Job Details

Infleqtion is on a mission to commercialize atom-based quantum technologies that deliver orders‑of‑magnitude improvements in sensing and computing applications. We are seeking self‑motivated, energetic individuals with exceptional problem‑solving and technical skills to help drive our Quantum Computing mission forward.

At Infleqtion we embrace a startup mentality driven by results, urgency, and customer‑focused innovation:

• We break down barriers between disciplines, stepping in wherever we can make the biggest impact.
• We thrive in uncertainty, embracing challenges as opportunities.
• We move quickly to prototype while never losing sight of the critical importance of systems engineering process and attention to detail.
• We take bold, calculated risks to drive progress.

The ideal candidate is an experienced backend engineer with a strong background in creating robust and scalable scientific applications. The role involves designing, building, and maintaining backend services and control systems that drive our neutral atom quantum machines.

• Design, develop, and deploy reliable, maintainable, scalable, and fault‑tolerant backend services and frameworks that control and calibrate our neutral atom quantum computers.
• 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 services.
• Advocate for and implement innovative software development methodologies and tools to improve team efficiency and product quality.

• Bachelor's degree in Computer Science, Applied Mathematics, Physics, or related field and a minimum of 5 years prior work experience.
• Experience with Python and at least one compiled language, with a desire to learn and work in Rust.
• Experience with Linux and virtualization technologies such as 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 expected parts of successful performance.
• Skilled in typical software engineering disciplines: testing, debugging, revision control, error handling, readability, documentation, general code health, etc.
• Desire to constantly improve and learn both inside and outside of expertise.

• Domain‑specific experience in statistics, machine learning, or AMO physics.
• Experience with Numpy, Scipy, and PyTorch.
• Experience with image analysis, emphasis on real‑time object detection.
• Experience with databases (relational and non‑relational) including time series data, SQL, and ETL processes.
• Experience creating CI/CD pipelines and Python package creation with C or Rust extensions.
