Position Summary...What you'll do...About the Team: The Marketplace Platform Software Engineering team builds shared frontend frameworks, orchestration (micro frontends/app shell), and build tooling that power Walmart Marketplace experiences for Sellers and Solution Partners. We partner closely with Product and UX/UI to deliver scalable, reliable platform capabilities, with a strong focus on performance, monitoring, and developer experience-including leveraging AI/ML and GenAI tools for smarter scaffolding, code generation, diagnostics, and workflow automation.
**Immigration sponsorship is not available for this role** What You'll Do: - Platform & frameworks: Build and enhance reusable web frameworks, shared build pipelines, and platform capabilities that support multiple product teams. Contribute to build optimization efforts including bundling, caching, tree-shaking, and code-splitting, while improving developer experience.
- Hands-on engineering: Spend most of your time writing code - implementing features, reviewing code, debugging issues, and improving application reliability and performance. Help maintain quality and consistency across the codebase.
- GenAI & agentic workflows: Use GenAI tooling to improve developer and platform workflows through smarter scaffolding, code generation, diagnostics, and automation. Explore and apply AI-assisted tooling to increase engineering productivity and reliability.
- Orchestration Layer (OL): Contribute to the design, implementation, and evolution of the Orchestration Layer (OL) that coordinates micro frontends, app shell, and shared services. Help ensure consistent lifecycle, routing, and integration patterns so applications run reliably at scale.
- Frontend craft: Build responsive UIs with TypeScript/JavaScript, HTML, and CSS. Work with React, Webpack (or similar), and modern frontend tooling. Apply established design systems and styling approaches for consistency, accessibility, and performance.
- Data layer & APIs: Work with GraphQL for platform and product data, including schema usage, queries/mutations, and client integration using tools such as Apollo Client or Relay. Help ensure efficient and consistent data access patterns across applications.
- Performance & health: Contribute to frontend performance improvements across load time, runtime behavior, and resource usage. Help optimize browser storage and memory usage, and support monitoring and performance best practices.
- Architecture & standards: Contribute to frontend and build architecture decisions. Stay current with modern frameworks and tooling. Help document patterns, conventions, and platform capabilities to support broader team adoption.
- Collaboration: Partner closely with engineers, product managers, and platform teams to deliver shared capabilities. Support technical initiatives, participate in design discussions, and help roll out new platform improvements.
What You Will Bring: - Frontend: Strong experience with TypeScript/JavaScript, HTML, CSS, and React. Solid experience with modern build tooling such as Webpack, Vite, or similar, along with frontend performance optimization practices.
- Orchestration Layer (OL): Experience contributing to Orchestration Layer patterns such as app shell, micro frontend coordination, shared lifecycle management, routing, or similar frontend platform orchestration approaches.
- GraphQL: Experience with GraphQL including queries, mutations, subscriptions, and client integration using tools such as Apollo Client or Relay. Familiarity with schema design is a plus.
- Platform / build: Experience working with build optimization, shared tooling, and monorepos. Familiarity with orchestration tooling such as Nx, Lerna, or similar is a plus.
- Performance: Demonstrated ability to improve load times, runtime performance, and resource usage. Understanding of browser storage, memory, and caching strategies.
- GenAI / tooling: Interest or experience using GenAI tools to improve developer workflows, automation, or agentic experiences. Openness to evaluating and adopting AI-assisted tooling.
- Code quality: Track record of writing clean, testable, maintainable TypeScript/JavaScript code and participating in thoughtful code reviews. Strong analytical and problem-solving skills.
- Collaboration: Experience contributing to technical initiatives, working closely with cross-functional partners, and communicating clearly in verbal and written form.
