Principal Engineer, Defense Environmental & Reliability Testing at Eurofins

About the Opportunity Eurofins Electrical & Electronics is expanding its Aerospace, Defense, and Military testing practice and is seeking a Principal Engineer to own and grow the Environmental Simulation and Reliability Lab in Baltimore. This is not a standard lab manager role. We are looking for a technical leader who has lived inside defense programs - someone who understands MIL-STD-810, DO-160, and reliability qualification from the engineering side, can run a high-performing lab, and can engage defense customers at the program level. This is a bench-present role. You are in the lab every day - running tests, reviewing data, setting procedures, and leading by technical example. If you are looking for a desk job, this is not it.
