Principal Software Engineer, Compiler

Just like with classical computers, quantum computers need compilers to take high-level quantum programs and transform them to a series of optimal instructions—only in our case, in the end they come out as laser pulses. We’re looking for a Principal Compiler Engineer to build a collaborative team to architect and deliver our next-generation full-stack compiler for our quantum computers.

The ideal candidate will have experience leading or contributing to multiple simultaneous product development efforts, projects, and initiatives. You’ll have excellent interpersonal skills, and be able to balance technical expertise and savvy with strong business judgment to make great technology choices. You’ll strive for simplicity and demonstrate significant creativity and incisive judgment.

Day-to-day tasks for this role may include design and implementation of compiler features and optimizations, developing code generation techniques for novel hardware platforms, and mentoring and directing staff and working with hardware teams on future design considerations. In your first three months, you’ll be defining the architecture for our future compiler platform.

Responsibilities:

• Design, develop, test, deploy, maintain and improve our quantum compiler stack
• Ensure the quality of our compiler architecture through code and design reviews
• Deliver world-class quantum circuit optimizations
• Help hire compiler team members
• Assist in the career development of others, providing mentorship on advanced technical issues
• Help the industry define the next intermediate representation standards for quantum computing
• Collaborate with experienced interdisciplinary teams
• Help us continuously improve how we do things

You’d be a good fit with:

• Master’s degree in Computer Science or equivalent practical experience
• 10+ years experience developing optimizing compilers and scalable compiler architecture
• 5+ years of experience with C/C++ or equivalent systems language
• 3+ years experience in management and/or leading teams
• Proven experience in compiler middle-ends
• A passion for durable intermediate representations
• Excellent verbal and written communication skills
• A love of collaborating in an interdisciplinary environment

You’d be a great fit with:

• PhD in Computer Science, Physics, Mathematics, or Quantum Computing
• Code generation for non-CPU architectures (e.g. GPU, NPU)
• Prior research experience in reversible computing, linear algebra, or related mathematics
• Deep expertise in LLVM
• Experience with Fortran
• Experience with XLA, Glow, MLIR
• A background in digital signal processing 
• Familiarity with quantum information science
