Senior Machine Design Engineer

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 Senior Machine Design Engineer to join Amentum’s Advanced Solutions Group. Candidates may be based at any one of our offices in Tullahoma, TN;
Farmington Hills, MI; 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.

Most of your designs will be unique, and you will usually be working on several projects at one time in a dynamic, challenging, and even fun environment. Many designs are “blank sheet of paper,” with few analogs or comparisons. This position will provide you with an exciting opportunity to lead and manage Machine Design projects as part of a multi‑discipline team of professionals.

We are looking for a Machine Design engineer who will work to ensure client satisfaction and deliver key Machine Design projects within scope, budget, and schedule. You should be a self‑motivated professional with at least 15+ years of progressive Machine Design experience.
