About The Role
We are seeking an experienced Lead Machining Manufacturing Engineer to lead CNC machining strategy and advanced tooling initiatives within the Operations Engineering department. This role will act as the technical focal point for machining operations, driving manufacturing excellence through optimized CNC programming, fixture design, tooling strategy, and process improvement.
The successful candidate will play a critical role in improving machining processes to improve efficiency, reducing cycle times, increasing yield, and supporting the manufacture of high-precision components. You will collaborate closely with Design Engineering, Production, Quality, Supply Chain, and Operations teams to develop robust, scalable machining processes capable of supporting both prototype and production environments.
This is a technical leadership role requiring deep expertise in multi-axis machining, CAD/CAM programming, CNC turning, advanced work holding solutions, and manufacturing process optimization.
The Operations Engineering team maintains a technology roadmap to ensure that the business is investing in the correct technology to support our customers' requirements. The Lead Machining Manufacturing Engineer will be responsible for maintaining and adding to the machining section of the technology roadmap.
Key Responsibilities
- Lead CNC machining strategy development across the Operations Engineering department.
- Develop and improve functional operating processes and incorporate them into Lockheed Martin's governing processes.
- Process Ownership: Own, lead and develop the technology roadmap for machining on behalf of the Operations Engineering department ensuring alignment to Engineering requirements and technology developments within industry.
- Develop, optimize, and validate CNC programs for 3-axis, 4-axis, and 5-axis machining centres.
- Develop, optimize, and validate CNC programs for standard and mill turn lathes.
- Design and implement advanced fixturing and work holding solutions to improve repeatability, precision, and throughput.
- Select and optimize cutting tools, tooling strategies, and machining parameters for a wide range of materials and geometries.
- Establish best practices for machining operations, setup reduction, tooling management, and process standardisation.
- Support new product introduction (NPI) activities through Design for Manufacture (DFM).
- Troubleshoot complex machining and tooling issues, implementing corrective and preventive actions.
- Work closely with Quality teams to ensure compliance with engineering tolerances, inspection requirements, and customer standards.
- Develop and maintain manufacturing documentation including setup sheets, tooling lists, process flows, and work instructions.
- Lead continuous improvement initiatives using Lean Manufacturing and Six Sigma methodologies where appropriate.
- Support capital equipment selection, commissioning, and capability validation for new CNC machinery and automation technologies.
- Ensure all machining activities comply with health, safety, and environmental standards.
