Northrop Grumman is seeking a Senior Principal Process Engineer to design and optimize manufacturing processes, particularly in additive manufacturing, to enhance material properties, minimize distortion, and maximize strength for advanced systems.
Requirements
- 6 years of experience in additive manufacturing and knowledge of properties and processing of aluminum alloy parts by additive manufacturing is required.
- 6 years of demonstrated work with tensile and fatigue testing and industry processes and requirements.
- Strong technical writing skill and the ability to write process documentation with minimal oversight.
- 4 years of experience incorporating feedback from various sources, including technicians, operators, and engineers, to ensure technical and ergonomic capabilities in processes.
- 4 years if of experience establishing standard operating procedures and engaging the operations team to ensure these are followed.
- Familiarity with industry and government specifications related to testing and performance of additive manufactured metal alloys is desired.
- Experience testing and reviewing performance data in accordance with internal and industry specifications.
Responsibilities
- Design and plan layouts for manufacturing processes, including additive manufacturing (metallic and non-metallic), heat treatment and alternative processes to minimize distortion and maximize strength, and surface finishing techniques such as chromate, anodizing, etching, polishing, and painting.
- Develop and implement pre- and post-processing methods to achieve required mechanical properties and oversee other material-processing operations.
- Plan the sequence of operations and specify procedures for cutting, shaping, and preparing materials, balancing technical requirements with cost-effectiveness.
- Conduct tests and measurements throughout research, evaluation, and production stages to monitor and control variables such as laser speed, recoater material, atmospheric exposure, shielding gas and flow rate, travel speed, and layer thickness, ensuring required density, yield strength, and elongation.
- Establish and submit processing requirements for the design and acquisition of manufacturing and test equipment.
- Troubleshoot processes that do not meet expected results.
- Coordinate with Supplier Quality to ensure Northrop Grumman standards are followed for externally manufactured components.
Other
- Ability to obtain and maintain a DoD Secret clearance
- U.S Citizenship is required.
- Ability to work independently and under tight schedule constraints to deliver quantifiable results with documented recommendations for when to establish new processes.
- Ability to read and understand established processes while looking for opportunities for existing process improvement to increase output while decreasing costs.
- Experience working with external suppliers.
