The Raytheon Capacity Growth Office (CGO) is seeking a Principal Manufacturing Systems Integration Engineer to play a key technical role in deploying, integrating, and validating the manufacturing capabilities required to create production capacity across CGO programs. This position is focused on manufacturing optimization, hands-on implementation, and the technical integration of processes, workflows, tooling, instructions, and supporting systems to ensure factory readiness and performance.

Technical Problem Solving & Constraint Characterization

Identify and characterize manufacturing constraints related to cycle time, variability, flow breaks, material movement, operator workload, or process capability.

Lead and participate in cross-functional problem-solving efforts to eliminate systemic barriers to capacity creation.

Develop and execute practical corrective action plans using data, engineering principles, and on-the-floor validation.

Verify that implemented solutions measurably improve flow, yield, takt adherence, or throughput.

Production System & Manufacturing Capability Integration

Implement improvements that enhance throughput, stabilize workflow, and increase capacity, including takt strategy adjustments, refined work instructions, optimized layouts, and upgraded tooling.

Translate manufacturing readiness needs into actionable technical requirements for processes, tooling, instructions, layouts, and production workflows.

Support deployment, setup, and prove-in of new or enhanced manufacturing capabilities across CGO programs.

Conduct hands-on readiness activities such as dry runs, pilot builds, workstation trials, and characterization builds to validate process capability, flow integrity, operator effectiveness, and production reliability.

Identify bottlenecks and constraints through process observation, data analysis, modeling, and cross-functional engagement, ensuring corrective actions align with Lean principles, operator-centered design, safety, and takt objectives.

Cross-Functional Technical Tasking for Capacity Creation

Serve as an integration point across functions, driving multi-disciplinary execution tasks needed to stand up or expand factory capacity.

Support readiness events, pilot builds, and go-live activities by coordinating technical inputs across engineering, operations, quality, supply chain, and CGO.

Troubleshoot emergent issues and drive rapid resolution to protect schedule, readiness, and flow.

Identify and escape risks to manufacturing readiness, collaborating with stakeholders to drive resolution paths and mitigation strategies.
