The Role:
We are looking for a Senior Quantum Field Engineer to join our Field Engineering team at IonQ in Singapore. In this role, you will sit at the intersection of customers, markets, products, algorithms, applications and strategy, helping clients understand how IonQ’s quantum technologies can be applied to real business and technical challenges.
You’ll play an important part in helping IonQ build the world’s best quantum solutions by turning early customer interest into meaningful technical exploration, proofs of concept and ultimately production workflows. This is a highly technical, customer facing role where credibility, clarity and technical correctness come first.
Responsibilities:
In this position, you will work closely with customers, sales, product, applications, marketing, developer relations and engineering teams to explain IonQ’s portfolio, uncover client needs, shape technical solutions and support the growth of IonQ’s quantum computing business across Singapore and the wider APAC market.
You’ll have the opportunity to inspire prospective customers, lead technical discovery, translate business needs into technical workstreams and help bring quantum algorithms and applications to life across areas such as financial services, bioscience, chemistry, materials, optimisation, generative AI and other emerging domains.
• Lead customer facing technical discussions, demos and discovery sessions, explaining IonQ’s strategy, portfolio and quantum applications across compute, networking, security, sensing and space. • Translate client business needs into technical projects, working with IonQ’s Applications team to map quantum algorithms into application code and execute proofs of concept. • Work hands on in Python and quantum SDKs to prototype, adapt and explain existing quantum algorithms for specific customer use cases. • Guide customer conversations from early ideation through focused technical exploration, proof of concept development and potential production workflows. • Share market and customer insights with Product Management, Engineering, Marketing, Developer Relations and Business Development teams, while supporting conferences, events and awareness building activities.
Requirements:
To be successful in this role, you’ll bring strong technical foundations, excellent customer facing communication skills and a genuine interest in helping organisations understand where quantum computing can create value. We’re looking for someone who can adapt their communication to different levels of technical depth, build trust with customers, handle competitive objections and work effectively across both commercial and technical teams.
You’ll bring 5+ years of experience in a technical customer facing role such as field engineering, solutions architecture, technical sales, customer engineering or applied science, and a Bachelor’s degree or above in Computer Science, Machine Learning, Data Science, Chemistry, Physics, Engineering or another relevant STEM field. Hands on experience with Python and with Qiskit, Cirq or another quantum computing SDK is required, together with practical experience of existing quantum algorithms and how they map to real customer problems.
Preferred Qualifications:
• A Master’s or PhD in a relevant STEM field. • Experience delivering proofs of concept with customers, from early exploration through to working code. • Customer side industry experience in areas such as financial services, bioscience, chemistry, materials or optimisation. • Executive presence and experience representing a business at client meetings, events and conferences. • Broader software architecture skills alongside your quantum computing work.

Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone.
