We are seeking an Chief Platform Architect for locations in CO, MN, or UK.

As the Chief Platform Architect for the Quantum Software Developer Platform, you will act as the technical authority for designing Quantinuum’s developer platform—access portals for quantum computers, hybrid workflow orchestration, tooling access, documentation, and security. You will work with other leaders on hardware‑software co‑design efforts, ensuring the platform is scalable and supports our quantum processors. You will mentor senior engineers, uphold coding standards, and drive the technical roadmap to translate business needs into robust, production‑ready systems.

• Own the design and specifications of a high-performance developer platform.
• Refine quantum computer access API and web portal architecture for performance, scalability, and multi‑region operation.
• Transform the web portal into an application development and delivery framework by leveraging a cloud‑based hybrid workflow engine and reusable quantum/classical application components.
• Define standard interfaces for hosting application components and building applications by both internal and external developers.
• Ensure security and reliability as the platform scales.
• Deliver customizable cloud‑based hybrid applications to end users.
• Work across the business to define and maintain the technology roadmap, translating business goals into technical requirements and evaluating new technologies.
• Foster a culture of excellence by establishing best coding practices, conducting architectural reviews, and mentoring senior software engineers.

• Deep knowledge of cloud platforms (AWS, Azure, or GCP) and cloud-native solutions.
• Expertise in CI/CD pipeline design, developer portals (e.g., Backstage), and observability tools.
• Demonstrated success designing large-scale software systems.
• Proven ability to lead architectural work for large-scale projects and influence teams without direct authority.
• Excellent communication skills, able to explain complex technical concepts to both technical and non‑technical stakeholders.
• Bachelor’s degree in Computer Science, Engineering, or related field;
  Master’s or PhD preferred.
• Prior experience designing and architecting developer platforms.
• Experience building platform engineering teams from the ground up.
• Background in Site Reliability Engineering (SRE).
