DISTINGUISHED, SOFTWARE ENGINEER at Walmart

Job description

Position Summary... Distinguished Engineer — NoSQL Databases will define and drive the technical vision for nosql databases platforms at a massive scale. This is a senior technical leadership role for an engineer with deep expertise in NoSQL systems, database internals, performance optimization, and production operations. What you'll do... About Team: The Data Services team within Global Technology Platform powers mission-critical data infrastructure across the enterprise, enabling SQL, NoSQL, and messaging services for tens of thousands of deployments across Walmart Global Tech. These platforms support multi-petabyte-scale data, millions of requests per second, and extremely high availability requirements for applications used across Walmart stores, digital channels, supply chain, and internal enterprise systems. The candidate will shape the architecture and evolution of database capabilities across the organization, with a strong focus on Search & Cache systems. You will work on some of the most complex database challenges in the industry including automated scaling, recovery, large scale system design and schema registry. As a Distinguished Engineer, you will operate as a hands-on technical leader, influencing platform strategy, guiding architectural decisions, mentoring senior engineers, and partnering closely with application teams to design and operate complex, high-scale systems. You will help build sophisticated tooling and platforms on top of open-source and commercial database technologies, tailoring them to Walmart’s scale, reliability, security, and developer productivity needs. What You’ll Do Define and drive the long-term technical vision, architecture, and roadmap for the data services teams. Lead the design and evolution of highly available, scalable, secure, and operationally efficient NoSQL platforms that support mission-critical workloads at enterprise scale. Diagnose and resolve complex production issues across large installations, including performance degradation, query regressions, replication issues, availability incidents, capacity constraints, and operational bottlenecks. Build and influence sophisticated tooling, automation, and platform capabilities that improve database reliability, performance, observability, developer productivity, and operational simplicity. Partner with application engineering teams to design, review, and optimize database architectures for complex distributed systems and high-throughput workloads. Establish technical standards, best practices, reference architectures, and operational patterns for database usage across the organization. Influence senior engineering leaders, architects, product teams, and business stakeholders by clearly communicating technical strategy, trade-offs, risks, and execution plans. Mentor principal and senior engineers, raising the technical bar across database engineering, distributed systems, performance engineering, and production operations. What You’ll Bring 12+ years of software engineering, infrastructure engineering, or database engineering experience, with significant depth in database systems. Deep hands-on expertise in any database system at scale, preferably NoSQL databases with strong understanding of database internals. Proven experience debugging and operating complex database deployments in production, including high-availability, high-throughput, and low-latency environments. Experience designing and operating database platforms with strong reliability, availability, backup and restore, disaster recovery, observability, security, and compliance characteristics. Strong systems engineering background, with the ability to reason deeply about distributed systems, concurrency, networking, storage, failure modes, and capacity planning. Experience building automation, tooling, or platform capabilities around open-source or commercial database systems. Proven ability to define technical strategy, drive architecture across teams, and influenc
