Senior SMT Process Engineer for RF Manufacturing

Raytheon; McKinney (TX); On-site; USD 107,500 - 204,500; Full time

Job summary

Raytheon seeks a Principal SMT Process Engineer for the McKinney, TX facility. The role supports high-volume, high-mix production in an ISO Class 8 cleanroom, focusing on SMT process development and manufacturing improvements.

You will collaborate with design and product engineers, perform DOE studies, qualify equipment, and drive yield and process improvements across SMT lines. The position is onsite with a day shift and potential 9/80 schedule.

Qualifications

• Typically requires a Bachelor's degree in Science, Technology, Engineering or Math (STEM) and a minimum of 8 years of prior relevant experience.
• 5+ years of experience in Surface Mount Technology (SMT) Manufacturing/Process Engineering
• Experience with high reliability manufacturing environments (aerospace, defense, medical, automotive).

Responsibilities

• 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 SPC 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 SMT processes including paste deposition, paste and epoxy dispensing, pick-and-place, reflow and inspection (SPI, AOI and Xray).
• Drive yield improvement 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, 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 and successful execution of initiatives.
• Mentor and coach junior engineers and technicians; act as a subject matter expert (SME).
• Spend up to 6+ hours per day in a cleanroom environment, adhering to cleanroom protocols and electrostatic discharge (ESD) procedures.
• Work primarily during the day shift (start time between 6 AM and 9 AM) with the potential for a 9/80 schedule (9 days over 2 weeks).
