Role:

IonQ is seeking a Staff Quantum Success Engineer to lead technical customer success in South Korea, as part of a cross functional team dedicated to delivering exceptional customer experiences. You will be IonQ's primary customer facing technical expert in the region, working hands on with Korean research institutions, enterprises and government partners to drive real adoption of our trapped ion quantum computers.

As a trusted technical advisor, you will bridge deep platform and quantum algorithm expertise with customer empathy, guiding organisations through onboarding, performance optimisation, circuit design and workflow integration. It is a high visibility role that influences business and highly technical stakeholders, inside IonQ and out, and suits someone who is committed to continuous learning in quantum computing and loves sharing what they know.

Responsibilities:

You will drive adoption across major Korean accounts, translating contract terms into technical provisioning, leading onboarding and managing day to day technical engagement. You will build success plans and playbooks tailored to each account, remove barriers to adoption, standardise troubleshooting for job failures and provide direct, high touch technical support, coordinating with global teams across time zones to improve satisfaction and retention.

You will be the internal voice of the Korean customer across Product, Cloud Platform, Data Engineering, Operations, Product Marketing, Sales and Engineering, sharing insight on functionality, documentation and educational material, and helping refine term sheet language so customer expectations match technical capabilities. You will also help define new service offerings from customer feedback and keep several interconnected technical initiatives aligned with IonQ's strategic goals and schedules.

Key responsibilities include:

• Lead technical onboarding for major Korean accounts and manage day to day technical engagement.
• Guide customers on best practice for designing quantum circuits, applications and workflows in optimisation, machine learning and chemistry or materials simulation, working closely with IonQ's compiler and systems experts.
• Create workshops, challenges and curricula, including code, circuits, slides and videos, and deliver training in Korean and English.
• Design and maintain dashboards of job metrics, system usage and customer health, turning usage data into actionable technical intelligence.
• Represent IonQ on standards bodies, government committees and quantum working groups, and present at conferences and workshops in Korea and across Asia Pacific.

Requirements:

You will hold a Master's or PhD in Physics, Computer Science, Machine Learning, Operations Research or a related STEM field, with 5+ years in technical customer facing roles or equivalent and a proven record of performance. You will have 3+ years creating customer facing technical content such as training material, success plans, playbooks and workflows, hands on experience with Python and quantum frameworks such as Qiskit, Cirq, PennyLane or CUDA-Q, and working knowledge of Jupyter Notebook, Google Colab or similar platforms.

You will have a strong grasp of the physics and mathematics behind quantum computing, including linear algebra and probability, and exceptional technical and executive presentation skills, able to influence researchers, end users and C-suite executives alike. You will be a proven teacher of complex topics, from large lectures to one to one mentoring, and work well in a team. Fluency in Korean and professional proficiency in English are required. You will be based in South Korea, with up to 30% travel to customer sites and conferences, mainly within Korea and Asia Pacific, and occasional evening meetings to support global customers.

You’d be a great fit with:

• In depth knowledge of the strengths and weaknesses of different quantum hardware platforms, and of hardware and software dependencies.
• Demonstrated experience in quantum information science, applications and algorithms.
• Experience with SaaS platforms, REST APIs or HPC systems, and proficiency in SQL, data science or data analytics.
• Familiarity with subscription and renewal business models, and experience setting business strategy and objectives backed by data driven reporting.
• The ability to hold technical and business discussions across finance, pharmaceuticals and healthcare, chemistry, computer vision and operations research.
