Senior Software Engineer, Quantum Compilation

United States /
Software Engineering – Software Engineering /
Full-time (Remote)
Rigetti Computing is building the world’s most powerful computers to solve humanity’s most pressing problems. We believes this technology will fundamentally change the world for the better and will affect nearly every industry over the coming decades. We've recently raised our Series C funding and are now expanding our Software Engineering capabilities!

Here at Rigetti, the Software Engineering team's mission is to support and enable the development our proprietary custom Quantum Computing hardware. For this role, you will improve and optimize our execution stack for quantum programs and will work hand in hand with our leading team of physicists and hardware engineers. Your software will sit at the execution point of quantum computation, and as such, you can think of this role as an opportunity to build and define the "operating system" layer of our quantum machines.

While expertise in Physics or Quantum Mechanics is not an absolute requirement for this position, we hope to find someone who has production level compiler experience and a strong foundation in mathematics.

As scientific and 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.

About You:

    • 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.

Role and Responsibilities:

    • You will drive the design and development of our quantum compilation software, which adapts Quil code into a program ready to execute on a selected quantum processor. This software performs mathematical transformation and optimization of quantum programs.
    • You’ll be a member of a small team of experts responsible for all public-facing Rigetti applications, and work closely with others to integrate features and changes.
    • You’ll work at the intersection of many teams. You will partner with quantum applications researchers to understand use cases, collaborate with embedded software engineers to optimize for runtime performance, and work alongside full-stack engineers on web service integration.

Key Qualifications:

    • Fluency in Python, our common language across domains
    • Experience writing and maintaining compiler software and/or mathematics-centered software
    • Proven ability to synthesize research findings into resilient, useful software
    • Advanced degree in mathematics or computer science

Preferred Qualifications:

    • Competence in any of: C++, Golang, gRPC, PostgreSQL, Rust, and/or Common Lisp
    • Contributor to compilation-related publications and research
    • Experience in RPC API design and construction

Why You Should Join:

    • Opportunity to think creatively, bounce ideas, and design software alongside world-class scientists
    • Opportunity to come up with unique solutions for technical challenges that very few have encountered before
    • Ability to leverage cutting edge scientific research in your day to day work and build systems that enable and inspire further groundbreaking research
    • Can take pride in being one of the few software engineers supporting the development of the world's "next generation" of computing
