SUNNYVALE, CA, United States; BENTONVILLE, ARSalary: $169000 - $338000/year

Type:
Full time / Regular/Permanent Company:
Walmart Business Segment:
Home Office Own the Performance Architecture:
Define the long-term architectural vision for an enterprise continuous profiling platform capable of safely executing across multi-tenant Kubernetes environments at massive scale.

Drive Runtime

Innovation: Lead the technical evaluation, implementation, and deployment of advanced introspection technologies, balancing in-process runtime diagnostics (e.g., Async Profiler, JFR tracking) against system-wide, kernel-levelinstrumentation (e.g., eBPF-powered frameworks like Zymtrace).Architect for Strict Compliance:
Establish the end-to-end security wrapper, access controls, and data-sanitization pipelines for profiling artifacts, ensuring zero leakage of sensitive data (PAN/SAD) within highly regulated Cardholder Data Environments (CDE) to satisfy PCI-DSS requirements.

Optimize Infrastructure Efficiency:
Collaborate with Platform Engineering to leverage profiling insights into automated scheduling enhancements, resource utilization metrics, and intelligent bin-packing, directly converting telemetry into measurable cloud capacity savings.

Influence and Standardize:
Act as the primary authority on runtime internals across Global Tech, guiding critical architectural trade-offs, driving the adoption of standardized profiling patterns, and mentoring engineering teams on advanced diagnostics.

What You’ll Bring Deep Runtime Internals Expertise:
Comprehensive, low-level mastery of the Hot Spot JVM (Java 17 and above), including garbage collection mechanics, JIT compiler dynamics (C1/C2), execution loop thread dynamics, and native memory management.

Advanced Introspection Capabilities:
Proven hands-on experience building or scaling continuous profiling solutions utilizing Async Get Call Trace , Java Flight Recorder (JFR), or deploying Linux  and hardware performance counters.

Kernel-Level & eBPF Systems Engineering:
Deep understanding of Linux operating system kernels, process schedulers, and memory maps, with practical exposure to writing, verifier-validating, and deploying eBPF bytecode via node-level Daemon Sets.

High-Compliance Architecture Design:
Demonstrable experience navigating security contexts, container sandboxing, and access controls (RBAC/mTLS) within scoped compliance boundaries, with a solid grasp of balancing infrastructure privileges against engineering visibility needs.

Strategic Technical Leadership: A proven track record of guiding cross-functional engineering directions, defining architecture for mission-critical platform tools, and executing large-scale technology rollouts across a global footprint.
