About the position
Infleqtion is a global quantum technology company solving the world’s most challenging problems. The company harnesses quantum mechanics to build and integrate quantum computers, sensors, and networks. From fundamental physics to leading-edge commercial products, Infleqtion enables 'quantum everywhere' through our ecosystem of devices and platforms. We are seeking an Applications Engineer to lead customer application development focused on prototyping Infleqtion’s cutting-edge Quantum RF sensor technology. This hands-on role is critical in bridging R&D and customer engagement. The ideal candidate is someone who thrives in fast-paced, cross-disciplinary environments and is excited by the opportunity to develop compelling technology demonstrations that directly align with market needs. This individual will work in the QRF group within our Emerging Technologies business unit and collaborate with Business Development (BD) teams to identify customer interests, develop end-to-end system performance analyses, and translate requirements into functional Rydberg RF system prototypes for customer application demos. Success in this role requires strong technical breadth across both quantum sensors and classical RF systems, creative problem-solving, and excellent communication skills.
Responsibilities
- Organize, manage, and maintain Infleqtion’s Quantum RF demonstration system infrastructure
- Collaborate with BD teams to interpret customer needs and shape product application narratives
- Establish and analyze use case link budgets to inform prototype specifications and operational requirements
- Collaborate with QRF team members to design, build, and deploy proof-of-concept systems that showcase the utility of Rydberg RF sensors in real-world scenarios
- Collaborate with software development teams to design and test custom software interfaces for new or existing hardware platforms, resulting in cohesive customer-facing demonstrations
- Develop simulations that demonstrate feasibility of application concepts and contribute to technical publications and white papers
- Document prototypes and demonstrations, write test protocols, and assist in transferring successful applications to future products
- Support public and private demonstrations and assist in customer workshops
