All of these products and services are supported by scalable and powerful infrastructure, ensuring a secure and seamless employee and customer experience across stores, digital channels, and distribution centers.

WHAT YOU'LL DO...

The Change Engineering organization designs and builds intelligent capabilities that enable safe, reliable, and efficient technology change across the enterprise. Our mission is to enable faster delivery of business value while reducing operational risk to critical systems. We achieve this through automation, AI-driven risk intelligence, and deep integration with cloud, observability, topology, and ITSM platforms. We are looking for a hands-on Staff Software Engineer to provide technical leadership in designing, building, and scaling intelligent systems that power our enterprise Change Engineering solution. This is a highly technical role requiring strong expertise in software engineering, distributed systems, cloud platforms, AI/ML, and enterprise integrations, with a focus on building production-grade solutions at scale.

The ideal candidate will operate at the intersection of AI/ML, platform engineering, and IT operations, translating complex operational challenges into scalable software and intelligent automation. You will design and build intelligent workflows, decision-support systems, and automation that improve the safety, reliability, and efficiency of technology
changes across the enterprise.

As a Staff Engineer, you will be expected to set technical direction, influence cross functional teams, perform design reviews, mentor engineers, and hands-on delivery. You will help evolve Change Engineering from individual automation and workflows into a scalable, intelligent platform.
