Job Description
BAE Systems is looking for a qualified Systems Engineer to join our team in support of Program Acquisition for the MK21A Reentry Vehicle Development Program as required by the warfighter, Air Force Global Strike Command. This position will support the newly formed Integration IPT, focusing specifically on the electrical interfaces between the Mk21A reentry vehicle and the Sentinel ICBM platform.
We're seeking a Systems Engineer with experience in the integration and testing of complex systems, with a strong understanding of electrical engineering principles and interface design. Experience with Interface Control Documents (ICDs) and managing interface requirements is highly desirable. The candidate will be responsible for ensuring the reliable and robust electrical connection and communication between the Mk21A and the Sentinel, from pre-launch through reentry.
This is a dynamic and rewarding opportunity to shape the development and deployment of our nation's newest re-entry vehicle-the national security critical backbone of our nuclear deterrent capability. A successful candidate is creative, flexible, and comfortable handling diverse and sometimes conflicting priorities. Job location will be at Hill AFB, Utah.
Additional responsibilities include providing weapon system expertise in conducting integrated engineering-level assessments of analysis, production, verification, validation, operation, maintenance, and problem resolution processes as part of the program development cycle and to identify and mitigate design, production, and test deficiencies that could impact successful development.
Why BAE Systems? BAE Systems is the third-largest defense contractor in the world with an exceptional, mission-focused culture. Our employees have voted us a Top Workplace in Utah for five consecutive years, placing special emphasis on our healthy work-life balance. The 800+ BAE Systems employees and sub-contractors located at Hill AFB, Utah, support the Air Force Nuclear Weapons Center in sustaining the existing LGM-30G Minuteman III ICBM and acquiring its replacement, the LGM-35A Sentinel weapon system. We are a uniquely valued mission partner delivering technical excellence and innovative solutions to our Government customers.
Why Utah? You've got to see it to believe it! Utah is an amazing state with diverse geography, an eclectic culture and an exceptional quality of life. We are located north of Salt Lake City at the foot of the beautiful Wasatch Mountains. The area offers an incredible range of outdoor pursuits across the seasons, including hiking, climbing, hunting, fishing, camping, boating, and world-class skiing at resorts that hosted the 2002 Winter Olympics. The state is home to five national parks, and our location is an easy drive from three more. The Salt Lake City area offers a vast array of entertainment and cultural activities, including multiple professional sports teams. It is a western states hub for cutting-edge medical care with a range of nationally renowned specialty care centers and doctors. The Salt Lake International Airport is expanding and offers easy, direct access to locations across the globe. For applicants who are retired military service members, an additional advantage is Utah's recently enacted legislation making retired military pay non-taxable.
