The Quality team at our Colorado Springs backend assembly site manages ISO 9001 certification and IATF 16949 transition, supporting chip-scale packaging operations including flip chip, wafer-level CSP, die attach, molding, and plating processes. We handle internal and external audits, process characterization, document control, and calibration - supporting two manufacturing sites and more than 1,000 controlled documents.

Job Summary:

We are seeking an experienced Quality Process Engineer with chip-scale packaging (CSP) expertise to drive corrective action closure and technical problem-solving across our Colorado Springs backend assembly operations. This role sits at the intersection of quality engineering and process engineering - combining deep technical knowledge of semiconductor packaging with structured problem-solving to eliminate chronic open corrective actions.

You will apply your CSP technical expertise to lead root cause investigations on flip chip, die attach, molding, and plating processes, partnering closely with process engineering, operations, maintenance, and systems engineering teams to diagnose recurring issues and deliver durable solutions. Your technical credibility in semiconductor packaging will enable you to influence cross-functional teams, facilitate collaborative problem-solving sessions, and ensure corrective actions address true root causes rather than symptoms.

Over time, this role may also contribute to quality system auditing as the team scales. If you thrive on applying deep technical knowledge to untangle complex manufacturing problems, influencing engineering teams through data-driven persuasion, and bringing order to ambiguity, this is your role.

Responsibilities:

Corrective Action Leadership (50%)

• Own and drive closure of 70+ open corrective action reports (CARs) across engineering, operations, maintenance, and systems engineering through technical problem-solving and cross-functional collaboration
• Lead cross-functional CAR review sessions, bringing together relevant stakeholders to solve problems comprehensively rather than superficially
• Apply 8D methodology, 5-Why, fishbone, and fault tree analysis combined with CSP technical knowledge to identify true root causes in packaging processes
• Design and execute Design of Experiments (DOE) to identify root causes of process variability and validate corrective actions
• Track CAR closure progress and provide regular status reporting to Quality Director and site leadership
• Verify effectiveness of implemented corrective actions through statistical analysis and follow-up validation
• Identify systemic patterns across open CARs to prioritize high-impact interventions and prevent recurrence

Chip-Scale Packaging & Process Quality (40%)

• Support qualification and validation of chip-scale packaging processes including flip chip, wafer-level CSP, die attach, molding, and plating operations
• Investigate and resolve quality issues related to packaging processes including solder joint integrity, die cracking, underfill defects, warpage, and assembly yield
• 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
• Conduct device characterization and reliability testing to support process optimization and validation

Quality Systems & Supplier Quality (10%)

• Support maintenance of ISO 9001 quality management system; contribute to IATF 16949 automotive standards transition

• Participate in internal and external audits as technical subject matter expert; audit ownership capability is a plus
• Review and approve quality documentation including procedures, work instructions, and process specifications
• Manage supplier non-conformances (SCARs) and corrective action follow-through as needed

Minimum Qualifications:

• Bachelor's degree in Engineering, Materials Science, Physics, or related technical field
• 5+ years of quality engineering experience in semiconductor backend assembly or microelectronics packaging
• Direct hands-on experience with chip-scale packaging technologies including flip chip, wafer-level CSP, or advanced packaging processes
• Demonstrated expertise in 8D methodology, root cause analysis (5-Why, fishbone, fault tree), and structured problem-solving
• Strong statistical analysis skills including SPC, process capability (Cpk/Ppk), hypothesis testing, and Design of Experiments (DOE)
• Working knowledge of AIAG Core Tools: PFMEA, Control Plans, MSA, PPAP, and APQP
• Experience with ISO 9001 or equivalent quality management systems
• Proficiency with statistical analysis software (Minitab, JMP, or equivalent) and Microsoft Office suite
• Excellent written and verbal communication skills with ability to influence across organizational levels
• Proven track record of building collaborative relationships with engineering, manufacturing, and supplier organizations

Desired Qualifications:

• Master's degree in Materials Science, Engineering, or related technical field
• Six Sigma Green Belt or Black Belt certification
• Certified Quality Engineer (CQE) or Certified Quality Auditor (CQA) from ASQ
• ISO 9001 or IATF 16949 Lead Auditor certification
• Experience with wafer fabrication processes (etch, PVD, lithography, thin films) to support packaging integration
• Direct experience with flip chip bumping, redistribution layer (RDL) processes, or advanced wafer-level packaging
• Supplier quality experience with OSATs (Outsourced Semiconductor Assembly and Test) or foundries
• Familiarity with automotive (IATF 16949), aerospace (AS9100), or medical device (ISO 13485) quality standards
• Experience with reliability testing including temperature cycling, HAST, HTOL, and failure analysis techniques
• Knowledge of semiconductor metrology and characterization techniques (SEM, X-ray, C-SAM, profilometry)
• Advanced DOE expertise including fractional factorial, response surface methodology, and Taguchi methods
• Experience with MES systems and quality data management platforms
