Role Overview Astera Labs is looking for a Principal IP Signoff & Methodology Engineer to own the readiness, quality, and signoff of internal and external IP blocks before they are released into SoC and system implementation flows. This role sits at the intersection of IP development, physical design, and tapeout execution, with responsibility for ensuring that IP deliverables from both external vendors and internal engineering teams are complete, validated, and integration-ready. You will drive signoff closure and revision management across key IP handoff views and verification checks, including RTL, SDC, LEF/DEF, netlists, timing, physical verification, and package-aware considerations such as die and bump views. You will also drive configuration management of digital IP and ensure adherence to Astera-defined specifications, configurations, and usage profiles. The right candidate combines strong digital and physical design fundamentals with disciplined execution, debug ownership, and the ability to partner closely across digital, analog, package, CAD, and integration teams. Key Responsibilities: IP Release Readiness • Own the completeness, consistency, and configuration management of all internal and external IP deliverables, including supported configurations and usage profiles. • Own signoff readiness for IP releases, ensuring all required handoff views and collateral are complete, version-controlled, validated, and integration-ready. • Review and validate key IP deliverables such as RTL, timing constraints (SDC), synthesized netlists, LEF/DEF, floorplan-related data, and supporting documentation. • Define and maintain IP signoff checklists, release criteria, quality gates, and acceptance requirements for reusable IP. • Drive alignment between IP providers and SoC or subsystem implementation teams on expected deliverables, quality metrics, and release timelines. Digital Signoff • Run, review, and validate digital signoff checks for IP releases, including timing, logical consistency, and implementation quality. • Verify the completeness and correctness of RTL, timing constraints, synthesized netlists, and other digital collateral required for downstream integration. • Ensure consistency across RTL, netlist, timing, and physical views prior to IP release. • Analyze digital signoff issues, identify root causes, and drive closure in partnership with design, physical design, and CAD teams. Signoff and Physical Verification • Run, review, and debug physical verification signoff for IP and related assembly views, including DRC, LVS, PERC, and other required physical signoff checks. • Analyze physical verification results, identify root causes, and drive closure of violations in partnership with design, layout, and CAD teams. • Verify consistency across abstract, netlist, physical, and package-related views to support clean downstream integration. • Assess signoff readiness not only at the block level but also in the context of top-level integration,
