- Develop and maintain engineering plans and schedules, manage technical risks, and coordinate deliverables to support program objectives.

- Ensure complete and accurate definition of mechanical assembly components, subsystems, and ground support equipment within the Technical Data Package (TDP).

- Lead technical peer reviews and drive resolution of complex engineering issues.

- Serve as a primary technical interface with the design agent and Industry IPT, coordinating technical activities and driving alignment on engineering decisions and issue resolution.

- Work with the design agent to incorporate design changes that enhance manufacturability, quality, and production efficiency.

- Collaborate with manufacturing engineering, operations, and liaison engineering to resolve production bottlenecks, improve processes, and support hardware delivery.

- Coordinate with supplier program managers to ensure timely hardware delivery, resolve technical issues, and support supplier producibility improvements.

- Provide technical oversight of nonconforming hardware dispositions within established MRB authority and support Root Cause and Corrective Action (RCCA) investigations.

- Lead the Failure Review Board (FRB) process to resolve technical issues.

- Identify, assess, and communicate program risks and improvement opportunities to the Risk and Opportunity (RIO) Board.

- Serve as a senior technical representative to the customer, providing program status updates and communicating engineering and manufacturing activities.

- Mentor less experienced engineers and provide technical guidance across the IPT.

**Basic Qualifications**

- Bachelor's degree in engineering from an ABET-accredited institution with 12+ years of relevant experience.

- Demonstrated experience leading multidisciplinary engineering teams or Integrated Product Teams (IPTs) responsible for complex mechanical subsystem design, development, integration, or production.

- Experience planning and coordinating engineering activities, managing technical deliverables, and addressing program risks and schedules.

- Proficiency with CAD tools such as Creo, CATIA, AutoCAD, or SolidWorks.

- Experience working within Product Lifecycle Management (PLM) environments.

- Working knowledge of GD&T (ASME Y14.5) and tolerance stack-up analysis.

- Understanding of engineering drawings, specifications, and configuration management processes.

- Experience leading technical investigations and resolving complex engineering issues in development or production environments.

- Demonstrated ability to lead technical reviews and make sound engineering recommendations.

- Understanding of cost, schedule, and technical risk impacts associated with engineering decisions.

- Experience interacting directly with customers and external engineering organizations to coordinate activities and resolve technical issues.

- Excellent communication, leadership, and problem-solving skills, with the ability to work independently and mentor other engineers. Proficiency with Microsoft Office applications (Word, Excel, PowerPoint).

**Preferred Qualifications**

- Active security clearance.

- Experience supporting DoD programs related to missile systems, reentry vehicles, or hypersonic technologies.

- Prior technical leadership experience in the design, development, qualification, or integration of missile system mechanical subsystems.

- Experience coordinating technical activities with external design agents, suppliers, and industry partners.

- Experience supporting rapid development, prototyping, or fast-paced engineering programs.

- Familiarity with AS9100 aerospace quality management systems.

- Knowledge of MIL-STD-31000 Technical Data Package (TDP) development, engineering release processes, and configuration control.

- Experience creating and reviewing engineering drawings and complex CAD assemblies using PTC Creo and managing engineering data within Windchill.

- Experience supporting Material Review Board (MRB), Failure Review Board (FRB), and Root Cause and Corrective Action (RCCA) processes.
