Software Architect

Nucor Business Technology (NBT) is building the next generation of manufacturing software for Nucors steel operations and were looking for aSoftware Architectto set the technical direction for how we design build and ship it. This is a hands-on architect role for an engineer who operates at the enterprise level: someone who ownssolution design solution architecture and software developmentend to end and raises all three to the bar the best technology companies are setting right now.

Youll lead the architecture of Nucorsmanufacturing execution systems (MES)and their modernization alongside ourERPlandscape and the data and integration fabric that ties the mills to the enterprise. Youll define the patterns standards and guardrails the team builds against make the build-versus-buy and technology-selection calls and partner closely with mill-embedded engineers product and enterprise stakeholders to turn real operational complexity into reliable high-quality systems.

Just as important: youll makeAI-native development the way NBT expect our architects to architect AIintoour products retrieval-augmented generation agentic systems and evaluation-driven delivery and to use AI and agentic tooling to accelerate the entire software lifecycle. Youll bring the practices leading engineering organizations use today and make them how we work.

This is not a maintenance role and it is not an ivory-tower role. You will architectandbuild and you will multiply the engineers around you. Youll be shaping how Nucor manufactures steel for decades to come. This is a full-time permanent position based at the NBT office in Dallas TX.

Candidates must be legally authorized to work in the US (Nucor Business Technology (NBT) will not sponsor the need for a visa now or in the future).

Safety is the most important part of all jobs within Nucor; therefore candidates must be able to demonstrate the ability to initiate lead and uphold safety policies practices procedures and housekeeping standards at all times.
