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. Our mission is to commercialise atom-based quantum products that provide orders of magnitude improvements in performance and computing applications.
Infleqtion has offices in the USA, United Kingdom and Australia. This is a full-time position in our Kidlington and Harwell offices. Our flexible working policy enables all full-time employees to work up to 2 days a week from home as work permits.
Infleqtion is seeking a Senior Research Software Engineer to architect and develop software across the full quantum control stack, enabling high-performance operation of both quantum computers and quantum sensors. This role spans low-level hardware integration, real-time control systems, waveform generation, calibration automation, experiment orchestration, and scalable data pipelines. You will work at the boundary between physics and production software, partnering with physicists and hardware engineers to translate experimental requirements into robust, deterministic, and extensible control infrastructure. The ideal candidate brings deep systems programming expertise, experience with hardware-adjacent or real-time systems, and a strong foundation in scientific or high-performance computing, with a passion for building the core software that drives next-generation quantum technologies.
Job Responsibilities
- Design, develop, and deploy reliable, maintainable, scalable, and fault-tolerant backend services and frameworks that control and calibrate our quantum hardware.
- Collaborate with interdisciplinary teams, including scientists, opto-mechanical engineers, and electrical engineers, to solve complex problems and deliver high-quality software solutions.
- Empower interdisciplinary teams to create the tools they need by teaching engineering and programming best practices.
- Mentor and guide junior engineers, fostering their growth and enhancing the team's technical expertise.
- Lead code and design reviews, upholding engineering best practices and promoting a culture of quality and collaboration.
- Support and debug all layers of the control stack from real-time embedded kernels to distributed and cloud-based services.
- Advocate for and implement innovative software development methodologies and tools to improve team efficiency and product quality.
Qualifications
- Bachelor's degree in Engineering, Applied Mathematics, Physics or related field and a minimum of 5 years prior work experience in a scientific domain.
- Experience with Python and at least one compiled language, with a desire to learn and work in Rust.
- Experience with Linux and virtualization technologies like Docker.
- Good verbal and written communication skills, able to effectively share information with technical and non-technical staff.
- Good collaboration skills, able to work in a team environment where engagement and participation are an expected part of successful job performance.
- Skilled in typical software engineering disciplines: testing, debugging, version control, error-handling, readability, documentation, general code health, etc.
- Desire to constantly improve and learn inside and outside of expertise.
Desirable Skills or Knowledge
- Domain-specific experience in statistics, machine learning, or AMO physics.
- Experience with Numpy, Scipy, and Pytorch.
- Experience with image analysis, emphasis on realtime object detection.
- Experience with databases (relational and non-relational) including but not limited to timeseries data, SQL, and ETL processes.
- Experience creating and maintaining CI/CD pipelines, and Python package creation with C or Rust extensions.
- Experience developing basic GUIs and/or web front-end applications.
