Intern - Quantum Computing Scientist (Singapore)

We are seeking accomplished and motivated interns to join Horizon Quantum in building groundbreaking tools that will shape the future of quantum computing. As an intern, you will collaborate with our Science and Engineering teams to develop and deploy software tools that advance this rapidly developing field. You will have the opportunity to uncover novel applications of a full-stack compiler for quantum processors and contribute to the development of Horizon’s products along the way.
Quantum computing requires a uniquely collaborative approach, so you’ll work closely with team members and have a dedicated supervisor to guide your project, which is closely aligned with our core products. This role offers a unique opportunity to explore a career in quantum computing while gaining hands-on experience with our team. The internship will run from May-July 2026, with exact dates to be determined.

Your Mission
To explore innovative applications that leverage Triple Alpha, our Integrated Development Environment (IDE) and compiler, to unify quantum and classical computing.

Responsibilities

• Learn quickly and get up to speed to contribute to Horizon Quantum’s science, engineering and product development.
• Communicate regularly with your supervisor to give updates and integrate feedback into your work.
• Work with other scientists and engineers to implement, integrate and test use cases on our products.
• Maintain Horizon Quantum’s professional software development practices.

Requirements

• Be enrolled in an undergrad/graduate program in Physics, Computer Science, or other related technical field.
• Have completed coursework in quantum information or other areas of research related to quantum computing.
• Research experience in an area of study related to quantum computing is desirable.
• Programming experience with a scientific programming language or tool (for e.g. Python, C++, Matlab).
• Ability to work well in a team.
• Ability to work well autonomously.
• Passion for learning and a drive to succeed.

About Horizon Quantum
At Horizon Quantum, we believe quantum computing has the potential to spark a second revolution in computing. Our mission is clear — to enable a world powered by quantum computation. We are developing tools to simplify and expedite the process of developing software for quantum computers. We are an international team headquartered in Singapore, with an office in Ireland and key markets spread out worldwide. 
With Triple Alpha, we are developing a toolchain for taking a program written in a conventional language such as C or Python and transforming it into an accelerated quantum application. This requires automated algorithm synthesis to produce a high-level description of a quantum program for the task, paired with an optimising compiler to turn this into a processor-specific executable representation.

Note: This will be a paid internship
