- 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
What the job involves
- We are seeking a Software Technical Lead to join the team building the control system software for Infleqtion’s quantum computers as both an individual contributor and manager for a handful of other engineers on the team
- The ideal candidate is an experienced backend engineer with a strong background in creating robust and scalable scientific applications who also has an interest in people management to help their team-mates achieve their potential
- You will play a crucial leadership role in designing, building, and maintaining backend services and control systems that drive our neutral atom quantum processors
- 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
- Mentor and guide software engineers as direct reports, 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
- 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
- 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
Our take
Quantum physics is a rapidly developing scientific field that promises great innovations within computing, with some working quantum computers already existing. However, such computers are extraordinarily expensive and complex to operate, making it difficult for startups to leverage the technology and apply it to commercial products.
Infleqtion, previously known as ColdQuanta, develops quantum computers, sensors, and networks, integrating them together to form an ecosystem of cloud-hosted quantum infrastructure readied for commercialization. This empowers businesses to leverage quantum computing without them needing their own quantum computer, accelerating adoption of the tech.
While quantum computing has rapidly developed from proof-of-concept to practical applications in the last decade, it has yet to break into common use. By increasing accessibility to the current state of practical quantum technology, Infleqtion should be able to help disrupt industries across the board. Its research arm, which has retained the "ColdQuanta" identity, remains primed to bring new advances to the space, which will, in turn, be more quickly commercialized. Substantial grants awarded in 2024 will help Infleqtion develop its quantum clock product for precision timing.
