Quality Process Engineer - Semiconductor Manufacturing

Location: Colorado Springs (Onsite)

Our Team:

Semtech Corporation (NASDAQ:SMTC; ) is a leading supplier of high-quality analog and mixed-signal semiconductor products. Semtech is an organization headquartered in Camarillo, California with 31 offices in 14 countries around the world.

Semtech’s Protection Business Unit is a group of passionate and talented individuals tasked to support the development of industry-leading protection integrated circuits (IC) for high performance analog and mixed-signal semiconductor for high‑end consumer, automotive and industrial end market applications, dedicated to providing customers with high quality proprietary solutions and breakthrough technology.

We are seeking an experienced Quality Engineer with chip-scale packaging (CSP) and semiconductor backend assembly expertise to support our wafer‑level and flip chip manufacturing operations. This role combines hands‑on quality engineering with supplier quality management, focusing on process qualification, device characterization, corrective action leadership, and new product introduction (NPI). The ideal candidate brings deep technical knowledge of semiconductor packaging processes, proven ability to drive quality improvements through data‑driven problem‑solving, and skill in building collaborative relationships across engineering, manufacturing, and supplier organizations.

This is a permanent, full‑time position offering the opportunity to directly impact product quality and manufacturing excellence in a high‑reliability semiconductor environment.

• Support qualification and validation of chip‑scale packaging processes including flip chip, wafer‑level CSP, die attach, molding, and plating operations
• Conduct statistically rigorous device characterization across process, voltage, and temperature (PVT) conditions to verify performance margins and detect reliability risks
• Design and execute Design of Experiments (DOE) to optimize packaging process parameters, identify critical factors, and improve process robustness
• Apply Statistical Process Control (SPC) methodologies to monitor critical process parameters and process capability (Cpk/Ppk) for packaging operations
• Perform Measurement System Analysis (MSA) and Gage R&R studies to validate inspection and test equipment capability
• Support new product introduction (NPI) through process validation (IQ/OQ/PQ), first article inspection (FAI), and production readiness activities
• Develop and maintain Process FMEAs (pFMEA), Control Plans, and process documentation for packaging operations
• Investigate and resolve quality issues related to packaging processes including solder joint integrity, die cracking, underfill defects, warpage, and assembly yield

• Lead corrective action reports (CARs) using 8D methodology and structured root cause analysis (5-Why, fishbone, fault tree analysis)
• Partner with engineering and manufacturing teams to close open CARs through collaborative problem‑solving, ensuring root causes are properly addressed and corrective actions are effective
• Facilitate cross‑functional failure analysis and multi‑factor experiments to identify process sensitivities and root causes
• Track CAR closure progress and provide status reporting to Quality Director and site leadership
• Verify effectiveness of implemented corrective actions through data analysis and follow‑up validation
• Support continuous improvement initiatives using Lean/Six Sigma methodologies and DMAIC problem‑solving

• Manage supplier non‑conformances (SCARs), corrective actions, and performance improvement initiatives
• Coordinate with suppliers on process change notifications (PCNs), engineering changes, and qualification requirements
• Support supplier business reviews monitoring SPC data, yield trends, and reliability metrics

• Support maintenance of ISO 9001 quality management system and transition to IATF 16949 automotive standards
• Participate in internal audits and external certification activities as technical subject matter expert
• Review and approve quality documentation…
