Principal, Software Engineer

GenAI-experienced Software Engineer

We are seeking a GenAI-experienced Software Engineer with deep expertise in full-stack application development, enterprise-scale architecture, Large Language Model (LLM)-generated code, and the use of LLMs in agentic solutions.

The primary mission of this role is to design and build automations that measure, report on, and suggest improvements to Operational Excellence (OE) and Engineering Excellence (EE) across Sam's Club's Merchandising and AI Labs (SCMAL) applications, logged incidents, and engineering teams.

Automations will monitor team and application compliance with OE/EE standards and with required Service Level Agreements (SLAs) for response times and implementation timelines. Solutions will leverage GenAI coding assistants and modern agentic AI architectures, including Retrieval-Augmented Generation (RAG) and Model Context Protocol (MCP). New AI technologies may also be evaluated for use across SCMAL.

This role requires both hands-on development and technical leadership.

What You'll Do

AI Application Development

Use GenAI to accelerate the design and implementation of end-to-end applications using backend technologies such as Python, Java, Node.js, and Go.

Incorporate communication components including email and SMS into application workflows.

Integrate LLMs, MCP, and agent-based workflows into enterprise applications that replace manual OE/EE tracking and project management.

Build modular, configurable, reusable frameworks that scale across hundreds of engineering teams.

System Architecture & Scalability

Architect and deploy systems using Kubernetes, containerized microservices, and service-oriented architectures.

Ensure high availability, observability, and reliability for AI-powered applications.

Optimize systems for performance, maintainability, and scalability within large enterprise environments.

Automation & Efficiency with GenAI

Automate OE/EE metrics, modernization tracking, and engineering maturity assessments using AI-driven workflows.

Build AI tools that reduce manual reporting and project management overhead.

Replace manual follow-ups and escalations with intelligent agentic workflows.

Develop AI agents that deliver personalized team notifications and insights.

Support scenarios such as AI-driven OKR tracking, automated engineering dashboards, AI-assisted follow-ups, and intelligent escalation handling.

Operational & Engineering Excellence

Apply OE/EE principles to ensure designs are scalable, maintainable, and aligned with productivity goals.

Standardize AI-assisted practices for CI/CD, code reviews, testing rigor, and observability.

Partner with leadership to embed automation-first practices into operational models.

Technical Leadership

Represent SCMAL in company-wide OE/EE forums.

Lead OE/EE champions to act on organizational priorities.

Communicate advancements, tooling updates, and best practices to the broader developer community.

What You'll Bring

Full-stack engineering experience with exposure to AI/ML and DevOps-focused development.

Strong backend development skills using Python, Java, or similar languages.

Hands-on expertise with Kubernetes, microservices, and service-oriented architectures.

Ability to design and scale enterprise software that automates operational workflows.

Experience with LLM APIs, MCP, and GenAI frameworks.

Strong programming discipline including CI/CD, automated testing, observability, and monitoring.

Familiarity with cloud-native stacks such as GCP and Azure.

Preferred Qualifications

Passion for OE/EE automation and reducing manual work.

Experience with multi-agent workflow orchestration.

Builder mindset with the ability to ship scalable GenAI applications quickly.

Strategic yet execution-focused, balancing innovation with enterprise readiness.

Continuous learner with a drive to expand GenAI adoption across the enterprise.

Strong frontend skills in React, Angular, TypeScript, or JavaScript.

Success Measures

Delivery of production-ready GenAI applications that automate OE/EE workflows.

Reduction in manual project management tasks and escalation cycles through AI automation.

Measurable improvement in developer velocity and satisfaction.

Increased adoption of AI-driven tooling across engineering teams.

Tangible gains in operational efficiency and engineering excellence.
