Tech Lead STA Engineer

Location - Hyderabad

Experience - 6-14 years

Astera Labs is hiring a Principal Engineer, Static Timing Analysis to own top-level timing closure and signoff for our next-generation connectivity silicon powering rack-scale AI infrastructure. In this role, you'll drive full-chip STA strategy across advanced process nodes, partner with physical design, RTL, DFT, and CAD teams, and ensure first-pass timing success on some of the most complex SoCs in the industry.

This is a high-impact technical leadership role at a hyper-growth company purpose-built for AI connectivity. Your work directly enables the PCIe, CXL, UALink, and Ethernet platforms that hyperscalers depend on — and you'll have the ownership, influence, and tooling to do the best work of your career.

• Full-Chip STA Signoff & Timing Closure

• Own end-to-end top-level STA signoff across multiple modes, corners, and operating conditions (MMMC) for complex AI connectivity SoCs

• Drive timing convergence on advanced process nodes (5nm/4nm/3nm and below) from early floorplan through tapeout

• Analyze and resolve setup, hold, recovery/removal, and clock-domain crossing (CDC) timing violations at the chip level

• Methodology & Flow Development

• Define and evolve STA methodology, constraints (SDC) strategy, and signoff criteria across the organization

• Develop and automate flows using PrimeTime, PrimeTime SI, and related signoff tools for crosstalk, noise, and IR-aware timing

• Establish best practices for hierarchical STA, ETM/IPXACT model generation, and budgeting across blocks

• Cross-Functional Technical Leadership

• Partner with Physical Design, RTL, DFT, CAD, and Package teams to drive timing-aware design decisions from architecture through tapeout

• Review and sign off on block-level timing handoffs, ensuring consistency between block and top-level closure

• Collaborate with low-power design teams on UPF/CPF, multi-voltage, and clock-gating timing implications

• Mentorship & Technical Strategy

• Mentor STA engineers and review timing reports, ECOs, and signoff collateral

• Drive root-cause analysis of silicon timing issues and feed learnings back into methodology

• Influence tool selection, EDA vendor engagements, and STA roadmap for future products
