About The Position

Northrop Grumman is hiring a Principal or Sr. Principal Manufacturing Engineer in Sunnyvale, California, to support welding and fabrication for marine propulsion and power generation systems. The role works with manufacturing processes for high-value gearing and steam turbine assemblies, machined components, and welded fabrications, including precision manual assembly, welding, bonding, and heat treatment of iron-based products. The position may be filled at level 3 (Principal) or level 4 (Sr. Principal), depending on candidate experience. The role is primarily onsite, with occasional offsite work possible with approval, and requires travel 10% of the time. Relocation assistance may be available. The engineer will develop and optimize manufacturing processes, welding procedures, tooling, fixtures, process flows, production layouts, and end-to-end manufacturing plans. They will evaluate processes and systems to reduce cost, improve sustainability, and establish best practices; support continuous improvement and new capital equipment; collaborate with design engineering on manufacturability; and lead qualification and certification of welding processes and personnel. The Principal level requires a bachelor's degree and at least 5 years of relevant experience, or a master's degree and at least 3 years. The Sr. Principal level requires a bachelor's degree and at least 8 years of relevant experience, or a master's degree and at least 6 years. Both levels require fabrication-process experience, the ability to read and interpret engineering drawings, technical writing and presentation experience, and U.S. citizenship. A bachelor's degree in Manufacturing Engineering or a similar field and experience with welding standards, robotic welding, additive manufacturing, or GD&T inspections are preferred. The primary-level salary range is $103,600–$155,400; the secondary-level range is $129,300–$193,900. Depending on the position, employees may be eligible for overtime, shift differential, and a discretionary bonus.
