• Bachelor's degree in Engineering or a related technical discipline preferred.
• 4+ years of relevant engineering experience required, although the ideal candidate will bring considerably deeper technical experience.
• At least 2 years of experience within a GMP or similarly regulated manufacturing environment.
• Medical device manufacturing experience is preferred.
• Candidates from other highly regulated industries, including aerospace and automotive manufacturing, may also be considered.
• Ability to communicate complex technical concepts clearly and work effectively across multidisciplinary teams.
• Willingness to work onsite in the Denver, Colorado area.
