Software Architect

About This Role

This is a hands-on architect role for an engineer who operates at the enterprise level, owning solution design, solution architecture, and software development end to end. The architect will lead the architecture of Nucor's manufacturing execution systems (MES) and their modernization alongside the ERP landscape, as well as the data and integration fabric that ties the mills to the enterprise. The role involves defining patterns, standards, and guardrails, making build-versus-buy and technology-selection calls, and partnering with mill-embedded engineers, product, and enterprise stakeholders.

Responsibilities

• Set the technical direction for how Nucor designs, builds, and ships manufacturing software
• Own solution design, solution architecture, and software development end to end
• Lead the architecture of Nucor's manufacturing execution systems (MES) and their modernization alongside the ERP landscape
• Lead the data and integration fabric that ties the mills to the enterprise
• Define the patterns, standards, and guardrails the team builds against
• Make build-versus-buy and technology-selection calls
• Partner closely with mill-embedded engineers, product, and enterprise stakeholders to turn operational complexity into reliable, high-quality systems
• Make AI-native development the way NBT builds, architecting AI into products (retrieval-augmented generation, agentic systems, and evaluation-driven delivery)
• Use AI and agentic tooling to accelerate the entire software lifecycle
• Bring leading engineering organization practices to the team
• Architect and build, multiplying the engineers around you
• Shape how Nucor manufactures steel for decades to come

Requirements

• Bachelor's degree in Computer Science, Software Engineering, or a related field; or equivalent professional experience
• 6+ years building and shipping production software, with demonstrated architecture or technical-leadership responsibility (a formal "architect" title is not required)
• Deep proficiency in at least one modern language (Python, C#, or TypeScript/JavaScript), with the breadth to review across several
• Proven solution and software architecture: distributed systems, integration and event-driven design, API design, data modeling, and sound technology-selection and build-vs-buy decisions
• Deep, hands-on AI and LLM capability, both architecting AI-native systems (retrieval-augmented generation, agent frameworks, evaluation-driven development, LLMOps) and using AI/agentic tooling to accelerate the full software development lifecycle
• Experience designing integration across system boundaries via APIs and events
• Cloud architecture experience (Azure preferred)
• Demonstrated track record of taking systems from architecture through delivery, setting engineering standards, and elevating teams, leading through influence, mentoring, and example
• Legally authorized to work in the US (Nucor Business Technology (NBT) will not sponsor the need for a visa now or in the future)
• Ability to initiate, lead, and uphold safety policies, practices, procedures, and housekeeping standards at all times

Nice to have:

• Enterprise integration experience across MES, ERP, and data platforms (via APIs and events)
• Prior ERP (SAP, Oracle E-Business Suite, or S/4HANA) and/or MES implementation experience
• Cloud architecture on Azure specifically; OCI also considered
• Manufacturing or industrial domain knowledge
• Experience leading large-scale legacy modernization or platform migration
• Track record establishing AI-native engineering practices or developer-productivity platforms (evaluation harnesses, LLMOps, agentic developer tooling)
• Strong fundamentals in testing strategy, system design, observability, and CI/CD at scale
• Cloud or architecture certifications; open-source contributions, patents, or public technical leadership

Benefits

• Medical, Dental, Vision, and Disability Insurance
• 401K and Roth accounts
• Profit sharing
• Pay-for-performance bonuses
• Paid parental leave
• Tuition reimbursement
• Stock program
• Scholarships

Important Details
