Application Engineer

Position Purpose

The Application Engineer is responsible for developing net-new solutions and refactoring prototype applications into secure, reliable tools that drive business profitability, increased efficiencies, and improved customer experience. While a major focus of this role is hardening AI-assisted prototypes for broader, ongoing use, you will also occasionally design and build new applications from the ground up to advance The Home Depot's analytics capabilities.

Based on the specific needs of the team, this role requires proficiency in application engineering specializations such as secure coding, API and Model Context Protocol (MCP) integrations, testing and quality assurance, and data pipeline integration.

As an Application Engineer, you will collaborate with data engineers, analysts, data scientists, and business partners to architect new tools and productionalize existing prototypes. You will manage integration points for AI agent interactions, proactively balance workload and priorities within the team, and consistently communicate progress. These responsibilities require effective communication skills, relationship-building across technical and business partners, and the engineering proficiency to deliver solutions the organization can completely rely on.
