Licensing Engineer

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.

Antares is seeking a Licensing Engineer to develop and execute licensing and permitting strategies for the Antares R1 product line and future commercial microreactor deployments. The engineer will prepare regulatory products, coordinate engagements, translate regulatory requirements into actionable design and program requirements, and drive comments and commitments to documented closure.

The role will support various regulatory pathways including Department of the Army, Department of Energy and Nuclear Regulatory Commission pathways. Work will include identifying applicable requirements, confirming that Antares design and licensing products satisfy those requirements, and coordinating with stakeholder groups to advance licensing and permitting. NRC work will focus primarily on the anticipated Part 57 pathway while drawing on other NRC frameworks and requirements as applicable.

The successful candidate will work closely with engineering, safety analysis, operations, quality, program management, customers, and regulators.

• Develop and execute licensing and regulatory engagement strategies.

• Identify applicable regulatory and permitting requirements and translate them into tangible design, analysis, programmatic, and documentation requirements.

• Prepare or coordinate licensing plans, technical briefs, white papers, topical reports, application content, responses to regulator questions, and other regulatory submittals.

• Track regulator and stakeholder comments, commitments, decisions, owners, due dates, resolution evidence, and closure status.

• Evaluate design and program products for compliance with applicable requirements and alignment with the licensing basis.

• Develop regulatory positions and evaluate alternative compliance approaches, including their technical, schedule, cost, and programmatic implications.

• Plan and support regulator and stakeholder engagements; present technical positions directly when appropriate and prepare leaders for higher-level engagements.

• Coordinate cross‑functional reviews with engineering, safety analysis, operations, quality, security, program management, and deployment teams.

• Maintain awareness of regulatory developments, guidance, precedent, and emerging licensing approaches relevant to advanced reactors.

• Support the development of scalable, repeatable licensing processes for future commercial deployments.

• Bachelor's degree in engineering or a closely related technical discipline.

• Experience in systems design or a highly regulated technical environment.

• Ability to interpret regulatory requirements and convert them into clear, implementable, and verifiable design or program requirements.

• Strong technical writing, organization, and communication skills.

• Ability to understand complex regulatory relationships and explain the basis for a proposed…
