At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world. 

The Advanced Products Center (APC) Manufacturing Engineering organization is seeking a Principal SMT Process Engineer to join the CCA Process Engineering team in McKinney, Texas. This hands-on role operates in a fast-paced, collaborative cleanroom environment, supporting RF microelectronic packaging and surface mount technology (SMT) within our state-of-the-art Microwave Automated Factory (an ISO Class 8 cleanroom environment). As subject matter experts, our team plays a critical role in factory success by installing and qualifying new equipment, improving existing processes, and driving process improvement projects. You will work closely with product engineers, quality engineers, reliability engineers, tooling engineers, industrial engineers, and operations leaders to develop and implement cutting-edge materials, processes, and automation, while also supporting mature production processes.

Responsibilities include evaluating materials, equipment, and processes through statistical process control, experimental design, material analysis, mechanical design analysis, and root cause analysis. This role involves qualifying equipment, conducting acceptance testing, and developing specifications, as well as collaborating with internal and external suppliers to resolve technical challenges. Every day brings new opportunities to solve unique problems, making this a dynamic and impactful position.

We are specifically seeking candidates who are hands-on, enjoy diving deep into technical requirements, proactive, accountable, good communicators, adaptable in a fast-paced environment, experienced in automated manufacturing, and ready to solve unique problems daily. This is an exciting opportunity to make a meaningful impact on innovative technologies and production processes.

What You Will Do

• Provide on-site support for high-volume, high-mix production, addressing factory equipment, processes, materials, and product challenges to ensure efficient operations

• Work hand-in-hand with product engineers, quality engineers, reliability engineers, and manufacturing engineers on product manufacturing

• Develop and implement materials, processes, process improvements, and production support using established statistical process control techniques, experimental designs, material analysis, mechanical design analysis, and root cause analysis

• Evaluate materials, equipment and processes (including qualification, acceptance testing, and specification development) and interface with key internal and external suppliers to resolve technical issues

• Lead development, optimization and control of Surface Mount Technology (SMT) processes including paste deposition, paste and epoxy dispensing, pick-and-place, reflow and inspection (SPI, AOI and Xray)

• Drive yield improvements initiatives using data analysis, Design of Experiments (DOE) and root cause methodologies

• Collaborate with Design and Product Engineers to provide Design for Manufacturability (DFM) feedback and ensure robust product designs

• Support new product builds, often using automated equipment, and develop innovative solutions for next-generation product designs

• Drive process improvement projects to enhance factory productivity by integrating new technologies, qualifying new materials, and optimizing workflows

• Evaluate materials, equipment and processes (including qualification, acceptance testing, and specification development) and interface with key internal and external suppliers to resolve technical issues

• Evaluate, select, and integrate capital equipment to meet both current production demands and future business needs

• Communicate technical information effectively across cross-functional teams to ensure alignment an
