About this role

<p><strong>Katalyst Description:</strong></p>

<p>Katalyst is an American technology company&nbsp;focused on dynamic space operations.&nbsp;&nbsp;We are building a fleet of&nbsp;dual-use multipurpose&nbsp;robotic space vehicles&nbsp;to&nbsp;create the&nbsp;future where maneuvering, upgrading, refueling,&nbsp;resupply&nbsp;and exploration are as routine as they are on Earth.
