About The Position

Core One is seeking a Field Engineer to join our team. Our mission is to be at the forefront of devising analytical, operational, and technical solutions to our Nation's most complex national security challenges. We value people first and are committed to recruiting, nurturing, and retaining top talent, offering a competitive total compensation package. This role carries the technical depth of a systems engineer but applies it in the field, where the engineer is frequently the only technical presence on site and must diagnose and resolve issues independently. Success requires a strong hands-on foundation across networking, server administration, and endpoint support, combined with customer-facing judgment and adaptability to work effectively in unfamiliar environments under schedule pressure.
