Job description

Summary

QuEra Computing, Inc. seeks a creative and collaborative Scientific Software Engineer to help solve the unique software challenges of integrating high-level applications into state-of-the-art neutral-atom quantum computers. You will have the opportunity to work with a vibrant scientific software team and a community of industry and academic collaborators and to help our growing team of diverse experts address fascinating challenges, ranging from classical compiler techniques to direct integration with low-level hardware components. Using our open-source toolchain, Kirin, you will be building QuEra's compiler pipeline together with experimental & computational physicists from low-level hardware instructions to high-level programming languages. This involves the development of new features and infrastructure for hardware execution. You will be co-designing compilers and hardware infrastructure for the next generation of quantum computing using cutting-edge neutral-atom and quantum error correction technologies. This emerging direction involves novel challenges in both engineering and science.

Responsibilities

  • Develop and maintain domain-specific languages (DSLs) involved in the compilation pipeline
  • Support customers when usage questions and technical issues arise
  • Create comprehensive documentation for our SDK Bloqade and compiler infrastructure Kirin.
  • Collaborate with scientists and our hardware control team to plan and develop hardware features required for executing QEC algorithms
  • Collaborate with other members of the scientific software team to deliver new language and hardware features including new gates, atom shuttling instructions, and low-level pulse control features

Qualifications

  • Ph.D. in Computer Science or Physics with a focus on one or many of quantum computation, quantum architecture, quantum programming language & compilation or quantum physics, or equivalent professional experience
  • Enthusiastic about building tools and documentation used by non-software developers
  • Experience with Python semantics, Python type hints, and the CPython APIs
  • Knowledge of the full lifecycle of software development, including version control, code review, testing, CI/CD, logging, profiling, debugging, and documentation

Preferred Qualifications

  • Experience with Static Single Assignment intermediate representation-based compilers and compiler engineering using LLVM/MLIR
  • Experience in technical writing
  • Experience in programming language and compiler design
  • Deep understanding in topics including quantum physics, quantum algorithms, quantum error correction, and quantum compilation
  • Experience in creating education content for quantum computation topics
  • Experience in open-source collaboration and contribution with good record in GitHub contributions

QuEra Computing Inc does not presently have an established entity in Canada and therefore, this hire, which will include benefits eligibility, paid time off etc. will be handled through a third-party Employer of Record.

QuEra is committed to cultivating a diverse work environment and is proud to be an equal opportunity employer. We highly value diversity in our current and future employees and do not discriminate (including in our hiring and promotion practices) based on race, religion, color, national origin, gender, gender expression, sexual orientation, age, marital status, veteran status, disability status, or any other characteristic protected by law.
