Job description

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.

We are seeking a Senior Software Engineer to join the team building the control system software for Infleqtion's quantum computers. The ideal candidate is an experienced backend engineer with a strong background in creating robust and scalable scientific applications. You will play a crucial role in designing, building, and maintaining backend services and control systems that drive our neutral atom quantum machines.

JOB RESPONSIBILITIES

The duties and responsibilities outlined below include essential functions of the role. Depending on business needs, this role may perform a combination of some or all of the following duties. Duties, responsibilities, and activities may change, or new ones may be assigned at any time.

  • 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.

Requirements

  • 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 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, revision control, error-handling, readability, documentation, general code health, etc.
  • Desire to constantly improve and learn inside and outside of expertise
PREFERRED EXPERIENCE:
  • 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 CI/CD pipelines, and Python package creation with C or Rust extensions
