Semiconductor Foundry Interface Engineer Jobs (NOW HIRING)

Location: San Diego, CA, US

This position is responsible for the technical aspects of the foundry interface with external SOS, Off the Shelf, and SOI foundry partners. The Senior Staff Foundry Engineer will drive and lead projects related to sustaining fab processes.

• Maintain and sustain custom and off‑the‑shelf technologies for pSemi and muRata at our foundry partners. Serve as the technical owner for governance of DRC and manufacturability inquiries, issue triage, escalation, and closure across design, CAD, and manufacturing stakeholders.
• Lead yield and quality excursions at the foundry (containment, root cause, corrective and preventive action), partnering with Product Engineering and Customer Quality; drive executive‑ready technical narratives for customer‑impacting events (including RMAs).
• Establish KPIs and reviews for excursion response time, recurring defect prevention, and yield learning transfer across products and technologies.
• Provide foundry and device‑engineering technical leadership for technology development and sustaining, translating process and device learnings into design rules, sign‑off guidance, and reliability and yield guardbands.
• Own the technical change‑control workflow with foundry partners (process changes, PCNs, mask and reticle changes, and wafer‑fab flows), including risk assessment, qualification strategy, and internal release recommendations.
• Mentor engineers to understand device physics and its relationship to product performance.
• Act as the front‑line communication channel for customers and company on any processing, quality, reliability, tapeout, NPI, B2B data and DRC issues related to custom wafer fab processes and off‑the‑shelf wafer fab processes.
• Provide customer engineering support as technical lead on wafer fab‑related issues.
• Engage with CFTs to ensure manufacturing, DRC violations and assembly requirements are met.
• Interact with business units, supply chain, technology development teams, design, NPI and assembly experts to drive next‑generation products with appropriate reticle layout, tapeout requirements, cycle time, fab processing, and capacity.
• Review tapeout floorplan and frame structures to ensure foundry‑related test, assembly and customer requirements are met.
• Manage and drive major fundamental changes to frame and reticle tapeout structures and procedures to accommodate changing assembly and customer product performance needs.
• Lead end‑to‑end foundry transfer programs (qualification strategy, comparability plans, risk mitigation, and readiness reviews), ensuring continuity of yield, reliability, and cycle time for customer commitments.
• Design and implement scalable foundry‑engineering operating processes (intake, prioritization, documentation, and post‑mortems) to improve cycle time, predictability, and cross‑site execution.
• Leverage past expertise with fab processes to ensure new designs and processes capture and utilize lessons learned from past processing, tapeout, technical investigations, and system issues.
• Travel up to 25% (Singapore and Japan).

• 10+ years of experience in semiconductor manufacturing, process development, or foundry technical interface.
• Experience working with deep sub‑micron fab processes and wafer fab organizations based in Asia.
• Key experience interacting with product, technology, design, CAD, NPI, assembly, and supply chain.
• Demonstrated leadership of cross‑functional foundry programs with measurable outcomes (yield, excursion response, cycle time, reliability, or cost).
• Experience driving foundry change‑control and PCNs and qualification decisions using structured risk and data analysis.
• Strong external stakeholder management: leading technical escalations and negotiating technical trade‑offs with foundry counterparts.
• Hands‑on understanding of tapeout readiness: DRC and DFM methodology, mask and reticle considerations, and manufacturing constraints.

• BS & 10‑12 years experience.
• MS & 7‑10 years experience.
• Ph.D. & 5‑7 years experience.
