About Team
GDF (Global Data Foundation) is part of Walmart's AI & Data organization - the team building the foundational data platforms that power AI, analytics, and decision-making across every Walmart banner and geography, from supply chain and merchandising to customer experience and enterprise AI agents.
Our newly created platform team is chartered with building next-generation data infrastructure at Walmart scale: reliable, high-throughput data pipelines, distributed processing systems, and platform capabilities that downstream teams across Walmart depend on every day.
What You'll Do
• Design, build, and operate distributed platform services and APIs using Java and Python, applied
against Kubernetes or equivalent cloud-native infrastructure.
• Apply domain-oriented design, system design, and low-level design (LLD) rigor to ambiguous platform
problems - evaluating dependencies, trade-offs, failure modes, scalability, cost, and long-term
durability before writing a line of code.
• Flex into data engineering work when needed: contribute directly to Spark-based data pipelines and
processing jobs, working comfortably in GDF's data engineering codebase alongside platform work.
• Build AI, GenAI, and agentic-powered platform capabilities: intelligent developer tooling, workflow
automation, agentic services, and AI-assisted operational tooling (monitoring, incident triage, capacity
planning).
• Own platform reliability, scalability, and observability - service-level objectives, distributed tracing,
alerting, and incident response for services you build, with a strong Operational Excellence /
Engineering Excellence discipline.
• Guide architecture and system design decisions across microservices, event-driven systems, and
enterprise integrations, with an explicit eye toward how platform choices affect downstream data
engineering workloads.
• Partner with data engineers, data scientists, and ML engineers to ensure platform services expose the
right primitives for data pipelines, feature stores, and model-serving paths.
• Establish engineering standards through architecture reviews, design reviews, code reviews, and
production readiness reviews for a team building process from scratch.
• As a Staff engineer, set technical direction and best practices within your team and technical domain
without needing a management title - mentor other engineers and influence GDF's broader platform
engineering standards.
• Continuously evaluate emerging platform, cloud, and AI/agentic technologies, adopting them
pragmatically where they improve reliability, productivity, or business value.
What You'll Bring
• Genuinely hands-on coding: 8+ years of professional software engineering experience building and
operating large-scale distributed platforms; strong proficiency in Java and Python is required -
comfortable writing, reviewing, and debugging production code, not just directing others. Additional
experience with Go, C++, or Scala is a plus.
• Operational Excellence (OE) and Engineering Excellence (EE) mindset is a required skill, not a
nice-to-have: SLO/SLA ownership, incident management and blameless post-incident reviews,
proactive reliability and quality metrics, and continuous improvement built into how you ship, not
bolted on afterward.
• Bachelor's or Master's degree in Computer Science, Engineering, or a related technical field, or
equivalent practical experience.
• Deep experience with microservices architectures, distributed systems, event-driven patterns, API
design, service contracts, and enterprise system integration - backed by strong system design,
domain-oriented design (DDD), and low-level design (LLD) skills, with demonstrated ownership of
production code and the judgment to evaluate trade-offs, failure modes, scalability, and cost.
• Deep understanding of cloud-native engineering practices - CI/CD, containerization, Kubernetes or
equivalent orchestration, infrastructure automation, and production operations.
• Strong exposure to Big Data / data engineering technologies - Spark required at a working level, with
familiarity in Hadoop/HDFS, Hive, or Kafka - enough to flex into data engineering work confidently, not
just integrate with it from a distance.
• Full exposure to AI and Agentic technologies: hands-on experience integrating model APIs and
GenAI/LLM tooling, building or operating agentic workflows (tool-calling agents, multi-step
autonomous systems), working with embeddings/vector search, and applying MLOps practices
(feature stores, model lifecycle, retraining pipelines) - not just conceptual awareness.
• Strong knowledge of reliability engineering - observability, distributed tracing, logging, metrics,
alerting, incident response, capacity planning, and fault tolerance for large-scale systems.
• Strong grounding in security, privacy, and enterprise engineering practices, including authentication,
authorization, data protection, and secure API design.
• Proven ability to translate ambiguous technical/business problems into clear execution plans,
particularly within a newly formed team without fully established process.
• Strong ownership mindset and technical judgment; comfortable operating with high autonomy in a
0-to-1 environment.
