Summary
👤
Senior🎓
Top SchoolLijian Liu is a seasoned software engineering leader with 8+ years in senior management roles and over two decades of hands-on engineering experience, currently serving as Senior Manager II at Walmart in Cupertino. He has led large-scale observability, logging, and storage initiatives at Amazon (including architecting one of the largest Elasticsearch ingest systems and launching UltraWarm) and built real-time tooling and data lake solutions at AWS. Known for turning complex distributed systems into operationally excellent, on-call-ready services, he blends deep systems architecture with people leadership—hiring, mentoring, and growing teams into product owners. His background spans infrastructure, platform, and developer-facing tooling across Microsoft, Sendmail, and early embedded/driver work, giving him rare end-to-end expertise from kernel drivers to cloud-scale services. He believes “code can change the world,” and has repeatedly converted that conviction into production systems that process billions of records daily. An interesting detail: he named an API version at Amazon (20160207) and won Amazon’s “Just Do It” award for impact beyond his role.
