Principal SerDes Bring-up Validation Engineer 

Role Overview

Astera Labs is seeking a Principal SerDes Bring-up Validation Engineer to join a cutting-edge mixed-signal design team and lead end-to-end post-silicon bring-up, validation, and characterization. You will own bring-up and characterization strategies from the ground up, translating design and product requirements into measurable test objectives, pass/fail criteria, and schedules, and driving hands-on lab work to verify silicon against specification and performance targets.

As a hyper-growth company building the purpose-built connectivity that powers rack-scale AI infrastructure, the speed and rigor of our silicon validation directly shape what we can ship. You will partner closely with AMS design, firmware, and system teams to build automated test frameworks, debug complex analog and digital interactions at the physical layer, and deliver clear, data-driven recommendations that influence product direction. This is a high-impact role for a deep technical expert who thrives on hands-on problem solving and mentoring across disciplines.

Key Responsibilities 

• Design, develop, and execute bring-up plans. Own end‑to‑end post‑silicon bring up and characterization strategies, translating design/product requirements into measurable test objectives, pass/fail criteria, and schedules. 

• Drive design reviews and specification alignment. Participate in architecture and design‑spec reviews to ensure testability, trace requirements to verification plans, and influence design tradeoffs to meet performance and reliability targets. 

• Lead hands‑on test execution and bring‑up. Perform silicon block level bring‑up, functional and parametric testing, interop checks, and performance benchmarking; rapidly iterate on test flows to accelerate time‑to‑data.
