation, commercial and government programs, fundraising, and long-range planning. You'll help translate complex technical and operational decisions into their financial implications and provide leadership with the analysis needed to make better decisions as Antares scales.

This is an ideal opportunity for someone with a strong foundation in investment banking, investing, or strategic finance who wants to move closer to the operating side of a rapidly growing hard-tech company.

5+ years of relevant experience across investment banking, private equity/growth investing, strategic finance, corporate finance, or a high-growth operating company

Strong understanding of financial statements, valuation, corporate finance, and investment analysis

Ability to take ambiguous business questions, structure the problem, perform the analysis, and communicate a clear recommendation
