Full Job Description
What you Will Do:

New Product Introduction (NPI)
  • Drive end-to-end NPI execution from first silicon through qualification, sampling, and volume production.
  • Define NPI milestones, readiness criteria, and exit conditions across design, test, reliability, manufacturing, and operations.
  • Work closely with silicon design, DFT, test engineering, supply chain, and operations to ensure manufacturable, testable product launches.
  • Identify technical and operational risks early and lead mitigation efforts through data-driven decision making.

Reliability & Qualification
  • Define and execute reliability and qualification strategies for advanced-node coherent DSP ICs, including Known Good Die (KGD) qualification.
  • Develop and own reliability stress plans (HTOL, HTSL, temperature cycling, ESD, latch-up, early-life failure, etc.)
  • Manage external reliability lab execution, including coverage definition, scheduling, reporting, and failure analysis.
  • Analyze qualification data and drive product release readiness based on measured risk and maturity.

Product Quality
  • Define internal product quality targets aligned with application and market requirements.
  • Own quality metrics related to silicon maturity, yield stability, and manufacturing readiness.
  • Drive root-cause analysis for quality or reliability excursions and lead corrective actions.
  • Support customer quality discussions as needed, primarily through preparation of data and technical analysis.

Test, Sampling & Production Ramp
  • Lead technical engagement with foundry and OSAT partners from wafer fabrication through back-end processing and shipment.
  • Define and refine production test strategies with test engineering, balancing coverage, cost, yield, and guard-banding.
  • Drive engineering builds, characterization lots, and production ramps.
  • Ensuring robust handoff from engineering tests flows to stable production manufacturing.

Yield Optimization & High-Volume Manufacturing
  • Own yield learning and yield optimization from early silicon through high-volume manufacturing
  • Perform deep analysis of wafer sort, die sort, and final test data to identify yield limiters.
  • Drive cross-functional corrective actions across design, process, test, and manufacturing.
  • Establish yield targets, dashboards, and regular yield reviews to support sustained volume production.

What you Will Bring:
  • Bachelor's degree in electrical engineering or related fields. Master's degree preferred.
  • 10+ years of experience in product engineering, silicon manufacturing, reliability engineering, or related IC lifecycle roles.
  • Proven experience taking complex ICs from first silicon through qualification and volume manufacturing.
  • Strong background in reliability qualification, stress testing, and failure analysis
  • Experience with wafer-level test, Known Good Die (KGD), and production test flows.
  • Demonstrated success driving yield learning and yield improvement.
  • Strong analytical skills and comfort working directly with large manufacturing and test data sets.
  • Excellent cross-functional collaboration skills with a bias toward technical execution

Salary Range:

$150,000 - $250,000 Base Annually
The final offer will be determined based on job-related skills, experience, qualifications, and location.
