Research And Development Design Engineer Jobs in Seattle, WA

Design Engineer II

Karman Space & Defense is a leader in the rapid design, development, and production of critical, next-generation system solutions that align with the U.S. Department of War and its allies’ core mission priorities, and meet the accelerating demand for access to space. Building on nearly 50 years of success, we deliver Payload & Protection Systems, Aero/Hydrodynamic Interstage Systems, and Propulsion & Launch Systems to more than 80 prime contractors supporting over 130 space and defense programs.

This role is part of our Hypersonics and Strategic Missile Defense business, which designs, develops, and delivers highly dependable missile systems for hypersonic and strategic missile defense missions. We provide integrated, mission-ready hardware that brings together multiple technologies into unified systems engineered to perform in demanding operational environments. Our tip-to-tail capabilities include payload protection and deployment systems, propulsion systems, aerodynamic interstage systems, separation systems, missile subsystems, shroud systems, launch systems, and payload integration solutions.

The Design Engineer contributes to the conceptualization, development, testing, and deployment of aerospace and flight‑worthy structures, mechanisms, and mechanical systems. This role supports design activities across the full lifecycle—from early concept creation through manufacturing and assembly—and plays an important part in new business development through technical inputs, design support, and proposal participation. The Design Engineer also provides mentorship to junior team members while collaborating closely with engineering, manufacturing, quality, and program staff.
