Role Overview

As a Principal Quality Engineer at Astera Labs, you will be a key individual contributor driving product and process quality across our semiconductor connectivity product lines. You will own end-to-end quality engineering activities — from new product introduction and process control through field quality and supplier performance — ensuring our products meet the highest reliability and quality standards demanded by the world's leading cloud and AI infrastructure providers.

Key Responsibilities

Product Quality & Reliability: Lead technical investigations of field returns, warranty claims, and reliability failures for semiconductor products; coordinate root-cause analysis (8D, 5-Why, Ishikawa) and drive corrective and preventive actions (CAPA) to closure in partnership with design, validation, and applications engineering teams.
New Product Introduction (NPI): Partner with design, package, and manufacturing teams during NPI to define quality gates, review FMEAs (Design & Process), establish control plans, and ensure product meets qualification and reliability requirements prior to production ramp.
Process Quality & Control: Develop, document, and implement in-process quality controls including Statistical Process Control (SPC), measurement system analysis (MSA), and go/no-go checkpoints to monitor and improve yield and defect rates across manufacturing operations.
Supplier Quality: Support supplier quality activities including conducting supplier audits, tracking supplier scorecards, issuing Supplier Corrective Action Requests (SCARs), and monitoring incoming quality for key semiconductor and substrate suppliers.
Quality Management System (QMS): Contribute to the maintenance and continuous improvement of the ISO 9001 QMS; author and review procedures, work instructions, and audit reports to ensure alignment across the organization.
Data Analysis & Metrics: Define, track, and report key quality KPIs (PPM, DPMO, warranty cost, MTBF, supplier defect rates) to engineering and operations leadership; leverage data-driven insights to prioritize quality improvement efforts.
Cross-Functional Collaboration: Serve as the quality engineering point of contact across design, validation, operations, and customer-facing teams; support Field Application Engineers (FAEs) with technical quality information and ensure customer issues are driven to resolution.
Quality Improvement: Apply Lean, Six Sigma, and other quality improvement methodologies to identify and eliminate waste, reduce variation, and improve overall product reliability and yield.
