The Advanced Products Center (APC) Manufacturing Engineering organization is seeking a Senior 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.

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 and successful execution of initiatives.
• Mentoring and coaching junior engineers and technicians.
• 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).

What You Will Learn

Responsibilities include evaluating materials, equipment, and processes through statistical process control, experimental design, material analysis, mechanical design analysis, and root cause analysis.
