Senior Compiler Engineer

United States
Systems & Services – QPU Software /
Full-time /
Rigetti Computing is building the world’s most powerful computers to solve humanity’s most pressing problems. We believe this technology will fundamentally change the world for the better and will affect nearly every industry over the coming decades. With over $200M+ in funding, we are looking to expand our Software Engineering capabilities!
Rigetti engineers are a passionate, dedicated team working across multiple scientific and engineering disciplines including RF electronics, cryogenics, superconducting circuits, mechanical engineering, and computer science. We build our software using industry best practices to serve both large enterprise clients and individual researchers around the world.
Rigetti Quantum Cloud Services (QCS) is unique in that it serves access to quantum computers with world-leading capabilities while retaining the agility of a nimble startup, ready and willing to iterate and experiment with new research. In this role, you’ll improve and optimize the compiler all users use to access Rigetti quantum processors. While expertise in Physics or Quantum Mechanics is not an absolute requirement, we hope to find someone who is excited, if not familiar with, supporting and working with scientists, particularly physicists, and hardware engineers. Because this is a highly creative and collaborative role, you will have the opportunity to embody an "inventor" mindset, bounce unique ideas with the team, and own solutions to cutting edge challenges that very few have encountered before. You can also take pride in being one of the few software engineers supporting the development of the world's "next generation" of computing.

As engineering leaders, we value diversity and are committed to building a culture of inclusion to attract and engage innovative thinkers. Our technology, meant to serve all of humanity, cannot succeed if those who built it do not mirror the diversity of the communities we serve. Applications from women, minorities, and other under represented groups are strongly encouraged.

You Are a Great Fit If:

    • You enjoy working across disciplines and are eager to learn from experts outside of your field.
    • You communicate clearly and effectively, and understand domain-driven software design.
    • You take pride in the quality and performance of the software you write, and have experience maintaining software in production.

What You'll Be Doing:

    • Driving and owning the design and development of our system compiler, which transforms quantum programs written in Quil or QIR code into a program ready to execute on a selected quantum processor.
    • Work as a member of a lean team of experts responsible for all public-facing Rigetti applications, and work closely with others to integrate features and changes.
    • Collaborate closely with quantum applications researchers to understand use cases as well as physicists and embedded software engineers to fully exercise the capabilities of custom control hardware.

What You Bring to the Table:

    • Rust and/or C++. Competence in idiomatic Rust.
    • Proven experience writing and optimizing LLVM.
    • Proven experience writing and maintaining compiler software and/or mathematics-centered software.
    • Proven ability to synthesize research findings into resilient, useful software.

Bonus Points If You Have:

    • An advanced degree in mathematics or computer science.
    • Experience with quantum computation or quantum hardware control.
    • Contributions to compilation-related publications and research.
