Role Overview
Astera Labs is seeking a Senior Principal Digital Design Engineer to drive the architecture and implementation of next-generation digital designs powering AI infrastructure connectivity. This is a high-impact technical leadership role where youll define micro-architecture strategies for better power, performance and area tradeoff, own complex chip-level design decisions, and guide multiple blocks from concept through silicon bring-up for industry-leading products supporting PCIe Gen 6/7, CXL, UALink, UCI, Ethernet, and DDR4/DDR5 protocols.
As a senior technical leader, youll shape design methodologies, mentor engineering teams, and collaborate cross-functionally with verification, physical design, DFT, and post-silicon teams to deliver high-performance, production-quality silicon. Youll also influence roadmap decisions and drive design excellence across the organization, ensuring Astera Labs continues to set the standard for AI connectivity solutions.
Key Responsibilities
Architecture & Technical Leadership
Define and drive micro-architecture for complex digital blocks and subsystems across multiple product lines
Establish architectural standards and best practices that scale across the design organization
Provide technical guidance and decision-making on critical design trade-offs impacting performance, power, and area
Design Execution & Ownership
Lead RTL implementation of complex designs from architecture definition through GDS and silicon bring-up
Drive timing constraints and closure strategies and implement robust Design-for-Test (DFT) methodologies
Own accountability for design quality, schedule, and successful production delivery
Cross-Functional Collaboration
Partner with verification teams to develop comprehensive test plans, achieve coverage closure, and debug complex issues
Collaborate with physical design, DFT, and post-silicon teams to ensure seamless integration and bring-up
Work with firmware and software teams to optimize hardware-software interfaces
Mentorship & Process Excellence
Mentor and develop junior and senior engineers, elevating team technical capabilities
Drive continuous improvement of silicon development processes, CAD automation, and design infrastructure
Contribute to organizational knowledge sharing and technical reviews
Basic Qualifications

12+ years of hands-on experience developing complex SoC/silicon products in Server, Storage, and/or Networking markets
Demonstrated expertise in architecture definition, micro-architecture development, RTL coding, synthesis, and timing closure
Deep knowledge of at least one high-speed protocol: PCIe, CXL, Ethernet, DDR, or similar
Production experience with advanced CMOS nodes (=7nm)
Proficiency with Cadence and/or Synopsys digital design flows
Track record of delivering multiple high-performance designs to production
Preferred Qualifications
Masters degree in Electrical Engineering or related field
Experience with multiple high-speed protocols (PCIe Gen 5/6, CXL, UALink, Ethernet, DDR4/DDR5)
Hands-on collaboration with embedded firmware teams and familiarity with RISC-V or Arm subsystems
Proven contributions to design methodology, CAD automation, or infrastructure improvements
Experience leading technical teams or driving cross-functional initiatives in data center environments
Salary range is $205,000 to $255,000 depending on experience, level, and business need. This role may be eligible for discretionary bonus, incentives and benefits.
