Psemi Jobs (NOW HIRING)

pSemi Corporation is a Murata company driving semiconductor integration. pSemi builds on Peregrine Semiconductor’s 30-year legacy of technology advancements and strong IP portfolio but with a new mission—to enhance Murata’s world‑class capabilities with high‐performance semiconductors. With a strong foundation in RF integration, pSemi’s product portfolio now spans power management, connected sensors, optical transceivers, antenna tuning and RF frontends. These intelligent and efficient semiconductors enable advanced modules for smartphones, base stations, personal computers, electric vehicles, data centres, IoT devices and healthcare. From headquarters in San Diego and offices around the world, pSemi’s team explores new ways to make electronics for the connected world smaller, thinner, faster and better.

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

• Maintain and sustain custom and off‑the‑shelf technologies for pSemi and Murata at our foundry partners. Serves 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.
• Mentoring engineers to understand device physics and its relationship to product performance.
• Front line communication channel for customer and company communication for any processing, quality, reliability, tapeout, NPI, B2B data and DRC issues on custom wafer‑fab processes and off‑the‑shelf wafer‑fab processes.
• 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, 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 learnt from past processing, tapeout, technical investigations and system issues.
• Travel up to 25% (Singapore and Japan).

• 10+ Years of experience including semiconductor manufacturing, process development, or foundry technical interface.
• Experience working with deep sub‑micron fab processes, wafer‑fab organisations based in Asia.
• Key experience interacting with product, technology, design, CAD, NPI, assembly, 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
