Regression Analysis Jobs in Texas (NOW HIRING)

Primary Responsibilities
Product-Level Technical Ownership
• Own yield, variability, and device performance across all manufacturing stages for assigned products.
• Lead deep technical investigations into complex yield limiters involving epitaxy, wafer processing, device architecture, inspection, and test systems.
• Develop physics-based hypotheses and validate them through structured DOE, statistical modeling, and experimental execution.
• Drive yield recovery plans from problem identification through verified improvement.
• Serve as the central technical authority for product behavior across internal teams and external customers.
Epitaxy & Reactor Expertise
• Leverage strong understanding of compound semiconductor epitaxy and epi reactor fundamentals.
• Understand critical growth parameters including temperature uniformity, V/III ratio, precursor chemistry, chamber pressure, dopant incorporation, thickness control, strain management, and defect formation mechanisms.
• Correlate epitaxial variation to downstream optical and electrical device performance.
• Partner with Epitaxy Engineering to reduce wafer-to-wafer and run-to-run variability.
• Translate device-level failures into actionable feedback for reactor and process optimization.
Advanced Data Analytics & Modeling
• Perform deep dives into large-scale manufacturing datasets using SQL, JMP, Python, or equivalent tools.
• Develop multivariate statistical models to isolate root causes of yield loss.
• Apply regression analysis, variance decomposition, SPC, and DOE methodology.
• Build predictive models for early detection of yield excursions.
• Develop automated data analysis workflows to accelerate technical learning cycles.
• Translate raw data into defensible, physics-based conclusions.
Wafer Process & Device Integration
• Analyze interactions between epitaxy, lithography, etch, deposition, metallization, inspection (AVI), and electrical/optical test steps.
• Identify how upstream variability propagates into final device performance.
• Provide Design-for-Manufacturability (DFM) input during new product development.
• Reduce process sensitivity through structured experimentation and device-level insight.
New Product Introduction (NPI)
• Own yield performance during new product ramp from development into high-volume manufacturing.
• Conduct structured technical risk assessments.
• Rapidly identify and mitigate yield sensitivities during early production.
• Shorten yield learning cycles using disciplined experimentation and data-driven decisions.
Customer & External Technical Engagement
• Serve as a primary technical interface for key customers on yield, device performance, and reliability topics.
• Present complex technical findings clearly and confidently to customer engineering and quality teams.
• Lead technical discussions during customer audits and yield reviews.
• Support joint root cause investigations and corrective action plans.
• Translate internal manufacturing data into customer-relevant performance metrics.
• Build customer trust through clear, physics-based explanations of device behavior and variability.
What Success Looks Like
• Sustained improvement in product yield and variability across the full manufacturing flow.
• Rapid containment and permanent resolution of yield excursions.
• Successful high-yield ramp of new products into volume manufacturing.
• Strong correlation established between epitaxial behavior and device-level outcomes.
• Development of predictive models that prevent yield loss before it occurs.
• Recognition internally and externally as a technical authority on product behavior.
• Earned trust from key customers through technical rigor and consistent performance.
Education & Experience
• PhD in Electrical Engineering, Applied Physics, Materials Science, or related discipline with strong emphasis on semiconductor device physics or relevant experience with Master/B-Eng.
• 5+ years of experience in semiconductor device, product, or yield engineering in high-volume manufacturing.
• Demonstrated history of independently leading complex technical investigations and delivering measurable yield improvement.
• Experience in compound semiconductor or optoelectronic device manufacturing strongly preferred.
Required Technical Skills
• Strong foundation in solid-state physics and semiconductor device operation.
• Working knowledge of compound semiconductor epitaxy and epi reactor operation.
• Understanding of key epitaxial variables including temperature control, V/III ratio, precursor flow stability, pressure control, strain, and dopant incorporation.
• Experience correlating material-level variation to device electrical and optical performance.
• Advanced proficiency in statistical analysis and DOE methodology.
• Proficiency in JMP, Python, R, or equivalent data analysis tools.
• Strong SQL skills for querying large manufacturing databases.
• Experience with SPC, multivariate modeling, regression analysis, and variance decomposition.
• Ability to automate data extraction and analysis workflows.
• Experience presenting technical material to external customers or executive leadership.
• Ability to defend technical conclusions under scrutiny.
Personal Attributes
• Intellectual curiosity and comfort operating in ambiguous technical environments.
• High ownership mindset and accountability for outcomes.
• Ability to challenge assumptions with data and physics-based reasoning.
• Strong cross-functional influence skills.
• Clear and confident communicator in both technical and customer-facing settings.
