Senior Software Engineer – Compiler

IonQ is developing the world's most powerful full-stack quantum computer based on trapped-ion technology. We are pushing past the limits of classical physics and current supercomputing technology to unlock a new era of computing. Quantum computing has the potential to impact every area of human society for the better. IonQ’s computers will soon redefine industries like medicine, materials science, finance, artificial intelligence, machine learning, cryptography, and more. IonQ is at the forefront of this technological revolution. 

We are looking for a software engineer to join our small but effective compiler engineering team. As a software engineering on the compiler team, you’ll be part of a customer-obsessed, cross-organizational and cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems. You will be critical to the company’s success, delivering results with measurable impact.

As part of the compiler engineering team, you will be responsible for developing and maintaining ahead-of-time (AOT) and just-in-time (JIT) compilation for quantum computing, including quantum machine learning and quantum chemistry.

Responsibilities:

• Design, develop, test, deploy, maintain and improve our quantum compiler stack; we’re a small team and we count on each other to run with projects independently.
• Perform R&D to support new hardware platforms, programming paradigms, and software tooling to enable optimal performance for quantum computing workloads.
• Deliver world-class quantum circuit optimizations with compiler innovations and efficient execution of those innovations; convert abstract descriptions of algorithms into efficient and understandable software implementations
• Help the industry define programming models, algorithms, and intermediate representations for quantum computing.
• Interpret and communicate complex concepts to the wider team.
• Collaborate with an experienced interdisciplinary staff.
• Participate in design and code reviews.
• Approach problems pragmatically.
• Help us continuously improve how we do things.

The ideal candidate will show potential for: leading and contributing to multiple simultaneous development efforts, projects, and initiatives; balancing technical expertise and savvy with strong business judgment to make great technology decisions; striving for simplicity and demonstrating creativity and incisive judgment.

You’d be a good fit with:

• Bachelor’s Degree in Computer Science, Math, or a related field; non-traditional backgrounds are welcome.
• 6+ years of development experience in compiler optimization for various architectures.
• Strong knowledge of Python and a systems programming language such as C++/Rust, or a highly-productive language like OCaml; and a strong math background, especially linear algebra.
• Experience with algorithm design and development, benchmarking, and performance-oriented optimizations.
• Strong focus on testing and software quality.

You’d be a great fit with: 

• An Advanced degree in Computer Science, Math, or a related field; non-traditional backgrounds are welcome.
• Experience developing projects using MLIR/LLVM and/or Qiskit, Cirq, or the like.
• Understanding of advanced compiler optimization techniques.
• Education or training in quantum computing and/or quantum information science (such as work experience, coursework, thesis, or peer-reviewed publications).
• Experience developing toolkits, compilers, or runtime environments for heterogeneous architectures.
