Role Overview 

As a Tech Lead Engineer, Design Verification, you will define and deliver robust verification for next-generation connectivity silicon that enables rack-scale AI infrastructure. You will partner closely with RTL, architecture, firmware, and post-silicon teams to build verification strategies that prove complex switching behavior across high-bandwidth protocols and demanding system environments. 

Within CCE2, you will lead meaningful verification challenges from planning and testbench architecture through coverage closure and silicon learning. You will contribute to Astera Labs’ hyper-growth mission by helping deliver highly reliable PCIe and UALink connectivity products that keep AI accelerators, memory, and compute resources operating at scale. 

Key Responsibilities 

• Verification Strategy and Planning 

• Develop block- and subsystem-level verification plans from specifications, architecture, and design requirements. 

• Define test scenarios, coverage models, checkers, assertions, and scoreboards for complex switching functionality. 

• Review designs and verification plans with architecture and RTL teams to identify corner cases early. 

• Lead verification planning and execution for assigned features, tracking risks, milestones, and quality metrics. 

• Environment Development and Execution 

• Build and enhance reusable UVM-based SystemVerilog testbenches, agents, sequences, monitors, and reference models. 

• Create directed, constrained-random, and power-on-reset scenarios spanning PCIe Gen 6/Gen 7, UALink, and UCIe behavior. 

• Debug simulation failures using waveform analysis, logs, assertions, and cross-functional collaboration. 

• Partner with RTL and firmware teams to refine interfaces, improve observability, and resolve functional issues. 

• Coverage, Quality, and Silicon Readiness 

• Drive functional and code coverage analysis, identify verification gaps, and close coverage to agreed milestones. 

• Develop regression strategies and automation to improve test quality, turnaround time, and failure triage. 

• Partner with design and post-silicon teams on issue isolation, root-cause analysis, and silicon bring-up readiness. 

• Communicate verification status, risks, and recommendations to technical stakeholders and project leadership. 

Basic Qualifications 

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related technical field. 

• 5–8 years of experience in design verification for complex ASICs or SoCs. 

• Hands-on experience with SystemVerilog and UVM-based verification environments. 

• Experience developing verification plans, testbenches, assertions, scoreboards, and functional coverage models. 

• Familiarity with simulation, waveform-debug, regression, and coverage tools. 

• Strong technical leadership, debugging, commun...
