Director, IT Enterprise Architecture

We are seeking a Director, IT Enterprise Architecture, in our Broomfield, CO, location. Quantinuum believes that employees work better, more efficiently, and more collaboratively in close proximity to other employees, where ideas can be exchanged readily, and decisions can be made more quickly for the benefit of the Company and our customers. All employees should work at their assigned location; however, this role may offer the opportunity to work remotely up to 2 days per week, with approval.

About the role:

The Director of Enterprise Architecture will lead, own, and elevate Quantinuum's IT architecture standards and architectural governance, driving the overall IT architecture, integration standards, technology roadmaps, and decision frameworks across the enterprise.

This role is accountable for materially improving the maturity of the IT organization—including architectural discipline, technology lifecycle management, and operating processes—so IT can scale reliably and efficiently as Quantinuum grows. You will help evolve IT from a reactive, project-centric model to a scalable, service- and platform-oriented approach that improves reliability, reduces complexity, and accelerates delivery.

This leader will be highly visible and influential, partnering with senior cross-functional leaders to guide enterprise-wide architectural decisions across business functions and IT. You will ensure the company selects, builds, implements, and supports secure, high-quality systems that are tightly integrated and aligned to current and future business needs.

A critical focus of this role is establishing architectural direction for AI/ML enablement, advanced data platforms, and hybrid compute (including GPU-accelerated workloads)—balancing cost, performance, scalability, and security—while aligning closely with R&D and business priorities.

• Enterprise Architecture Strategy, Roadmaps & Business Alignment
• Establish and own IT architecture strategy and multi-year roadmaps aligned to Quantinuum's technology and business strategies.
• Act as a trusted advisor and strategic partner to business leaders, translating business objectives into actionable architecture, roadmaps, and investment recommendations.
• Facilitate executive-level tradeoff discussions (cost, risk, speed, scalability) and drive decisions that align technology investments to measurable business outcomes.
• Build business cases and drive them forward for approval, communicating value in business terms.
• IT Maturity Improvement, Technology Footprint & Operating Processes
• Assess current-state architecture and operating patterns; define and execute a pragmatic plan to raise IT maturity, improve consistency, and reduce preventable operational load.
• Drive rationalization of the IT technology footprint (platforms, tools, integrations), reducing complexity and technical debt while improving stability and user experience.
• Partner with IT leaders to improve core operating processes such as intake/prioritization, architectural standards, change governance, service management alignment, and lifecycle management.
• Establish and maintain reference architectures and reference processes that enable repeatable delivery and scalable operations.
• Define and maintain enterprise architectural direction for AI/ML, data platforms, and advanced compute, including GPU-accelerated workloads and hybrid compute models.
• Partner with R&D, infrastructure, and application teams to align enterprise IT architecture with data-intensive and compute-intensive needs, ensuring secure and performance delivery.
• Develop reference architectures for AI enablement (e.g., data pipelines, model lifecycle considerations, governance, security controls, and platform integration patterns).
• Evaluate cloud vs. on-prem vs. hybrid architectures for AI and compute, balancing performance, cost, scalability, resilience, and compliance needs.
• Architecture Governance & Decision Quality
• Develop, communicate, and operate enterprise architecture governance that is lightweight, transparent, and enables delivery—while measurably improving decision quality, reducing rework, and managing architectural risk.
