STAFF, SOFTWARE ENGINEER

People Data Platform – Powering Secure, Enterprise-Scale People Insights at Walmart .The People Data Platform team at Walmart owns the centralized People Data Lake that enables trusted, cross-domain people insights across the enterprise. We build and operate a scalable data platform on GCP, ingesting data from multiple source systems and transforming it through a robust medallion architecture to deliver high-quality, analytics-ready data.

Our team designs data and semantic models that empower HR, business, and analytics teams to make data-driven decisions at scale. In parallel, we lead the Data Security charter for the People Data Lake, implementing encryption, masking, and fine-grained access controls to protect sensitive data while ensuring compliant and governed access.

The Workforce Intelligence Platform (WIP) builds the access and experience layer on top of this foundation-enabling secure, personalized, and scalable analytics consumption. WIP combines query execution, dynamic access control (RLS, CLS, ABAC), and API-driven architecture to power dashboards, applications, and AI-driven data interactions.

Operating at the intersection of big data, cloud, security, and platform engineering, we are building a future-ready analytics platform that supports one of the world’s largest workforces.

We are looking for a Staff Full Stack Engineer to lead the design and development of WIP as a scalable, secure, and extensible analytics platform. This role will drive end-to-end architecture across frontend, backend, and data access layers, with a strong focus on performance, security, and platform capabilities.

You will work on solving complex problems such as dynamic data access, real-time security enforcement, high-scale query execution, and AI-driven analytics experiences, while mentoring engineers and influencing platform direction.

What you will do

• Own end-to-end product and platform experience, spanning frontend (React) to backend services and data access layers
• Design and build intuitive, high-performance UI/UX for dashboards, filters, and data interaction experiences
• Develop responsive, scalable frontend applications using React, TypeScript, and modern UI frameworks (AG Grid, charting libraries, component systems)
• Partner with product and design to translate complex data workflows into simple, user-friendly experiences
• Build and optimize backend services (Java/Spring Boot or Python/FastAPI) for query execution, caching, and analytics delivery
• Lead development of dynamic access control systems (RLS, CLS, ABAC) enforced at query time
• Build variable-driven query frameworks enabling reusable and flexible analytics experiences
• Optimize performance across the stack, including frontend rendering, API latency, caching, and BigQuery interactions
• Drive API-first design and platform extensibility, enabling integration with internal tools and workflows
• Contribute to AI-enabled user experiences (NLQ interfaces, semantic discovery, AI-assisted workflows)
• Ensure high reliability, observability, and scalability across distributed systems
• Mentor engineers and elevate engineering and UX standards across the team

What you will bring

• 7-9 + years of experience building scalable full-stack applications and platforms
• Strong expertise in frontend development (React, TypeScript, modern state management, component-driven architecture)
• Experience building data-heavy UI applications (dashboards, tables, filters, interactive visualizations)
• Proficiency with UI libraries and tools such as AG Grid, Recharts/D3, or similar visualization frameworks
• Strong understanding of UI/UX principles, with ability to design intuitive and performant user experiences
• Solid backend experience with Java (Spring Boot) or Python (FastAPI) and API design (REST/GraphQL)
• Experience with distributed systems, microservices, and high-scale platforms
• Familiarity with data systems (BigQuery, SQL optimization, large datasets)
• Hands-on experience with performance optimization across frontend and backend (rendering, caching, concurrency)
• Strong understanding of security concepts (RBAC, RLS, CLS; ABAC is a plus)
• Experience with cloud platforms (GCP preferred) and modern DevOps practices
• Proven ability to design scalable systems and influence architecture decisions
• Strong collaboration skills to bridge engineering, product, and design
