Job description

Essential Functions/Major Responsibilities:

• Serve as the primary subject matter expert for semiconductor backend test operations within the product team, applying deep product-engineering experience to guide the development of prescriptive analytics solutions
• Review and validate the recommendations generated by the product, applying domain judgment to confirm they are correct and appropriate before they are acted upon by customer engineers
• Partner with engineering and product teams to define requirements, validate models, and refine recommendation logic based on real-world test-floor behavior, equipment characteristics, and yield/excursion modes
• Distinguish equipment-related contributions to yield, UPH, and uptime loss from process-related causes, translating that analysis into actionable product and engineering insights
• Engage directly with customers at their sites to ensure effective deployment, adoption, and utilization of the product
• Guide customers in integrating prescriptive Test Operations capabilities into their existing production and dispositioning workflows
• Serve as a trusted technical advisor to customers and act as the voice of the customer within the product team
• Support pre-sales activities including demonstrations, proof-of-concept engagements, and technical evaluations

Working Relationships:

This is a senior individual-contributor role with no direct reports. You will work within a matrixed team spanning Product, Engineering, and Customer Success, influencing cross-functional stakeholders to align on product direction and commercialization objectives, and acting as the on-the-ground link between our customers in the Philippines and the product organization.

Qualifications:

Education

Bachelor’s degree in Engineering, Computer Science, or a related field (advanced degree preferred).

Required Knowledge, Skills, and Abilities

• 5+ years of experience as a product engineer (test product engineer) or equivalent role at a semiconductor IDM or OSAT
• Hands-on experience with semiconductor backend test — test program characterization, yield analysis, test-data disposition, and the behavior and failure modes of test equipment (handlers and testers)
• Deep understanding of the day-to-day product-engineering decisions this product is designed to support and automate, such as dispositioning yield and test excursions and determining equipment-versus process-related causes
• Strong ability to translate technical domain knowledge into actionable product and engineering insights, and to exercise sound judgment when validating automated recommendations
• Familiarity with test-floor metrics such as yield, UPH/throughput, and equipment uptime, and how they combine into effective output (good units per shift)
• Comfortable with customer-facing work including on-site visits, training, and process consultation
• Excellent communication skills; able to bridge engineering teams and customer operations
• Based in the Philippines, with willingness to travel regularly within the region and occasionally internationally
