About The Position

At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history. Northrop Grumman Mission Systems is looking for you to join our team as a Principal Microelectronics Semiconductor Metals Process Engineer for our Advanced Packaging Technology facility in Apopka, FL . The Principal Microelectronic Semiconductor Metals Process Engineer will provide senior fabrication support and technical direction for a wide range of metals processes and tools for semiconductor wafers. The selected candidate will own the responsibility for process technology development and production deployment for multiple metal interconnect processes, including PVD and solder bumps fabricated across multiple equipment systems. They will collaborate closely with other process owners for back-end post-processing to ensure satisfactory integration of under bump metallization and sphere drop processes into overall product flows for both production parts, as well as new process and product development activities. The chosen candidate must have excellent verbal and written communication skills; be able to multitask in a fast-paced, dynamic, and high-visibility environment; and work well as part of a team. The position will demand large amounts of time working in a cleanroom environment. Some lifting and standing will be required.
