ROLE
As an Astera Labs Principal Lab Validation Engineer, you will take a hands-on role to find the root cause of any customer quality concerns and develop corrective actions. You will:
- Directly root-cause failures to the circuit, package, firmware, or protocol-level interactions. Collaborate with design, validation, and system engineering teams as needed.
- Modify device firmware to test out engineering theories leading to potential fixes or production screens.
- Investigate failures such as link training issues, lane margining failures, eye closure, jitter sensitivity, protocol errors, and interoperability problems.
- Debug retimer specific failures, including pass-through path issues, clock forwarding problems, equalization settings, and link bring-up reliability.
- Analyze high speed link failures, including lane mapping, bifurcation errors, hot-plug issues, compliance test failures, and error propagation across multiple ports.
- Use advanced lab instrumentation (BERT, high-bandwidth oscilloscopes, protocol analyzers, VNAs, TDR, spectrum analyzers) to characterize and isolate failures.
- Develop and run stress tests and margining experiments to identify weak design or process corners.
- Provide feedback on system-level integration challenges for retimers and PCIe switches (e.g., board layout, equalization tuning, firmware interactions).
- Drive physical failure analysis to isolate and image defects using methods such as fault isolation, probing, de-processing, FIB, thermal/voltage stress testing.
- Document debug findings, propose design/process/test improvements, and contribute to FA methodologies.
- Participate in new product development process to ensure readiness for customer returns before products are launched. Collaborating in the development of evaluation hardware (boards and sockets, including FA friendly sockets) and scripts.
BASIC QUALIFICATIONS
- Minimum of a Bachelor’s in Electrical Engineering while a Master’s degree is preferred.
- Minimum of 10 years relevant experience of which 5 years’ is hands-on mixed high-speed lab experience working with equipment such as protocol analyzers, BERT, real-time scopes, sampling scopes, TDR, and VNA.
- Python programming.
- Deep understanding of PCIe protocol (up through Gen6), retimer architecture, and SerDes signal integrity.
- Hands-on experience debugging retimers (equalization tuning, pass-through mode, clocking, reset/link sequencing).
- Hands-on experience debugging PCIe switches (lane bifurcation, hot-plug, multi-port link stability, compliance failures).
- Strong background in NRZ/PAM4 architectures, investigating issues with jitter, CDR/PLL behavior, equalization (DFE, CTLE, FFE), crosstalk, and power integrity.
- Experience in post-silicon validation and bring-up of high-speed PHYs or retimers.
- Solid problem-solving and analytical skills with ability to narrow down complex multi-layer failures.
- Strong written and verbal communication skills.
PREFERRED QUALIFICATIONS
- C (not C++).
- Experience with optics.

- ATE (Automated Test Equipment) Advantest V93K.
- Understanding of system-level architecture for servers, storage, and AI/ML platforms where PCIe retimers/switches are deployed.
LOCATION
Based in San Jose, this position requires an in-person presence, offering a unique opportunity to impact our global operations directly.
COMPENSATION
- Base salary range is $195,000 USD - $235,000 USD. Your base salary will be determined based on your location, experience, and the pay of employees in similar positions.
We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.

Get Access To All JobsTips for Finding Validation Engineer Jobs at Astera Labs Jobs
Tailor your resume to silicon validation workflows
Astera Labs hires validation engineers to test PCIe, CXL, and high-speed interconnect silicon. Frame your resume around pre-silicon verification, post-silicon debug, or hardware bring-up experience rather than generic embedded or firmware work.
Verify your degree field before applying
H-1B eligibility for Validation Engineer roles requires a degree in a specialty field like electrical engineering or computer engineering. A general computer science degree can work, but be ready to document how your coursework directly maps to hardware validation.
Target roles that mention CXL or PCIe protocols
Astera Labs builds connectivity chips for AI and cloud infrastructure. Job postings that name specific protocols signal active headcount, not backfill. Use Migrate Mate to filter open Validation Engineer positions at Astera Labs by these technical signals before applying.
Ask about LCA filing timelines during interviews
Your employer must file a certified Labor Condition Application with the DOL before USCIS can process an H-1B petition. Ask the recruiter whether the LCA is filed before or after your start date is confirmed so you can plan your OPT or grace period accordingly.
Align your OPT end date with Astera Labs hiring cycles
Semiconductor companies like Astera Labs ramp hiring ahead of product tape-outs and platform launches. If your F-1 OPT expires mid-cycle, cap-gap protections extend your work authorization through September 30 if your H-1B petition is filed by April 1.
Prepare validation-specific work samples before negotiating offers
Astera Labs conducts technical screens that go deep on test plan development, failure analysis, and lab equipment experience. Having concrete examples of validation coverage reports or silicon debug logs ready speeds up the offer stage and strengthens your case for sponsorship commitment.

Find Validation Engineer at Astera Labs JobsFrequently Asked Questions
Does Astera Labs sponsor H-1B visas for Validation Engineers?
Yes. Astera Labs has an active history of sponsoring H-1B visas for Validation Engineer roles. The company operates in semiconductor and connectivity hardware, where international engineering talent is central to hiring. If you're on F-1 OPT or another status and have a qualifying electrical or computer engineering background, Astera Labs is a realistic H-1B sponsor to target.
How do I apply for Validation Engineer jobs at Astera Labs?
You can browse and apply for open Validation Engineer positions at Astera Labs directly through Migrate Mate, which tracks sponsorship-friendly roles and filters by visa type. Astera Labs posts roles focused on PCIe, CXL, and high-speed interconnect validation. Applications typically move through an initial recruiter screen, a technical phone interview, and a multi-stage lab or systems interview panel.
Which visa types does Astera Labs commonly use for Validation Engineers?
Astera Labs sponsors across multiple visa categories for this function. H-1B is the most common path for candidates transitioning off F-1 OPT. TN visas are an option for Canadian and Mexican nationals with qualifying engineering degrees. For longer-term employment, Astera Labs also supports EB-2 and EB-3 Green Card sponsorship through the PERM labor certification process filed with the DOL.
What qualifications does Astera Labs expect for Validation Engineer roles?
Most Astera Labs Validation Engineer postings expect a bachelor's or master's degree in electrical engineering, computer engineering, or a closely related field. Hands-on experience with PCIe or CXL protocol testing, logic analyzers, oscilloscopes, and scripting languages like Python is commonly required. Post-silicon debug experience and familiarity with test plan development strengthen an application significantly.
How do I plan my timeline if I need H-1B sponsorship to work at Astera Labs?
H-1B cap-subject petitions must be filed by April 1 for an October 1 start date. If you're on F-1 OPT, cap-gap coverage bridges the gap if your OPT expires between April 1 and September 30. Build backward from the April 1 deadline: USCIS registration opens in March, so you need an offer and a completed Labor Condition Application certified by the DOL before that window opens.
