Machine Design Engineer II

Amentum is a global leader in advanced engineering and innovative solutions, supporting critical missions across defense, intelligence, energy, and civilian sectors. Our people are our competitive advantage, driven by purpose, collaboration, and a commitment to delivering excellence for our customers and communities.

We are seeking a Machine Design Engineer II to join Amentum’s Advanced Solutions Group. Candidates may be based at either of our offices in Tullahoma, TN, or Greenville, SC.

Our Advanced Solutions Group delivers the design, construction, and operation of unique and complex research and development facilities across the nuclear, automotive, motorsports, defense, and aerospace industries.
