Q interstellar

<p>We are building a next-generation nuclear energy company focused on a single, standardized microreactor core deployed in two variants: terrestrial power and lunar/space power.</p>
<p>Our mission is to deliver portable, long-life, factory-fabricated nuclear systems that are safe, licensable, and scalable. We are seeking a Senior Nuclear Engineer to take technical ownership of reactor physics, neutronics, and core safety analysis for our unified reactor platform.</p>
<p>This role is central to the credibility, licensability, and long-term success of the company. You will work closely with systems, thermal, mechanical, and licensing teams to mature a reactor design intended for real deployment—not paper studies.</p>
<h2>Tasks</h2>
<p>Own reactor physics and neutronics analysis for the core across terrestrial and space variants</p>
<ul>
<li>Perform steady-state and transient analyses, including reactivity coefficients, kinetics parameters, shutdown margins, and power distributions</li>
<li>Develop, validate, and document modeling methods using Monte Carlo and deterministic tools</li>
<li>Support safety analysis, fault response modeling, and design basis events</li>
<li>Assess conservatism, uncertainties, and assumptions in nuclear calculations</li>
<li>Interface with systems, thermal-hydraulics, materials, and mechanical engineering teams</li>
<li>Contribute to licensing strategy, regulatory documentation, and external technical reviews</li>
<li>Mentor junior engineers as the team grows</li>
</ul>
<h2>Requirements</h2>
<ul>
<li>Degree in Nuclear Engineering or closely related field (MS or PhD preferred)</li>
<li>6+ years of experience in nuclear reactor analysis, design, or safety</li>
<li>Strong experience with neutronics tools such as <strong>MCNP, Serpent, OpenMC, SCALE</strong>, or equivalent</li>
<li>Experience documenting analysis methods for internal, regulatory, or external stakeholders</li>
<li>Ability to work across disciplines in a fast-moving technical environment</li>
</ul>
<h2>Benefits</h2>
<ul>
<li>Meaningful equity participation in a foundational nuclear platform</li>
<li>Competitive medical, dental, and vision coverage</li>
<li>Flexible PTO and paid holidays</li>
<li>Direct access to leadership and real technical authority</li>
<li>Opportunity to shape a reactor that will operate on Earth and beyond</li>
</ul>
<p>If you are motivated by building a reactor that will actually be deployed rather than endlessly redesigned, then we want to speak with you. This is a rare opportunity to help define a unified nuclear platform from first principles through operation.</p>
