Quantum Software Engineer

Description 

Infleqtion is on a mission to commercialize atom-based quantum technologies that deliver orders-of-magnitude improvements in sensing and computing applications. As a deep-tech startup, we embrace a results-driven, fast-paced, and customer-focused approach to innovation. We are seeking self-motivated, energetic individuals with exceptional problem-solving and technical skills to help drive our Quantum Sensing mission forward. We encourage applications from physicists with computational and/or theoretical backgrounds, particularly those with experience in Atomic, Molecular, and Optical (AMO) physics and coherent control of quantum systems such as ultra-cold atoms or multi-level systems. 

Role and responsibilities 

• Design, build, and test numerical simulations of physical systems, and work with experimental colleagues to incorporate real-world physical effects into the simulations 

• Use GPUs or other High Performance Computing techniques to speed-up simulations 

• Drive results and present findings to customers 

• Stay up-to-date on literature, assess and pursue cutting edge quantum simulations for novel applications 

• Communicate and interpret cutting-edge research in both theory and experiment with colleagues 

• Customer-centric focus on solving end-user needs and proposing new work to customers 

• Ownership of codebases to maintain high usability and performance. 

• Mentor and teach junior team members as indirect reports. Supervise interns.

WORKING CONDITIONS and PHYSICAL REQUIREMENTS 

Work will normally be performed in an office and laboratory environment and around technical equipment including computers and lasers.  We ask that candidates be able to efficiently use automated office equipment such as laptops, copiers, and printers; able to effectively engage in communications (via phone, computer, or in-person).  Any required Personal Protective Equipment will be provided and must be properly used in accordance with company requirements. 

• PhD in computational AMO physics or related field; or equivalent related professional experience (4+ years); If you have substantially more experience than this and are excited to apply, please do! We will also consider hiring at the Senior Quantum Physicist level. 

• Experience in writing simulations of quantum systems and light-matter interaction 

• Experience using common software language and tools for simulation such as Python, NumPy, SciPy, Matplotlib 

• Experience optimizing numerical simulations for high-speed performance 

• Demonstrated ability to understand end user needs and connect real-world challenges with quantum solutions 

• Demonstrated ability to work and communicate with all levels of an organization; Professional-level communication skills, including verbal, written, and presentation skills 

• Demonstrated ability to work comfortably in a highly collaborative, cross-functional, team-oriented, and matrixed environment 

• Desire and demonstrated ability to thrive and produce results in a fluid, dynamic, and fast-paced environment 

• Demonstrated ability to learn new and complex topics quickly 

• Resourceful problem-solver who collaboratively identifies effective paths forward with demonstrated expertise in executing productization efforts 

• Passion for solving complex problems and challenges in a highly technical and scientific environment 

• Ability to travel domestically and (potentially) internationally up to 10% 

It is a plus if you have: 

• Experience simulating physics of Bose Einstein condensates or other cold/ultra-cold atom systems 

• Experience simulating physics of multi-level systems such as Rydberg atoms 

• Familiarity with quantum sensing protocols and/or machine learning techniques used to optimize quantum sensors 

• Familiarity with neutral atom quantum computing and Rydberg-based entangling gates 

• Familiarity with quantum optimal and robust control techniques 

• Familiarity with quantum information theory 

• Experience running and optimizing numerical simulations on GPUs 

• Experience using simulation to study systematic effects in real-world experiments 

• Familiarity with Git, Linux, and command line interface (CLI) tools 

• Enthusiasm for staying up to date with latest developments in relevant physics fields and reviewing relevant papers for the team 

The targeted salary range for this role is $135,000 to $160,000 on an annualized basis plus eligibility to participate in our annual incentive plan.

In addition to your base compensation, we offer a generous Total Rewards program which includes:

• 100% company paid Employee coverage for Medical, Dental, Vision, and Short/Long Term Disability insurance programs
